Provides an express middleware for a JSON store that supports real-time client updates using JSON-patch"
This module is installed via npm:
$ npm install json-patch-api
var jsonPatchApi = require('json-patch-api'); var app = express(); var io = require('socket.io')(server); app.use('/api', require('json-patch-api')(io));
Stores whatever application/json payload you send it and replaces the current document and returns JSON-PATCH commands that are needed to update the document.
Returns the current JSON document stored at the api endpoint. And a header
X-Last-Patched with the epoch time at which the last patch was applied.
Returns a JSON struct which represents a sequence of JSON-PATCH operations which, if repeated sequentially would yield the current state of the document given a snapshot from time TIMESTAMP.
With a JSON-Patch payload will apply the patch to the current endpoint's state and broadcast it to all listening clients.
