node-tosource

Actions Status npm version codecov

toSource is a super simple function that converts JavaScript objects back to source code.

Introduction

Motivation: JSON doesn't support serializing functions, dates, or regular expressions. I wanted a quick and simple way to push trusted data structures with code from Node down to the browser.

This should make it easier to share code and modules between the server and client.

Installation

npm install tosource

Examples

The following code:

import toSource from 'tosource';

console.log(
  toSource([
    4,
    5,
    6,
    'hello',
    {
      a: 2,
      b: 3,
      '1': 4,
      if: 5,
      yes: true,
      no: false,
      nan: NaN,
      infinity: Infinity,
      undefined: undefined,
      null: null,
      foo: function (bar) {
        console.log('woo! a is ' + a);
        console.log('and bar is ' + bar);
      },
    },
    /we$/gi,
    new Date('Wed, 09 Aug 1995 00:00:00 GMT'),
  ]),
);

Output:

[ 4,
  5,
  6,
  "hello",
  { 1:4,
    a:2,
    b:3,
    "if":5,
    yes:true,
    no:false,
    nan:NaN,
    infinity:Infinity,
    "undefined":undefined,
    "null":null,
    foo:function (bar) {
        console.log('woo! a is ' + a);
        console.log('and bar is ' + bar);
      } },
  /we$/gi,
  new Date(807926400000) ]
