⚠️ Early stage of development.

My own JavaScript runtime - currently, just randomly messing around with v8 engine in C++. Very unstable as I learn how things work together.

TODO:

• Try to bind SWC (written in Rust) into my C++ codebase
• Integrate my async IO library for runtime's event loop: luxio (renamed to pandio, runtime will use updated version soon).
• Create timers
• Clunky TCP support
• Basic support for ES6 imports
• Improve TCP module
• Improve memory management and fix potential leaks
• File system module

Current state example:

import { 
  assert, 
  assertThrows,
  assertStrictEqual  
} from 'std:assert';
import { tcpListen } from 'std:net';

function willThrow() {
  throw new Error("Some error");
}

Runtime.argv.forEach(item => {
  console.log(`Arg: ${item}`);
});

assert(2 + 2 == 4);
assertThrows(willThrow);
assertStrictEqual(2, 2);

console.log(`Platform is ${Runtime.platform} and pid is: ${Runtime.pid}`);
console.log(`Cwd is: ${Runtime.cwd()} and runtime version is: ${Runtime.version}`);
console.log(`Dirname: ${import.meta.dirname}`)
console.log(`Filename: ${import.meta.filename}`);
console.log(`Url: ${import.meta.url}`);

tcpListen((socket) => {
  console.log("Client connected");

  setTimeout(() => {
    socket.close();
  }, 5 * 1000);

  socket.read((chunk) => {
    console.log(`Received data`);
    const response = `<h1>${chunk}</h1>`; // echo HTTP request
    socket.write(`HTTP/1.1 200 OK\r\nContent-Length: ${response.length}\r\nContent-Type: text/html\r\nConnection: close\r\n\r\n`);
    socket.write(response);
  });
}, 8000);
