Browser error messages referencing correct typescript file using outFile

问题

I am using the outFile option in the tsconfig.json to compile my typescript files into one .js file.
I am generating a source map.
Error messages are not referenced to the typescript file though.

Examples:

---

script.ts: throw 'Error'
tsconfig.json:

{
  "compilerOptions": {
    "sourceMap": true
  }
}

Compiling (tsc 1.6.2) will generate:
script.js: throw 'Error
script.js.map: {"version":3,"file":"script.js","sourceRoot":"","sources":["script.ts"],"names":[],"mappings":"AACA,MAAM,QAAQ,CAAC"}

The browser's console (Chrome 47.0.2526.73 m) will display: Uncaught Error. script.ts:1

That's just fine.

script.ts: throw 'Error'
tsconfig.json:

{
  "compilerOptions": {
    "sourceMap": true,
    "outFile": "app.js"
  }
}

Compiling (tsc 1.6.2) will generate:
app.js: throw 'Error
app.js.map: {"version":3,"file":"app.js","sourceRoot":"","sources":["script.ts"],"names":[],"mappings":"AACA,MAAM,QAAQ,CAAC"}

The browser's console (Chrome 47.0.2526.73 m) will display: Uncaught Error. app.js:1

It is app.js it should be app.ts

How can I get the browser to reference error messages to my typescript files?

回答1:

I have used the same version of Chrome browser. However ts compiler version is 1.7.3

Dev tools console is opened.

1 case:

• ts.config

  { "compilerOptions": { "sourceMap": true } }

• app.ts

  throw 'some error in my typescript';

• dev tools console:

  app.ts:5Uncaught some error in my typescript(anonymous function) @ app.ts:5

2 case:

• ts.config

  { "compilerOptions": { "sourceMap": true, "outFile": "src.js" } }

• app.ts

  throw 'some error in my typescript';

• dev tools console:

  app.ts:5Uncaught some error in my typescript(anonymous function) @ app.ts:5

If a dev tools console is closed, the page is refreshed, then you will open the dev tools console, then you can see the following:

src.js:4 Uncaught some error in my typescript

But if you refresh the page again with opened dev tools console, you can see ts file as a source of error.
