node_preamble.dart

A simple package for a better dart2js preamble for running on node.js. This package exists for ease of use if incorporating into your build system.

This preamble is suggested for use over d8.js, and provides many improvements and bug fixes, as it uses node.js's timer functions and event loop over the custom one implemented in d8.js.

The JavaScript file can be found at lib/preamble.js.

You can also get the preamble via Dart, like in the following example.

import "package:node_preamble/preamble.dart" as preamble;

main() {
  print(preamble.getPreamble());
}

Credit goes to the Dart team for creating Dart, dart2js, and the original preamble which this is derived from.

1.4.0

  • Add __dirname and __filename to exposed globals. Adds ability of exposing more globals in the preamble by calling getPreamble(additionalGlobals: ["__dirname", ...]).

1.3.0

  • Add minified versions of the preamble accessible as lib/preamble.min.js and by calling getPreamble(minified: true).

1.2.0

  • Prevent encapsulation, global.self = global (old) vs. var self = Object.create(global) (new).

1.1.0

  • Set global.location so that Uri.base() works properly on Windows in most cases.

  • Define global.exports so that it's visible to the compiled JS.
