-# Releasing Astro
+## Code Structure
+
+Server-side rendering (SSR) can be complicated. The Astro package (`packages/astro`) is structured in a way to help think about the different systems.
+
+- `components/`: Built-in components to use in your project (e.g. `import Code from 'astro/components/Code.astro'`)
+- `src/`: Astro source
+  - `@types/`: TypeScript types. These are centralized to cut down on circular dependencies
+  - `cli/`: Code that powers the `astro` CLI command
+  - `core/`: Code that executes **in the top-level scope** (in Node). Within, you’ll find code that powers the `astro build` and `astro dev` commands, as well as top-level SSR code.
+  - `runtime/`: Code that executes **in different scopes** (i.e. not in a pure Node context). You’ll have to think about code differently here.
+    - `client/`: Code that executes **in the browser.** Astro’s partial hydration code lives here, and only browser-compatible code can be used.
+    - `server/`: Code that executes **inside Vite’s SSR.** Though this is a Node environment inside, this will be executed independently from `core/` and may have to be structured differently.
+  - `vite-plugin-*/`: Any Vite plugins that Astro needs to run. For the most part, these also execute within Vite similar to `src/runtime/server/`, but it’s also helpful to think about them as independent modules. _Note: at the moment these are internal while they’re in development_
+
+### Thinking about SSR
+
+There are 3 contexts in which code executes:
+
+- **Node.js**: this code lives in `src/core/`.
+- **Inside Vite**: this code lives in `src/runtime/server/`.
+- **In the browser**: this code lives in `src/runtime/client/`.
+
+Understanding in which environment code runs, and at which stage in the process, can help clarify thinking about what Astro is doing. It also helps with debugging, for instance, if you’re working within `src/core/`, you know that your code isn’t executing within Vite, so you don’t have to debug Vite’s setup. But you will have to debug vite inside `runtime/server/`.

 ## Using `fetch()` outside of Astro Components

-If you load a component using `node-fetch` [interactively](/core-concepts/component-hydration), with `client:load`, `client:visible`, etc., you'll need to either not use `node-fetch` or switch to an [isomorphic](https://en.wikipedia.org/wiki/Isomorphic_JavaScript) library that will run both at build time and on the client, as the [`node-fetch` README.md](https://github.com/node-fetch/node-fetch#motivation) recommends:
-
-> Instead of implementing XMLHttpRequest in Node.js to run browser-specific [Fetch polyfill](https://github.com/github/fetch), why not go from native http to fetch API directly? Hence, node-fetch, minimal code for a window.fetch compatible API on Node.js runtime.
->
-> See Jason Miller's [isomorphic-unfetch](https://www.npmjs.com/package/isomorphic-unfetch) or Leonardo Quixada's [cross-fetch](https://github.com/lquixada/cross-fetch) for isomorphic usage (exports node-fetch for server-side, whatwg-fetch for client-side).

+## Setting environment variables
+
+Vite includes `dotenv` by default, allowing you to easily set environment variables with no configuration in Astro projects. You can also attach a mode (either `production` or `development`) to the filename, like `.env.production` or `.env.development`, which makes the environment variables only take effect in that mode.
+
+Just create a `.env` file in the project directory and add some variables to it.
+
+```bash
+# .env
+VITE_POKEAPI="https://pokeapi.co/api/v2"
+```
+
+## Getting environment variables
+
+Instead of using `process.env`, with Vite you use `import.meta.env`, which uses the `import.meta` feature added in ES2020 (don't worry about browser support though, Vite replaces all `import.meta.env` mentions with static values). For example, to get the `VITE_POKEAPI` environment variable, you could use `import.meta.env.VITE_POKEAPI`.
+
+```js
+fetch(`${import.meta.env.VITE_POKEAPI}/pokemon/squirtle`
+```
+
+> ⚠️WARNING⚠️:
+> Because Vite statically replaces `import.meta.env`, you cannot access it with dynamic keys like `import.meta.env[key]`.

@ -6,62 +6,140 @@ description: Learn how to style components with Astro.

