Master advanced user search with Prisma: Write raw SQL queries, iterate from basic search to SQLite database display.

Search users with Prisma raw queries by criteria, handle TypeScript hurdles, prep for adding images.

User Search with Prisma and SQL

[00:00] So this is our user index page, let's pull that up. And we're gonna swap out this, get rid of that nonsense. And we'll come up here, switch this for Prisma. And then we can say our users, cost users equals await Prisma query raw.

[00:19] And here we go, we've got our raw query going. And what we're gonna do is first select ID, username and name from the table called user. You can put it in quotes, you don't have to, but it will work either way. Where the username is like the search term or the name is like the search term.

[00:39] That to me looks super duper funny. And so what I do instead is I'm gonna make a like variable that is a string that interpolates the search term. And that just, to me that looks a little bit nicer. So now I can say where username like the like or name is like the like.

[00:57] So with that, we now can just add the limit of 50 and we've got our query. Now TypeScript's not gonna be super jazzed about all of this, what we're doing right here. Also, we don't have the image quite yet, we're gonna get to that later. So we'll just pass this along. And again, like I said,

[01:16] TypeScript's not gonna like this a whole lot just because the way that we have our, there's, you cannot get a type from a raw query with Prisma like this. It just is not possible with Prisma. So we're gonna have to deal with that later. So we're getting no user found

[01:34] because the search term is gonna be null because we don't have a search term. But if I search for KO and we're gonna get Cody there. So let's fall back to an empty string. So if there isn't a search term, then it will be like empty string. And now we're gonna get all of our users there.

[01:52] Ta-da, looks great. And we're not getting any images right here because we're not selecting our images, that's for a future step. So just to review the stuff that we've done, we created a like, which includes these percentage signs that is a special syntax in SQL to say

[02:13] that this is like a string containing this value. That's what we're looking for. And then we have our query raw with our template literal. We have select ID, username and name from user where username is like that like syntax or the name is like that. And then we're gonna limit to the top 50.

[02:32] Of course we could limit to two. And if we do that and we're only gonna get two. But I think 50 results on this page is fine. That's what our product manager said. And again, our TypeScript's not super jazzed, but we'll deal with that later. So we're all ready for the next step.

SQL Queries for User Search in Prisma

[00:00] we still have one more place where we're still using the in-memory database instead of the actual database, and that's our user search page. So that is your job. You need to add the SQL query that is going to search users. This is going to be a little bit more complicated because you

[00:17] can just use regular Prisma to query the way that we're doing. But our product manager has a couple of interesting requirements that they want us to do. So we're going to actually write raw SQL in this exercise. So it's going to be a little bit, if you haven't done any SQL before,

[00:35] but Prisma has a really great way to execute a query safely, so you don't have to worry about escaping things, and it has this $query raw thing and it's a tag template, literally just like insert stuff and it'll escape it. It's awesome. So that's what you're going to be doing in this exercise. We've got a couple of steps to

[00:52] iterate to the final solution that our product manager wants us to have. But for this first step, we're just going to do a basic search so that when you search for Cody, it shows up Cody. When you are finished, we should actually be able to see multiple users on this page because

[01:09] our database that's the actual SQLite database does have multiple users in there. Right now, we're only seeing one because in our in-memory database, we only have one. So get to it. Let's get going.

Data modeling is as a critical skill for the full stack developer. After all, data is the foundation of your application.

If you don't do it right, you'll find yourself stuck before you even get started. A poorly designed database schema can lead to a lot of headaches down the road when you need to make changes or add new features. Inefficient queries can slow down your application, leading to a poor user experience. Analyzing root causes to issues like these can be a time-consuming and frustrating process.

Web developers spend a ton of time into making their UI handle a slow backend well which is great and you should do that too (you don’t control network latency after all). But *****great***** web developers put effort into making it so their users hardly ever experience that great pending UI by making the backend as fast as possible. Your UI can’t be any faster than your slowest database query.

The Data Modeling Deep Dive Workshop will help you develop a keen understanding of databases and how to manage them. You'll learn the same tools and techniques used at the top tech companies to design robust database architectures and optimize query performance.

