When you develop themes or plugins, it can be helpful to have WordPress tell you what's going on when something is not working quite right. To make this possible, there are a handful of plugins that you can choose to install in your site for debugging purposes. All of these plugins have been bundled into one super plugin called Developer that's available directly from the WordPress Plugin Directory. To install Developer, all we have to do is go to the dashboard of our locally hosted sites, go to plugins, and click Add New and then search for Developer.
This will return a search with the Developer plug in probably on top and you can install it directly from here. And once you activate this plugin, it immediately asks you what type of content you will be developing. So here we have to walk-through this process. Thanks for installing the Developer Helper Plugin. Before we begin, what type of website are you developing? So here you have a choice between plugin for a self-hosted WordPress, a theme for a self-hosted WordPress, or a theme for WordPress.com VIP. So I'm going to select theme for a self-hosted WordPress installation, click save changes.
And now the Developer Plugin will give me a list of recommended plugins I can choose to install if I wanted to. So here you can choose any one of these plugins or all of them or none of them. And it's completely up to you, you can come back and change these installs at any time. This is simply a place where you get all options right off the bat so you can pick what you want. So I'm going to select debug bar, and debug bar console, and Chron, and extender, and I'm going to select the monster widget, and regenerate thumbnails and that's all I need for right now.
I'm actually going to be using several of these plugins later on in the course, in particular, the Monster widget and the Regenerate thumbnails plugin. So, if you're at this point, I recommend you install them now so you don't have to do it later. But, like I said, if at some point later on you realize you need some of these features, you can simply go back and install them. So, for now, I've installed the plugins I want. I'm going to click Get Developing and I'm taken back to the Plugins screen. If I now want to change my setup, I can simply go to my Admin panel, go to Tools and Developer, and from here you see we have a different display, but it has all the same options.
Here we have the project type and we have all the available plugins, and you can see which ones are active and which ones are not installed so that we can click to install them. Having these developer plugins installed can help you quickly identify and fix problems in your theme as you're developing it. My advice to you is to start with the key ones I pointed out during the installation process, and then add on more later if you want more in-depth analysis or more information.
