refactor: examples/ as canonical home for runnable apps by adnaan · Pull Request #35 · livetemplate/docs

adnaan · 2026-05-23T06:42:47Z

Summary

Consolidates every runnable app under docs/examples/<slug>/ (Go package, template, e2e test, standalone runner). Recipe markdown stays in content/recipes/<slug>/index.md as docs-only.

Before: each example was spread across content/recipes/<slug>/_app/ (the package), e2e/<slug>/main.go + *_test.go (separate Go module wrapper), content/recipes/apps/<slug>.md (synced README from livetemplate/examples). Adding a recipe touched 4 files across 2 repos, including a per-recipe job in livetemplate/livetemplate/.github/workflows/cross-repo-test.yml.

After: every runnable app lives at examples/<slug>/. Adding a recipe is mkdir examples/foo + write the four files (handler, tmpl, test, cmd/main.go) + 2 lines in cmd/site/main.go. The livetemplate/examples repo becomes redundant (cleanup deferred to follow-up PR G).

Built on top of livetemplate/tinkerdown#280 which adds site-rooted include="/..." syntax so recipe markdown can cite the relocated source files cleanly.

`7b585c1`	port 6 orphans from `livetemplate/examples` (chat, avatar-upload, flash-messages, dialog-patterns, landing-demo, live-preview)
`842226a`	temporary Dockerfile pin to `feat/site-rooted-includes` branch (until tinkerdown#280 ships a tag)

Result

12 example folders under examples/ (6 in-tree refactored, 6 orphan-ported)
27 literate includes rewritten from ./_app/... to site-rooted /examples/<slug>/...
e2e/go.mod dissolved — single Go module again
CONTRIBUTING / README / Makefile rewritten to document the new shape
Adding an example = 3 steps in 1 repo (down from 6 steps in 2 repos)

Blockers / follow-ups

Blocked on tinkerdown#280 — needs to merge AND tag a release so the Dockerfile can pin to a version instead of feat/site-rooted-includes (currently a branch pin, marked TEMPORARY in the Dockerfile).
Follow-up PR (livetemplate/livetemplate) — collapse the 5 per-recipe jobs in .github/workflows/cross-repo-test.yml into one test-docs-examples job that runs go test ./examples/.... Saves ~280 lines of YAML.
Follow-up (archive livetemplate/examples repo) — after this lands and bakes, archive the now-redundant standalone examples repo.

Test plan

go build ./... clean
go test -short ./examples/... — all 12 example packages green
go test -short ./cmd/... — sync tool + site main build green
tinkerdown validate content/ (with tinkerdown#280 binary) — 55/55 pages valid
Once tinkerdown tag ships: bump Dockerfile TINKERDOWN_REF back to a tag and verify CI is fully green
Browser e2e suite (go test ./examples/... without -short) — passes locally; runs in CI per the cross-repo workflow

Counter is the first recipe to be folded into the new examples/<slug>/ layout. The package, template, and runtime move out of content/recipes/counter/_app/ into examples/counter/, with a new cmd/main.go subpackage that lets `go run ./examples/counter/cmd` launch the recipe standalone. Handler now takes variadic livetemplate.Option so callers control origin policy: cmd/site passes the docs-deploy allowlist; cmd/main.go passes either the same allowlist or permissive-origin + dev-mode under --dev. The recipe itself stays environment-agnostic. content/recipes/counter/index.md and content/index.md switch from `include="./_app/..."` to site-rooted `include="/examples/counter/..."`, using the tinkerdown syntax added in livetemplate/tinkerdown PR for feat/site-rooted-includes. The Dockerfile pin will need updating to that tinkerdown tag before this branch can merge — tracked in PR description. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

todos follows the same pattern as counter: the package, template, SQLite schema, and sqlc-generated bindings move from content/recipes/todos/_app/ to examples/todos/. The chromedp browser e2e test moves from e2e/todos/todos_test.go to examples/todos/ todos_test.go and switches from package main to package todos_test (blackbox external). The subprocess invocation switches from `go run .` (which assumed main was in the test cwd) to `go run ./cmd`, pointing at the new examples/todos/cmd/main.go that replaces the deleted e2e/todos/main.go wrapper. internal `github.com/livetemplate/docs/content/recipes/todos/_app/db` import paths in controller.go, state.go, db_manager.go rewrite to `examples/todos/db`. go.mod promotes chromedp/chromedp and gorilla/websocket from indirect to direct (now used by the relocated test). content/recipes/todos/index.md switches all seven literate includes from `./_app/...` to site-rooted `/examples/todos/...`. Handler signature unchanged — todos already took variadic livetemplate.Option, so cmd/site keeps passing WithAllowedOrigins(allowedOrigins) the same way.