We'll be using production grade tools like Prisma and SQLite, but the concepts you learn in this workshop will be applicable to other database systems as well.

## Database Schema

A well-designed database schema is the foundation of your application. It's critical to get it right from the start, as it can be difficult to make changes down the road. This section provides a background on SQL before introducing Prisma's suite of tools. You'll learn:

- SQLite database initialization with Prisma
- Prisma's Object Relational Mapper (ORM)
- Defining a schema with Prisma's declarative schema language
- Converting a schema to SQL with the Prisma CLI
- Viewing and editing your database in Prisma Studio

## Relationships

Poorly planned relationships between database models can lead to data inconsistencies and increased query complexities and performance problems. To avoid these issues, you need to understand the different types of relationships and how to implement them. This section provides you with practical experience in recognizing relationships:

- One-to-many relationships (User has many Notes)
- One-to-one relationships (User has one UserImage)
- Updating the database with Prisma
- Planning models for the future
- Generate an Entity Relationship Diagram (ERD) for visualization

## Migrations

As your application evolves, so will your database schema. It's not uncommon for there to be "breaking changes" that affects one or more of your database models. This is where migrations come in.

Migrations allow you to track and synchronize schema changes across environments. Traditionally migrations have been tricky to manage, but this section will teach you how to use migrations to ensure your development, staging, and production environments are always in sync:

- Generating SQL migration code with Prisma
- Best practices for documenting & tracking migrations
- The "widen then narrow" approach for eliminating downtime
- Experimenting with migrations before permanently applying them

## Seeding Data

Manually adding data to a database is not only time-consuming but also prone to errors. Scripting to the rescue!

Here you'll learn how to populate your databases with consistent data for development and testing purposes:

- Initializing a SQLite database
- Idempotent scripting
- Resetting the database with Prisma
- Nesting SQL queries to simplify foreign key connections

## Generating Seed Data

Using hardcoded seed data works great for small applications, but it won't provide the best idea of how your application will perform at scale. You also shouldn't use real user data during development for plenty of obvious reasons.

A better approach is to use a library like Faker.js. This section will teach you how to use Faker.js to generate seed data for your database:

- Balancing realism with practicality when generating data
- Creating realistic user information
- Varying data quantities and randomness
- Validating against the schema
- Enforce data uniqueness

## Querying Data

In SQL, queries are written with the `SELECT` statement. This is one of the most powerful statements available, but it can also be one of the most complex. This is where tools like Object Relational Mappers (ORMs) come in, helping developers write SQL in a more intuitive way. Although it isn't a traditional ORM, the Prisma Client is an indispensable tool for modern web development. In this section, you'll learn how to get the most out of it:

- Understanding how Prisma's API maps to SQL
- Handling Hot Module Replacement (HMR)
- Logging slow queries
- Pre-connecting the client to the database

## Updating Data

Data mutation is a common task, but doing it incorrectly can lead to data corruption or loss. Especially when a single user action results in multiple database changes (for example, transferring money between user’s bank accounts). Getting mutations wrong can be a serious problem for your app’s success. This section will walk you through techniques for working safely:

- Deleting and updating data
- Conditional upserts
- Combining multiple queries into a transaction
- Rolling back to a previous transaction

## SQL

No matter how great an ORM is, sometimes you have to write raw SQL. In this section, you'll learn how to write raw SQL queries and execute them with Prisma. You'll also practice with:

- Wildcard queries
- Runtime schema validation with Zod
- Using joins to enable more complex queries
- Specifying query result ordering for more efficient searching

## Query Optimization

Nobody likes a slow application.

There are many stories of companies spending millions of dollars on scaling hardware, adding multiple levels of caching, and even rewriting their entire application in pursuit of a faster performance– only to find out later that the solution was optimizing their database indexes and queries.

In this final section, you'll learn how to optimize your queries for maximum performance:

- Identifying the index
- Analyzing raw SQL queries
- Multi-column indexing
- Balancing premature optimization with practicality

The Data Modeling Deep Dive Workshop will teach you best practices for designing database schemas, managing relationships, data mutations, and optimizations.

Data Modeling Deep Dive

Kent C. Dodds

Developers working on modern web applications today face a myriad of challenges.

