jwccminify

A lightweight JSON minifier that removes whitespace and comments from JWCC (JSON with Commas and Comments) or HuJSON (Human JSON).

• Removes single-line comments (//)
• Removes multi-line comments (/* */)
• Removes whitespace (" \t\r\n")
• Removes trailing commas before closing brackets and braces
• No RegExp.
• Zero dependencies.
• Fault-tolerant: Invalid JSON is also parsable.

Usage

npm install jwccminify

ESM / CommonJS

import jwccminify from 'jwccminify';
// or
import { jwccminify } from 'jwccminify';
// or
const { jwccminify } = require('jwccminify');

const input = `{
  "name": "example", // This is a comment
  "value": 123, /* Multi-line
     comment */
}`;

const output = jwccminify(input);
console.log(output); // {"name":"example","value":123}

import { jwccstrip } from 'jwccminify';
// or
const { jwccstrip } = require('jwccminify');

const input = `{
  "name": "example", // This is a comment
  "value": 123, /* Multi-line
     comment */

const output = jwccstrip(input);
