## JSON-Patch
|
||||
|
||||
Provides the ability to modify and test a JSON according to a
|
||||
[RFC6902 JSON patch](http://tools.ietf.org/html/rfc6902) and [RFC7396 JSON Merge Patch](https://tools.ietf.org/html/rfc7396).
|
||||
|
||||
*Version*: **1.0**
|
||||
|
||||
[](http://godoc.org/github.com/evanphx/json-patch)
|
||||
|
||||
[](https://travis-ci.org/evanphx/json-patch)
|
||||
|
||||
### API Usage
|
||||
|
||||
* Given a `[]byte`, obtain a Patch object
|
||||
|
||||
`obj, err := jsonpatch.DecodePatch(patch)`
|
||||
|
||||
* Apply the patch and get a new document back
|
||||
|
||||
`out, err := obj.Apply(doc)`
|
||||
|
||||
* Create a JSON Merge Patch document based on two json documents (a to b):
|
||||
|
||||
`mergeDoc, err := jsonpatch.CreateMergePatch(a, b)`
|
||||
|
||||
* Bonus API: compare documents for structural equality
|
||||
|
||||
`jsonpatch.Equal(doca, docb)`
