express-beautifier

library0.1.4jsnpmunverified

Express.js middleware that beautifies or minifies HTML, JS, and CSS output from any template engine. Current stable version is 0.1.4 (last released in 2022). It wraps js-beautify and html-minifier to provide human-readable output in development and minified output in production. Intended as a maintained fork of the unmaintained express-beautify package. It supports custom options for both beautification and minification, and provides helper methods like res.sendHTML, res.sendJS, res.sendCSS.

Verified usage

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

default

✓ import expressBeautify from 'express-beautify'

✗ const expressBeautify = require('express-beautify')

Since v0.1.0, package uses default export. CommonJS require works but TypeScript ESM import is recommended.

minify

✓ import { minify } from 'express-beautify'

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

Named export for minify middleware. In CJS, destructure from require.

expressBeautify (with options)

✓ import createBeautifier from 'express-beautify'; const expressBeautify = createBeautifier({indent_size: 4})

✗ const expressBeautify = new (require('express-beautify'))({indent_size: 4})

The default export is a factory function that accepts options and returns middleware.

Demonstrates importing express-beautify, creating beautify middleware with options, using res.sendHTML, and setting up minify middleware.

import express from 'express'; import createBeautifier from 'express-beautify'; const app = express(); // Use beautify middleware const beautify = createBeautifier({ indent_size: 2 }); app.use(beautify); app.get('/', (req, res) => { res.sendHTML('<div>Hello <span>World</span></div>'); }); // For minify in production import { minify } from 'express-beautify'; const min = minify({ collapseWhitespace: true }); app.use(min); app.listen(3000);

Debug

Known issues

breakingPackage renamed from express-beautify to express-beautifier; imports changed accordingly.

fix

Replace all instances of 'express-beautify' with 'express-beautifier' in import statements.

affects: >=0.1.0

deprecatedres.sendHTML, res.sendJS, res.sendCSS are non-standard Express methods added by this middleware; they may conflict with other middleware.

fix

Use standard res.send or res.render instead, or manually handle formatting.

affects: >=0.1.0

gotchaThe middleware must be used BEFORE routes that send HTML/JS/CSS; otherwise it will not process the output.

fix

Ensure app.use(beautify) is placed before route definitions.

affects: >=0.1.0

gotchaMinify and beautify cannot be used simultaneously; using both will cause unpredictable results.

fix

Use only one of the two middleware in a given request chain. Typically beautify for dev, minify for prod.

affects: >=0.1.0

deprecatedThe package is based on an unmaintained fork; updates to js-beautify or html-minifier may not be reflected.

fix

Consider using js-beautify and html-minifier directly in your own middleware for more control.

affects: >=0.1.0

gotchaOptions passed to factory are global; cannot change per-request.

fix

Create separate middleware instances for different routes if different options are needed.

affects: >=0.1.0

Errors

Common errors & fixes

Cannot find module 'express-beautify'

Installing express-beautifier but importing as express-beautify

fix

Change import to 'express-beautifier' or vice versa.

Misunderstanding default export; trying to use require('express-beautify') as a constructor

fix

Use `const expressBeautify = require('express-beautify');` and then call `expressBeautify({...})`.

TypeError: res.sendHTML is not a function

Middleware not applied before route handler

fix

Place `app.use(beautify)` before the route definition.
