minify-html-wasm

library0.1.1jsnpmunverified

WASM wrapper around the Rust crate minify-html, providing extremely fast HTML + JS + CSS minification. Version 0.1.1 is stable. It leverages WebAssembly for near-native performance and offers a comprehensive set of minification options. Unlike JavaScript-based minifiers, this package runs the Rust minify-html library in the browser or Node.js via WASM, delivering high speed and consistency across environments.

Code

Verified usage

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

init

✓ import init, { minify } from 'minify-html-wasm'

✗ const init = require('minify-html-wasm')

ESM-only package; defaults to WebAssembly initialization function.

minify

✓ import { minify } from 'minify-html-wasm'

✗ const minify = require('minify-html-wasm').minify

Named export; must be used after await init().

MinifyOptions

✓ import type { MinifyOptions } from 'minify-html-wasm'

✗ import { MinifyOptions } from 'minify-html-wasm'

TypeScript type, not a runtime value.

Initialize the WASM module and minify an HTML string with options.

import init, { minify } from 'minify-html-wasm'; const encoder = new TextEncoder(); const decoder = new TextDecoder(); await init(); const input = '<p> Hello, world! </p>'; const minified = decoder.decode( minify(encoder.encode(input), { keep_spaces_between_attributes: true, keep_comments: true, }) ); console.log(minified);

Debug

Known issues

gotchainit() must be called before any minify() call; otherwise panic occurs.

fix

Ensure await init() is executed before using minify().

affects: >=0.0.1

breakingInput and output are Uint8Array, not strings; requires TextEncoder/TextDecoder.

fix

Encode strings with TextEncoder and decode with TextDecoder.

affects: >=0.1.0

deprecatedThe web/wasm path for init() URL is changing; future versions may not support CDN loading without bundler.

fix

Use default init() without URL for Node.js; for browser, bundle the WASM file.

affects: >=0.1.0

gotchaOptions object is required; passing undefined or incomplete options may cause unexpected behavior.

fix

Always provide a complete MinifyOptions object (all fields optional but object must exist).

affects: >=0.0.1

gotchaVery large HTML can cause WASM memory errors; no streaming support.

fix

Split large documents into chunks or use a streaming minifier.

affects: >=0.0.1

Errors

Common errors & fixes

Error: WebAssembly.instantiate(): expected magic word

init() called with an incorrect URL or the WASM binary is not loaded properly.

fix

Provide a valid URL to the WASM file or use default init() which expects the WASM to be in the same directory.

TypeError: minify is not a function

imported minify incorrectly (e.g., default import) or init not awaited.

fix

Use named import: import { minify } from 'minify-html-wasm' and ensure init() completes.

Error: Expected a Uint8Array

Passed a string instead of Uint8Array to minify.

fix

Encode strings with TextEncoder before passing: const input = new TextEncoder().encode(htmlString);
