'Build LiveView: async data (assign_async), PubSub (check connected?),.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LiveView Patterns Reference
> **Ash projects**: Use `ash-framework` skill for `AshPhoenix.Form`. Lifecycle: `AshPhoenix.Form.validate/3` on `phx-change`, `AshPhoenix.Form.submit/2` on submit, `to_form/1` for HEEx. Do not use `Ecto.Changeset.cast/3`.
Reference for building with Phoenix LiveView 1.0/1.1.
## Iron Laws — Never Violate These
1. **NO UNCONDITIONAL DB QUERIES IN MOUNT** — Mount runs TWICE. Default: `assign_async`. SEO routes: `connected?` guard + cache-backed disconnected branch (crawlers read that HTML)
2. **ALWAYS USE STREAMS FOR LISTS** — Regular assigns = O(n) memory per user. Streams = O(1)
3. **CHECK connected?/1 BEFORE SUBSCRIPTIONS** — Prevents double subscriptions
4. **EXTRACT VARIABLES BEFORE assign_async CLOSURE** — Closures copy entire referenced variables
5. **LOAD PRIMARY DATA IN mount/3, PAGINATION IN handle_params/3** — handle_params runs on EVERY URL change
6. **NEVER PASS SOCKET TO BUSINESS LOGIC** — Extract data before calling contexts
7. **CHECK CHANGESET ERRORS BEFORE UI DEBUGGING** — Silent form save = check `{:error, changeset}` first, not viewport/JS

How to install
mdr add oliver-kriska/claude-elixir-phoenix/liveview-patterns@sha256:5aad44a4d4d36930The line at the top of this page pins the label git:20260929.c08ad14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