 Astro includes special handling to make writing CSS as easy as possible. Styling inside of Astro components is done by adding a `<style>` tag anywhere.

-By default, all Astro component styles are **scoped**, meaning they only apply to the current component. These styles are automatically extracted and optimized for you in the final build, so that you don't need to worry about style loading.
+## Astro component styles

-To create global styles, add a `:global()` wrapper around a selector (the same as if you were using [CSS Modules][css-modules]).
+By default, all Astro component styles are **scoped**, meaning they only apply to the current component. This can be very easy to work with, as you only have to worry about what’s in your current document at any given time.

 ```html
 <!-- src/components/MyComponent.astro -->
 <style>
  /* Scoped class selector within the component */
-  .scoped {
-    font-weight: bold;
+  .text {
+    font-family: cursive;
  }
  /* Scoped element selector within the component */
  h1 {
    color: red;
  }
-  /* Global style */
+</style>
+
+<h1>I’m a scoped style and I’m red!</h1>
+<p class="text">I'm a scoped style and I’m cursive!</p>
+```
+
+Note that the `h1` selector won’t bleed out of the current component! These styles won’t apply any other `h1` tags outside this document. Not even child components.
+
+_Tip: even though you can use element selectors, using classnames is preferred. This is not only slightly more performant, but is also easier to read, especially in a large document._
+
+### Global styles
+
+Of course, the real power of CSS is being able to reuse as much as possible! The preferred method of loading global styles is by using a standard `<link>` tag like you’re used to. It can even be used in conjunction with Astro’s scoped `<style>` tag:
+
+```html
+<!-- src/pages/index.astro -->
+<head>
+  <!-- load styles from src/styles/utils.css using Astro.resolve() -->
+  <link rel="stylesheet" type="text/css"
+  href={Astro.resolve('../styles/utils.css')} />
+</head>
+<body>
+  <!-- scoped Astro styles that apply only to the current page (not to children or other components) -->
+  <style>
+    .title {
+      font-size: 32px;
+      font-weight: bold;
+    }
+  </style>
+
+  <!-- the ".title" class is scoped, but we can also use our global "align-center" and "margin top: 4" utility classes from utils.css -->
+  <h1 class="title align-center mt4">Scoped Page Title</h1>
+</body>
+```
+
+_Note: `Astro.resolve()` is a handy utility that helps resolve files from anywhere ([docs][astro-resolve])_
+
+#### Styling children
+
+If you’d like scoped styles to apply to children, you can use the special `:global()` function borrowed from [CSS Modules][css-modules]:
+
+```astro
+<!-- src/components/MyComponent.astro -->
+---
+import PostContent from './Post.astro';
+---
+<style>
+  /* Scoped to current component only */
+  h1 {
+    color: red;
+  }
+
+  /* Scoped to all descendents of the scoped .blog-post class */
+  .blog-post :global(h1) {
+    color: blue;
+  }
+</style>
+
+<h1>Title</h1>
+<article class="blog-post">
+  <PostContent />
+</article>
+```
+
+This is a great way to style things like blog posts, or documents with CMS-powered content where the contents live outside of Astro. But be careful when styling children unconditionally, as it breaks component encapsulation. Components that appear different based on whether or not they have a certain parent component can become unwieldy quickly.
+
+#### Global styles within style tag
+
+If you’d like to use global styles but you don’t want to use a normal `<link>` tag (recommended), there is a `<style global>` escape hatch:
+
+```html
+<style global>
+  /* Applies to all h1 tags in your entire site */
+  h1 {
+    font-size: 32px;
+  }
+</style>
+
+<h1>Globally-styled</h1>
+```
+
+You can achieve the same by using the `:global()` function at the root of a selector:
+
+```html
+<style>
+  /* Applies to all h1 tags in your entire site */
  :global(h1) {
    font-size: 32px;
  }
-</style>

-<div class="scoped">I'm a scoped style and only apply to this component</div>
-<h1>I have both scoped and global styles</h1>
+  /* normal scoped h1 that applies to this file only */
+  h1 {
+    color: blue;
+  }
+</style>
 ```

-To include every selector in a `<style>` as global styles, use `<style global>`. It's best to avoid using this escape hatch if possible, but it can be useful if you find yourself repeating `:global()` multiple times in the same `<style>`.
+It’s recommended to only use this in scenarios where a `<link>` tag won’t work. It’s harder to track down errant global styles when they’re scattered around and not in a central CSS file.

