Codecs

You can use Zod z.codec() schemas to store arbitrary data types such as class instances within CoValues by defining custom encoders. This allows you to directly use these data types within CoValues without having to do an extra manual conversion step.

#Using Zod codecs

To use a Zod z.codec() with Jazz, your encoder must encode the data into a JSON-compatible format. This is means that the Input type shall map to the JSON-compatible type, and Output will map to your custom type.

class Greeter {
  constructor(public name: string) {}

  greet() {
    console.log(`Hello, ${this.name}!`);
  }
}

const schema = co.map({
  greeter: z.codec(z.string(), z.z.instanceof(Greeter), {
    encode: (value) => value.name,
    decode: (value) => new Greeter(value),
  }),
});

const porter = schema.create({
  greeter: new Greeter("Alice"),
});

porter.greeter.greet();
