TypeScript strict (strict)

typescript-config/strict checks if the property strict is enabled in your TypeScript configuration file (i.e. tsconfig.json).

Why is this important?

By enabling the strict compiler option of TypeScript, the compiler will run in the strictest of the modes catching more typing issues before runtime.

What does the hint check?

This hint checks if the compilerOptions property strict is enabled.

Examples that trigger the hint

By default, TypeScript doesn’t enable the strict mode:

{
    "compilerOptions": {
        "target": "es5",
        ...
    },
    ...
}

Also setting the value to false will fail:

{
    "compilerOptions": {
        "strict": false,
        ...
    },
    ...
}

Examples that pass the hint

strict value is true:

{
    "compilerOptions": {
        "strict": true,
        ...
    },
    ...
}
