Documentation clarification of topic "Modules Resolution"?

[JasonKleban]

It's very important to be aware that this plugin uses TypeScript's, not webpack's modules resolution. It means that you have to setup tsconfig.json correctly. For example if you set files: ['./src/index.ts'] in tsconfig.json, this plugin will check only index.ts for errors.

Does this mean that imports of index.ts will not be explored/checked? That was my initial interpretation, but then that behavior wouldn't match typescript's module resolution either - it would be basically no module resolution. I guess if build: true it would match, but if build: false then files array is just the entry points for the transpilation graph.

I'm trying to debug a build issue, and I need to gain confidence on this point, please. I'm running forked v6.2.1 and not getting any errors listed. Kind of like #319 except that's claimed to be fixed in v6.

That's a good point - you're right, we should update the doc :) Would you like to create a PR to update it?

[JasonKleban]

Thanks! But I don't know the complete correct answer to know what to replace it with.

The plugin will use the same module resolution as TypeScript. The simplest option to check whether it's a configuration issue or a bug in the plugin is running the tsc command - in your case, it should be tsc --build --watch. If it works in TypeScript, then the issue is in the plugin, otherwise, the issue is in the configuration or TypeScript itself :)

I will close this issue - if you find any problems with the build mode, please open another one with a description and reproduction repository :)
