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.
