gerbeur/API.md

gerbeur's URLs

Every page and every API endpoint follows one of two rules. This file summarizes them. Each router's module doc in api/routes/ lists its own endpoints in full, and a route change updates both. shared/paths.ts builds and parses the page paths.

The two rules

Pages. The path is a hierarchy. @name is a user. Any other word under the root is a category or an app page. Under a user, each segment is a fixed tab name, and under dumps or playlists, a slug. A view of a page is one more segment. A default view is the bare path, with no redirect.

API. A resource is /api/<plural>/<key>[/<noun>]. Its key is its id, except a user's, which may also be @name. The @ keeps the two apart, so no regex sniffing is needed. A read by page path mirrors the page: /api/users/@bob/dumps/<slug>. The caller's own things live under /api/me. Media is a sub-resource. A lookup by another key is a query filter. Each concept has one word, the same as in pages.

Pages

/@<name>/dumps/<slug>/edit		its poster, dump:moderate	DumpEdit

/?share_url= opens the create form on a link shared from Android, /?chat=open opens the chat over any page, and #comment-<id> scrolls a dump's page to a comment.

Names

• Slugs of categories, dumps and playlists are lowercase letters and digits in words joined by single hyphens (shared/slug.ts). A category's is at most 50 characters, a dump's or a playlist's at most 60.
• A dump's or a playlist's slug is made from its title when it is created, unique among its owner's items of that kind: a clash gets -2, -3. It changes only when someone edits it: the edit forms propose slugify(newTitle) when the title changes. Its owner may change it 3 times a day; moderators (dump:moderate, playlist:moderate) may edit any slug, at any time.
• A username is 1 to 32 letters, digits and underscores, unique in any case. A page writes it in its stored case, and another case still resolves. Users can't rename themselves: those with user:manage rename anyone, from /@<name>/manage.
• Aliases. A slug or a name left behind stays an alias for good, which always names the item or user itself, so redirects never chain. Nobody else can take one. An item can take back one of its own. Deleting an item frees its aliases.
• Redirects. A page reached by an alias, or by a name in another case, gets the item from the API under its current path and replaces its URL. The server answers the same path with a 301 to crawlers and full page loads.
• Reserved words. A category can't take a word the root already uses: hot new journal follow search login register notifications reset-password unsubscribe settings manage community api ws assets emojibase (api/lib/reserved-slugs.ts). Dump and playlist slugs reserve nothing, and no slug has an @.

API

Every JSON endpoint answers the envelope of shared/api.ts: { "success": true, "data": … }, or { "success": false, "error": { "code", "message" } } with the matching HTTP status. A list answers { "items", "hasMore" } and takes ?page= (from 1) and ?limit= (20 by default, 100 at most). "Signed in" means a session token as Authorization: Bearer …. Media can't send a header, so a private file, thumbnail, waveform, cover or attachment takes the owner's media token as ?token=.