-```html
-<!-- src/components/MyComponent.astro -->
-<style>
-  /* Scoped class selector within the component */
-  .scoped {
-    font-weight: bold;
-  }
-  /* Scoped element selector within the component */
-  h1 {
-    color: red;
-  }
-</style>
+📚 Read our full guide on [Astro component syntax][astro-component] to learn more about using the `<style>` tag.

-<style global>
-  /* Global style */
-  h1 {
-    font-size: 32px;
-  }
-</style>
+## Autoprefixer

-<div class="scoped">I'm a scoped style and only apply to this component</div>
-<h1>I have both scoped and global styles</h1>
+[Autoprefixer][autoprefixer] takes care of cross-browser CSS compatibility for you. Use it in astro by installing it (`npm install --save-dev autoprefixer`) and adding a `postcss.config.cjs` file to the root of your project:
+
+```js
+// postcss.config.cjs
+module.exports = {
+  autoprefixer: {
+    /* (optional) autoprefixer settings */
+  },
+};
 ```

-📚 Read our full guide on [Astro component syntax](/core-concepts/astro-components#css-styles) to learn more about using the `<style>` tag.
+_Note: Astro v0.21 and later requires this manual setup for autoprefixer. Previous versions ran this automatically._

-## Cross-Browser Compatibility
+## PostCSS

-We also automatically add browser prefixes using [Autoprefixer][autoprefixer]. By default, Astro loads the [Browserslist defaults][browserslist-defaults], but you may also specify your own by placing a [Browserslist][browserslist] file in your project root.
+You can use any PostCSS plugin by adding a `postcss.config.cjs` file to the root of your project. Follow the documentation for the plugin you’re trying to install for configuration and setup.

 Svelte in Astro also works exactly as expected: [Svelte Styling Docs][svelte-style].

-### 👓 Sass
+### 🎨 CSS Preprocessors (Sass, Stylus, etc.)

-Astro also supports [Sass][sass] out-of-the-box. To enable for each framework:
+Astro supports CSS preprocessors such as [Sass][sass], [Stylus][stylus], and [Less][less] through [Vite][vite-preprocessors]. It can be enabled via the following:
+
+- **Sass**: Run `npm install -D sass` and use `<style lang="scss">` or `<style lang="sass">` (indented) in `.astro` files
+- **Stylus**: Run `npm install -D stylus` and use `<style lang="styl">` or `<style lang="stylus">` in `.astro` files
+- **Less**: Run `npm install -D less` and use `<style lang="less">` in `.astro` files.
+
+You can also use all of the above within JS frameworks as well! Simply follow the patterns each framework recommends:

- **Astro**: `<style lang="scss">` or `<style lang="sass">`
 - **React** / **Preact**: `import Styles from './styles.module.scss'`;
- **Vue**: `<style lang="scss">` or `<style lang="sass">`
- **Svelte**: `<style lang="scss">` or `<style lang="sass">`
+- **Vue**: `<style lang="scss">`
+- **Svelte**: `<style lang="scss">`

-💁‍ Sass is great! If you haven't used Sass in a while, please give it another try. The new and improved [Sass Modules][sass-use] are a great fit with modern web development, and it's blazing-fast since being rewritten in Dart. And the best part? **You know it already!** Use `.scss` to write familiar CSS syntax you're used to, and only sprinkle in Sass features if/when you need them.'
+Additionally, [PostCSS](#-postcss) is supported, but the setup is [slightly different](#-postcss).

-**Note**: If you use .scss files rather than .css files, your stylesheet links should still point to .css files because of Astro’s auto-compilation process. When Astro “needs” the styling files, it’ll be “looking for” the final .css file(s) that it compiles from the .scss file(s). For example, if you have a .scss file at `./src/styles/global.scss`, use this link: `<link rel="stylesheet" href="{Astro.resolve('../styles/global.css')}">` — **not** `<link rel="stylesheet" href="{Astro.resolve('../styles/global.scss')}">`.
+_Note: CSS inside `public/` will **not** be transformed! Place it within `src/` instead._

 ### 🍃 Tailwind

-> Note that Astro's Tailwind support _only_ works with Tailwind JIT mode.

-
-If you want to import third-party libraries into an Astro component, you can use a `<style lang="scss">` tag to enable [Sass][sass] and use the [@use][sass-use] rule.

