Contributing to angular compiler

Question

I was trying to fix a bug in angular-core repository. I have build the project with bazel successfully on my local and got a dist/ folder.

I want to debug this file, For example: Add some console.log() statements to print values of variables. https://github.com/angular/angular/blob/master/packages/compiler/src/parse_util.ts

What is the best way to debug code of this file. I am using tsc filename and then tryting to run the compiled js via Node.js . I am getting errors as the compiles js contains import and export statements not supported by Node.js.

Any Angular Core developer who can give me some help in it. I will be very thankful to him.

Thanks

One way is to use ts-node ( https://github.com/TypeStrong/ts-node ), to execute the file.

Something like this should work:

ts-node index.js --inspect

Use the output to debug the application in chrome.
