What's so exciting about the WordPress REST API? It will allow WordPress developers to build front-end systems independent from the core WordPress package. This will eventually lead to improved mobile apps, thoroughly customized themes and much more.
Some are already using the REST API. Here are the best examples of websites using it before it merges into core WordPress code in WordPress 4.7.
- Event Espresso, a very popular event management plugin, uses it to provide public access to its data.
- Simmer, a recipe publishing tool, is used it to build out their own developer APIs and to help others turn cookbooks into mobile apps that they can sell easily.
- Modern Tribe is building websites that use the REST API to power both Handlebars and full page React templates in themes.
- Human Made uses the API for client projects. For example, they created a Node-powered frontend and use it to maintain the familiar WordPress admin.
- Reactor uses the API to create mobile apps that digest the API themselves.
- Aesop Interactive uses the API to power Lasso and also with the WP Live Search plugin.
- Join In, a site organizing volunteers in the UK, creatively used the API to create an embeddable JS widget.
- Per Soderlind used the WP REST API as a backend for an iOS application for the Norwegian Ministry of Petroleum and Energy.
- According to the Who’s using this thing? post on Make WordPress, many people are currently using the API to create mobile apps for their own websites.
As you can see, the REST API is already being used in various creative ways, and with the merge of this into the core code, we'll surely only begin to see more!