The apps we build are expected to be good looking, fast, and secure. They need to be interactive, responsive, and accessible. They need to be SEO-friendly, and they need to be resilient to errors.

In order to be successful, you need to ensure you have a solid foundation to build on.

Full Stack Foundations is a comprehensive, in-depth workshop that sets the stage for the rest of the Epic Web series. It's designed to equip you with the current best practices for handling CSS, routing, data loading, and more.

This isn't some basic "intro" workshop! Even if you're an experienced developer, you'll learn new skills and techniques that will help you build better apps.

<Testimonial author={{name: "Gwen Shapira"}}>

It was 🤯. A lot of fun, and I learned so much in one day. Even with 23 years as a software engineer, I have a much clearer understanding of how the web actually works. Now, months after this workshop, I’m working on a web project and this gave me the mental framework I needed to quickly ramp up and feel competent. I’m not even using the same tools Kent uses in the workshops! 13/10.

</Testimonial>

## Styling

In recent years, CSS has seen a lot of evolution in its usage and tooling. There are new best practices for importing stylesheets, managing assets, and optimizing styles. Failing to follow them can lead to slow-loading pages and a maintenance nightmare.

Here, you'll learn how to handle styling right:

- Loading external stylesheets & other resources
- Managing assets with fingerprinting and caching
- Compilation with PostCSS and Tailwind CSS
- Bundling CSS for libraries and components

## Routing

The URL is critical for the web, and is closely tied to your application's routing. Making suboptimal decisions affects loading performance, navigation, and overall experience.

This section is a deep dive into routing, from the basic filesystem structure through nested routes and dynamic parameters:

- Conventions for signifying routes
- Layout and URL nesting
- Navigation and linking
- Dynamic route params
- Resource routes

## Data Loading

The web is all about data, and nothing frustrates users more than when loading is slow or broken. This section introduces you to AJAX/fetch and Remix loading features, giving you the tools to build stable, fast-loading applications:

- Working with `Request` and `Response` objects
- Fetching data for initial and subsequent loads
- Accessing environment variables
- Connecting routes to loaders

## Mutations

Interactivity makes apps engaging, but also introduces complexity. You need to ensure that the thing that happens when a form is submitted is what the user expects. Here you will use form methods and actions to mutate existing data in a mock database:

- Creating forms with `method` and `action`
- Storing and extracting form data
- Handling invalid submissions
- Form state management
- Specifying intent

*This module sets the stage for the complete Professional Web Forms workshop.*

## Scripting

The browser is capable of quite a lot on its own. Up until this point of the workshop, the Epic Notes application will work without any JavaScript. However, scripting allows us to enhance the user experience in ways that would otherwise be impossible.

In this section, you'll incrementally add in features like client-side pending UI, prefetching, and optimistic updates:

- Scroll position restoration
- Considerations when overriding default browser functionality
- Server and client bundles & entry files
- Preloading data & code for anticipated actions
- Transitions with the `useNavigation` hook

## Search Engine Optimization

Ignoring SEO is like building a store without a sign— people simply won't find you. If you want to be successful, your site needs to be discoverable and optimized for presentation on those platforms.

SEO is a very broad topic, but this section will get you set up on the technical side of the equation:

- Essential tags and attributes
- Overriding default metadata for specific pages
- Dynamically set metadata for social sharing
- Reusing parent data for nested routes

## Error Handling

Even the best apps can break, but what separates the good from the great is how they recover. Lack of proper error handling can lead to frustrated users and lost business.

This section will teach you how to anticipate, handle, and recover from errors, making your application resilient and user-friendly.

- HTTP status codes
- Using `ErrorBoundary` components to contain errors
- Handle thrown errors when fetching data
- Error bubbling from child routes to parent routes
- Implement useful 404 pages

Full Stack Foundations

Forms are the primary mechanism for interactivity on the web.

But for all of their importance, forms can be incredibly frustrating for developers and users alike.

There are a lot of moving parts to consider: 

You need to validate user input and handle complex data structures, while being secure from bots and data-stealing attacks. The UI should inform users of any issues as quickly as possible, and be accessible for all.

