@trpc/react 9.12.0 on Node.js NPM

Add PRECONDITION_FAILED / HTTP 412 error code (#1194)
Input schemas defined with zod using the inferred input type (#1189 / #1182)

What #1189 means is that you can now do this code:

trpc.router()
  .query('greeting', {
    input: z.object({
      hi: z.string().transform(s => s.length),
    }),
    resolve({ input }) {
      input.hi // => `number`, as expected
    },
  });

// [...] somewhere else:

client.query('greeting', { hi: 'my greeting' });
