WP REST API Requests logger

Great for debugging and also a great way to quickly fill up the log with new events. A lot of what’s happening in WordPress and the Gutenberg/Block Editor is happening using the REST API.

The WP REST API requests logger will log all usage of the built in REST API. See GET, POST, DELETE, PUT requests, their REST ROUTE and what parameters (GET and POST) they used.

Did I mention it’s great for debugging, for example when developing Gutenberg Blocks. Or when building a logger plugin like Simple History! ✋

Log emails sent via WP-Mail

The WP-Mail Logger catches all emails send using the built in wp_mail() function and adds them to the log. You’ll get a quick preview of sent emails, including subject, recipients, and content. A nice way for developers and other curious users who wants to know what’s being sent from their WordPress sites.

If an email for some reason can no be sent, details about these failures are also logged:

Using WP-CLI commands you can easy retrieve the email details from the terminal.

In the example below we use the terminal commands WP-CLI and jq together to show details about a single history event, and to only show the message_interpolated and event_details fields.

Log outgoing HTTP requests

With the HTTP Requests logger you can log and inspect any outgoing HTTP requests made with for example wp_remote_request(), wp_remote_get(), wp_remote_post() or the WP_HTTP class directly.

This is a great debug tool during development of sites when you need to debug outgoing API requests.

When a lot of requests are being requested to the same base URL, the requests are grouped together. So for example all calls to wp-cron.php won’t pollute your screen with 16 items, but rather just one where you can choose to show all other requests to the same URL.

Log cron events that have run

The WP-Cron logger logs wp cron jobs that have run.

In the log you can see when cron jobs are ran and view details about function called, arguments passed, their schedule, and so on.

A useful debugging tool for developers that are implementing or debugging wp cron jobs.

Details about the cron event includes hook, timestamp, arguments, and hook information.
