Blowson can either be used as a parsing function in your Node script or as a CLI tool.

Add package to Node project

$ npm i blowson --save

Create a sample file "data.js"

Your sample data file:

const userCount = 50;
const commentCount = 250;
​
module.exports = {
    "users": [
        { "id": 1, "firstname": "Mike", "age": 12 },
        { "id": userCount, "firstname": "Lucy", "age": 31 }
    ],
    "comments": [
        { "id": 1, "user_id": 1, "text": "Some text" },
        { "id": commentCount, "user_id": userCount, "text": "Some more text" }
    ]
};

Parse sample data in Node script

And than in your script:

const blowson = require('blowson');
const data = require('./data.js');
​
const extendedData = blowson(data);
​
console.log(extendedData);

The blowson function accepts either a JSON string or a JSON like JavaScript object. In case of a JSON string, a nicelly formatted string is being returned. This however involves some extra parsing on the side of Blowson, so we recommend using a JSON like JS object.

Have a look at the index.js for a complete example and check out data.js for an example data file.

CLI Usage

You can use Blowson as a CLI script. All you need to do is install the package globally:

$ npm install -g blowson

And than run it like this:

$ blowson data.js data-extended.js

Or:

$ blowson data.json data-extended.json
