Breakpoints jump to a different line #76

Open jochem725 opened 6 years ago

jochem725 commented 6 years ago

I’ve set up react-native-typescript-transformer using the guide described on the website of React Native both using an existing react-native project with version 0.55.1 and a clean project with version 0.56.0.

In both versions, if I use this in combination with VSCode and Chrome setting a breakpoint on a line makes it jump to a different line. Could this be an issue with the generated source maps?

I’ve created a sample project [here] based on the typescript article on the RN blog (https://github.com/jochem725/ts-breakpoints). The steps to reproduce (on iOS) are

Launch App using XCode
Enable remote debugging
Attach debugger in VSCode
Set breakpoint (i.e. on Hello.tsx line 67)

If you do this, you will see the breakpoint jump to a different line.
