What are from2-array's main functionalities?

Create a readable stream from an array

This feature allows you to create a readable stream from an array of values. The stream emits each value in the array as a chunk of data.

const from2Array = require('from2-array');
const stream = from2Array(['a', 'b', 'c']);
stream.on('data', (chunk) => {
  console.log(chunk.toString());
});

Create a readable stream from an array with a custom read function

This feature allows you to create a readable stream from an array with a custom read function. The custom read function can be used to control how data is read from the array.

const from2Array = require('from2-array');
const stream = from2Array.obj(['a', 'b', 'c'], (size, next) => {
  next(null, this.values.shift() || null);
});
stream.on('data', (chunk) => {
  console.log(chunk);
});
