Next.js

Create a Next.js Project

To create a new Next.js project, run the following command:

npx -y create-next-app@latest remult-nextjs

When prompted, use these answers:

✔ Would you like to use TypeScript? ... Yes
✔ Would you like to use ESLint? ... No
✔ Would you like to use Tailwind CSS? ... No
✔ Would you like to use `src/` directory? ... Yes
✔ Would you like to use App Router? (recommended) ... Yes
✔ Would you like to customize the default import alias? ... No

Afterward, navigate into the newly created project folder:

cd remult-nextjs

Install Remult

Install the latest version of Remult:

npm install remult

Bootstrap Remult in the Backend

Remult is bootstrapped in a Next.js app by creating a catch-all dynamic API route. This route will pass API requests to an object created using the remultNextApp function.

1. Create an API file

   In the src/ directory, create a file called api.ts with the following code to set up Remult:

   // src/api.ts
   
   import { remultNextApp } from 'remult/remult-next'
   
   export const api = remultNextApp({})

2. Create the API Route

   In the src/app/api directory, create a [...remult] subdirectory. Inside that directory, create a route.ts file with the following code:

   // src/app/api/[...remult]/route.ts
   
   import { api } from '../../../api'
   
   export const { POST, PUT, DELETE, GET } = api

This file serves as a catch-all route for the Next.js API, handling all API requests by routing them through Remult.

Enable TypeScript Decorators

To enable the use of decorators in your Next.js app, modify the tsconfig.json file. Add the following entry under the compilerOptions section:

// tsconfig.json

{
  ...
  "compilerOptions": {
    ...
    "experimentalDecorators": true // add this line
    ...
  }
}

Run the App

To start the development server, open a terminal and run the following command:

npm run dev

Your Next.js app is now running with Remult integrated and listening for API requests.
