azs allows you to add virtual methods to zod schemas, tying data types to functions. here's a small example for a user type.
A more advanced example can be found here.
import {z} from 'zod';
import azs from 'azs';
const userSchema = z.object({
age: z.number(),
name: z.string(),
github: z.string().url(),
});
const schema = azs(userSchema, {
// Basic example
isAdult: user => {
return user.age >= 18;
},
// Methods can take arguments, but the
// first argument will always be the parsed
// value. You also don't have to type
// the first argument.
is: (user, name: string) => {
return user.name === name;
},
// Or, you can access `this` which will be
// the parsed value
getName() {
return this.name;
},
});
const user = schema.parse(someRandomJSONThatMightBeAUser);
user.isAdult();
user.getName();
user.is('Colin McDonnell');