The Professional Web Forms Workshop will equip you with the tools to handle all of these challenges and more.

## Form Validation

HTML has several attributes built-in that help with form element validation. Unfortunately, they're not enough on their own. On the client-side, bad actors can bypass checks by manually adding the `novalidate` attribute or making requests directly. On the server side, there's no standard way to respond to validation errors other than a generic 400 status code.

In this section, you'll implement a base level of form validation:

- Essential HTML attributes for validation
- Server-side validation with JSON responses
- Displaying errors with the `useActionData` hook
- Disabling default browser validation messages with `useHydrated`

## Accessibility

Accessibility is often an afterthought, but should be a priority. While forms are just one part of the accessibility equation, they're a big one. In this section, you'll learn how to make sure your forms accessible and usable by all of your application's users:

- Properly associating labels with input fields
- Adding appropriate ARIA attributes when necessary
- Manage keyboard focus in response to errors and user interactions
- Creating and using a `useFocus` hook to direct the user’s focus
- Considerations for accessibility testing

## Schema-Based Validation

Manually writing conditional checks for every field in every form is tedious and error-prone: *Is there content in the field? Is it the right type? Is it within the acceptable range? There must be a better way!*

Fortunately, the combination of the Zod and Conform libraries makes it easy to define reusable declarative schemas to validate form data on the client and server:

- Safely replace HTML validation attributes with schemas
- Zod error handling & message customization
- Progressively enhanced validation with Conform
- Share type-safe validation logic between client and server

## File Uploads

Forms need to support more than just text. Images, videos, audio files, and other documents need a different type of input. Depending on the size of the file, you'll have considerations for how and where it is uploaded. In this section, you'll learn how to handle file uploads in a secure and efficient way:

- Uploading images from an `ImageChooser` component
- Handling file uploads on the server
- Schema validation for file uploads with Zod

## Complex Data Structures

The `FormData` API does not support representing objects or arrays– only key/value pairs. It also won't allow you to nest forms within each other. This makes representing complex data structures difficult without jumping through some hoops. Luckily for us, Conform has a great solution when your forms get complex. Here you'll practice:

- Infer field types with Zod
- Nesting objects as a form
- Represent arrays of fields with the `useFieldList` utility
- Add and remove items with Conform's `intent` buttons

## Spam Prevention with Honeypots

Spam bots are constantly crawling the web, looking for forms to submit junk data to boost their client’s search engine rankings and find holes in your security. This can strain server resources, contaminate databases, and cause other unforeseen consequences. One way to combat this is by using a "honeypot", which will prevent a form from being submitted by a bot. This section will teach you how to:

- Create a simple hidden-field validation
- Add a configurable honeypot instance to an action
- Prevent form submissions that are too fast
- Use environment variables for encryption seeds

## CSRF Protection

Cross-Site Request Forgery (CSRF) attacks are a type of malicious exploit where a user is tricked into performing an action they did not intend to. This is usually done by embedding a link or form in a page that the user is already authenticated to. Think of a user logged into their bank account clicking a link that transfers money from their bank account to the attacker's. To prevent this type of attack, you'll want to:

- Create a signed cookie in the user's browser
- Include unique user tokens in forms
- Validate tokens on the server via request headers

## Rate Limiting

You definitely want to prevent bad actors from making tons of requests to try to brute-force their way into your app or cause general chaos. However, malicious intent and spam aren't the only reasons you need to protect your site. Even too many legitimate requests can cause problems. Rate limiting is a way to prevent users from overloading your server with requests. Here you'll learn:

- Considerations for different limits for `GET` vs. `POST` requests
- Implementing basic rate limiting with Express middleware
- Tiered rate limiting depending on which form is being submitted

Professional Web Forms

Most web applications feature user accounts in one form or another.

To the user, having a login form seems simple enough. But behind the scenes, there's a lot going on. You need to securely store and manage user sessions, handle authentication and authorization, and protect against malicious attacks.

Without knowledge of the underlying concepts, it's easy to make mistakes (even if you decide to use a third party service or library to do all the hard work for you). Weak authentication systems, misconfigured route protection, and flawed session management all lead to vulnerabilities and negative user experiences.

