Modern Angular component patterns used throughout this workspace — signals, input()/output() functions, @if/@for control flow, OnPush, and standalone imports. Use when creating or editing any component, directive, pipe or template, and when a lint rule rejects @Input, *ngIf or CommonModule.
Create a complete feature library in libs/ — generator command, folder layout, tags, routes, store and barrel exports. Use when adding a new feature to the workspace, or when unsure where a new page, service or component belongs. libs/profile is the async reference, libs/settings the synchronous one.
Log analytics events through the vendor-neutral ANALYTICS token. Use when adding tracking to a component or service, when wiring an analytics implementation in app.config.ts, or when replacing or removing Firebase analytics.
Wire a route so its feature is genuinely lazy-loaded. Use when adding a route with loadChildren or loadComponent, when deciding what a library barrel may export, or when a lazy chunk turns out to be bundled eagerly.
Nx tags and the ESLint depConstraints that enforce them. Use when creating a library, choosing or registering a scope: tag, or fixing an @nx/enforce-module-boundaries lint error. A tag with no depConstraints entry is unconstrained, which silently defeats the rules.
Feature state with NgRx SignalStore — withState, withComputed, withMethods, withHooks, rxMethod, and providing the store on its route. Use when adding state to a feature, writing or changing a store, or migrating off the classic NgRx Store.

This project includes a ready-to-use Firebase Hosting setup for deploying the Angular app as a SPA. Follow this guide every time you set up or deploy to a new Firebase project.
Setting up a Firebase project for the first time?
hosting/README.mdcovers the console side click by click, with screenshots. This page is the reference for the repo side: scripts, configuration and CI.
The deploy pipeline has three steps that always run in order:
dist/apps/demo-app/browser/dist/ folder is copied into hosting/, making it available to Firebase CLIhosting/ and uploads the built filesproject root
├── dist/apps/demo-app/browser/ ← Angular build output
└── hosting/
├── .firebaserc ← Firebase project binding
├── firebase.json ← Hosting configuration
└── dist/ ← Created at deploy time (gitignored)
└── apps/demo-app/browser/
The firebase.json is located inside hosting/ and its public path is relative to that directory, which is why the copy step is needed before deploying.
Install the Firebase CLI globally if not already installed:
npm install -g firebase-tools
Authenticate:
firebase login
config/firebase.jsonDo not edit hosting/.firebaserc or the environment*.ts files. Both the deploy
target and the app's Firebase config are generated from one JSON file, so there is a
single place to fill in — and no credential ever reaches a tracked file.
cp config/firebase.example.json config/firebase.json
Open Firebase Console → Project settings → General → Your apps → SDK setup and configuration → Config, and paste the object into that file:
{
"apiKey": "AIzaSy...",
"authDomain": "my-firebase-project.firebaseapp.com",
"projectId": "my-firebase-project",
"storageBucket": "my-firebase-project.firebasestorage.app",
"messagingSenderId": "123456789",
"appId": "1:123456789:web:abc123",
"measurementId": "G-ABCDEF1234"
}
The console shows JavaScript, not JSON. Paste it as copied anyway — unquoted keys,
single quotes, trailing commas, // comments and a leading const firebaseConfig = are
all normalised by the reader. For byte-exact JSON instead:
firebase apps:sdkconfig web --project <id> --json.
tools/generate-config.mjs then writes, on npm install and before every Nx
build/serve/test:
| Generated file | Purpose | Tracked |
|---|---|---|
libs/environment/src/lib/generated/firebase.config.ts | what the app compiles against | no |
hosting/.firebaserc | project + site the CLI deploys to | no |
Force a regeneration with npm run config:generate.
Set FIREBASE_HOSTING_SITE in .env only when the Hosting site id differs from the
project id (extra sites created under Console → Hosting). It defaults to the project id.
Deploying from CI: skip the config file entirely and export the values as real
environment variables — FIREBASE_API_KEY, FIREBASE_PROJECT_ID, FIREBASE_APP_ID,
FIREBASE_MESSAGING_SENDER_ID, FIREBASE_MEASUREMENT_ID. They take precedence over the
file, so GitHub Actions secrets work with no extra wiring.
A Firebase web config is not a secret — it ships inside the client bundle of every Firebase app, and access is governed by Security Rules and API key restrictions. It lives in
config/so that a clone of this template never reports into your project, and so you edit one file instead of three.
| Script | Command | What it does |
|---|---|---|
build:deploy:firebase | Full pipeline | Build → copy dist → deploy |
utils:copy:dist | Copy only | Copies ./dist into ./hosting/ |
deploy:firebase | Deploy only | Runs firebase deploy from ./hosting/ |
Full pipeline (most common):
npm run build:deploy:firebase
Deploy only (if the app is already built and dist is already copied):
npm run deploy:firebase
hosting/firebase.json is pre-configured for Angular SPA deployments:
/index.html — required for Angular client-side routingindex.html is served with no-cache headers so users always get the latest version{
"hosting": [
{
"target": "app",
"public": "dist/apps/demo-app/browser",
"rewrites": [{ "source": "**", "destination": "/index.html" }],
"headers": [
{
"source": "index.html",
"headers": [
{
"key": "Cache-Control",
"value": "no-cache, no-store, must-revalidate"
}
]
},
{
"source": "**/*.@(js|css|json|ico|png|jpg|jpeg|svg|ttf|woff|woff2|eot)",
"headers": [
{ "key": "Cache-Control", "value": "public, max-age=31536000" }
]
}
]
}
]
}
Do not change the public path — it must match the Angular build output path defined in apps/demo-app/project.json.
