How can I make the errors shown in the console refer to the typescript source maps in an angular cli project?

Question

I have just issued the ng new exampleProject command. When an error appears in the console, the stacktrace shows only .js files: not the .ts files. How can I change this?

Here is an example of such an error:

Answer 1

console.trace()

The above code helps to get the complete trace of where the error has occurred in angular including the line number, component name and the function name.

Answer 2

Add "sourceMap": true, in compilerOptions in your tsconfig.json
