- **React and Vanilla JS**: Enhance your site with interactive components, first using React, then refactoring with Vanilla JS for optimal performance.
- **Backend Integration**: You'll dive into back-end functionality, creating custom API endpoints, and interfacing with a database using Drizzle ORM to manage your content behind the scenes.
- **Dynamic OG image generation**: Every content website needs decent OG images for social sharing. You’ll learn how to dynamically generate the OG images for your pages and blog articles.

By the end of this course, you won't just have a theoretical understanding — you'll have a live, deployable full-stack blog that reflects current best practices in web development. You’ll also gain valuable and easily-transferrable skills for working with databases and containerizing and deploying full-stack web apps. This course is about building something tangible that you can use as a springboard for more complex projects down the line. So, let's learn how to build great content websites!

Astro is a flexible web framework that allows you to build fast websites to suit your needs.

By default, Astro will build your site using Static Site Generation (SSG). This means the data in your site is loaded at build time so that the end-user gets served static pages that load quickly.

While Astro defaults this way, it also has Server-Side Rendering (SSR) that you can enable if you have more serverful needs in your application.

Along similar lines, Astro utilizes HTML and the browser as a default but when you need more flexibility you can opt into an Astro Island. Islands use React, Vue, Angular, or any frontend JavaScript framework you are used to enhance the user experience in your site.

Build a Full Stack Blog with Astro

An easy to implement, adaptable authentication and authorization platform which basically makes your login box awesome.



auth0

Secure React User Authentication with Auth0

Auth0 Actions are serverless developer tools you can use to customize Auth0.

Actions allow developers to extend Auth0 beyond what it can do out of the box by adding logic to login, user registration, password changes, and other events.
You can quickly solve complex identity problems without hosting your own environment, and worrying about performance, maintenance, and security. Your code is stored and runs on infrastructure owned and maintained by Auth0.

Actions are JavaScript functions that run as part of a flow.  Action integrations can be installed in the Dashboard, or Actions can be written directly in the Dashboard’s JavaScript code editor.

With the  drag-and-drop flow editor, you can visually arrange Actions to build custom identity flows. You don’t have to rewrite your code to reorder and reconfigure functions.

Follow along with Will Johnson as you download a sample application configured with Auth0, then write code for several Actions.

Some examples of Actions you can create:

- Block access from certain counties with an Action from the Auth0 marketplace. 
- Use an npm package and secrets to send a Slack message.
- Redirect users to an a URL after login and back to Auth0 

This course will give you a solid foundation to start developing your own Actions.


Custom Authentication Flows for Modern Applications with Auth0 Actions

Gulp is a toolkit for automating painful or time-consuming tasks in your development workflow, so you can stop messing around and build something.

gulp

Building upon the `watch` task that we begin this lesson with, we’ll look at how to create a local development server using the `app` directory as the web root. By using Browsersync to achieve this, we can also instruct all connected browsers to automatically reload each time our bundle is re-generated. Browsersync has a public `.stream()` method that is designed exactly for this purpose.

Gulp and Browserify - Adding Live Reload with Browsersync

Babel has support for the latest version of JavaScript through syntax transformers. These plugins allow you to use new syntax, right now without waiting for browser support.

babel

What is already a nice workflow using Gulp, Browserify, Watchify & Browsersync to enable auto rebuilds & live browser reloading can be further improved by adding Babelify. A simple wrapper around the popular transpiler Babel, Babelify can ‘transform’ source files as they pass through our stream to enable certain Javascript features not yet available in the Browser or Node. We end the lesson by looking at how to generate & extract sourcemaps using `exorcist`.

Gulp and Browserify - Adding Babel & Source Maps

Browserify lets you require('modules') in the browser by bundling up all of your dependencies.

browserify

Let's look at the basics of setting up Gulp and Browserify. Creating a Gulp task from scratch, we'll cover how to utilise the Browserify API to generate a single `bundle.js` file, catch and log any errors that occur in the compilation process, transform the stream into a format that can be consumed by `gulp.dest` and finish by writing the bundle to a `dist` directory.

Gulp and Browserify - Initial Setup

A brief introduction to using GulpJS in your JavaScript application and creating your first Gulp task.

