Creating a REST Endpoint

Using novel new api

You can use the scaffolding CLI to generate a rest endpoint for you. This is the easiest way to create a REST endpoint.

novel new api

Follow the instructions and your new API should be in /app/api.

Manual Creation

1

Create a new directory in `/app/api`

Create a new directory with the kebab-case format that identifies the function of the endpoint uniquely.

A good format is [subject]-[action]

Examples:

• user-create

• post-search

2

Create a new index.js or index.ts file inside the directory

Copy the template file below

/app/api/user-create/index.ts

export default function Handler(instance) {
    instance.post('/your/endpoint', handler);

    async function handler(request, reply) {
        // your logic
    }
}

New endpoints are not picked up by the server hot reload. You will need to restart the novel dev server

Routing Options

Routes | Fastifyfastify.dev

Using OpenAPI

You can generate OpenAPI schemas based on Fastify's validation and serialization model

Validation-and-Serialization | Fastifyfastify.dev

/app/api/user-create/schema.json

{
    "body": {
        "type": "object",
        "properties": {
            "id": {
                "type": "string"
            }
        }
    }
}

This is automatically loaded into your route.

Validation

Because of Fastify's validation model, request input is already controlled on a framework level. If you prefer to validate further, you can make use of zod internally like so:

Basic usage | ZodZod

/app/api/user-create/index.ts

import Accounts from 'novel/models/accounts';
import { z } from 'zod';

export default function Handler(instance) {
    instance.post('/your/endpoint', handler);

    async function handler(request, reply) {
        if (Accounts.z.safeParse(request.body)) {
            // your logic
        }
        if (z.safeParse(request.body)) {
            // your logic
        }
    }
}
