In this 4 minute demo, Pawel shows you how Backtrace supports SourceMaps with a sample Electron app written in TypeScript. You will see how without SourceMap files, Backtrace will only show the faulting line number from the transpiled javascript file. This isn’t very useful to the TypeScript developer. When proper SourceMaps are uploaded to Backtrace, you will see the proper TypeScript line numbers show.
