90fc281e90 v4: every image the API serves comes scaled to the size it is shown at — a first visit to the feed loaded 4.8 MB of images out of 5.1 MB in all: an avatar shown at 32 pixels was the upload itself, a 1.4 MB GIF among them, and so were a cover, a custom thumbnail, an attachment and a proxied image, only an image dump having a preview, 960 pixels wide. Every route that answers an image now takes ?w= and sends a WebP copy at most that wide, of the widths shared/image.ts lists, 128, 320, 640 and 960, a width between two taking the one above, and never wider than the image; without it the upload goes out as before, a dump's thumbnail alone being scaled to the widest by default, the custom ones included. serveImage (lib/upload.ts) is where they all end, and the image proxy scales what it fetched the same way, keeping each width in its cache. lib/ffmpeg.ts makes the copies as it made the previews, which they replace: on first request, under uploads/scaled/ at the upload's own path, each given its upload's date and made again when the two differ, so a new avatar or cover needs nobody to delete the old ones. WebP keeps a PNG's transparency and a GIF's animation. A JPEG is turned by its EXIF orientation here, ffmpeg's own rotation of images depending on its version. An animated WebP, which ffmpeg can't read, and an image it fails on go out as they are, a failure being remembered until the upload changes. ?f=compat asks for the copy as a JPEG, or a PNG for what may be transparent: the digest's emails take their thumbnails that way, at 640 pixels, not every mail client reading WebP. On the client, imageProps (utils/shared/urls.ts) gives an image its srcset of those copies and the width it is laid out at, which config/imageSizes.ts states for each place from App.css: Avatar, Thumbnail, which scales an API image and leaves another site's as that site sends it, and the playlists' covers use it. The images of notes and comments still load as uploaded. The copies go with the dump, the custom thumbnail or the attachment they were made from, and generatedMediaSweepJob, a minute after the start then daily, takes those whose upload is gone, the previews under their former name and the temporary files a generation left unfinished.

4468438ba7 v4: every page and API URL follows one of two rules, written down in API.md — pages are a hierarchy where @name is a user and any other root word a category or an app page, tabs and views are plain segments and a default view is the bare path; API resources are /api/<plural>/<key>, a user's key being an id or @name, the caller's things under /api/me, media a sub-resource, lookups by another key a query filter. ~ is gone: the feed is /, /hot, /new, /journal, /follow and /music/hot, a profile /@bob with its overview and the tabs dumps, upvoted, playlists (her own only), follow (users, and /follow/playlists), invitees and manage (role and name, for user:manage), which replace the separate UserDumps, UserUpvoted and UserPlaylists pages; /settings holds the account (now with the username) and /manage the category manager, both linked from the user menu and one's profile. Dumps and playlists live under their owner, /@bob/dumps/<slug> and /@bob/playlists/<slug>, named by slug alone: migration 0021 re-slugs them to the bare slugify(title), unique per owner and kind (the oldest keeps it, clashes get -2), renames the categories whose slug v4 reserves (hot, follow, settings…), and rewrites this site's v3 links in dump notes, comments, chat, and playlist and profile descriptions. A slug changes only when edited, through the edit forms' new link field, which proposes slugify(title) as the title changes; a username changes from /settings or, for user:manage, from /@name/manage. Every slug or name left behind stays an alias of its item or user for good (dump_slug_aliases, playlist_slug_aliases, user_aliases), so old links redirect without chaining and nobody else can take one; slugs change 3 times a day per item, names once in 30 days, moderators exempt. An alias, or a name in another case, answers the item with its current path: the pages put it in their URL (useCanonicalPath, without fetching again), and the OG middleware answers a 301. shared/paths.ts builds and parses every page path, for the client's links, the emails' (digest-service lost its own builders and its id fallbacks, and links /follow and /settings) and the server's matchers (OG tags, self previews, backlinks, self-url); shared/slug.ts holds slugify and the format categories share. Dumps and playlists carry ownerUsername and a required slug, and notifications join their users' current names and their items' paths each time they are sent or read, so renames reach them and a deleted item's has no link. The API was renamed per the plan's table: POST /api/users and /api/sessions, /api/password-resets, /api/me (with settings, password, avatar, media-token, playlists?contains=, follow, feed?from=, notifications), /api/users/:key/{dumps,upvoted,playlists,follow/users,follow/playlists,invitees,avatar} and by path /api/users/:key/{dumps,playlists}/:slug, /api/dumps?url= and ?category=, /api/dumps/:id/{file,thumbnail,metadata}, /api/playlists/:id/cover, /api/remote/{preview,image,bandcamp,youtube} (one router), and /api/unsubscribe, the v3 POST /api/users/unsubscribe staying for the digests already sent. A stored default feed tab "followed" reads as "follow" once. dumps.slug and playlists.slug stay nullable, since SQLite can't add NOT NULL without rebuilding tables others reference; every writer sets them and unique (user_id, slug) indexes hold them. 254 backend tests (new: migration 0021 on a v3 fixture, slug aliases, swaps and rate limits, username renames, aliases and limits, reads by path and their privacy, the OG 301s, both unsubscribe paths, v4-shaped digest links with no ids, notification joins, shared paths and slugs) and 668 frontend tests (new: the profile's tabs and follow views, Settings, Manage, the link field, canonical URLs on the dump, playlist and profile pages, bare default feed paths) pass, and tsc, eslint, deno check, deno lint, deno fmt and doc:lint are clean; the migration was also run on a copy of the development database.
