Wiki.js 3.3.0

Wiki.js 3 is a modern wiki: pages written in Markdown, AsciiDoc or a visual editor - by several people at once, live - with content blocks (diagrams, Draw.io, galleries, page includes...), drawings (Excalidraw), page history, comments, approvals, and its own search. It runs natively on the NAS (no Docker), with its own Node.js, and keeps everything in the PostgreSQL app (which it needs: install that first).

• Its address is https://wikijs.<domain>, through the Nginx app (added automatically - rename it there, e.g. to wiki). With the Nginx app installed, Wiki.js is only reachable through it by default (it listens on the NAS itself only, 127.0.0.1:3010). Without the Nginx app (or with that setting off, on the page) it's also at http://<nas-ip>:3010 on the local network, over plain HTTP.
• Its administrator logs in as admin@nas.local, with a password the app generates on its first start (shown on the management page, which can also change it - even after the email address has been changed in Wiki.js). Other people's accounts are added in Wiki.js (Administration, Users): the NAS sends no email unless you set up a mail server in Wiki.js.
• Its database: the app makes a login and a database of its own in PostgreSQL (both wikijs; the login owns the database and nothing else), and Wiki.js adds what it needs to it (the ltree and pg_trgm extensions, its tables in a wiki schema) on its first start - which takes a minute or two. At boot, if PostgreSQL isn't answering yet, Wiki.js waits for it (up to 5 minutes, in the background).
• Backups: every day at 03:25, its whole database (pages and their history, uploaded files, users and settings - Wiki.js keeps them all in it) with PostgreSQL's pg_dump, while it runs, into Nas_Prog/_wikijs/backups (or a folder chosen on the page), keeping the newest 7. To restore one: stop Wiki.js, then, as the PostgreSQL app's postgres user (password on its page):

``sh /mnt/HD/HD_a2/Nas_Prog/postgresql/binaries/postgresql/bin/pg_restore -h /var/run/postgresql -U postgres \ -d wikijs --clean --if-exists --no-owner --role=wikijs /path/to/wikijs-<date>.dump ``

• It runs as its own user (wikijs, ID 99). Its other data is kept in Nas_Prog/_wikijs, across reinstalls and removal: data/ is Wiki.js's own (its cache); its configuration (conf/config.yml, written by the app at every start), passwords, settings and backups are root's. Its database stays in PostgreSQL when the app is removed (drop it there to start afresh: DROP DATABASE wikijs; DROP ROLE wikijs;, and delete Nas_Prog/_wikijs).
• Wiki.js fetches the icons it's asked for from Iconify's service (once - then kept in its database) and checks for new versions; the app also checks weekly for a new release (a NAS alert).
• Not included: PDF export and page images through a browser (Puppeteer - Wiki.js would download Chromium), and Pandoc. Git storage (Administration, Storage) needs a git program: the Forgejo app provides one.
• It's the official release (its server with its packages, and its web interface - checked by its SHA256) with Node.js 26. Wiki.js is AGPL-3.0 licensed. Intel models only.
• Moving from Wiki.js 2: export from 2.x (Administration, Utilities, Export for Wiki.js 3.x), then import here (Administration, Utilities, Import from Wiki.js 2.x) - see Wiki.js's guide.
