🗻 AstroBiome

This Astro integration brings Biome tools your Astro project.

Biome

Note

AstroBiome will not lint / format 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 AstroBiome, run the following from your project directory and follow the prompts:

Using NPM:

npx astro add astro-biome

Using Yarn:

yarn astro add astro-biome

Using PNPM:

pnpx astro add astro-biome

Install dependencies manually

First, install the AstroBiome integration like so:

npm install -D -E astro-biome

Then, apply this integration to your astro.config.* file using the integrations property:

astro.config.ts

import Biome from "astro-biome";

export default { integrations: [Biome()] };

Getting started

The utility will now lint and format with Biome all of your JavaScript and TypeScript files, including CommonJS modules in the Astro outDir folder.

You can override any of the default options from the configurations of:

• biome

or disable them entirely:

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Biome: false,
		}),
	],
};

Note

If you provide a biome.json config file the utility will pick it up automatically.

[!WARNING]

The configuration options from the astro.config.ts file will override the biome.json config.

Add Multiple Paths

You can add multiple paths to validate / format by specifying an array as the Path variable.

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Path: ["./Target", "./Build"],
		}),
	],
};

Input-Output Mapping

You can also provide a map of paths for different input output directories:

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Path: new Map([["./Source", "./Target"]]),
		}),
	],
};

Or an array of the two:

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Path: [
				// Format Target
				"./Target",
				// Format Target one more time into a different directory
				new Map([["./Target", "./TargetInline"]]),
			],
		}),
	],
};

File Filtering

You can provide a filter to exclude files from formatting. A filter can be an array of regexes or a single match. You can use functions, as well to match on file names:

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Exclude: [
				"Firebase.ts",
				(File: string) => File === "./Source/Library/File.ts",
			],
		}),
	],
};

Controlling Logging

Set Logger to 0 if you do not want to see debug messages. Default is 2:

astro.config.ts

import Biome from "astro-biome";

export default {
	integrations: [
		Biome({
			Logger: 0,
		}),
	],
};
