For an up to date list of available command line options, see:

$> asc --help

API

The API accepts the same options as the CLI but also lets you override stdout and stderr and/or provide a callback. Example:

const asc = require("assemblyscript/cli/asc");
asc.ready.then(() => {
  asc.main([
    "myModule.ts",
    "--binaryFile", "myModule.wasm",
    "--optimize",
    "--sourceMap",
    "--measure"
  ], {
    stdout: process.stdout,
    stderr: process.stderr
  }, function(err) {
    if (err)
      throw err;
    ...
  });
});

Available command line options can also be obtained programmatically:

const options = require("assemblyscript/cli/asc.json");
...

You can also compile a source string directly, for example in a browser environment:

const asc = require("assemblyscript/cli/asc");
asc.ready.then(() => {
  const { binary, text, stdout, stderr } = asc.compileString(`...`, { optimize: 2 });
});
...
