Fusion Developer Portal

Fusion Developer Portal

Guide development of Fusion portal shells — host applications that load, route, and render Fusion apps inside shared chrome (header, context selector, navigation).

When to use

• Scaffold new Fusion portal
• portal.manifest.ts or ffc portal dev questions
• Configure portal-level modules (telemetry, analytics, navigation, services, app module)
• Build custom app loader or portal shell
• Add portal-level routing (/apps/:appKey/*)
• Apploader component or useApploader hook for embedding apps
• Wire up portal header, context selector, or bookmark side sheet
• Understand how portals load/initialize Fusion apps at runtime
• Add portal-level analytics or telemetry
• Portal deployment (ffc portal build, ffc portal upload)

When not to use

• App-level feature development → fusion-app-react-dev
• Backend service changes → separate repo
• Fusion Help Center integration → fusion-help-integration
• Skill authoring → fusion-skill-authoring
• Issue authoring → fusion-issue-authoring

Required inputs

Mandatory

• What to build: scaffold a portal, add a feature, configure a module, or understand portal architecture
• Portal context: new from scratch or modifying existing

Conditional

• Portal name/ID when scaffolding
• MSAL client ID and service discovery URL when configuring auth
• Specific modules to enable (analytics, telemetry, bookmarks, feature flags, AG Grid)
• Whether the portal needs a custom app loader or the default Apploader suffices

Instructions

Step 1 — Classify the portal task

Determine what the user needs:

• Scaffold new portal → step 2
• Configure portal modules → step 3
• App loading and routing → step 4
• Portal chrome (header, context, bookmarks) → step 5
• Analytics and telemetry → step 6
• Build and deploy → step 7

When Fusion MCP is available, prefer mcp_fusion_search_framework with queries like "portal manifest definePortalManifest ffc portal" or "createFrameworkProvider PortalModuleInitiator portal configure" for latest API surface. Label guidance not confirmed by MCP as fallback.

Step 2 — Scaffold a new portal

Use the Fusion Framework CLI:

mkdir my-fusion-portal && cd my-fusion-portalpnpm initpnpm add -D @equinor/fusion-framework-cli

Create the required files:

• portal.manifest.ts — portal metadata and configuration:

import { definePortalManifest } from '@equinor/fusion-framework-cli/portal';
export default definePortalManifest((env, { base }) => ({  name: 'my-portal',  version: '1.0.0',  entry: './src/index.tsx',}));

• portal.schema.ts (optional) — configuration validation schema
• src/index.tsx — portal entry point (see references/portal-architecture.md [blocked])

Start the dev server:

pnpm fusion-framework-cli portal dev# or: ffc portal dev

Step 3 — Configure portal modules

Portal-level configuration uses FrameworkConfigurator (not AppModuleInitiator like apps). Enable modules in your configure callback:

import type { FrameworkConfigurator } from '@equinor/fusion-framework';import { enableAppModule } from '@equinor/fusion-framework-module-app';import { enableNavigation } from '@equinor/fusion-framework-module-navigation';import { enableAnalytics } from '@equinor/fusion-framework-module-analytics';
const configure = (configurator: FrameworkConfigurator) => {  enableAppModule(configurator);  enableNavigation(configurator, '/');  enableAnalytics(configurator, { /* ... */ });};

Key difference from app configuration: the portal configures FrameworkConfigurator and its modules are hoisted to all child apps. MSAL/auth is configured at portal level and inherited by apps.

See references/portal-architecture.md [blocked] for full module configuration and portal-analytics cookbook reference.

Step 4 — App loading and routing

The portal routes /apps/:appKey/* to an app loader. Two approaches:

Simple embed — use the built-in Apploader component:

import { Apploader } from '@equinor/fusion-framework-react-app/apploader';
<Apploader appKey="my-app" />

Warning: Apploader is an experimental POC. Embedded apps may have routing and context issues. Best for simple apps like PowerBI or PowerApps views.

Custom app loader — for full control over loading states, error handling, and mounting. Use useFramework<[AppModule]>(), observe fusion.modules.app.current$, and call app.initialize(). See references/portal-architecture.md [blocked] for the annotated custom AppLoader pattern.

Portal routing typically uses react-router-dom via the navigation module:

const Router = () => {  const framework = useFramework();  const router = framework.modules.navigation.router;  return <RouterProvider router={router} />;};

Step 5 — Portal chrome

Portal-level UI typically includes:

• Header — top bar with Fusion logo, context selector, bookmarks, person settings
• Context selector — wired to app context module via useCurrentContext or useContextSelector
• Bookmark side sheet — toggled via navigation module
• App navigation — sidebar or top-level nav for switching apps

Apps don't build their own header — they receive it from the portal shell.

Step 6 — Analytics and telemetry

Portal-level analytics capture app lifecycle events. Enable with adapters and collectors:

import { enableAnalytics } from '@equinor/fusion-framework-module-analytics';import { ConsoleAnalyticsAdapter } from '@equinor/fusion-framework-module-analytics/adapters';import { AppLoadedCollector, AppSelectedCollector } from '@equinor/fusion-framework-module-analytics/collectors';
enableAnalytics(configurator, (builder) => {  builder.addAdapter(new ConsoleAnalyticsAdapter());  builder.addCollector(new AppLoadedCollector());  builder.addCollector(new AppSelectedCollector());});

For telemetry (OpenTelemetry / Application Insights), see references/portal-architecture.md [blocked].

Step 7 — Build and deploy

# Build the portal templateffc portal build
# Upload to the Fusion portal service (authenticate via `az login` or FUSION_TOKEN env var)ffc portal upload --portal-id <id>
# Tag a specific versionffc portal tag --portal-id <id> --tag latest --version <version>

Never paste tokens directly into commands. Use az login for interactive auth or set FUSION_TOKEN env var for CI pipelines.

Step 8 — Validate

1. ffc portal dev starts without errors
2. Apps load at /apps/:appKey
3. Context selector and header render properly
4. TypeScript compiles with no errors
5. Analytics events fire on app load/select (if enabled)

Expected output

• Working portal shell with app loading, routing, and chrome
• Portal-level module configuration with correct FrameworkConfigurator usage
• Loading and error states handled for app initialization
• Brief summary of what was created or changed

Helper agents

Same companion infrastructure as fusion-app-react-dev:

• fusion-research — source-backed Fusion ecosystem research when portal behavior is uncertain
• fusion-code-conventions — naming, TSDoc, and code style checks

When Fusion MCP is available, prefer mcp_fusion_search_framework for portal-specific lookups.

Safety & constraints

• MSAL is portal-level — never configure auth in apps; it is hoisted from the portal
• Don't invent portal APIs — only reference APIs confirmed by MCP or documented in references
• Apploader is experimental — always mention routing/context limitations when advising on app embedding
• No secrets in source — MSAL client IDs must come from environment variables, not hardcoded
• Don't modify the production Fusion portal — this skill covers custom portal development only
• Conventional commits for all changes
