Proliferate

/pɹəˈlɪf.əɹ.eɪt/ (transitive, intransitive)
To increase in number or spread rapidly; to multiply.

The files proliferated rapidly.

---

Create a bunch of simple files in a jiffy.

Right now it's pretty simple and just makes a bunch of files in a brute force way. In the future I'd like to support more token replacement, and bulk creation of directories in addition to files.

Usage

Install the package via npm: npm i -D proliferate.

const Proliferation = require('proliferate');
const path = require('path');
 
// create a proliferation
const p = new Proliferation({
  count: 5000,
  fileName: 'file-%ID%.json',
  filePath: path.join(__dirname, 'data'),
  content: '{ "id": "%ID%" }'
});
 
// make it rain
p.write(); // write is done asynchronously

Usage

The Proliferation class takes a simple configuration object. Right now it simply replaces the %ID% token where it appears in the file name or content with a numeric ID. The ID is zero indexed, left padded to match the full count.

Proliferation class instances have a single, async method,write. It uses fsPromises.writeFile(), and does path.join(filePath, fileName) for the location. Any files which already exist will be replaced.

API

Property	What you need to know
count	Number. How many files to make
filePath	String. Base path for where the files will be written. If it does not exist, it will be created recursively.
fileName	String. Template for the name of the file. %ID% will be replaced with the ID as described above.
content	String. What goes in the file. %ID% will be replaced with the ID as described above.
