tsnodewronglinenumber

This repository contains a set of files showing that ts-node error stack provide wrong line numbers.

The problem is tricky to reproduce, as it seem to depend on what module is imported, etc.

To reproduce, run sh ./run.sh. It will show that with tsc the line numbers are correct, and that with some modules the lines are correct, while with ts-node and some module, they are incorrect.

Output of the test:

$  sh run.sh
==> Checking with zwave-js with tsc and ts-node on js file:
$ rm -fr dist; tsc; ts-node dist/err_check.js
node_modules/zwave-js/build/lib/node/Node.d.ts:21:22 - error TS2420: Class 'ZWaveNode' incorrectly implements interface 'SecurityClassOwner'.
  Property 'securityClasses' is missing in type 'ZWaveNode' but required in type 'SecurityClassOwner'.
