👷‍♀️ node-inline-worker

Moves a node module into a Node.js Worker, automatically reflecting exported functions as asynchronous proxies.

Dev.to Article

You might already be familiar with the Workerize npm package, which is the web counterpart for this module. The feature list and API are the same:

• Bundles a tiny, purpose-built RPC implementation into your node app
• If exported module methods are already async, signature is unchanged
• Supports synchronous and asynchronous worker functions
• Works beautifully with async/await

Available for Node >=12 without runtime flags. Uses node's Worker Threads.

Install

npm install --save node-inline-worker

Usage

Pass a function to be executed in the Worker thread

const workerize = require('node-inline-worker')

const add = workerize(async (a, b) => {
  await new Promise(resolve => setTimeout(resolve, 1000))
  return a + b
})

async function main () {
  // Pre-curried use
  console.log('3 + 9 = ', await add(3, 9)) // Logs after 1 second
  console.log('1 + 2 = ', await add(1, 2)) // Logs after 1 second

  // Direct invocation
  const sequence = await workerize(function fib (n) {
    return n <= 1 ? n : fib(n - 1) + fib(n - 2)
  })(10)

  console.log(sequence) // logs `55`
}

main()
