Discord as a Backend

npx skills@latest add phucbm/skills --skill discord-as-backend

I didn't want to run a database for a list of links, so a Discord forum is the database. Each link is a thread in a forum channel: the thread's name is the title, its tags are the tags, its first message holds the URL. A bot token reads the channel, and the references on this site are that channel. The other direction is a webhook: Hiểu Chữ Hán's "report an issue" form posts into a channel, with no bot and no auth beyond the webhook URL.

What broke

• Active and archived threads are two calls. Archived ones come from the channel; active ones only from the whole server, so they have to be filtered by parent_id. Miss one and half the links disappear depending on when Discord archived them.
• Archived threads come 100 at a time. phucbm-web read the first page and stopped. This site pages through them with before, because the channel passed 100.
• One request per thread adds up. The first message is a separate call per thread. On a Cloudflare Worker that is a budget (50 outside requests a run on the free plan), so this site reads the URL from the thread's name when it is there, and remembers the ones it had to look up.
• The webhook URL is a password. Anyone with it can post to the channel, so it stays on the server and the form goes through an API route.
