Description

The defineString function does not narrow the type when adding input.select.options. This means we have to typecast in certain situations, even though we know what the types should be.

Code sample

const environmentParam = params.defineString("ENVIRONMENT", {
      default: "production", // This will now error out if it does not match one of the options
      input: {
        select: {
          options: [
            { label: "Production", value: "production" },
            { label: "Staging", value: "staging" },
            { label: "Development", value: "development" },
          ],
        },
      },
});

const environment = environmentParam.value();
// ^? "production" | "staging" | "development"

Limitations

• If defaultValue is provided with no options the value is still wide, rather than loose autocomplete
