snowpack-plugin-optimize

library0.5.0jsnpmunverified

A Snowpack plugin that minifies JS (via terser), CSS (via csso), and HTML (via html-minifier) for production builds. Supports source map generation/remapping, optional modulepreload injection, and TypeScript declaration files. Version 0.5.0 (last release June 2020) works with Snowpack ^2.17.1 and is in maintenance mode, as Snowpack has since been deprecated in favor of Vite. It does not bundle; for bundling the official webpack plugin is recommended.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin

✓ plugins: [['snowpack-plugin-optimize', options]]

✗ plugins: [require('snowpack-plugin-optimize')]

Always use the plugin reference as a string in the array syntax; direct require may not be resolved correctly by Snowpack.

Snowpack config enabling minification for JS, CSS, and HTML with source maps and modulepreload.

// snowpack.config.js module.exports = { plugins: [ [ 'snowpack-plugin-optimize', { minifyJs: true, minifyCss: true, minifyHtml: true, jsOptions: { sourceMap: true, compress: { ecma: 2019 }, format: { ecma: 2019 } }, cssOptions: { sourceMap: true }, htmlOptions: { collapseWhitespace: true, keepClosingSlash: true, removeComments: true }, modulePreload: true } ] ] }

Debug

Known issues

gotchaSnowpack 3+ removed support for plugin string shorthand – you must use the array syntax [name, options].

fix

Ensure your config uses the array form: ['snowpack-plugin-optimize', opt]

affects: >=0.5.0

deprecatedSnowpack itself is deprecated in favor of Vite. This plugin will not receive updates for newer build tools.

fix

Migrate to Vite and use vite-plugin-optimize or similar.

affects: >=0.0.0

gotchaThe plugin silently ignores options if the plugin string is not placed in an array; common mistake with nested configs.

fix

Always wrap options in an array: ['snowpack-plugin-optimize', { ... }]

affects: >=0.5.0