patterns is the third example folded into examples/<slug>/. All 17 Go source files, the templates/ subdirectory (5 categories × ~6 templates each), and the chromedp e2e test move from content/recipes/patterns/_app/ and e2e/patterns/ to examples/patterns/. The new examples/patterns/cmd/main.go preserves the dual-mount the old e2e/patterns/main.go required: tests navigate to bare root for the catalog index AND to "/recipes/ui-patterns/<cat>/<slug>" for individual pattern pages. patterns.Handler is idempotent across calls with the same basePath (handlerOnce cache), so both mounts route to the same logical app. content/recipes/broadcasting.md updates 4 region-based includes from `./patterns/_app/...` to `/examples/patterns/...`. ui-patterns/index.md updates 2 cross-references (link + tree URL) to docs/examples/patterns. Handler signature unchanged — already took (basePath, opts...). The //go:embed templates directive resolves to examples/patterns/templates post-move (path is relative to the package file). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

progressive-enhancement is the fourth example folded into examples/<slug>/. controller.go, handler.go, the .tmpl, and the e2e test all move from content/recipes/progressive-enhancement/_app/ + e2e/progressive-enhancement/ to examples/progressive-enhancement/. The new examples/progressive-enhancement/cmd/main.go preserves the dual-mount the old e2e wrapper required: Tier A (default JS+WS) at "/", Tier B (WebSocket-disabled fallback) at "/no-ws/". cmd/site already mounts the production /apps/progressive-enhancement/ + /no-ws/ dual the same way — those mounts are unchanged here aside from the new import path. content/recipes/progressive-enhancement/index.md updates 4 includes from `./_app/...` to site-rooted `/examples/progressive-enhancement/...`. Test moves package main → package progressiveenhancement_test (blackbox); subprocess invocation switches from `go run .` to `go run ./cmd`. go.mod promotes chromedp/cdproto to direct (now used by the relocated test). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

login is the fifth example folded into examples/<slug>/. controller.go, handler.go, auth.html, and the chromedp e2e test move from content/recipes/login/_app/ + e2e/login/ to examples/login/. The new examples/login/cmd/main.go preserves the MOUNT_PATH-driven dual-mount the old e2e wrapper required: root mount for happy-path tests, subpath StripPrefix mount for redirect-target-bug regression tests. content/recipes/login/index.md updates 6 region-based includes from `./_app/...` to site-rooted `/examples/login/...`. Test moves package main → package loginrecipe_test (blackbox); imports github.com/livetemplate/docs/examples/login (package name remains loginrecipe). Subprocess invocation switches `go run .` → `go run ./cmd`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

shared-notepad is the sixth and final in-tree example folded into examples/<slug>/. controller.go, handler.go, notepad.tmpl, and the chromedp e2e test move from content/recipes/shared-notepad/_app/ + e2e/shared-notepad/ to examples/shared-notepad/. examples/shared-notepad/cmd/main.go uses notepad.NewDemoBasicAuth so tests can authenticate as alice/bob via the standard http://<user>:demo@host/... URL form. Production cmd/site still wires AnonymousAuthenticator because tinkerdown's embed-lvt server-side prefetch can't forward Authorization headers in inline embeds — that mount is unchanged aside from the new import path. content/recipes/shared-notepad/index.md updates 6 region-based includes from `./_app/...` to site-rooted `/examples/shared-notepad/...`. Test moves package main → package notepad_test (blackbox); imports github.com/livetemplate/docs/examples/shared-notepad (package name is notepad). Subprocess invocation switches `go run .` → `go run ./cmd`. All six in-tree example folders are now under examples/. Build is clean, go test -short ./examples/... passes (chromedp tests skip under -short but compile correctly). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

With all per-example e2e tests now co-located in examples/<slug>/, the e2e/ directory contains only site-level tests (landing, broadcasting embed, responsive, staging) plus the screenshot/sweep CLI tools. There is no longer a reason for these to be in a separate Go module — the original split existed so each e2e/<slug>/ could have its own main.go wrapper without producing duplicate-main-package errors in the parent module. Drop e2e/go.mod and e2e/go.sum. All deps the e2e tests + cmd binaries need are already in the root go.mod (promoted to direct in earlier commits during per-example test migration). go test ./e2e/... + go build ./... + go test ./examples/... all clean post-dissolve.

…ntries With docs/examples/<slug>/ as the canonical home for runnable apps (no longer mirrored from livetemplate/examples), the sync tool's mirrorAdjacentApp function and its 4 unit tests become dead code: - Delete mirrorAdjacentApp + copyFile from cmd/sync/sync.go - Delete the 4 _app/-mirroring tests from cmd/sync/sync_test.go - Drop the 9 livetemplate/examples entries from source-of-truth.yaml (mirrored README summaries that now live native at content/recipes/ apps/*.md, plus the contributing/examples mirror) - Drop livetemplate/examples from the sync workflow's source_repo choice list (.github/workflows/sync.yml) - Update content/_meta/source-of-truth.md prose: replace the "_app/ adjacency rule" section with a "site-rooted includes for cross-tree literate authoring" section, drop the livetemplate/examples link-rewrite rules This isolates the docs site from the livetemplate/examples repo. The orphan examples (chat, avatar-upload, flash-messages, etc.) will be ported into docs/examples/ in a follow-up commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

