TS6307: JSON files not in file list when using composite projects

[thovden]

Expected Behaviour

Using resolveJsonModule and composite projects works as tsc does.

Note that tsc has had some issues with this that were solved in microsoft/TypeScript#25636 and that tsc works correctly now. See reproduction below.

Actual Behaviour

ERROR in ./tsloader-ts6307/tsconfig.composite.json
[tsl] ERROR
      TS6307: File 'tsloader-ts6307/src/test.json' is not in project file list. Projects must list all files or use an 'include' pattern.

Steps to Reproduce the Problem

$  git clone [email protected]:thovden/tsloader-ts6307.git
$ cd tsloader-ts6307/
$ npm i

# tsc works well for the composite config
$ npm run tsc

# webpack + ts-loader works without composite set
$ npm run works
[./src/test.json] 20 bytes {main} [built]
    + 12 hidden modules
ℹ ｢wdm｣: Compiled successfully.

# webpack + ts-loader fails with composite
$ npm run fails
ERROR in ts6307/tsconfig.fail.json
[tsl] ERROR
      TS6307: File 'ts6307/src/test.json' is not in project file list. Projects must list all files or use an 'include' pattern.
ℹ ｢wdm｣: Failed to compile.

I get these intermittently in VS Code as well, so perhaps here is some funkiness in the typescript servicehost that affects both ts-loader and VS Code

[johnnyreilly]

Possibly.... Have you bumped on this @andrewbranch?

[andrewbranch]

Hmm, nope, that's new to me. Would be happy to take a look at it sometime, but I'm about to be traveling (without a computer) for the next few weeks 🙈

[johnnyreilly]

Have great travels! It's good to be away from the keyboard every now and then 😁

@stalebot relax, I'll put it on my to-do list

[webberwang]

I'm getting this as well:

is not in project file list. Projects must list all files or use an 'include' pattern.

I have

include: ['src/**/*', 'src/**/*.json]

set inside tsconfig.json, and the setting is working for tsc but not ts-loader.

[andrewbranch]

This appears to be a TypeScript bug here: https://github.com/microsoft/TypeScript/blob/eeba30afc81e2c7c8a34a2deb0d4d2375a1c21f6/src/compiler/program.ts#L2771-L2774

I think either the JSON file should be in the program’s rootFiles when resolveJsonModule is true (there are a few different places that prevent this from happening), or sourceFileMayBeEmitted() is returning true for the JSON file when it should be returning false. (To clarify—it’s definitely returning true, I think it's possible it should be returning false.)

Here's a minimal repro:

Compile with:

import * as ts from 'typescript';

const commandLine = ts.parseJsonSourceFileConfigFileContent(ts.readJsonConfigFile('tsconfig.json', ts.sys.readFile), ts.sys, '.');
console.log(commandLine.fileNames);

const program = ts.createProgram({
  rootNames: commandLine.fileNames,
  options: commandLine.options,
});

const diagnostics = program.getOptionsDiagnostics();

console.log(ts.formatDiagnostics(diagnostics, {
  getCanonicalFileName: fileName => fileName,
  getCurrentDirectory: ts.sys.getCurrentDirectory,
  getNewLine: () => '\n',
}));

tsconfig.json

{
  "compilerOptions": {
    "moduleResolution": "node",
    "target": "es5",
    "composite": true,
    "resolveJsonModule": true
  },
  "include": [
    "*.ts",
    "*.json"
  ]
}

foo.ts

import * as foo from './foo.json';

foo.json

{}

/cc @sheetalkamat what's the expected behavior here?

[sheetalkamat]

@andrewbranch This works with tsc but not with the sample repro code you gave because your base path is not resolved? (changing that to say 'c:/temp/test2' works). That's because https://github.com/microsoft/TypeScript/blob/master/src/compiler/commandLineParser.ts#L2729 expects basePath to be the first thing in the json matching pattern

[andrewbranch]

Ah yes, that does fix my repro. I think ts-loader must be making a similar mistake, because the JSON files were definitely not in the program. This really helps narrow it down, thanks!

[xtianus79]

this is still an issue

[mvargeson]

Has anybody come across a workaround for this issue (other than not using composite projects)?

[andrewbranch]

I’ll try to take a look at this over the weekend.

[johnnyreilly]

You are a prince among men @andrewbranch 🤴

[berickson1]

I spent a couple hours digging into this after @mvargeson shared with me. Ideally you'd be able to use the regex generated internally by the typescript compiler instead of generating our own but I couldn't find a way that it was exposed.

[mrcaidev]

Still an issue

[malshoff]

Bump, ended up here from Google and it is still an issue.

[SalahAdDin]

It is still an issue.

Any updates on this?
