Simple WordPress health check endpoint

composer require frosty-media/wp-health-check

Composer autoloading should be including in application's bootstrap, in this case the wp-config.php file.

If running Nginx, add the following to your sites conf rules:

rewrite ^/meta/health-check/?$ /vendor/frosty-media/wp-health-check/src/check.php last;

If running Apache, add the following to your .htaccess file (before any WordPress rules):

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^meta/health-check/?$ /vendor/frosty-media/wp-health-check/src/check.php [L]
</IfModule>

If you would like to include the MU Plugin (which creates the internal REST API route wp-json/health/check?) Update your scripts.post-update-cmd, or run composer config scripts.post-update-cmd.0 "FrostyMedia\\WpHealthCheck\\Composer\\Scripts::postUpdate"

{
  "scripts": {
    "post-update-cmd": [
      "FrostyMedia\\WpHealthCheck\\Composer\\Scripts::postUpdate"
    ]
  }
}