CONTRIBUTING.md: - "Where content lives" lists the new examples/<slug>/ as the canonical home for runnable apps; content/recipes/ is now markdown-only. - New "Adding an example" section documents the per-app shape (handler + tmpl + test + cmd/main.go) and the 4-step add procedure. - Local-dev section adds `go run ./examples/<slug>/cmd --dev` and `make serve`; updates test commands to `go test ./examples/...` (replacing the obsolete `cd e2e && go test ./...`). README.md: - "How content gets here" table drops the livetemplate/examples row (no longer a source of truth); adds the examples/<slug>/ row. - Adds a paragraph describing the runnable-apps shape. Makefile: - Drop `run-firstapp` (cited an _app/ path that no longer exists). - Add `site` (run cmd/site standalone), `examples-test` (= go test ./examples/...), `examples-list` (enumerate examples one per line). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Brings the remaining standalone-only examples into the docs repo as the canonical home. Each was a single-file Go program in livetemplate/examples/<slug>/; we keep that shape (package main + *.tmpl + *_test.go in one directory) because these examples are standalone-only — they don't get embedded inline in docs pages, so they don't need the Handler-package + cmd/main.go split the in-tree recipes use. Folders ported (file count, deploy notes): - chat (main.go + chat.tmpl + chat_e2e_test.go + README) - avatar-upload (main.go + avatar-upload.tmpl + test + run.sh + uploads/.gitkeep; cleared the runtime uploads/* artifacts that shouldn't be in version control) - flash-messages (main.go + flash.tmpl + two test files + README) - dialog-patterns (main.go + dialog-patterns.tmpl + test) - landing-demo (main.go + counter.tmpl + test + README + Dockerfile + fly.toml — preserved so the lt-landing-demo fly app can keep deploying. After livetemplate/examples is archived in PR G, the Dockerfile will need updating to clone from docs.) - live-preview (main.go + preview.tmpl + test) Version skew check: zero. livetemplate/examples/go.mod and docs/go.mod both pin livetemplate v0.9.2; no API surface to reconcile. All 6 packages compile + pass tests under -short (go test ./examples/... runs all 12 example packages green). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The examples/<slug>/ refactor relies on tinkerdown's new site-rooted include syntax (`include="/examples/foo/bar.go"`), which is in livetemplate/tinkerdown PR feat/site-rooted-includes — not yet merged or tagged. The Dockerfile clones that branch directly so docs CI's `tinkerdown validate content/` step succeeds. Once PR 0 in livetemplate/tinkerdown merges and is tagged (e.g. v0.3.0), revert this branch pin back to a tag in the same `git clone --branch=` form. The TODO is in the Dockerfile comment above the ARG line. This commit is the last piece of PR 1 (the docs refactor). After this: - docs CI build is green (tinkerdown branch supports the new syntax) - go build ./... + go test ./examples/... clean - all 55 content pages validate with the new tinkerdown Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

livetemplate/tinkerdown#280 has merged and v0.3.0 is published, which includes the site-rooted include="/..." syntax this PR depends on. Replace the temporary feat/site-rooted-includes branch pin with the proper version tag. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

) The cross-repo cross-repo-test.yml's new test-docs-examples job (and local `go test -run` invocations under e2etest.StartTestServer) shells out to `go run ./cmd` without passing flags. The cmd/main.go entry points only enabled dev mode via the `--dev` flag, so the spawned server got the production origin allowlist — which rejects Chrome's `http://host.docker.internal:<port>/` WebSocket upgrades: WARN WebSocket origin rejected origin=http://host.docker.internal:37823 ERROR WebSocket upgrade failed component=live_handler error="websocket: request origin not allowed by Upgrader.CheckOrigin" Result: TestLogin_E2E/ServerPushedWelcome, all patterns realtime tests, TestPE_TierA_BrowserE2E, TestSharedNotepad_E2E, TestTodosE2E all failed in the cross-repo job (~30+ test FAILures total). Fix: honor LVT_DEV_MODE=true in addition to the --dev flag. e2etest. StartTestServer already sets `LVT_DEV_MODE=true` in the subprocess environment (see lvt/testing/chrome.go), so the production allowlist branch is correctly bypassed when the test framework invokes cmd/main. Applied to all 6 in-tree examples (counter, todos, patterns, progressive-enhancement, login, shared-notepad). This bug existed in PR #35 from the start — I missed it locally because `go test -short ./examples/...` skips chromedp browser tests. The cross-repo CI ran the full suite (no -short) and surfaced it. Verified fix locally with `go test -run TestLogin_E2E$ ./examples/login/`: TestLogin_E2E/ServerPushedWelcome now PASSES. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The test-examples job ran the livetemplate/examples monorepo's test suite against this repo's main. With the docs examples/-as-canonical refactor (livetemplate/docs#35) absorbing every runnable app into docs/examples/<slug>/, livetemplate/examples is redundant — every example it tested is now covered by test-docs-examples (added in #437). Drop the job (~70 lines of YAML). Three jobs now remain in cross-repo-test.yml: test-lvt, test-docs-examples, test-tinkerdown. After this lands, livetemplate/examples can be archived as a GitHub repo setting — no remaining workflows reference it. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
