Features

Implement Standard JSON Schema

standard-schema/standard-schema#134
Implement z.fromJSONSchema()

const jsonSchema = {
  type: "object",
  properties: {
    name: { type: "string" },
    age: { type: "number" }
  },
  required: ["name"]
};
const schema = z.fromJSONSchema(jsonSchema);

Implement z.xor()

const schema = z.xor(
  z.object({ type: "user", name: z.string() }),
  z.object({ type: "admin", role: z.string() })
);
// Exactly one of the schemas must match

Implement z.looseRecord()

const schema = z.looseRecord(z.string(), z.number());
// Allows additional properties beyond those defined
