01 Examples

TypeScript

catch (error) { if (error.message.includes("missing")) return null; throw error; }

Finding

Disallow control flow coupled to exception prose.

02 Enable it

Setup

Install the package, register its plugin factory, then enable the rule.

pnpm add -D @scruple/errors

In scruple.config.ts, register the factory under the errors namespace used by the rule ID.

import { errors } from "@scruple/errors";

plugins: {
  "errors": errors(),
},

"errors/no-message-based-error-dispatch": "warn"
