How to fix Option 'declaration' cannot be used without 'emitDeclarationOnly' when 'noEmit' is set in TypeScript

{
  "compilerOptions": {
    "noEmit": true  // Pick ONE strategy - this disables ALL output
  }
}

{
  "compilerOptions": {
    "emitDeclarationOnly": true,  // Emit only .d.ts files
    "declaration": true
  }
}

{
  "compilerOptions": {
    "declaration": true,  // Emit .d.ts alongside .js
    "noEmit": false       // Explicitly allow emission (or omit, default is false)
  }
}

{
  "compilerOptions": {
    "noEmit": true,
    "emitDeclarationOnly": true  // These conflict!
  }
}

{
  "compilerOptions": {
    "noEmit": true,
    "declaration": true  // This requires output!
  }
}

{
  "compilerOptions": {
    "noEmit": true
  }
}

{
  "compilerOptions": {
    "emitDeclarationOnly": true,
    "declaration": true
  }
}

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "emitDeclarationOnly": true  // Overrides noEmit from base
  }
}

cat tsconfig.base.json | grep -A5 '"compilerOptions"'

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "noEmit": false,  // Override inherited noEmit
    "emitDeclarationOnly": true,
    "declaration": true
  }
}

{
  "compilerOptions": {
    "noEmit": true,
    "target": "ES2020",
    "module": "ESNext"
  }
}

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "noEmit": false,
    "declaration": true,
    "outDir": "./dist"
  },
  "include": ["src/**/*"]
}

# Type check (no output)
tsc --noEmit

# Build (emits .js and .d.ts)
tsc --project tsconfig.build.json

# Check for errors (no output files created)
npx tsc --noEmit

# Or build if using emitDeclarationOnly
npx tsc