If the monorepo grows to include a second app (e.g., apps/admin), add a second hosting target in firebase.json:
{
"hosting": [
{
"target": "app",
"public": "dist/apps/demo-app/browser",
"rewrites": [{ "source": "**", "destination": "/index.html" }]
},
{
"target": "admin",
"public": "dist/apps/admin/browser",
"rewrites": [{ "source": "**", "destination": "/index.html" }]
}
]
}
The second target also has to be registered in .firebaserc — which is generated, so
teach the generator about it rather than editing the output. In
tools/generate-config.mjs, extend writeFirebaseRc:
targets: { [project]: { hosting: { app: [site], admin: [`${project}-admin`] } } },
Editing hosting/.firebaserc by hand works until the next build, which overwrites it.
Two workflows ship with the template:
| Workflow | Trigger | Result |
|---|---|---|
.github/workflows/deploy.yml | push to main, or manual | Deploys to the live channel — https://<project-id>.web.app |
.github/workflows/preview.yml | every pull request | Deploys a preview channel, comments the URL on the PR, expires after 7 days, then runs the Playwright suite against it |
Settings → Secrets and variables → Actions → New repository secret.
| Secret | Value | Actually secret? |
|---|---|---|
FIREBASE_SERVICE_ACCOUNT | The full JSON key of a service account | Yes. This one grants deploy access. |
FIREBASE_PROJECT_ID | e.g. base-angular-monorepo | No |
FIREBASE_API_KEY | AIzaSy… | No |
FIREBASE_AUTH_DOMAIN | <project-id>.firebaseapp.com | No |
FIREBASE_STORAGE_BUCKET | <project-id>.firebasestorage.app | No |
FIREBASE_MESSAGING_SENDER_ID | numeric | No |
FIREBASE_APP_ID | 1:…:web:… | No |
FIREBASE_MEASUREMENT_ID | G-… | No |
Only the first one is a credential. The rest are stored as secrets so a fork
never builds with this project's identity and starts reporting analytics into it —
they are shipped publicly in the bundle regardless. tools/generate-config.mjs
reads each of them from the environment, which is why CI needs no config/ file.
To create the service account:
firebase init hosting:github # generates the key and sets the secret for you
or, by hand: Google Cloud Console → IAM & Admin → Service Accounts → create one
with Firebase Hosting Admin, add a JSON key, and paste the whole file into
FIREBASE_SERVICE_ACCOUNT.
Do not use
firebase login:citokens. They are long-lived, carry your full user permissions, and cannot be scoped.
The same GitHub settings page offers Secrets and Variables. They are
different contexts — secrets.FOO and vars.FOO — and a value put in the wrong
one reads as empty in the other. That is what produces:
Error: Input required and not supplied: firebaseServiceAccount
The distinction matters beyond the workflow failing. Variables are stored in plain text, are not masked in logs, and are readable in the UI by anyone with repository access. A service account key placed there must be treated as leaked: delete the key in Google Cloud Console (Service Accounts → the account → Keys), then issue a new one. Removing it from GitHub does not revoke it.
The Check deploy credentials step at the top of both workflows exists to catch
this in seconds rather than after a full build.
The config in the bundle is public. That is by design, and the protection lives elsewhere — do all four of these once the site is live.
1. Restrict the API key to your domains. Google Cloud Console → APIs & Services → Credentials → the Browser key (auto created by Firebase) → Application restrictions → HTTP referrers:
https://<project-id>.web.app/*
https://<project-id>.firebaseapp.com/*
https://<project-id>--*.web.app/* ← preview channels
http://localhost:4200/*
Under API restrictions, limit it to what the app actually calls — for an analytics-only setup that is the Firebase Installations API and Google Analytics. Anything else is surface you are not using.
2. Turn on App Check. Console → App Check → register the web app with reCAPTCHA Enterprise, then enforce it per service. This is the real answer to "someone copied my apiKey": it attests that a request came from your app, and a copied key on another origin fails attestation.
3. Write Security Rules before enabling Firestore, Storage or Realtime Database. The default rules in test mode are open to the internet and expire silently. This template uses none of those services, so there is nothing to write yet — the moment you add one, this becomes the most important item on the list.
4. Set a budget alert. Google Cloud Console → Billing → Budgets & alerts. Abuse of a public endpoint shows up as a bill.
Anything that grants access on its own: service account keys, an LLM provider's API key, a database password, a private third-party token. No amount of build-time substitution makes these safe — the bundle is readable. They belong behind a Cloud Function or Cloud Run service that holds them in Secret Manager, and the frontend calls that.
