The Power of TypeScript's Satisfies Operator - snippet-9.ts

snippet-9.ts

type Endpoint = {
  url: string
  method: 'GET' | 'POST'
}

const endpoints = {
  getUsers: { url: '/users', method: 'GET' },
  createUser: { url: '/users', method: 'POST' },
  // Forgot an endpoint? TypeScript can help if you use a stricter type
} satisfies Record<string, Endpoint>

// Later, you get full autocomplete
fetch(endpoints.getUsers.url) // '/users' - literal type!
