EasyJSON

With EasyJSON you can simply invoke the exported function to manipulate JSON file. At first, passing a path to path function to choose a JSON file. And EasyJSON support the chain call.

Example app.js:

var easyjson = require('easyjson');
 
// it should output your JSON file
easyjson.path('test')
    .express();

You can also add, modify or delete a item with your JSON file. And EasyJSON support chained invoke.

var easyjson = require('easyjson');
 
easyjson.path('test')
    .add('license', 'MIT')
    .express()
    .add('blog', 'http://tinple.me')  
    .express()
    .del('version')
    .express()
    .modify('project', 'EasyJSON')
    .express();

easyjson can get the value of your item with JSON file. Just call get(key) to get it.

var easyjson = require('easyjson'),
  author = easyjson.path('test').get('author'),
  email = easyjson.path('test').get('email');

Most Useful(support nested data)

Actually, EasyJSON support nested data, that means you can manipulate your JSON file most effectivly.

var easyjson = require('easyjson').path('test');
 
/**
 * "author": {
 *      "name": "Tinple"
 * }
 * ==>
 * "author": {
 *      "name": "Tinple",
 *    "friend": {
 *      "name": "Kristine"
 *    }
 *  }
 */
easyjson.add('author[friend][name]', 'Kristine');
 
/**
 * push 'path.json' to existed array files
 * "files": ["index.js"]
 * ==>
 * "files": ["index.js", "path.json"]
 */
easyjson.add('files', 'path.json');
 
// it will delete whole friend object, the same as array
easyjson.del('author[friend]');
 
// modify the array, only index support
easyjson.modify('files[1]', 'path2.json');
 
// modify the obj key
easyjson.modify('author[friend][name]', 'Panda');
 
/** More complex
 * "author": {
 *      "name": "Tinple"
 * }
 * ==>
 * "author": {
 *      "name": "Tinple",
 *    "friend": [{
 *      "name": "Kristine"
 *    }]
 *  }
 */
easyjson.add('author[friend][0][name]', 'Kristine');

Warning

EasyJSON will do nothing when you pass a nonexistent key to modify() and del(). As for add(key, value), EasyJSON will judge whether the key exists firstly. If not, it will added normally.

If it has already existed, there are two situations that the key should be treated.

  1. The key is an array, then the value will be pushed.
  2. The key is other type, like Object or String, then EasyJSON do nothing.
