Automating WordPress Development with Make

Modern WordPress development is complex. This means that switching projects or letting a project sit for a period of time can lead to a learning curve similar to when you first started the project.

It doesn’t have to be like this. If doesn’t matter if your WordPress project is using Composer, React, Yarn, NPM or some other technology. You can easily automate common tasks across multiple projects with a single file in a system that is probably already running on your dev computer and those of your team.

Enter GNU Make

GNU Make (or just Make from here on) has been around a very long time. Its original purpose was to make your program with a series of targets. For example, if you were compiling a program that created a file called my_program.exe you would create a make target simply called my_program.exe that contained the necessary instructions, however complex, to build your file.

Today it can still be used to compile applications and create files but it is just as useful as a task runner to help consolidate all the tasks around your WordPress project.

Think of Make as a sort of CI/CD for your local application. Instead of something like GitHub Actions or CircleCI running a list of pre-defined tasks, you simply specify the tasks you want (now called targets in Make) and call them from the terminal when you need them.

Getting started with Make

Getting started with Make is easy. In the root of your application simply create a file called Makefile and save it. That’s it.

Of course an empty Makefile doesn’t have any targets so we’ll want to change that. The first thing I normally do is add a help target. In the future running make help will give me all the information I need to remember the various targets in my application. Here’s how it looks:

.PHONY: help help: ## Display help @awk -F ':|##' \ '/^[^\t].+?:.*?##/ {\ printf "\033[36m%-30s\033[0m %s\n", $$1, $$NF \ }' $(MAKEFILE_LIST) | sort
Code language: Makefile (makefile)

A few things to note on this:

First is the .PHONY line. This is followed by the name of our target, in this case help. Remember earlier when I said Make was originally used to make the files we need to use in our application? This is a relic of that. In this case we’re telling it that help is not a real file we’re creating. It’s a “PHONY” target instead. You’ll want to use this for almost every target you create.

Now notice the second line. It starts with the name of our target, help, followed by ## and a description of the command. If we were to call this it would output every target in our make file followed by such a description.

How do we call it? Simply run the following:

make help
Code language: Makefile (makefile)

This syntax, “make” followed by our target, is how we’ll call any other target we want to utilize.

You can also chain tasks together under a single target. For example, say you had a target called “build” and you wanted it to build your composer and npm assets. In this case I would set it up as three targets, build, build-composer, and build-npm. You could then invoke the main build target with the following:

.PHONY: build build: build-composer build-npm ## Build all composer and npm assets
Code language: Makefile (makefile)

Notice above I have the PHONY target as well as the description from before. If we were to call make help here it would should the build target along with our description above. Unlike the help target above, however, this one doesn’t do anything by itself. It simply calls the build-composer and build-npm targets we define elsewhere.

An Example Make Script

Below is an example Makefile I’m using for a small plugin I’m building. This Makefile allows me to check out the repo from GitHub and simply run make start to setup a development environment complete with a running site, appropriate coding standards, and even a few debugging plugins to make it all easy to work with. As a bonus, I could pass this repo to someone else, even if they aren’t familiar with my setup, and they could get up and running and working on code within minutes instead of the hours that some modern WordPress projects take.

Code language: Makefile (makefile)

If you want to try this Makefile yourself you can find the source at Note the Makefile above is only promised to be current at the time this post is published and the file itself will evolve over time.

What all does it do? Well, you could run make help on it to find out but here’s a breakdown of the important parts:

  1. It installs all plugin dependencies via composer
  2. It installs the latest version of WordPress as well as a few development plugins to make work on it easier
  3. It runs all unit tests including setup, teardown, etc
  4. It can create a “release” file I can then upload to my site
  5. It runs the WordPress coding standards against any code I write
  6. If I screw something up it can completely reset it all in a single command
  7. It can clean-up everything it’s done when I stop working on the plugin

Try it yourself

If you write code for WordPress you owe it to yourself to give Make a try. It doesn’t care what library or tech you use, it’s an old and proven technology and a little practice with it will give you an easy workflow that will translate across projects. From building assets to running dev sites and from automated testing to releasing your product, Make is a tool that can take any complex project and make it as simple as a single command.
