plugin-updater

An OpenCode plugin that tells you when your plugins and built-in tools have updates waiting, and applies them on the next restart.

The problem

OpenCode installs npm plugins and managed tools (prettier, pyright, bash-language-server, …) into ~/.cache/opencode/packages, but nothing ever updates them. Whatever version was current when a package was first cached stays there forever. There's no update check, no notification, and no command to update them. The only remedy is manually deleting cache directories.

What it does

It compares the installed version of every plugin and managed tool against latest on the npm registry — once a day on startup (24h between checks), and freshly every time you open /plugin-updates:

• If it finds updates, you get a toast: N OpenCode updates available. Run /plugin-updates to review them.
• /plugin-updates (command palette or slash command) opens a screen with three groups (Plugins, Managed tools, Skipped) showing installed → latest per package. Opening the screen always re-checks now (ignoring the 24h timer), so the list is never stale.
• Select what you want (Space / A), press U, confirm, and OpenCode installs the fresh versions itself on the next restart.

The plugin never installs or deletes anything directly. Confirming marks the stale cache entries for removal; when OpenCode exits, they're cleaned up and the built-in resolver installs fresh versions on the next start. Until you restart, nothing on disk changes.

Failures are contained: one unreachable package shows as unknown and doesn't break the cycle; a total registry outage keeps the last result on screen.

What gets checked

• Floating plugin specs from opencode.json and tui.json (union, exact duplicates checked once), like foo and foo@latest. [spec, options] tuple entries contribute their spec string.
• Managed tools: the bundled tools OpenCode installs for you (prettier, pyright, …).

Skipped, with the reason shown on screen: pinned specs (foo@1.2.3), local paths, file:/git+/URL specs, and semver ranges. Those change only when you change them, so updating them automatically makes no sense.

Install

Install with the OpenCode CLI — it detects the TUI target and registers the plugin in tui.json for you:

opencode plugin @glaicer/supercode-plugin-updater

• --global installs into the global config (~/.config/opencode); default is local (.opencode in the current project).
• --force replaces an already-installed version.
• Restart OpenCode after installing.

Manual install also works: add the package to the plugin array in tui.json (global ~/.config/opencode/tui.json or local <project>/.opencode/tui.json):

{
  "plugin": ["@glaicer/supercode-plugin-updater"]
}

Important

The first OpenCode load after installing this plugin may be slow. That's OpenCode downloading the plugin's packages and managed tools into its cache — it happens once. Every subsequent start is fast.

Key	Action
j / k or arrows	Move the cursor
Space	Toggle the package under the cursor
A	Select every selectable package
U	Prepare updates for the selection (confirm dialog first)
R	Re-check again (opening the screen already re-checks; no toast)
Esc	Close

Pinned, unknown, and skipped rows are shown for information but can never be selected. Confirming shows a pending-restart banner: the marked cache entries are removed when OpenCode exits, and the next start installs the new versions.

Development

npm run build       # precompile the Solid TUI entrypoint into dist/
npm run typecheck   # tsc --noEmit
npm test            # node --test, network-free: registry and cache are fixtures
