Spawn

Use JSTime.spawn() to spawn a child process.

const proc = JSTime.spawn(["echo", "hello"]);

// await completion
await proc.exited;

---

The second argument accepts a configuration object.

const proc = JSTime.spawn("echo", ["Hello, world!"], {
  cwd: "/tmp",
  env: { FOO: "bar" },
  onExit(proc, exitCode, signalCode, error) {
    // exit handler
  },
});

---

By default, the stdout of the child process can be consumed as a ReadableStream using proc.stdout.

const proc = JSTime.spawn(["echo", "hello"]);

const output = await new Response(proc.stdout).text();
output; // => "hello"
