Transpile Alan to Javascript

Run Alan in the browser or Node.js.


For alan-js-runtime Node.js is required, with a minimum version of 10.20.1.


To install alan-js-runtime, run:

npm i -g alan-js-runtime

Writing a Hello, World! Example

Once everything is installed, first create a file named hello_world.ln and then write the following within it:

import @std/app

on app.start {
  app.print("Hello, World!");
  emit app.exit 0;

Next run:

alan compile hello_world.ln hello_world.js

This will produce a JS file that depends on the alan-js-runtime. If it is globally installed, you can simply run:

node hello_world.js

which prints Hello, World!
