library1.0.2jsnpmunverified

A Nunjucks add-on (v1.0.2, latest) that passes template source through html-minifier before rendering. It wraps Nunjucks' built-in loaders (e.g., FileSystemLoader) to minify HTML output automatically. Different from standalone minification by integrating directly into the template loading pipeline. No active updates since initial release.

Verified usage

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

FileMinifyLoader
✓ import { FileMinifyLoader } from 'nunjucks-minify-loaders'
✗ const { FileMinifyLoader } = require('nunjucks-minify-loaders')
Package exports only this class; named import required.
FileMinifyLoader
✓ const { FileMinifyLoader } = require('nunjucks-minify-loaders')
✗ const FileMinifyLoader = require('nunjucks-minify-loaders')
Correct CommonJS usage destructures the named export.
default
✓ import nunjucksMinifyLoaders from 'nunjucks-minify-loaders'
✗ import { default } from 'nunjucks-minify-loaders'
Default import not available; use named import.

Shows how to create a Nunjucks environment with a FileMinifyLoader that minifies templates using html-minifier options.

const nunjucks = require('nunjucks'); const { FileMinifyLoader } = require('nunjucks-minify-loaders'); const opts = { watch: true, noCache: false, minify: { removeComments: true, minifyJS: true, } }; const loader = new FileMinifyLoader('./views', opts); const env = new nunjucks.Environment(loader); // Templates from ./views will be minified const html = env.render('page.html', { title: 'Hello' }); console.log(html);
Debug
Known issues
gotchaThe library only supports FileSystemLoader from Nunjucks. Other loaders (e.g., WebLoader) are not wrapped.
fix
If you need other loaders, extend the class or use a different minification approach.
affects: >=1.0.0
gotchaThe html-minifier options must be passed in the 'minify' object; incorrect nesting will be silently ignored.
fix
Ensure options are under 'minify' key, e.g., { minify: { removeComments: true } }.
affects: >=1.0.0
gotchaThe package has no TypeScript type definitions; type safety is not provided.
fix
Use @types/nunjucks and define your own types or use plain JavaScript.
affects: >=1.0.0
Errors
Common errors & fixes
TypeError: FileMinifyLoader is not a constructor
Using default import instead of named import.
fix
Use const { FileMinifyLoader } = require('nunjucks-minify-loaders');
Error: Cannot find module 'html-minifier'
Missing required peer dependency html-minifier.
fix
Run npm install html-minifier --save
TypeError: loader.getSource is not a function
Passing an invalid loader class or options without a valid 'minify' object.
fix
Ensure first argument is a valid Nunjucks loader path or a loader instance, and options contain minify configuration.
