Tiny ESM helpers for reading files line by line.

• Lightweight: tiny wrapper around Node.js core modules with no dependencies.
• Functional API: simple read(handler)(path) style for quick scripting.
• JSONL-friendly: readJson parses one JSON object per line.
• Node 22+ ready: modern ESM and node: imports.

npm i readline-es

import { read, readJson } from 'readline-es';

read((line) => {
  console.log('text line:', line);
})('./example.txt');

readJson((obj) => {
  console.log('json line:', obj);
})('./example.json');

• Creates and returns a Node.js readline.Interface
• Calls onLine(line) for each line when onLine is provided

• Same as read, but each line is parsed with JSON.parse
• Calls onLine(parsedObject) for each JSON line