The Authentication Strategies & Implementation workshop is your guide to implementing industry standard user account flows in a modern web application.

Securely managing passwords, enabling two-factor authentication, and integrating with third-party providers are just some of the processes you will practice. You'll also learn how to handle user preferences, session data, and send emails to users. This will take you all the way to the point where you could easily add Single-Sign On (SSO) support–a must if you’re building a business-to-business application.

There are a lot of moving parts to consider, but this workshop will give you the confidence to tackle them all.

## Cookies

The workshop begins by diving into cookies. This fundamental part of web browsing is often misunderstood, but important to understand. We keep it simple to ramp you up slowly on the web’s original state management solution. This also introduces us to important UI patterns you’ll want to use in other areas of web development as well. It’s surprisingly deep! Topics include:

- Storing user theme preferences in a cookie
- Server-side cookie handling
- Using fetchers for non-navigation mutations
- Optimistic UI updating to apply changes immediately

## Session Storage

Storing user preferences in cookies is fine, but you need to be more careful when it comes to session data. It's vital that users with devtools or malicious client-side JavaScript can't access or modify the data inside of cookies. In this section, you'll learn:

- Cookie-based session data persistence
- Properly getting, setting, and updating session data
- Deleting data after reading
- The flash pattern for short-lived messages

## User Sessions

Depending on the amount of data you need to store, it may make sense to use a different storage mechanism for session data. For this workshop we will continue to use cookies, however we will switch to using a dedicated session cookie. This section will teach you:

- Create a session storage object for storing user data
- Transform form submissions into user objects for storage
- Retrieving user information from cookies then the database

## Passwords

Passwords are the most common way to authenticate that a user is who they say they are. Obviously, storing them in plain text is a bad idea, but even encryption isn't enough. You need to properly prepare to securely handle passwords:

- Create a Password model in the database
- Generate secure password hashes with the battle-tested bcrypt algorithm
- Protection against password attacks
- Update signup route to securely create records

## Login & Logout

At this point, you have the ability to create users and store their passwords. But how do you actually log them in? And how do you log them out? In this one we’re also going to learn about imperative mutations which you’ll definitely want to know for other app features. This section will teach you:

- Verify a user's password hash with bcrypt
- Handling optional vs. required user data
- Guard against timing attacks
- Clearing session data on logout
- Handle edge cases like deleted accounts
- Set expiration dates for session cookies
- Implement automatic logout after a set idle time

## Protecting Routes & Role-Based Access

Most web application have routes that you need to be logged in to access. It's one thing to prevent this in the UI, but the real thing you need to do is protect the data that powers those pages. There are also considerations for different user roles and permissions. This section will teach you how to:

- Ensure users only access data they own
- Restrict private pages to logged in users
- Implement smart redirects for login and logout
- Specify and enforce permissions with Role-Based Access Control (RBAC)

## Managed Sessions

Imagine a user logging in on a public computer, who then forgets to log out. This security risk can be mitigated by implementing a session management feature:

- Add a session model to the database
- Update auth utils, login, and logout routes to query sessions
- Refactor for session expiration support
- Create a page for displaying & managing active sessions

## Email Verification & Password Resets

Email is one of the most common ways to verify a user's identity. If a user loses access to their account, needs to reset their password, or wants to change their email address, you'll need to send them an email. While the actual sending of the email is best handled by a third-party service, the process flow behind the scenes is what you'll need to implement:

- Integrate a third-party email API
- Share session data between routes for multi-step flows
- Style HTML emails
- Generate time-based one time passwords (TOTP) for password resets
- Force verification of email address change

## Two-Factor Authentication

Two-factor authentication (2FA) is a great way to add an extra layer of security to your application. It requires the user to enter a code from a second device along with their username and password. Even if an attacker determines a password, they won't be able to access the account without the second factor. In this section, you'll add 2FA to the Epic Notes application:

- Handle the 2FA enable flow
- Provide the user with a QR code
- Implement a 2FA code input form
- Verify the code and log the user in
- Require re-verification
- Provide option to disable 2FA

