express-minifier

library1.0.1jsnpmunverified

Express middleware for automatic minification of CSS, JS, and HTML responses. Version 1.0.1, no recent updates. It intercepts res.send, res.sendFile, and express.static to minify content. Compared to alternatives like express-minify or uglify-js-middleware, this package bundles clean-css and html-minifier but has known vulnerabilities and minimal configuration.

Install & Compatibility

No compatibility data collected yet for this library.

Code

Verified usage

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

default

✓ import minify from 'express-minifier'

✗ const minify = require('express-minifier')

Package does not export named commonjs; default export only. ESM import works, but require is common.

express-minifier

✓ const minify = require('express-minifier')

✗ import { minify } from 'express-minifier'

No named export; use default import or require.

Options

✓ const opts = { send: false }

✗ const opts = { minify: false }

Options are plain object properties, not a class.

Demonstrates basic setup with all minification options enabled, including res.send and static file minification.

const express = require('express'); const minify = require('express-minifier'); const app = express(); app.use(minify(app, { send: true, static: true, minifyCSS: true, minifyJS: true, minifyHTML: true })); app.get('/', (req, res) => res.send('<h1>Hello</h1>')); app.listen(3000);
