deno-colorize-json

A library for colorizing JSON strings for DENO

Adapted from the Node Version json-colorizer

Usage and Installation

Installation

dpm install json-colorizer

Or import like:

import { colorize } from 'https://deno.land/x/json_colorizer/mod.ts';

Usage

import { colorize } from 'https://deno.land/x/json_colorizer/mod.ts';
colorize('{ \'foo\': \'bar\' }');

If you pass a string to the colorize function, it will treat it as pre-serialized JSON. This can be used in order to colorize pretty-printed JSON:

import { colorize } from 'https://deno.land/x/json_colorizer/mod.ts';
const json = JSON.stringify({ 'foo': 'bar' }, null, 2);
colorize(json);

And you can save the content in a variable and not print with this:

import { colorize } from 'https://deno.land/x/json_colorizer/mod.ts';

const msg = colorize('{ \'fooo\': \'baaar\' }', { print: false });

console.log(`Save in a variable ${msg}`);

  • BRACE
  • BRACKET
  • COLON
  • COMMA

  • STRING_LITERAL

You can custom like:

  colorize,
} from 'https://deno.land/x/json_colorizer/mod.ts';

const example = {
  aaaaaa: 'eeeee',
  aaa: 2,
  a: {
    e: 'xd',
  },
};
