Using "resolveJsonModule: true" causes drastic compilation error

[ORESoftware]

I am on: Version 2.9.1

So I have this project, with lib and dist and "outDir":"dist" and "include": ["lib"] ...
that means the only thing that ends up in dist, should be what's in lib, right?

https://github.com/ORESoftware/npm-link-up

This project has a single straightforward tsconfig.json file.

How to replicate the problem :

1. git clone https://github.com/ORESoftware/npm-link-up.git
2. rm -rf dist
3. tsc
4. dist should have some 20+ files in it. These files are the correct files.
5. rm -rf dist
6. change "resolveJsonModule": false, to "resolveJsonModule": true
7. tsc
8. now dist should have about 3 files in it. These files are the incorrect files.

I would assume that "resolveJsonModule": true would not do that much except allow you to do:

import json = require('../../my.file.json');
const jsonType = typeof json;

I don't see why it should have such a drastic affect on what goes from lib into dist.

when you use "resolveJsonModule": true you are telling the compiler to include the .json files imported from your .ts files as part of your project. the files will be emitted to the output, just like all your .ts/.tsx files.

The addition of new files not under lib results in the output folder structure changing.. see more details about this in https://github.com/Microsoft/TypeScript/wiki/FAQ#why-does---outdir-moves-output-after-adding-a-new-file
