Reopening of #25636 which doesn't seem to have fixed all problems reported in that issue

🕗 Version & Regression Information

This is the behavior in every version I tried (up until 4.1)

💻 Code

import data from "./data.json";

export default { data };

{
  "extends": "../tsconfig.base.json",
  "compilerOptions": {
    "composite": true
  },
  "include": ["./**/*"]
}

🙁 Actual behavior

$ tsc --build tsconfig.json
feature-two/index.ts:1:18 - error TS6307: File '/Users/sebastian.silbermann/ts-references-json/feature-two/data.json' is not listed within the file list of project '/Users/sebastian.silbermann/ts-references-json/feature-two/tsconfig.json'. Projects must list all files or use an 'include' pattern.

1 import data from "./data.json";
                   ~~~~~~~~~~~~~


Found 1 error.

Explicitly adding .json to include like #25636 (comment) suggested works also but is unintuitive since the extension is only required in composite projects.

🙂 Expected behavior

Compiles just fine without having to add another include pattern using .json.

The json files are not included by include pattern unless you specify the ".json" extension so per your include pattern in tsconfig the root files is "index.ts" and does not include "data.json". Composite wants you to list all input files and data.json is not part of your config and hence error. This is working as per design.

When you look at explain files it shows that "data.json" is included only through import and not any of the config file rules.

You can fix this as suggested in #25636 by either adding files or include with json pattern.

We also have test case

While this may be what you intended when implementing, it's not intuitive from a user perspective.

Given that data.json will be copied to your outDir it seems correct that it should be listed in your config.

But while writing above comment i realised, your config doesnt have outDir. So it seems like a bug where data.json shouldnt need to be listed?

Note that if we change this, it also means that not listing data.json has implications on tsc --build only root files specified by config are checked if anything changed with respect to output and with this it will not rebuild project if data,json gets updated after project was successfully built.
