# [Inline] 🦔
This **[Astro integration][astro-integration]** brings [`beasties`][beasties] to
your Astro project.
Beasties is a plugin that inlines your app's [critical CSS] and lazy-loads the
rest.
> **Note**
>
> `Inline` will not inline your requests, only your statically generated build
> and pre-rendered routes.
## Installation 🚀
There are two ways to add integrations to your project. Let's try the most
convenient option first!
### `astro add` command
Astro includes a CLI tool for adding first party integrations: `astro add`. This
command will:
1. (Optionally) Install all necessary dependencies and peer dependencies
2. (Also optionally) Update your `astro.config.*` file to apply this integration
To install `Inline`, run the following from your project directory and follow
the prompts:
Using NPM:
```sh
npx astro add @playform/inline
```
Using Yarn:
```sh
yarn astro add @playform/inline
```
Using PNPM:
```sh
pnpx astro add @playform/inline
```
### Install dependencies manually
First, install the `Inline` integration like so:
```sh
npm install -D -E @playform/inline
```
Then, apply this integration to your `astro.config.*` file using the
`integrations` property:
```ts
export default {
integrations: [(await import("@playform/inline")).default()],
};
```
## Getting started
Beasties will now automatically inline the critical CSS of your HTML files.
### Default Inlining
You can override any of the default options from the configuration of:
- [`beasties`](HTTPS://github.com/DanielRoe/Beasties#usage)
or disable them entirely:
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Beasties: false,
}),
],
};
```
### Add Multiple Paths
You can add multiple paths to inline by specifying an array as the `Path`
variable.
**`astro.config.ts`**
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Path: ["./Target", "./Build"],
}),
],
};
```
### Input-Output Mapping
You can also provide a map of paths for different input output directories.
**`astro.config.ts`**
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Path: new Map([["./Source", "./Target"]]),
}),
],
};
```
Or an array of the two.
**`astro.config.ts`**
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Path: [
// Inline Target
"./Target",
// Inline Target one more time into a different directory
new Map([["./Target", "./TargetInline"]]),
],
}),
],
};
```
### File Filtering
You can filter files to exclude specific ones from inlining. A filter can be an
array of regular expressions or a single match. You can also use functions to
match on file names:
**`astro.config.ts`**
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Exclude: [
"File.html",
(File: string) => File === "./Target/index.html",
],
}),
],
};
```
### Controlling Logging
You can control the logging level by setting the `Logger` parameter. The default
value is `2`, but you can set it to `0` if you don't want to see debug messages:
```ts
export default {
integrations: [
(await import("@playform/inline")).default({
Logger: 0,
}),
],
};
