feat(create): scaffold backend-and-client on the vite-plugin client convention by davidsu · Pull Request #580 · base44/cli

davidsu · 2026-07-29T13:24:10Z

Note

Description

The backend-and-client scaffold now uses the same client wiring that editor-created Base44 apps use, so both app species share one convention. vite.config.js loads @base44/vite-plugin (which supplies the @ alias and the /api dev proxy), the SDK client talks to a same-origin /api (serverUrl: ''), and the app id is no longer baked into scaffolded source — it arrives at run/build time through VITE_BASE44_APP_ID. Scaffolded apps therefore get local entities and functions under base44 dev, and work unchanged against the production backend under base44 dev --remote.

Related Issue

None. Related PRs: #586, #587, #588 — the other three slices of the original unified local-dev rescope, already merged; this PR is the remaining template-convergence slice. The src/lib/app-params.js copy tracks base44-dev/apper#18730.

Changes Made

templates/backend-and-client/vite.config.js — replaced the manual resolve.alias block with the base44() Vite plugin (base44() + react()); the plugin supplies the @ alias and proxies /api to the local dev backend.
templates/backend-and-client/src/lib/app-params.js (new) — reads appId, functionsVersion, and appBaseUrl from import.meta.env, delegates the token to the SDK's getAccessToken(), and honors ?clear_access_token=true by clearing the stored token. Verbatim copy of the upstream apper file.
templates/backend-and-client/src/api/base44Client.js (new, static) — createClient fed from appParams, on same-origin /api (serverUrl: '', requiresAuth: false).
templates/backend-and-client/src/api/base44Client.js.ejs (deleted) — the app id is no longer templated into scaffolded source at create time.
templates/backend-and-client/package.json — bumped @base44/sdk to ^0.8.40 (for the getAccessToken export) and added @base44/vite-plugin ^1.0.30.
cli/commands/project/scaffold-shared.ts — the post-scaffold build now runs with VITE_BASE44_APP_ID set to the new project id, so the first build carries the app id even though it is no longer in source.
core/site/deploy.ts — both missing/empty output-directory hints now point at base44 build (which injects the app id) instead of a bare npm run build.
CHANGELOG.md — added a Changed entry describing the new template convention.

Testing

I have tested these changes locally
I have added/updated tests as needed
All tests pass (npm test)

Added create.spec.ts → "scaffolds backend-and-client with the editor-app client convention", asserting the scaffolded client uses serverUrl: '' and @/lib/app-params and does not hardcode the app id, that app-params.js reads VITE_BASE44_APP_ID / VITE_BASE44_APP_BASE_URL, that vite.config.js references @base44/vite-plugin, and that the app id still lands in base44/.app.jsonc. build, lint, typecheck, and knip are green on CI; the four test-matrix jobs (ubuntu/windows × npm/binary) were still pending when this description was generated, so the "all tests pass" box is left unchecked rather than claimed.

Checklist

My code follows the project's style guidelines
I have performed a self-review of my own code
I have commented my code, particularly in hard-to-understand areas
I have made corresponding changes to the documentation (if applicable)
My changes generate no new warnings
I have updated docs/ (AGENTS.md) if I made architectural changes

Additional Notes

src/lib/app-params.js is a verbatim copy of the upstream apper file and must not diverge from it; if that upstream PR changes in review, re-copy the file here.
New scaffolds now depend on @base44/vite-plugin for the @ alias and the /api proxy. Existing projects are untouched — only newly scaffolded apps lose the hardcoded-appId client.
Because the app id is injected rather than baked in, a bare npm run build in a scaffolded project produces a bundle without an app id; base44 build (or base44 deploy --build) is the supported path, which is why the deploy hints were reworded.
No docs/ update: this changes template contents and one env var passed to a build, not CLI architecture — the CHANGELOG.md entry covers the user-visible behavior.

…44 build, deploy --build The full #580 feature set, rebuilt on top of the decoupled serveCommand runner (#582). dev --remote is now just: resolve the configured serveCommand (or fail), resolve the app's published URL (or fail), run the same runner local dev uses — no backend, no parallel implementation. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…onvention The template adopts the same client wiring editor-created apps use: @base44/vite-plugin (supplies the @ alias and the /api dev proxy) + src/lib/app-params.js (the refactored env-only version from apper#18730, byte-identical) + a static base44Client.js on same-origin /api (serverUrl: ''). The app id leaves scaffolded source: it is injected at serve/build time via VITE_BASE44_APP_ID — by base44 dev, dev --remote, build, and deploy --build — instead of being baked in by create. The post-scaffold build in create/scaffold injects it too, and the missing-build-output hint now points at base44 build. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Mirrors apper fbab06de98f (PR #18730) per Netanel's #580 review: the SDK already defaults requiresAuth to false, so the template stops passing it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
