Allows for very simple JSON file updating in one line

Package Exports

  • json-update

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 (json-update) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

This is a simple way to update (or load) a JSON file. If the JSON file does not exist it will be created (along with a directory structure if those directories don't exist yet).

Uses lodash to merge existing JSON data with the object you specify, merging anything with an existing property and adding properties if they are new. See lo-dash merge docs for a detailed explanation of the merging process, but basically simple properties like strings or numbers are replaced, and objects/arrays have the values or key/values added into the array/object.

npm install json-update

Updating a JSON file (and return the new object):

json = require('json-update')

json.update('data.json', { test: 'value x' }, function(err, obj) {
  if (typeof err !== "undefined" && err !== null) {
    console.log("Error updating json: " + err.message);
  }
  console.log(obj);
)};

Loading a JSON file (note that in the case of loading a valid JSON file must already exist):

json = require('json-update')

json.load('data.json', function(err, obj) {
  console.log("Loaded from json:");
  console.log(obj);
});
