minify-html-ssr

For SSR WASM import.

What it does

This library removes extraneous whitespaces between HTML tags. Single spaces are preserved where necessary.

Directions

Local

1. wasm-pack build --target=nodejs --out-dir path-to-node-project
2. import and add const { minify_html } = require('../utils/minify-html/html_whitespace'); to your render pipeline.

res.send(minify_html(body));

npm package

1. npm install minify-html-ssr
2. Minify the html body before sent down.

Downsides

• This is a runtime library. It is meant to work fast for you. However, a build time solution that collapses whitespace might be better for your app.

• Do you brotli compress your HTML? If not, you might be able to drop ~30% of your characters versus gzip.
