library1.0.0jsnpmunverified

A minimal Node.js wrapper around the Less CSS preprocessor, allowing compilation of .less files to CSS programmatically and via command-line. Version 1.0.0 is the initial release with basic compilation support. No longer maintained; users should switch to the official 'less' npm package which is actively developed and includes all features.

Verified usage

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

node-less
✓ import less from 'node-less'
✗ const less = require('node-less')
This package is deprecated; use 'less' package instead. ESM import shown for clarity.
less.compile
✓ import less from 'node-less'; const css = less.compile('.class { color: red; }')
✗ const { compile } = require('node-less'); compile('.class { color: red; }')
The API is synchronous; no promise or callback needed.
less.render
✓ import less from 'node-less'; less.render('.a { .b { color: red; } }')
✗ less.renderFile('style.less', callback)
render() expects string input, not file path. For file compilation, use CLI or migrate to 'less' package.

Shows basic usage of less.compile() to process Less source and produce CSS output synchronously.

import less from 'node-less'; const input = ` @base: #f938ab; .box { color: @base; border-color: darken(@base, 10%); } `; try { const output = less.compile(input); console.log(output); } catch (err) { console.error('Compilation error:', err); }
