A library for colorizing JSON strings

This package is a simple console syntax highlighter for JSON.

npm install --save json-colorizer

const { colorize } = require('json-colorizer');
console.log(colorize({ "foo": "bar" }));

You can also pass a JavaScript object to the colorize function:

const { colorize } = require('json-colorizer');
console.log(colorize({
  foo: 'bar',
  baz: 42
}));

By default, the output JSON will be pretty-printed with an indentation of 2 spaces. You can adjust this by passing the indent option.

const { colorize } = require('json-colorizer');
console.log(colorize({
  foo: 'bar',
  baz: 42
}, { indent: 4 }));

You can override any of the colors used for token types by providing a colors option. This should map token types to the names of color functions. These color functions are contained in the color object exported by the library.

const { colorize, color } = require('json-colorizer');

console.log(colorize({ foo: 'bar' }, {
  colors: {
    StringLiteral: color.red
  }
}));

The list of valid token types and color functions are listed below.

• Brace: curly braces ({, })
• Bracket: square brackets ([, ])
• Colon: colon character (:)
• Comma: comma character (,)
