Fusebase CLI

Fusebase CLI (fusebase)

This skill describes how to use the Fusebase CLI tool to manage and deploy Fusebase Apps features.

Overview

The Fusebase CLI (fusebase) is a command-line tool for:

• Initializing new Fusebase Apps projects
• Managing feature development with hot reload
• Deploying features to the Fusebase platform

Installation & Authentication

The fusebase CLI is installed globally. Always invoke it as fusebase <command> — never use npx fusebase.

Before using the CLI, authenticate with your API key:

fusebase auth

This stores credentials in ~/.fusebase/config.json.

Project Configuration (fusebase.json)

Every Fusebase Apps project requires a fusebase.json file in the project root. This file defines the app and its features.

For details on the fusebase.json schema, see references/fusebase-json-schema.md.

Feature Permissions

Features can have permissions that define which dashboard views they can access. This is required when creating features that interact with specific dashboards.

Permission Format

Permissions are specified as a semicolon-separated string:

dashboardView.dashboardId:viewId.privileges[;dashboardView.dashboardId2:viewId2.privileges2;...]

Where:

• dashboardView - The permission type (currently only dashboardView is supported)
• dashboardId - The dashboard's global ID (UUID from MCP or Fusebase UI)
• viewId - The view's global ID (UUID from MCP or Fusebase UI)
• privileges - Comma-separated: read, write, or read,write

Setting Permissions

Always set permissions during feature creation using --permissions. This is the correct time — do not skip it and do feature update later.

fusebase feature create --name="Sales Report" --subdomain=sales-report --path=features/sales-report --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist --permissions="dashboardView.dash123:view456.read,write"

Only use feature update when changing existing permissions (e.g. adding a new view, changing privileges):

fusebase feature update <featureId> --permissions="dashboardView.dash123:view456.read;dashboardView.dash789:viewABC.read,write"

When to Use feature update for Permissions

Only use feature update --permissions when:

• Feature already exists and needs access to additional dashboard views
• Changing from read-only to read-write (or vice versa) on an existing feature
• Restricting access to fewer views on an existing feature

Do NOT use feature update to set permissions that should have been set at creation time.

CLI Commands

Version

fusebase version   # Print CLI version (from package.json)
fusebase -V        # Same

Initialize a New Project

fusebase init [options]

Options:

• --name <name> - App title/name (if not provided, will prompt interactively)
• --org <orgId> - Organization ID (skips org selection if provided)
• --ide <preset> - IDE preset: claude-code, cursor, vscode, opencode, codex, or other (single choice; generates all supported IDE configs by default)
• --force - Overwrite existing IDE config files/folders
• --git - After setup, offer to initialize a local Git repository (local only until you add a git remote and push)
• Global flag git-init also enables the same post-init Git offer automatically (fusebase config set-flag git-init)
• Global flag git-debug-commits enables strict debug/deploy traceability section in the git-workflow skill (deploy preflight, commit-per-fix, SHA/tag references)

This command always creates a new app on Fusebase and initializes the project. It will:

• Prompt for organization selection (or use --org if provided)
• Create a new app with the specified name
• Generate fusebase.json configuration
• Set up the basic project structure with template files

If the current directory is not empty and you decline the confirmation prompt, initialization stops without creating the app or local config.

Examples:

# Initialize interactively (prompts for all values)
fusebase init

# Initialize with app name specified
fusebase init --name="My App"

# Initialize with all options (fully non-interactive, assumes single org)
fusebase init --name="My App" --org=org_abc123

Local Git (optional)

fusebase git

Runs git init in the current directory. This is local version control only — nothing is uploaded until you add a remote (e.g. GitHub/GitLab) and git push. If Git is missing, the CLI points to the official install page and asks you to run fusebase git again afterward.

Use fusebase init --git to be prompted whether to initialize Git after app setup.

Development Mode

Start the Dev Server

fusebase dev start [FEATURE_ID_OR_PATH]

FEATURE_ID_OR_PATH - id of the feature of relative path to it, for example if a feature is in features/my-feature, you can pass my-feature or features/my-feature.

Starts the development environment:

• UI Server (port 4173): Displays features in iframes for testing
• API Proxy (port 4174): Proxies API requests with authentication

The dev server automatically:

• Injects your API credentials
• Delivers feature tokens to iframes via postMessage
• Refreshes tokens when features are selected
• Creates per-session debug logs under the selected feature directory's logs/dev-<timestamp>/:
  • browser-logs.jsonl
  • access-logs.jsonl
  • backend-logs.jsonl
  • frontend-dev-server-logs.jsonl

When debugging local runtime issues after starting the dev server, load skill dev-debug-logs. It explains which file to inspect for browser errors, proxied API traffic, frontend dev server output, and backend output.

Create and Configure Feature

fusebase feature create --name <name> --subdomain <subdomain> --path <path> --dev-command <command> --build-command <command> --output-dir <dir> [options]

This command always creates a new feature on Fusebase servers and configures its development parameters. All six core options are required.

Required Options:

• --name <name> - Name for the new feature
• --subdomain <subdomain> - Subdomain for the feature (e.g., my-feature); the feature is served from the root of this subdomain
• --path <path> - Relative path to the feature directory (e.g., features/my-feature)
• --dev-command <command> - Dev server command (e.g., npm run dev)
• --build-command <command> - Build command (e.g., npm run build)
• --output-dir <dir> - Build output directory (e.g., dist)

Optional Options:

• --access <principals> - Set access principals, comma-separated (e.g., visitor, orgRole:member, visitor,orgRole:guest)
• --permissions <permissions> - Set dashboard view permissions (format: dashboardView.dashboardId:viewId.read,write;...)
• --backend-dev-command <command> - Backend dev command (e.g., npm run dev). Only if the feature has a backend/ folder.
• --backend-build-command <command> - Backend build command (e.g., npm run build). Only if the feature has a backend/ folder.
• --backend-start-command <command> - Backend start command for production (e.g., npm run start). Only if the feature has a backend/ folder.

