Dart pub
ParseJS is a JavaScript parser for Dart. It is well-tested and is reasonably efficient.
import 'package:parsejs/parsejs.dart';
void main() {
new File('test.js').readAsString().then((String code) {
Program ast = parsejs(code, filename: 'test.js')
// Use the AST for something
})
}
The parsejs function takes the following optional arguments:
filename: An arbitrary string indicating where the source came from. For your convenience this will be available on Node.filename and on ParseError.filename.firstLine: The line number to associate with the first line of code. Default is 1. Useful if code was extracted from an HTML file, and you prefer absolute line numbers.handleNoise: If true, parser will try to ignore hash bangs and HTML comment tags surrounding the source code. Default is true.annotate: If true, parser will initialize Node.parent, Scope.environment, and Name.scope, to simplify subsequent AST analysis. Default is true.parseAsExpression: If true, the input will be parsed as an expression statement.Add this to your package's pubspec.yaml file:
