RSS Feed Changelog Block for React

Edit FORMATS at the top of the file: each format has an id, a label, an address and a short line on what it suits (suits). The addresses here use feedloom.example, a domain that cannot belong to anyone, so replace it. Drop a format by deleting its object; the choice and the field follow.

Yes: it writes the address to the clipboard, swaps its icon for a check for a moment, and a polite status inside the button says "Feed address copied". If the browser refuses (no permission, or a page not served over HTTPS) the icon turns into a cross and the status says it couldn't copy. Selecting the field also selects the whole address, so it can be copied by hand. The button starts over when you pick another format.

They carry the same entries. RSS 2.0 is the oldest and works in every reader; Atom carries a time zone on every entry; JSON Feed is the easiest to read from a script. The line under the choice says this for the one selected, in a line that keeps its height so nothing moves.

The format choice is a single-choice group that is never empty: Tab enters it and the arrow keys move between the three. The address field is read-only but focusable, named "Feed address", and the button is named "Copy feed address". The entries are articles with a heading each, and the type tags say their word as well as showing an icon.

Edit ENTRIES, newest first: each has a version, an ISO date, its kinds, a title and a summary. Keep to three to five: more belongs behind a link.

Below md each entry stacks its version, day and tags under the text, and a long address scrolls inside its field instead of widening the page, so nothing scrolls sideways at 320 pixels. The address and the versions stay left to right in a right-to-left layout while the rest mirrors.