-```html
-<!-- Loads Boostrap -->
-<style lang="scss">
-  @use "bootstrap/scss/bootstrap";
-</style>
-```

 ### 🎭 PostCSS

-[PostCSS](https://postcss.org/) is a popular CSS transpiler with support for [a huge ecosystem of plugins.](https://github.com/postcss/postcss#plugins)
-
-**To use PostCSS with Snowpack:** add the [@snowpack/plugin-postcss](https://www.npmjs.com/package/@snowpack/plugin-postcss) plugin to your project.
-
-```diff
-// snowpack.config.js
-"plugins": [
-+  "@snowpack/plugin-postcss"
-]
-```
-
-PostCSS requires a [`postcss.config.js`](https://github.com/postcss/postcss#usage) file in your project. By default, the plugin looks in the root directory of your project, but you can customize this yourself with the `config` option. See [the plugin README](https://www.npmjs.com/package/@snowpack/plugin-postcss) for all available options.
-
-```js
-// postcss.config.js
-// Example (empty) postcss config file
-module.exports = {
-  plugins: [
-    // ...
-  ],
-};
-```
+Using PostCSS is as simple as placing a [`postcss.config.cjs`](https://github.com/postcss/postcss#usage) file in the root of your project.

 Be aware that this plugin will run on all CSS in your project, including any files that compiled to CSS (like `.scss` Sass files, for example).

+_Note: CSS in `public/` **will not be transformed!** Instead, place it within `src/` if you’d like PostCSS to run over your styles._

-title: 'Introducing Astro: Ship Less JavaScript'
-description: "We're excited to announce Astro as a new way to build static websites and deliver lightning-fast performance without sacrificing a modern developer experience."
-publishDate: 'Tuesday, June 8 2021'
-author: 'fred'
-heroImage: '/social.jpg'
-alt: 'Astro'
-layout: '../../layouts/BlogPost.astro'
---
-
-There's a simple secret to building a faster website — _just ship less_.
-
-Unfortunately, modern web development has been trending in the opposite direction—towards _more._ More JavaScript, more features, more moving parts, and ultimately more complexity needed to keep it all running smoothly.
-
-Today I'm excited to publicly share Astro: a new kind of static site builder that delivers lightning-fast performance with a modern developer experience. To design Astro, we borrowed the best parts of our favorite tools and then added a few innovations of our own, including:
-
- **Bring Your Own Framework (BYOF):** Build your site using React, Svelte, Vue, Preact, web components, or just plain ol' HTML + JavaScript.
- **100% Static HTML, No JS:** Astro renders your entire page to static HTML, removing all JavaScript from your final build by default.
- **On-Demand Components:** Need some JS? Astro can automatically hydrate interactive components when they become visible on the page. If the user never sees it, they never load it.
- **Fully-Featured:** Astro supports TypeScript, Scoped CSS, CSS Modules, Sass, Tailwind, Markdown, MDX, and any of your favorite npm packages.
- **SEO Enabled:** Automatic sitemaps, RSS feeds, pagination and collections take the pain out of SEO and syndication.
-
-This post marks the first public beta release of Astro. **Missing features and bugs are still to be expected at this early stage.** There are still some months to go before an official 1.0 release, but there are already several fast sites built with Astro in production today. We would love your early feedback as we move towards a v1.0 release later this year.
-
-> To learn more about Astro and start building your first site, check out [the project README.](https://github.com/snowpackjs/astro#-guides).
-
-## Getting Started
-
-Starting a new project in Astro is easy:
-
-```shell
-# create your project
-mkdir new-project-directory
-cd new-project-directory
-npm init astro
-
-# install your dependencies
-npm install
-
-# start the dev server and open your browser
-npm run dev
-```
-
-> To learn more about Astro and start building your first site, check out [the project README.](https://github.com/snowpackjs/astro#-guides).
-
-## How Astro Works
-
