Adding the certificate to your keychain

To avoid the red "your connection is not encrypted" message, you'll have to add the generated .cert to your keychain.

register_meta and the REST API

In the year since 4.8, confusion about how to properly expose meta information through the REST API has been one of the most prevalend issues we've seen in support posts and tickets.

Most developers try to use register_meta with show_in_rest => true; unfortunately register_meta works on object types, not subtypes, so you cannot pass a custom post type name into register_meta like you can with register_rest_field. Worse, if you register meta for the type 'post', then that meta key is registered not just for core posts, but for every single custom post type. Meta almost never applies across all post types, so this behavior forces developers to use register_rest_field for REST API data modeling instead of taking advantage of the API's built-in meta handling.

there is no way to and this behavior makes it impossible for a developer to register meta that is specific to their single post type. and requires any REST API data modeling to use register_rest_field

REST API Contributor Day

Plan for the day

  • Improve documentation
    • Something we explain very poorly in the REST API handbook; hoping to explain it today to de-mystify
    • Handbook is what was on -- some stuff in there is very good and some that is out of date
    • We have some guides but they are not organized
    • We want to come up with a coherent content architecture
  • Expand the endpoints presented by the API
  • Auto Close Tag
  • Babel
  • EditorConfig for VS Code
  • ESLint
  • File Utils
  • Git History (git log)
  • Go
  • IntelliSense for CSS class names
  • Jest
  • Markdown Shortcuts
