🔥 Example of react application to access WordPress REST API

1. Clone this repo in git clone https://github.com/imranhsayed/react-workshop

2. Run npm install

A React App where you can login using the endpoint provided by JWT Authentication for WP-API WordPress Plugin. So you need to have this plugin installed on WordPress. The plugin's endpoint returns the user object and a jwt-token on success, which we can then store in localstorage and login the user on front React Application

• You need to install and activate JWT Authentication for WP REST API plugin on you WordPress site
• Then you need to configure it by adding these:

i. Add the last three lines in your WordPress .htaccess file as shown:

# BEGIN WordPress
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /wordpress/
   RewriteRule ^index\.php$ - [L]
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /wordpress/index.php [L]
   
   
   RewriteCond %{HTTP:Authorization} ^(.*)
   RewriteRule ^(.*) - [E=HTTP_AUTHORIZATION:%1]
   SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
   
   </IfModule>

ii. Add the following in your wp-config.php Wordpress file. You can choose your own secret key.

define('JWT_AUTH_SECRET_KEY', '&BZd]N-ghz|hbH`=%~a5z(`mR=n%7#8-Iz@KoqtDhQ6(8h$og%-IbI#>N*T`s9Dg');
define('JWT_AUTH_CORS_ENABLE', true);

iii. Now you can make a request to /wp-json/jwt-auth/v1/token REST API provided by the plugin. You need to pass username and password and it returns a user object and token . You can save the token in localstorage and send it in the headers of your protected route requests ( e.g. /wp-json/wp/v2/posts )

iiv. So whenever you send a request to WordPress REST API for your protected routes, you send the token received in the headers of your request

{
	'Accept': 'application/json',
	'Content-Type': 'application/json',
	'Authorization': `Bearer putTokenReceivedHere`
}

A React(front end) + Node(back end) application. It uses jwt.sign() ( from jwtwebtoken npm package ) to generate a token using the username and password sent from front end( React ) and returns it as a response, which we then store in localstorage to login the user. This token received by frond end, will be sent with all further request for protected routes, which will then be verified in node route using jwt.verify() Besides generating the token, the end point in node also accesses the WordPress rest api to confirm the credentials and returns the user object or errors if any.

It also has functionality to create post where we make a request from front end along with token( React ) to a node end point. The node endpoint verifies the token and then makes a request to WordPress REST API endpoint to create the post and then returns the new post id, or error if any.

Contains features of jwt-verify-with-node and its an app ready to deploy to heroku

• start Runs node server for development ( in watch mode ). The server.js sends all front end route request to index.html and then all front end route requests is handled by reach router
• prod Runs webpack in production mode