Installing and Writing a Default Task with Gulp

Beginning with a single Gulp task capable of generating a one-time Browserify bundle, we enable file-watching and incremental rebuilds by incorporating Watchify. We add a second task `watch` & refactor our initial code to enable the bulk of it to be re-used. We’ll look at exactly how to ‘wire’ these tools together and how the relationship between Watchify & Browserify can manifest into a seriously efficient workflow.

Gulp and Browserify - Hooking up Watchify

We will look at bundling your JavaScript files using Gulp, Gulp-Concat, and Gulp-Uglify

Bundling Your JavaScript Files with Gulp

Sign up for a free Auth0 account. A new Auth0 account creates a [new tenant](https://auth0.com/docs/get-started/auth0-overview/create-tenants) within the Auth0 Dashboard the tenant will house your applications connections and user profiles.

Create an Auth0 Account

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

node

Create a new application with the Auth0 CLI with the `auth0 apps create` command.

Name the application, create a description, and select the application type.

If you don't have an application set up with Auth0 you can run `auth0 quickstarts download` to download a sample application that's already configured with Auth0. 

Once the quickstart is downloaded open your code editor and open `src/auth_config.json` file and copy the domain and clientId from the settings inside the Auth0 dashboard, if they aren't population already.

Run `npm run start` to load the application on `localhost:3000` and test out the login flow.

Create New Auth0 Application and Download Quickstart

With Actions you have the option to use pre-configured Actions from the [Auth0 Marketplace](https://marketplace.auth0.com/features/actions).

Add the [Country-based Access](https://marketplace.auth0.com/integrations/country-based-access) Action to your Action library to restrict users access based on their country. 

Once the Action is added to your library, choose the Login flow trigger. Use the drag and drop flow editor to add the Country-based Access Action to the Auth0 login flow.

Add Action from Auth0 Marketplace To Restrict Access By Country

Add a custom field to the users metadata with the [Pre User Registration trigger](https://auth0.com/docs/customize/actions/flows-and-triggers/pre-user-registration-flow).

In the Actions editor enter the following code
```js
exports.onExecutePreUserRegistration = async (event, api) => {
  api.user.setUserMetadata("favorite_ninja_turtle","raphael" )
};
```
This action uses the [API object](https://auth0.com/docs/customize/actions/flows-and-triggers/pre-user-registration-flow/api-object) to add the new metadata before the user is saved to the database

To learn more about Auth0 user metadata [read the docs here](https://auth0.com/docs/manage-users/user-accounts/metadata)



Write Action To Add Metadata To A New User Profile

After a user successfully logs in, Auth0 sends an ID token to your React application. You can use the data from the ID token to personalize the user interface of your React application. ID tokens issued by Auth0 are [JWTs](https://jwt.io) and you can add custom claims to the JWTs using Actions.

Create a Login Action to add the user metadata as a customer claim. 


```js
exports.onExecutePostLogin = async (event, api) => {
  const namespace = `https://myapp.example.com`
  const { favorite_ninja_turtle } = event.user.user_metadata

  if (event.authorization) {
    api.idToken.setCustomClaim(`${namespace}/favorite_ninja_turtle`, favorite_ninja_turtle)
  }
};
```
Auth0 allows namespaced and non-namespaced claims.To avoid name collisions, we recommend using namespaced claims. 

You can use any non-Auth0 HTTP or HTTPS URL as a namespace identifier.

Use a URL that you control as a namespace identifier; this allows you to avoid the risk that someone else is using the same namespace. The namespace URL does not have to point to an actual resource. It is only used as an identifier; it will not be called.

The JWT returned to the requesting application is built and signed at the end of the trigger running. The final, signed JWT is not accessible in an Action.

Check out the docs to learn more about [creating custom claims](https://auth0.com/docs/secure/tokens/json-web-tokens/create-custom-claims)

Add a Custom Claim To Auth0 JWT Id Token

Download the Auth0 CLI on a Mac with homebrww with the command `brew tap auth0/auth0-cli && brew install auth0` 

For download instructions for Windows or Linux check out the [Auth0 CLI's README](https://github.com/auth0/auth0-cli)

When the CLI is installed use the command `auth0 login` to connect the Auth CLI to your Auth0 tenant. 

Install and Connect the Auth0 CLI to Auth0 account

Add the `slack-notify` npm package from the Actions editor to send a Slack message when a new user registers for your application. 

