Is it possible to get a readable stack trace for a webpack production environment for a minified bundle with dev-tool set to source-map? I am running Typescript and react with a Webpack build. An example of an exception that is being thrown is shown in the listing below:

http://localhost:8080/vendors~course-list.3042c44300bc08021f63.bundle.js:2:6029
http://localhost:8080/vendors~course-list.3042c44300bc08021f63.bundle.js:2:5067

in w in b in withRouter(b) in e in e in Suspense in div in e in e in S

In the above stacktrace the following observations can be made with the devtool option set to source-map:

  • names remain minimised, e.g. w, b and e.
  • minimised error locations are reported, e.g. line number and column numbers.

I'm using this npm package and it works great :)

https://www.npmjs.com/package/sourcemapped-stacktrace

Example:

    import * as sourceStackTrace from 'sourcemapped-stacktrace';
    ...

    const minifiedStack = new Error().stack;
    sourceStackTrace.mapStackTrace(minifiedStack, (stackTrace: string[]) => {
        // Do your thing here
    });
