1.1.1 • Public • Published

rfc6902 simple diff generator

An extremely simple JSON patch tool that generates rfc6902 compliant add, remove, and replace operations only.

If you are looking for a complete implementation(differ and patcher), please check @chbrown's rfc6902 or Cujo.js's jiff.

Getting started

npm install rfc6902-simple-diff
 
var simpleDiff = require('rfc6902-simple-diff');
 
var lhs = {
    foo: "bar",
    baz: { bar: "foo" },
    qux: ["foo", "bar"]
};
 
var rhs = {
    foo: "baz",
    baz: { qux: "bar" },
    qux: ["foo","baz", "biz"]
};
 
console.log(simpleDiff(lhs, rhs));
 
 
// Outputs:
[
    { op: 'replace', path: '/foo', value: 'baz' },
    { op: 'remove', path: '/baz/bar' },
    { op: 'add', path: '/baz/qux', value: 'bar' },
    { op: 'replace', path: '/qux/1', value: 'baz' },
    { op: 'add', path: '/qux/-', value: 'biz' }
]

Customizing output

You can call the diff function with optional options object to customize output.

 
console.log(simpleDiff(lhs, rhs, {path: 'bub'}));
 
 
// Outputs:
[
    { op: 'replace', path: '/bub/foo', value: 'baz' },
    { op: 'remove', path: '/bub/baz/bar' },
    { op: 'add', path: '/bub/baz/qux', value: 'bar' },
    { op: 'replace', path: '/bub/qux/1', value: 'baz' },
    { op: 'add', path: '/bub/qux/2', value: 'biz' }
]
 
console.log(simpleDiff(lhs, rhs, {append: false}))
 
// Outputs:
[
    { op: 'replace', path: '/foo', value: 'baz' },
    { op: 'remove', path: '/baz/bar' },
    { op: 'add', path: '/baz/qux', value: 'bar' },
    { op: 'replace', path: '/qux/1', value: 'baz' },
    { op: 'add', path: '/qux/2', value: 'biz' }
]