-Astro works a lot like a static site generator. If you have ever used Eleventy, Hugo, or Jekyll (or even a server-side web framework like Rails, Laravel, or Django) then you should feel right at home with Astro.
-
-In Astro, you compose your website using UI components from your favorite JavaScript web framework (React, Svelte, Vue, etc). Astro renders your entire site to static HTML during the build. The result is a fully static website with all JavaScript removed from the final page. No monolithic JavaScript application required, just static HTML that loads as fast as possible in the browser regardless of how many UI components you used to generate it.
-
-Of course, sometimes client-side JavaScript is inevitable. Image carousels, shopping carts, and auto-complete search bars are just a few examples of things that require some JavaScript to run in the browser. This is where Astro really shines: When a component needs some JavaScript, Astro only loads that one component (and any dependencies). The rest of your site continues to exist as static, lightweight HTML.
-
-In other full-stack web frameworks this level of per-component optimization would be impossible without loading the entire page in JavaScript, delaying interactivity. In Astro, this kind of [partial hydration](https://addyosmani.com/blog/rehydration/) is built into the tool itself.
-
-You can even [automatically defer components](https://codepen.io/jonneal/full/ZELvMvw) to only load once they become visible on the page with the `client:visible` directive.
-
-This new approach to web architecture is called [islands architecture](https://jasonformat.com/islands-architecture/). We didn't coin the term, but Astro may have perfected the technique. We are confident that an HTML-first, JavaScript-only-as-needed approach is the best solution for the majority of content-based websites.

-## Embracing the Pit of Success
-
-> A well-designed system makes it easy to do the right things and annoying (but not impossible) to do the wrong things<div class="source"><p>– Jeff Atwood</p>[Falling Into The Pit of Success](https://blog.codinghorror.com/falling-into-the-pit-of-success/)</div>
-
-Poor performance is often framed as a failure of the developer, but we respectfully disagree. In many cases, poor performance is a failure of tooling. It should be difficult to build a slow website.
-
-Astro's main design principle is to lead developers into what [Rico Mariani](https://twitter.com/ricomariani) dubbed "the pit of success". It is our goal to build every site "fast by default" while also delivering a familiar, modern developer experience.
-
-By building your site to static HTML by default, Astro makes it difficult (but never impossible 😉) to build a slow site.
-
-## Long-Term Sustainability
-
-Astro is built by the team of open source developers behind [Snowpack](https://snowpack.dev) and [Skypack](https://skypack.dev), with additional contributions from the community.
-
-**Astro is and always will be free.** It is an open source project released under the [MIT license](https://github.com/snowpackjs/astro/blob/main/LICENSE).
-
-We care deeply about building a more sustainable future for open source software. At the same time, we need to support Astro's development long-term. This requires money (donations alone aren't enough.)
-
-We're inspired by the early success of projects like [Tailwind](https://tailwindcss.com/), [Rome](https://rome.tools/), [Remix](https://remix.run/), [Ionic](https://ionicframework.com/), and others who are experimenting with long-term financial sustainability on top of Open Source. Over the next year we'll be exploring how we can create a sustainable business to support a 100% free, open source Astro for years to come.
-
-If your company is as excited about Astro as we are, [we'd love to hear from you.](https://astro.build/chat)
-
-Finally, I'd like to give a **HUGE** thanks to the 300+ developers who joined our earliest private beta. Your feedback has been essential in shaping Astro into the tool it is today. If you're interested in getting involved (or just following along with development) please [join us on Discord.](https://astro.build/chat)
