Using FireCMS with Next.js

It is perfectly possible to use FireCMS with Next.js. FireCMS is a React library, so you can use it with any React framework.

In the case of next.js, you are restricted to running FireCMS in the client side, as next.js does not support server side rendering of some of the React components used by FireCMS.

Start by creating your next.js project:

npx create-next-app@latest

Then install FireCMS and its dependencies:

yarn add firecms@^2.0.0 firebase@^9 @mui/material@^5 @mui/icons-material@^5 @mui/lab@latest @mui/x-date-pickers@^5.0.0-beta.1 @emotion/react @emotion/styled react-router@^6 react-router-dom@^6

Configuring the App router

Next.js uses a file based router. In this guide, we will be creating the FireCMS app in the /cms route, but you can customize this to your needs.

FireCMS uses react-router, so we need to configure next.js to delegate all the routes starting with /cms to FireCMS.

FireCMS does not require tailwind since it relies on Material UI, so you can opt-out of it when creating the project.

In our app folder, we create a folder called cms and inside it another one called [[...any]]. This will match any route starting with /cms.

Then create the file cms/[[...any]]/page.tsx with the following content:

import CMS from "@/app/cms/CMS";

export default function Home() {
return <CMS/>;
}

Creating the CMS

You can now create your CMS as you would normally do. Create the file cms/CMS.tsx with the following content:

important

If you are not running FireCMS in the root path of you app, you need to set the basePath prop to the path where you are running it. In this case, we are running it in /cms.
