Validation with Joi

The library provides a small helper function that makes sure the request body matches the given schema.

To use it, you must also have joi installed as a dependency.

Usage

Import the joi helper function and wrap the action you want to validate with it. The first argument is the schema, and the second argument is the action itself.

import { joi } from "sveltekit-superactions";
import Joi from "joi";

export const POST = endpoint({
  // body must be a non-empty string, otherwise the request fails
  greet: joi(Joi.string().min(1), async (e, body) => {
    // the type of body is inferred as string
    return { greeting: `Hello, ${body}` };
  }),
});
