Type-checking errors aren't reported

Since there are no instructions for running the plug-in within parcel I assume it is supposed to work automatically - is that right? - but for me it doesn’t.

My parcel --version is 1.9.0 but during installation I’m told “npm WARN parcel-plugin-typescript@1.0.0 requires a peer of parcel-bundler@^1.9.0 but none is installed. You must install peer dependencies yourself.”

Any ideas? I installed both with --global, then tried reinstalling parcel-bundler and parcel-plugin-typescript with --save-dev; this time I got v1.9.1 and the warning message did not appear, but when running .\node_modules\.bin\parcel there is no sign that the plugin is running, e.g. no type errors.

Other warnings did appear:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

the needs-repro can be removed, I suppose.

@QuantumInformation Fixed it by adding: “parcelTsPluginOptions”: {}, to the tsconfig file. Now its able to parse correctly as expected 👍

NOTE: if you have a , on the last line in “compilerOptions” it breaks. Removing this comma, fixes the issue. https://stackoverflow.com/questions/201782/can-you-use-a-trailing-comma-in-a-json-object/201856#201856
