Eliminate all citation markers in the final compiled result

Currently, I am consolidating all my .ts files into a single file using the following command:

tsc -out app.js app.ts --removeComments

This is based on the instructions provided in the npm documentation. However, even after compilation, all reference tags are retained in the generated code. From what I understand, there is no practical use for these in JavaScript.

For instance, consider the TypeScript files below:

Application.ts

/// <reference path="../references/backbone.d.ts" />

module Example {
  export class Application extends Backbone.View<Backbone.Model> {
    ...
  }
}

and

app.ts

/// <reference path="Example/Application.ts" />

import Application = Example.Application;

class App extends Application {
  ...
}

after compilation, they result in something similar to:

/// <reference path="../references/backbone.d.ts" />
var __extends = (this && this.__extends) || function (d, b) {
    ...
};
var Example;
(function (Example) {
    var Application = (function (_super) {
       ...
    })(Backbone.View);
    Example.Application = Application;
})(Example || (Example = {}));
/// <reference path="Example/Application.ts" />
var Application = Example.Application;
var App = (function (_super) {
    ...
})(Application);
//# sourceMappingURL=app.js.map

While I definitely want the sourceMappingURL included, the --removeComments flag does not eliminate the reference tags. Are these tags necessary in debugging scenarios with source maps? Is there an option to exclude them from the compiled output?

Answer №1

There are a couple of approaches for eliminating the references, as highlighted in the feedback.

  1. One way is to eliminate the need for /// <reference> tags by utilizing tsconfig.json. For instance:

    /// <reference path="../references/backbone.d.ts" />
    

    can be replaced with

    {
      "compilerOptions": {
        ...
      },
      "files": [
        'references/backbone.d.ts'
      ]
    }
    

    within tsconfig.json.

  2. Alternatively, if you prefer not to use a configuration file, you can minify the compiled JavaScript using a tool such as Closure Compiler to strip away all comments and references.
