Use answer-coverage in TypeScript

Install with npm install jev-recipes. Requires Node.js 22.9 or newer and ES modules. Set TYPESAFE_API_KEY in your server environment for live calls, which send input to TypeSafe and use API quota. See the installation guide.

import { answerCoverage } from 'jev-recipes/answer-coverage';

const result = await answerCoverage({
  "draft": "Select Forgot password on the sign-in page.",
  "questions": [
    {
      "id": "reset",
      "text": "How do I reset my password?"
    },
    {
      "id": "expiry",
      "text": "When does the link expire?"
    }
  ]
});
console.log(result);