Create a Post User Registration action.

Go to `api.slack.com` create a new app, active **Incoming Webhooks**, and get your Slack Webhook URL.

> Your webhook URL contains a secret. Don't share it online, including public Git repositories.

In the Action editor store the Slack Webhook URL as a secret and add the `slack-notify` npm package.

In the Actions editor enter the follow code:

```js
const initSlackNotify = require('slack-notify')

exports.onExecutePostUserRegistration = async (event) => {
  const slack = initSlackNotify(event.secrets.SLACK_WEBHOOK_URL);
  const message = `New User: ${event.user.email}`

  slack.success({
    text: message
  })
};
```
Before deploying test out the Action by click the Test icon. Once test is successful click deploy.

Then click **Add to flow** and drag the Action into the Post User Registration flow.

Add NPM Packages and Store Secrets with Auth0 Actions

You can use the post-login Action to redirect users before an authentication transaction is complete. This lets you implement custom authentication flows that require additional user interaction beyond the standard login form.

Call `api.redirect.sendUserTo()` with the URL you want to redirect to as a string

After the redirect, in your app resume authentication by redirecting the user to the `/continue` endpoint and include the `state` parameter from the URL. 

If you don't send the original state back to the `/continue` endpoint, Auth0 will lose the context of the login transaction and the user will not be able to log in.


In your application redirect to: `https://{yourAuth0Domain}/continue?state=abc123`

After the user has been redirected to the `/continue` endpoint, the Action will resume by calling the `onContinuePostLogin` function. 

For redirects to work properly, you must have a uncomment the `onContinuePostLogin` function even if the function is empty.

Check if the user has seen the announcement 

```js
  if (!event.user.app_metadata[''announcement_seen'']) {
    api.redirect.sendUserTo("http:://localhost:3000/announcement");
  }
};
```

If the user hasn't seen the announcement set the `app_metadata`

```js
exports.onContinuePostLogin = async (event, api) => {
  api.user.setAppMetadata('announcement_seen', true);
};
``` 


Redirect User After Login with Auth0 Actions

A blog isn't worth much if you don't have a place to put your content. In this lesson we'll dive deep into Astros content collections API which is a feature for organizing all of your content and ensuring when you create your content you add the proper data to your front matter.

To do this we'll create a content folder that contains a `config.ts` inside that config we'll use `defineCollection` from `astro:content` to declare what our blog data will look like. From here you can set a `schema` property and use zod to declare the shape of the data you'd like your content to be in. 

When actually creating content, Astro will throw errors if you miss an attribute in your frontmatter that was set in your schema.

Astro also gives you an easy way to grab all the content you have with the `getCollection` function. We'll use this function to add links to our latests blog posts on the home page.

Create Astro Content Collections with Zod for a Typesafe Blog

We'll set up our initial Astro blog using Houston, Astro's official CLI.

After stepping through the CLI options you'll get a tour of the generated files that Astro includes in a new project. You'll see what file structure you are working with and also get an introduction to the `.astro` file type where we will be doing a lot of the work in this course.

Create an Astro Project and Set up the Dev Environment

From laying down the foundation to adding advanced features, this course walks you through creating your own personal blog website with Astro. Explore backend integration, optimization techniques, and deployment strategies.

In this course, you'll create dynamic OG images, RSS, sitemap, and database all while shipping minimal JavaScript for a blazing-fast user experience.

Intro: Build a Full Stack Blog with Astro

RSS feeds are a way for others to consume your content in their own feed without having to go to your website every time you publish a piece. 

Astro gives you a package `@astrojs/rss` that helps you create such a feed. On the Astro side, this will be an API route which we haven't touched on yet in this course but just know this is a route that others can hit to give them data, in this case a feed of all your posts.

Here we'll export a GET function that will return an RSS feed. RSS feeds require a certain shape to their data which is what we will provide the function. We'll give it a title, description, site, and items.

The items we'll grab from a call to `getCollection` and each will have a title, description, publication date, link, and content. For the content, we are rendering the full post as html. To do this safely we will need to packages: `markdown-it`, and `sanitize-html`. `markdown-it` will take our markdown and produce html and `sanitize-html` will strip out any unnecessary HTML.



Generate an RSS Feed for an Astro Blog with @astrojs/rss
