trek-plugin-sdk

The SDK for building TREK plugins.

Scaffold a plugin

npx trek-plugin-sdk                        # no command? a guided menu of everything below
npx trek-plugin-sdk create                 # interactive wizard (id, location, type, permissions)
npx trek-plugin-sdk create my-plugin --type widget   # or non-interactive
cd my-plugin

The wizard also offers to initialize a git repo and install dependencies for you. In a non-interactive shell (CI, pipes) every command stays flag-driven with plain output — no prompts, and machine output (entry JSON, pack --json, PR URLs) stays on stdout.

Develop with a live reload loop

dev runs your plugin locally — no full TREK needed. It injects a ctx that enforces exactly the permissions your manifest grants (an ungranted call throws PERMISSION_DENIED, so you catch missing grants), backs db:own with a real SQLite file, serves your routes and your page/widget UI, and reloads on save.

npx trek-plugin-sdk dev        # http://localhost:4317 — dashboard, routes, UI

Open /preview to see a page/widget rendered in a real sandboxed frame with a theme/accent/appearance toggle (trek.invoke() is proxied to your routes). Hit a route as an unauthenticated request with ?_anon=1. Drop a dev-fixtures.json (trips, users, config) next to your manifest to feed ctx.trips / ctx.users.

The UI is a sandboxed, opaque-origin iframe that can't load TREK's stylesheet — so the SDK ships it. Put one line in your client/index.html <head>:

<!-- trek:ui -->

dev and pack expand it into the inlined design kit: token-driven styles that follow the host's theme and accent (glass, cards, .trek-btn, .trek-input, .trek-chip, .trek-row, hover), plus a window.trek bridge:

trek.onContext((ctx) => { /* ctx.theme, ctx.tokens, ctx.appearance, ctx.user, ctx.tripId */ })
const data = await trek.invoke('/status')   // calls your own route, host-proxied
trek.notify('success', 'Saved')

The kit applies the theme, mirrors the appearance flags (reduced-motion, no-transparency) and auto-reports your height. See the Plugin Development wiki for the full component + token reference.

Write a plugin

const { definePlugin } = require('trek-plugin-sdk')

module.exports = definePlugin({
  async onLoad(ctx) {
    await ctx.db.migrate('001', 'CREATE TABLE cache (k TEXT PRIMARY KEY, v TEXT)')
  },
  routes: [
    { method: 'GET', path: '/status', auth: true, async handler(req, ctx) {
      return { status: 200, headers: { 'content-type': 'application/json' }, body: '{"ok":true}' }
    }},
  ],
})

Your plugin runs in an isolated child process. ctx is the only way to reach TREK, and it grants exactly the permissions your trek-plugin.json declares — an ungranted call throws PERMISSION_DENIED.

Test without a running TREK

import { createMockHost } from 'trek-plugin-sdk/testing'

const { ctx, broadcasts } = createMockHost({
  grants: ['db:read:trips', 'ws:broadcast:trip'],
  trips: { 1: { members: [42], data: { id: 1, name: 'Japan' } } },
})
// the mock enforces the SAME permission model, so you can prove your plugin
// degrades gracefully when a permission is missing.

Publish — one command

Commit and push your plugin to its public GitHub repo, then:

npx trek-plugin-sdk publish --repo you/repo --tag v1.0.0

publish does the whole release in one go: pack → tag + GitHub release → preflight (runs the registry CI checks locally) → open the registry PR. If preflight finds a problem it stops before submitting, so a broken entry never becomes a doomed PR. It prints the PR URL at the end.

Updating a listed plugin: bump version in the manifest, commit, and run publish again with the new tag — it detects the existing entry and prepends the new version, newest-first.

Prefer to drive the steps yourself? They still exist individually — pack, release (pack → GitHub release → entry), preflight, submit (opens the PR), and entry (just prints the JSON).

Sign your releases (optional, recommended)

Give your plugin a stable identity. TREK pins your key on first install (trust-on-first-use); afterwards an unsigned or wrong-key update is refused.

npx trek-plugin-sdk keygen                                  # once — writes ~/.trek-plugin/signing.key
npx trek-plugin-sdk publish --repo you/repo --tag v1.1.0 --sign

Signing is dependency-free Ed25519 over the artifact bytes. Back up the key — losing it means you can't ship signed updates.

Exports

definePlugin(def) + all the plugin types (PluginContext, PluginRoute, PluginJob, PhotoProvider, CalendarSource).
PLUGIN_API_VERSION — embed as apiVersion in your manifest.
validateManifest(json) — the manifest rules the server loader uses.
createMockHost(opts) (from trek-plugin-sdk/testing).
TREK_UI_CSS, TREK_THEME_JS, TREK_UI_MARKER, injectTrekUi(html) — the design kit, for authors who inline it themselves (a bundler, a custom build). Most plugins just use the  marker instead.

Commands

Run any of these with npx trek-plugin-sdk <command> (or the short trek-plugin bin if you install the package):

create [name] [--type t] [--interactive] — scaffold a plugin; a wizard if you omit the name.
dev [dir] [--port 4317] — run locally with a real request loop, SQLite db:own, and hot reload.
validate [dir] — manifest + layout checks (a subset of registry CI, offline).
pack [dir] [--out plugin.zip] [--json] — build the artifact, print sha256 + size.
keygen [--key file] — create an Ed25519 signing key.
sign [zip] [--key file] — print a signature + public key for an artifact.
entry --repo o/n --tag vX [--merge f] [--sign [key]] [--out f] — emit the registry entry JSON.
preflight --repo o/n --tag vX (or --entry f) — run the registry CI checks locally, over the network.
submit --repo o/n --tag vX [--sign [key]] [--draft] — open the registry PR for you.
release [dir] --repo o/n --tag vX [--sign [key]] [--merge f] — pack → GitHub release → entry, in one go.
publish [dir] --repo o/n --tag vX [--sign [key]] [--no-preflight] — the lot: pack → tag + release → preflight → open the PR.
