Redirection
PHP 
JavaScript 
Redirection is a WordPress plugin to manage 301 redirections, keep track of 404 errors, and generally tidy up any loose ends your site may have. This is particularly useful if you are migrating pages from an old website, or are changing the directory of your WordPress installation.
Note: this is the current 'trunk' version of Redirection. It may be newer than what is in the WordPress.org plugin repository, and should be considered experimental.
Installation
Redirection can be installed by visiting the WordPress.org plugin page:
https://wordpress.org/plugins/redirection/
Customisation
Redirection provides a large set of WordPress action and filter hooks that can be used to extend or customise the plugin. These can found on the Redirection Hooks page.
Permissions
Access to the Redirection admin interface is given to users who can manage_options. You can modify this with permission filters, described on the Redirection permissions page.
Building
Redirection is mostly a PHP plugin, but does contain files that need to be built. For this you'll need Gulp, Node, and Yarn installed. Install required modules with:
yarn install
Language files
gulp pot - Updates language files
React
Some parts of the UI are React and can be built with:
yarn build
To use in development mode then set REDIRECTION_DEV_MODE to true in PHP, and run:
yarn start
This will start Webpack in hot-reload mode, and you can make changes to JS files and have them auto-loaded.
Releasing
Finally, to produce a release copy:
gulp plugin
