Which files are generated when executing `dart2js`? and why?

dart2js probably generates .js.map, .js.deps and .precompiled.js.

What's the purpose of them? and I donno why dart2js doens't remove them after finishing compile.

Solution

  • All files are generated by dart2js on purpose:

    .js: The JavaScript output of your application

    .precompiled.js: The JavaScript output but with content security policy (CSP) support

    .js.map: source map file used for debugging the JavaScript code in the browser. It contains a mapping from JavaScript to Dart code lines.

    .js.deps: contains a list list of all references files used for compilation, prop ably for debugging but I'm not sure about this.
