astro-compress 🗜️

This Astro integration brings compression utilities to your Astro project.

CSS HTML JavaScript Images SVG

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 astro-compress, run the following from your project directory and follow the prompts:

# Using NPM
npx astro add astro-compress
# Using Yarn
yarn astro add astro-compress
# Using PNPM
pnpx astro add astro-compress

Install dependencies manually

First, install the astro-compress integration like so:

npm install -D -E astro-compress

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

astro.config.ts

import type { AstroUserConfig } from "astro";
import compress from "astro-compress";

export default (): AstroUserConfig => ({ integrations: [compress()] });

Getting started

The utility should now automatically compress all your CSS, HTML and JavaScript files in the dist folder.

The following image file types will also be compressed.

• avci
• avcs
• avif
• avifs
• gif
• heic
• heics
• heif
• heifs
• jfif
• jif
• jpe
• jpeg
• jpg
• png
• raw
• tiff
• webp

SVG compression is supported, as well via svgo.

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

• csso
• html-minifier-terser
• terser
• sharp
• svgo

or disable them entirely:

import type { AstroUserConfig } from "astro";
import compress from "astro-compress";

export default (): AstroUserConfig => ({
	integrations: [
		compress({
			css: false,
			html: false,
			js: false,
			img: false,
			svg: false,
		}),
	],
});

If your path is different than dist be sure to update it accordingly:

import type { AstroUserConfig } from "astro";
import compress from "astro-compress";

export default (): AstroUserConfig => ({
	outDir: "./build",
	integrations: [
		compress({
			path: "./build",
		}),
	],
});

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

import type { AstroUserConfig } from "astro";
import compress from "astro-compress";

export default (): AstroUserConfig => ({
	integrations: [
		compress({
			logger: 0,
		}),
	],
});
