express-minify

library1.0.0jsnpmunverified

Express middleware that automatically minifies and caches JavaScript, CSS, and JSON responses. Supports compiling LESS/SASS/Stylus/CoffeeScript before minifying. Version 1.0.0 is stable, with a long history but recent releases are infrequent. Key differentiators: automatic content-type detection, in-memory or disk caching, and per-response control. Unlike other minification middlewares, it does not require specifying a source directory and can work alongside express.static and compression.

Code

Verified usage

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

default

✓ import minify from 'express-minify'

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

The package exports a function that creates the middleware. CJS require works too, but ESM import is recommended for modern apps.

Shows basic setup with express, compression, static files, and minify middleware. Cache is disabled for demonstration.

import express from 'express'; import compression from 'compression'; import minify from 'express-minify'; const app = express(); app.use(compression()); app.use(minify({ cache: false })); app.use(express.static('public')); app.listen(3000);

Debug

Known issues

gotchaCache directory must be writable if cache option is a string path.

fix

Ensure the directory exists and is writable by the Node process, or use in-memory cache (cache: false).

affects: >=1.0.0

gotchaMiddleware order matters: compression should be before minify if you want to GZip the minified output.

fix

Place compression() before minify() in the middleware stack.

affects: >=1.0.0

deprecatedThe jsonMatch option exists but JSON minification is not recommended as it may break JSON if whitespace is significant.

fix

Set jsonMatch: false to disable JSON minification.

affects: >=1.0.0

Errors

Common errors & fixes

Error: EACCES: permission denied, mkdir '/path/to/cache'

Cache directory is not writable.

fix

Use a writable directory or disable cache: app.use(minify({ cache: false }));

TypeError: minify is not a function

Using default import when package is CJS and requires .default.

fix

Use const minify = require('express-minify').default; or switch to ESM import minify from 'express-minify';
