Setup

First clone/fork the repo and cd into it.

git clone https://github.com/imranhsayed/nextjs-headless-wordpress.git
cd nextjs-headless-wordpress

• Install Docker from docs.docker.com/get-docker ( this step may not be required if you are using your own WordPress setup.)

It's very simple to setup the project with just one command and this ./nxtwp configure

One command project setup

The below command is going to set up the project in the interactive mode. It creates an .env file for front-end next.js project and setsup up frontend and/or backend. Run this from the root of the project.

./nxtwp configure

It's going to ask you a few of questions.

Q1. Do you already have a WordPress setup that you want to continue with? [y/n]:

Answer

y: If you would like to use this project's WordPress Docker setup ( In which case make sure to install and active all plugins from [backend/plugins-collection]) n: If you want to use your own WordPress setup.

Q2. ✍️  What is your WP backend URL? (defaults to http://localhost:8020): 

Leave it blank if you would like to use this project's WordPress Docker setup, else enter your own WordPress site URL.

✍️  What is your frontend next js URL? (defaults to http://localhost:3000):

Leave this blank for development, as it will be the same as default for next.js

✍️  What is your Disqus comments shortname? (leave blank if you are not using): 

Leave this blank if you are not going to use the Disqus comments, else enter your Disqus comments shortname.

This is going to automatically:

• Creates the .env file in the frontend directory.
• Setup WordPress backend with all the plugins via composer (if you chose y for the first question)
• Install npm packages for next.js frontend and start development server.

WordPress Backend will be available on http://localhost:8020 Next.js Backend will be available on port http://localhost:3000

• Make sure to activate all plugins that it has installed via composer.
• Update block registry by going to WordPress Dashboard > GraphQL Gutenberg.
• Update the permalink by going to Settings > Permalinks > Post name > Save
• Copy the backend/wordpress/.htaccess file content into your WordPress .htaccess
• For more information checkout the project Wiki

That's it!

During development

Useful commands: To be run from the root of the project.

./nxtwp configure       # Sets up backend and frontend and creates an .env file
./nxtwp start-all       # Creates and starts docker environment for WP and runs Next JS server
./nxtwp start-backend   # Creates and starts docker environment
./nxtwp start-frontend  # Installs all packages and Runs Next JS server
./nxtwp stop            # Stops the WordPress docker containers

Debugging

1. If you get 404 on frontend for graphql request, check to see that the .htaccess file in wordpress directory has the rules

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

2. If front-end is throwing some other error.

• Check if all the required WordPress plugins form backend/plugins-collection are active.
• Ensure you have updated the block registry from WordPress backend > GraphQL Gutenberg
• Ensure that .env file has correct env variables and their values in frontend/.env
