Create an API

[Jenselme]

It’s kind of required for #156 We could rely on the existing code used by the app, but we will have CSRF issues by default and the user must be logged in the app (no idea how the login form could behave with an extension (and with MFA) and we don’t want to store passwords in the configuration of the extension). So this requires an ADR and some experimentation to see how hard it is to build the api.

In the long run, it’s a valuable addition to help users automate things. We won’t try to make an API follow an existing one (like the one from TTRSS) for now.

We need to be able to:

• Subscribe to feeds.
• For each subscribed feed, we want to:
  • Change the tags associated with it.
  • Change the category.
  • Delete the feed.
• Save articles.
• For a saved article, we want to:
  • Change the tags associated with it.
  • Mark it as read, favorite or for later.
  • Correct the title.
  • Correct the reading time.
  • Delete the article.
• List all feeds with pagination.
• List all feed categories with pagination.
• Create a feed category.
• Update a feed category.
• Delete a feed category.

We target what we need for the browser extension for now. We will improve the API later in #320
