Usage #
The assert
module #
This module provides a simple set of assertion tests that can be used to test invariants:
final AssertModule _assert = require('assert');
_assert.ok(true); // Returns normally.
_assert.ok(false); // Throws a `JsAssertionError`.
The events
module #
This module provides the EventEmitter
class:
require('events'); // Required: the `EventEmitter` class doesn't exist before this call.
var listener = allowInterop((data) => print('A "eventName" event occurred: ${data['foo']}'));
var emitter = new EventEmitter()..on('eventName', listener);
emitter.emit('eventName', new JsObject.jsify({'foo': 'bar'}));
The path
module #
This module provides utilities for working with file and directory paths:
final PathModule _path = require('path');
print(_path.basename('/foo/bar/baz.txt')); // "baz.txt"
print(_path.dirname('/foo/bar/baz.txt')); // "/foo/bar"
