Does a JavaScript source map file still work after minimizing the source code file?

Question

My background

I use TypeScript and Visual Studio to compile awesome strongly typed syntax into slutty JavaScript. I've configured the project and Visual Studio to do the following:

1. Combine multiple compiled JavaScript files to a single JavaScript file
2. Generate a source map file

In my generated JSON object that is found in the generated source map file, I can see in his "names" property a whole lot of references to method names and other stuff that occurs in my original TypeScript .ts files. These "symbol names" (as the specification proposal like to call them) also occurs in my final .js file.

The one problem that I seek to solve is to minimize the generated JavaScript file, yet keep all the cool functionality a source map file provides.

The question

Since I haven't figured out how to make Visual Studio himself minimize the JavaScript file and then generate the awesome source map file (how?), what would happen if I use another tool to do the minification; would the untouched source map file still work as intended?

My worries is largely because I assume that the tool will provide new symbol names in the minified file. Of course, the most preferred solution for me would be to have Visual Studio do the minification himself before generating a source map file.

Answer 1

One part of the answer is that the latest version of the TypeScript compiler, as of now, does not support minification.
