Package Exports

dot-json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dot-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

    }
}

dot-json myfile.json user.name

Quick tip for editing package.json

Add to .bash_profile:

alias package="dot-json package.json"

Use it like this:

package name "my-package"

Use it in NodeJS

Initialization

var DotJson = require('dot-json');
var myfile = new DotJson('myfile.json');

Writing

asynchronous

myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save(function(){
  console.log('saved');
});

synchronous

myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save();

myfile.json now looks like

{
    "user": {
        "name": "John Doe",
        "email": "john@example.com"
    }
}

Reading

asynchronous

myfile.get('user.name', function(value){
  // value = 'John Doe'
  console.log(value);
});

synchronous

var value = myfile.get('user.name');
// value = 'John Doe'
console.log(value);

Deleting

asynchronous

myfile.delete('user.name').save(function(){
  console.log('saved');
});

synchronous

myfile.delete('user.name').save();

myfile.json now looks like

{
    "user": {
        "email": "john@example.com"
    }
}
