While the documentation for the Yoast SEO plugin can be found on Yoast.com, here you can browse the source of the project, find and discuss open issues and even contribute yourself.
Here's a guide on how to install Yoast SEO in your WordPress site.
At Yoast, we make use a specific toolset to develop our code. Please ensure you have the following tools installed before contributing.
After installing the aforementioned tools, you can use the steps below to acquire a development version of Yoast SEO. Please note that this will download the latest development version of Yoast SEO. While this version is usually stable, it is not recommended for use in a production environment.
Within your WordPress installation, navigate to wp-content/plugins and run the following commands:
git clone https://github.com/Yoast/wordpress-seo.git
cd wordpress-seoTo install all the necessary dependencies, run the following commands:
composer install
yarn
grunt buildDuring development, you could run grunt build:dev instead of grunt build, to save yourself downloading some dependencies that are only needed for a production environment.
Please note that if you change anything in the JavaScript or CSS, you'll have to run grunt build:js or grunt build:css, respectively.
For active development, you could run grunt watch to keep the build up-to-date and run checks right away.
For JavaScript only, a webpack development server is available. To enable the dev-server, you'll have to add this to your WordPress install's config.php:
define( 'YOAST_SEO_DEV_SERVER', true );and you can start it by running yarn start in the wordpress-seo folder.
Another JavaScript alternative is grunt webpack:watch, this command will keep the JS files up-to-date. You'll have to refresh the page yourself since this does not run a development server.
This repository uses the Yoast grunt tasks plugin.
Yoast SEO uses some JavaScript code that is managed outside of this repository. This code is being maintained in a monorepo: Yoast/javascript. If you need to change anything in one or more of the packages included in the monorepo, you'll need to do the following:
git clone https://github.com/Yoast/javascript.git # Only the first time.
yarn link-monorepo # You will be prompted for the location of your Yoast/javascript clone. This will be "./javascript" if you cloned it inside the wordpress-seo directory. Your preference will be saved in a .yoast file for later use.
grunt buildThis links all Yoast managed JavaScript packages to your installation of the plugin. Most branches on the wordpress-seo repository also exist on the javascript repository. Please find which branch to use in the table below. If the branch you're looking for does not exist, feel free to default to develop (or create the branch yourself if you're making changes).
| Yoast/wordpress-seo | Yoast/javascript |
|---|---|
| master | master |
| trunk | develop |
| feature/x | feature/x |
You can now modify the code of the linked packages directly from the node_modules (as they're now symlinked to your javascript clone) or your javascript directory. Please remember to run a grunt build:js from the wordpress-seo directory after making changes in order to apply those changes to the plugin.
If you don't want to use the latest development version of the Yoast JavaScript packages anymore, you can restore the versions as specified in the package.json by running the following command:
yarn unlink-monorepo
