no-emit-in-root-config

Require "noEmit": true in the root tsconfig.json file.

Targeted pattern scope

The compilerOptions.noEmit field in the root-level tsconfig.json.

What this rule reports

This rule reports when the root tsconfig.json file does not set "noEmit": true in compilerOptions, or sets it to false.

Why this rule exists

In this plugin's opinionated model, the root tsconfig.json should coordinate other configs or provide shared settings, not emit JavaScript itself. Requiring "noEmit": true makes that separation explicit and avoids accidental output from the root config.

❌ Incorrect

{
    "compilerOptions": {
        "outDir": "./dist"
    }
}

The root config is allowed to emit because noEmit is not enabled.

✅ Correct

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

When not to use it

Disable this rule when the root tsconfig.json is intentionally also the emit config for the project.
