5aae2a0d16Cross-origin WASM CDN (cdn.pcbjam.com, R2): per-tool content-addressed, immutable folders + a per-release runtime manifest (snapshot from registry). boot.ts loads pthread workers cross-origin via a same-origin blob shim. Static no-backend project source (demo gallery; Save downloads to local), api.uploadFileBytes kept and config-gated. demo.pcbjam.com on Cloudflare Pages. deploy-demo.yml (tag v*) snapshots WASM + content + builds + deploys; publish-wasm.yml builds on Ubicloud. Design/spec docs live in pcbjam-private. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# demo.pcbjam.com deploy runbook
|
|
|
|
The no-backend demo: the GPL standalone on **Cloudflare Pages** (`demo.pcbjam.com`),
|
|
its WASM + example projects on a versioned **R2 CDN** (`cdn.pcbjam.com`). The
|
|
design/spec docs live in the private `pcbjam-private` repo
|
|
(`docs/features/demo-deploy/`).
|
|
|
|
```
|
|
git tag vX.Y.Z ──▶ .github/workflows/deploy-demo.yml
|
|
1. snapshot current WASM → cdn/wasm/manifest-<tag>.json (reuse prebuilt)
|
|
2. publish example gallery → cdn/content/<tag>/
|
|
3. build standalone (pinned to CDN + tag) → dist/
|
|
4. wrangler pages deploy → demo.pcbjam.com
|
|
|
|
(separately, only when the WASM changes) publish-wasm.yml (Ubicloud) / local seed
|
|
build WASM → cdn/wasm/<tool>/<ver>/ + registry.json
|
|
```
|
|
|
|
Everything here lives in the GPL `pcbjam` repo (the demo *is* the GPL standalone;
|
|
no closed code), so `publish-wasm.yml` reuses the existing Ubicloud build infra.
|
|
|
|
## One-time setup (Cloudflare — needs your account)
|
|
|
|
1. `pcbjam.com` zone on Cloudflare; note the **account id**.
|
|
2. Public bucket: `wrangler r2 bucket create pcbjam-cdn`.
|
|
3. Custom domain `cdn.pcbjam.com` → the `pcbjam-cdn` bucket (R2 → Settings → Custom Domains).
|
|
4. **Transform Rule** on `cdn.pcbjam.com` (Rules → Transform Rules → Modify Response Header),
|
|
"set static" on all requests:
|
|
- `Cross-Origin-Resource-Policy: cross-origin`
|
|
- `Access-Control-Allow-Origin: *`
|
|
(R2 can't set CORP as object metadata; the demo page is COEP `require-corp`.)
|
|
5. Cloudflare Pages project `pcbjam-demo`; custom domain `demo.pcbjam.com`.
|
|
6. API token (Workers/Pages: Edit, R2: Edit) → this repo's GitHub secrets
|
|
`CLOUDFLARE_API_TOKEN` + `CLOUDFLARE_ACCOUNT_ID`.
|
|
|
|
## First-time WASM seed (local — run from the pcbjam repo root; `output/` is already built)
|
|
|
|
```sh
|
|
wrangler login # or export CLOUDFLARE_API_TOKEN + _ACCOUNT_ID
|
|
node scripts/deploy/publish-wasm.mjs --tag kicad-9.0.1 \
|
|
--src output --driver r2 --bucket pcbjam-cdn --remote
|
|
```
|
|
|
|
This uploads per-tool content-addressed folders + `registry.json`. Re-runs are
|
|
idempotent (unchanged tools are skipped). `--tag` names the folder of any tool
|
|
whose bytes changed; pick something readable (the KiCad version works well).
|
|
|
|
> Preview the exact upload offline first with `--driver local --out /tmp/cdn`
|
|
> (writes the bucket layout + a `_uploads.json` of every object's HTTP metadata).
|
|
|
|
## Deploying the demo
|
|
|
|
Tag a release — `git tag v1.2.3 && git push --tags` — and `deploy-demo.yml` runs.
|
|
Or trigger it manually (Actions → deploy-demo → Run, with a tag). It does **not**
|
|
rebuild WASM; it snapshots whatever `publish-wasm` last published, so returning
|
|
users don't re-download the (large) WASM on releases that didn't change it.
|
|
|
|
Roll a bad tool back without redeploying the app: edit
|
|
`cdn/wasm/manifest-<tag>.json` to point the tool at an older `<ver>` (still in the
|
|
bucket); it's served uncached, so the next load picks it up.
|
|
|
|
## When the WASM changes
|
|
|
|
Run `publish-wasm.yml` (Actions → publish-wasm → Run, with a `wasm_tag`) — it
|
|
builds on Ubicloud (sharing ci-ubicloud's deps cache) and publishes — or re-run
|
|
the local seed with a new `--tag`. Then deploy a release as usual; the snapshot
|
|
picks up the new versions.
|
|
|
|
## Add example projects to the gallery
|
|
|
|
Edit [`gallery.json`](gallery.json) (references source files in the repo; no
|
|
copies). Preview: `node scripts/deploy/publish-content.mjs --tag t --driver local
|
|
--out /tmp/cdn`.
