# hello-web
|
|
|
|
Test frontend for `hello-svc`. Frontend service generated from `nholtware/service-template-react`: a Vite +
|
|
React 19 + React Router (data mode) SPA, served as static files by
|
|
unprivileged nginx.
|
|
|
|
## Develop
|
|
|
|
```sh
|
|
npm install
|
|
npm run dev # http://localhost:5173, /api proxied to API_PROXY_TARGET (default http://localhost:3000)
|
|
npm test
|
|
npm run lint
|
|
npm run format
|
|
```
|
|
|
|
## Runtime config
|
|
|
|
`/config.js` sets `window.__APP_CONFIG__`. In the container,
|
|
`docker-entrypoint.d/10-config.sh` writes it at start from env vars, so one
|
|
image runs in every environment. Read values through `getConfig()` in
|
|
`src/lib/config.ts`.
|
|
|
|
| Env var | Default | Meaning |
|
|
| -------------- | ------- | ----------------------------------------------- |
|
|
| `API_BASE_URL` | `/api` | Backend base URL; `/api` is the same-host route |
|
|
| `APP_NAME` | `app` | Display name |
|
|
|
|
Everything in `config.js` is public. Never put secrets there.
|
|
|
|
## Container
|
|
|
|
- `GIT_SHA` build arg is baked in as `import.meta.env.VITE_GIT_SHA`.
|
|
- nginx listens on 8080: `/healthz` returns 200, unknown paths fall back to
|
|
`index.html`, `/assets/*` are cached as immutable, and `index.html` and
|
|
`config.js` are not cached.
|
|
- Access log: one JSON line per request in the platform logging contract
|
|
(`level`, `time`, `service` = `APP_NAME`, `version` = `GIT_SHA`, `req.id`
|
|
(echoes `X-Request-Id`), `req.method`, `req.url`, `res.statusCode`,
|
|
`responseTime` in ms, `msg: "request completed"`), the same shape as the backend
|
|
template. In Kibana (http://kibana.192.168.1.83.nip.io, data view `kube-*`):
|
|
`service:"hello-web" and res.statusCode >= 400`. `/healthz` isn't logged.
|
|
nginx's own startup/error lines stay plain text (field `log`).
|
|
|
|
## Deploy
|
|
|
|
Push to `main`: Forgejo CI runs lint/test/format, builds and pushes
|
|
`192.168.1.230:3000/nholtware/hello-web:<sha>`, and bumps the tag in the
|
|
gitops repo. ArgoCD then syncs it. Manifests come from gitops
|
|
`templates/frontend/`. The repo needs Actions secrets `REGISTRY_USER`,
|
|
`REGISTRY_TOKEN`, and `GITOPS_TOKEN`.
