Json Change

Description

Json Change is a JavaScript Module to replace Placeholders in an JSON Array or Object with Arguments, which can be defined.

Getting Started

npm install --save @lorenzmueksch/json-change

Insert this line in you app.js:

const change = require('@lorenzmueksch/json-change');

Usage

change(options);

The Properties of the options are:

• args: The values which will be put in the json
• json: The Json Object or Array you want to change
• fileUri: You can also enter a file Uri if you want to let json-change read the JSON file

The Arguments can be set like this:

[{
    "<name of the key>": "<value, which will be injected>"
}]

Define the placeholders in the JSON like this:

${<Name of the key, which will be replaced>}

For Example:

The JSON looks like this:

changeJSON = [
    { msg: "Hello ${username}"},
    { age: "Your Age is ${age}"
];

With Object

The Function to replace the placeholders with your arguments is:

change({ json: changeJSON, args: [{ username: 'LorenzMueksch' }, { age: '18' }]});

The Function will return

[
    { msg: "Hello LorenzMueksch" },
    { age: "Your Age is 18" }
]

With File

This Option will return a JSON Object. It will not write the changes to a file

So if you want to let json-change read your file you can simply set the fileUri in the options Object:

change({ fileUri: 'path to your file', args: [{ username: 'LorenzMueksch' }, { age: '18' }] });