## Third-Party Authentication

There are several reasons to use third-party authentication providers. It can be a great way to reduce friction for users, or allow easier access to other data. The most common way to do this is with OAuth 2. Once you’re finished with this section, you’ll be geared up to implement third party auth with any provider. Including Single-Sign On (SSO) flows. We’ll be following these steps:

- Add an authentication strategy to enable GitHub login
- Create a connections model to associate users with providers
- Prevent duplicate account connections & hijack attempts
- Pre-fill user account data based on third-party login
- Mocking third party APIs for testing
- Gracefully handle login errors
- Implement smart redirection to return to original page after login

Authentication Strategies & Implementation

We all know the drill. The code works on your machine but you didn’t realize the impact of the change you made and it breaks in production. This problem grows exponentially as your application’s size and usefulness grows. Unpredictability can be a developer's worst nightmare.

However, many developers find it difficult to effectively test their code. Manual testing gets tedious fast. Complex logic and async code can be tricky to test effectively.

The Full Stack Testing Workshop will equip you with the tools you need to ensure your app works now and in the future. You'll learn how to write modular, maintainable tests that cover all of your code, from the backend to the frontend.

As the author of the de-facto standard testing library for web development (called eh… Testing Library), I have some solid opinions that have led many teams to much more confidence shipping their code. Let’s get you some of that confidence.

## End-to-End Testing with Playwright

With end-to-end (E2E) testing, you can validate a web app from the user's perspective. This is the closest you can get to a real user interacting with your app. In this section, you'll learn the ins and outs of writing a test with Playwright:

- Best practices for setup before running tests
- Simulating user actions like interacting with the UI to perform a search
- Creating a new user in the database
- Cleaning up after tests have run
- Using playwright fixtures for reliable setup/teardown

## Mocking & Authentication for E2E Tests

When your application relies on external services, you need to have a way to test them without actually using them. Similarly, you don't want to fully onboard a new account every time you test an authenticated user flow. In this section, you'll learn how to re-use the same mocks we’ve been using for development to mock third-party services and simulate logging in:

- Use Mock Service Worker to intercept network requests
- Replace email verification with a local file solution
- Attach cookies to Playwright
- Reusing 2FA logic for local testing
- Testing behavior with different HTTP responses

## Unit Testing

Sometimes you’ve got some really complicated business logic in your app. Business logic that is critical to your application. For this stuff, it’s nice to package it up in its own function or module to keep all that logic in one place. This is the perfect situation where lower level unit testing comes in handy. Here, we'll dive into unit testing with the Vitest framework to ensure that each function and module behaves as expected:

- Organizational best practices
- Asserting outcomes with `expect`
- Recording function calls with spies
- Specifying test behavior with Vitest hooks
- Keeping test output clean to avoid cluttering up the terminal

## Component and Hook Testing

When building React components, you should focus on two users: the user who interacts with a component, and the developer who renders it. By using Testing Library, we can avoid mocking React and its hooks and instead test components as they would be used in a real app:

- Render components with Testing Library
- Simulate the DOM environment on a per-test basis
- Querying for missing elements
- Testing hooks in isolation from React
- Stubbing React context
- Cleanup after testing

## Authenticated Integration

Similar to higher-level E2E tests, it is often necessary to simulate an authenticated user. However, we don't want to test the entire user flow every time we make a change. In this section, you'll learn how to test authenticated operations without the overhead of a full E2E test:

- Generating random session IDs
- Associating sessions with users
- Testing authenticated routes
- Asserting user state in responses

## Custom Assertions

Writing tests is good; writing readable and maintainable tests is better. Custom assertions can make your test code easier to understand and modify. Here you'll learn to encapsulate complex checks into simple, understandable assertions:

- Create matchers for specific states
- Share assertions across tests
- Add custom assertions to TypeScript definitions
- Format test output with colors for readability

## Test Database

There are some decisions to make when writing tests that interact with the database. Testing with the development database has benefits, but requires us to remember to delete data after each test. By using a test database, we can avoid accidents while still being able to run our test suites:

- Set up a test-specific database instance
- Seeding a minimal amount of data
- Defining a global setup for Vitest
- Understanding the importance of module import order
