another copy of javascript when adding tsconfig.json

[tepid palm]

i just started to add a tsconfig.json to my /convex dir and im getting a copy of js file for every ts file i wrote. this hasnt been the case in the past and i wonder if i've configured something wrongly? here's my tsconfig.json:

{
  /* This TypeScript project config describes the environment that
   * Convex functions run in and is used to typecheck them.
   * You can modify it, but some settings required to use Convex.
   */
  "compilerOptions": {
    /* These settings are not required by Convex and can be modified. */
    "allowJs": true,
    "strict": true,
    "skipLibCheck": true,

    /* These compiler options are required by Convex */
    "target": "ESNext",
    "lib": ["ES2021", "dom"],
    "forceConsistentCasingInFileNames": true,
    "allowSyntheticDefaultImports": true,
    "module": "ESNext",
    "moduleResolution": "Node",
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react"
  },
  "include": ["./**/*"],
  "exclude": ["./_generated"]
}

thank you 🙂

i manually deleted all the js files

Not sure what you mean when you say you added this, Convex generates this file in the convex directory. Did you make any specific changes?

nope. my convex/ dir didnt have a tsconfig originally. i just pasted the file above and got an extra copy of duplicate *.js for every file i have under convex/

This link below is what convex generates. The only difference I see is the added jsx property, but that shouldn't cause what you're seeing. The noEmit property should keep it from generating source files.

Try to exclude convex/ from your parent tsconfig? convex should not be generating js files either way, but your other build system (Vite/Next.js etc.) might.
