Multiple tsconfig.json bug

[mctep]

• VSCode Version: 1.13.1
• MacOS Version: 10.12.5

Project has next files:

/server.ts
/tsconfig.json
/client/client.ts
/client/tsconfig.json

// server.ts
typeof window;
typeof global;

// tsconfig.json
{
  "compilerOptions": {
    "lib": ["es2015"],
    "types": ["node"]
  }
}

// client/client.ts
typeof window;
typeof global;

// client/tsconfig.json
{
  "compilerOptions": {
    "lib": ["dom"],
    "types": []
  }
}

Steps to reproduce

Case 1

1. Open project in VScode with any closed tabs code ..
2. Open client/client.ts.ts in VScode. There is right error [ts] Cannot find name 'global'
3. Open server.ts. Right erorr [ts] Cannot find name 'window';
4. Close client.ts. Open client.ts.
5. Focus server.ts. There are no errors. All types have found.
6. Close server.ts. Open server.ts. Right erorr [ts] Cannot find name 'window'.

Case 2

1. Open project in VScode with any closed tabs code ..
2. Open server.ts. Right erorr [ts] Cannot find name 'window';
3. Open client.ts. Wrong erorr [ts] Cannot find name 'window';

I've created repo for reproducing bug: https://github.com/mctep/vs-code-tsconfig-bug

@mctep the tsconfig.json you have at the root applies to both, by default if you don't specify, it acts as though you did "include": "**/*.ts"

./node_modules/.bin/tsc --noEmit
client/client.ts(1,8): error TS2304: Cannot find name 'window'.
server.ts(1,8): error TS2304: Cannot find name 'window'.

You should add "files" or "include"/"exclude" to the tsconfig.json to make sure there is only one tsconfig per input file. It is ok for multiple declaration files to be selected by more than one tsconfig, but it never has worked well to have multiple 'tsconfig.json' files per .ts file.

you can check by doing

./node_modules/.bin/tsc --noEmit --listFiles
./node_modules/.bin/tsc --noEmit --listFiles -p client

tsconfig.json

{
  "compilerOptions": {
    "lib": ["es2015"],
    "types": ["node"]
  },
  "exclude": [
    "client",
    "node_modules"
  ]
}

client/tsconfig.json

{
  "compilerOptions": {
    "lib": ["es2015", "dom"],
    "types": []
  }
}

OR

{
  "compilerOptions": {
    "lib": ["es2015"],
    "types": ["node"]
  },
  "files": ["server.ts"]
}

client/tsconfig.json

{
  "compilerOptions": {
    "lib": ["es2015", "dom"],
    "types": []
  },
  "files": ["client.ts"]
}

"files" only needs to be entry points, you can still import files outside, but don't import a non-declaration file from both the client and server, ideally you want to compile a shared lib generating declaration files to use in the client and server.

When you shared ts files between tsconfig it is based on the ordering of open/closing which "project" they become part of, because they are part of both.

Hm... My bad.

Adding exclude declaration to /tsconfig.json solves the problem. Thank you @krisselden.