Examples:

# Create a feature
fusebase feature create --name="Dashboard Widget" --subdomain=dashboard-widget --path=features/dashboard --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist

# Create feature with permissions for specific dashboard views
fusebase feature create --name="Sales Report" --subdomain=sales-report --path=features/sales-report --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist --permissions="dashboardView.dash123:view456.read,write;dashboardView.dash789:viewABC.read"

# Create feature with a backend
fusebase feature create --name="My App" --subdomain=my-app --path=features/my-app --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist --backend-dev-command="npm run dev" --backend-build-command="npm run build" --backend-start-command="npm run start"

Update Feature Settings

fusebase feature update <featureId> [options]

Update settings for an existing feature.

Options:

• --access <principals> - Set access principals, comma-separated (e.g., visitor, orgRole:member, visitor,orgRole:guest)
• --permissions <permissions> - Set dashboard view permissions (format: dashboardView.dashboardId:viewId.read,write;...)
• --sync-gate-permissions - Analyze Gate SDK calls in the feature's runtime code and sync the detected operations as Gate permissions on the feature. Required before a feature that uses @fusebase/fusebase-gate-sdk can be considered fully published.

Access Principals:

The --access option replaces the entire access principal list. Principals are comma-separated entries of the form type or type:id:

Permissions: The --permissions option specifies which dashboard views the feature can access and with what privileges.

Format: dashboardView.dashboardId:viewId.privileges separated by semicolons for multiple views.

• dashboardView - The permission type (required prefix)
• dashboardId - The dashboard's global ID (UUID)
• viewId - The view's global ID (UUID)
• privileges - Comma-separated list: read, write, or read,write

Examples:

# Make a feature publicly accessible (visitor = any unauthenticated user)
fusebase feature update аgjg851jguanadi41 --access=visitor

# Allow org members only
fusebase feature update аgjg851jguanadi41 --access=orgRole:member

# Allow multiple roles
fusebase feature update аgjg851jguanadi41 --access=orgRole:member,orgRole:client

# Public + org members
fusebase feature update аgjg851jguanadi41 --access=visitor,orgRole:member

# Remove all access principals (pass empty string), it will allow access for every role in organization, but not for visitors
fusebase feature update аgjg851jguanadi41 --access=""

# Grant read access to a single dashboard view
fusebase feature update аgjg851jguanadi41 --permissions="dashboardView.dashABC:view123.read"

# Grant read/write access to multiple views
fusebase feature update аgjg851jguanadi41 --permissions="dashboardView.dash1:view1.read,write;dashboardView.dash2:view2.read"

# Update both access and permissions
fusebase feature update аgjg851jguanadi41 --access=visitor --permissions="dashboardView.dash1:view1.read"

Update AGENTS.md and Skills

fusebase skills update

Overwrites AGENTS.md and the .claude/skills/ folder in the project with the latest from the Fusebase CLI project template. Use this to refresh agent rules and skill documentation without re-running fusebase init. Requires fusebase.json in the project root.

Create or update .env (MCP token)

fusebase env create

Creates or overwrites .env with DASHBOARDS_MCP_TOKEN and DASHBOARDS_MCP_URL. Use after fusebase init or when the MCP token has expired. Requires fusebase.json (with orgId) and fusebase auth to be set.

Configure optional MCP integrations

fusebase integrations

This runs an interactive step to enable/disable optional MCP servers from the CLI integrations catalog and any custom HTTP MCP servers listed under fusebase.json → mcpIntegrations.custom. required: true servers are always enabled when you run this command.

Add a custom MCP by URL (checks reachability with HTTP GET unless --skip-check):

fusebase integrations add <name> --url <url> [--type http] [--token <token>]
fusebase integrations disable <name>   # keep fusebase.json; remove from IDE configs
fusebase integrations enable <name>
fusebase integrations remove <name>    # or: delete

During fusebase init, only required MCP servers (per the catalog, respecting flags) are written to IDE configs; run fusebase integrations afterward to add optional servers.

Create Feature Secrets

fusebase secret create --feature <featureId> --secret <KEY:description> [--secret ...]

Creates secrets (with empty values) for an app feature and prints the URL where you can set the actual values.

Required Options:

• --feature <featureId> - Feature ID to create secrets for
• --secret <KEY:description> - Secret to create. Format: KEY or KEY:description. Repeatable — pass multiple --secret flags to create several secrets at once.

Examples:

# Create a single secret
fusebase secret create --feature abc123 --secret "API_KEY:Third-party API key"

# Create multiple secrets at once
fusebase secret create --feature abc123 \
  --secret "API_KEY:Third-party API key" \
  --secret "DB_PASSWORD:Database connection password" \
  --secret "WEBHOOK_SECRET"

After creating the secrets, the CLI prints https://{org-domain}/dashboard/{orgId}/apps/features/{featureId}/secrets — open that URL to fill in the actual secret values.

Deploy Features

fusebase deploy

Deploys all features to Fusebase:

1. Installs dependencies and runs lint for each feature (if the feature has a lint script in package.json)
2. Runs each feature's build command
3. Uploads the built files from outputDir
4. Activates the new version on Fusebase

The project template includes ESLint (npm run lint) and root npm run typecheck (TypeScript across features — catches errors ESLint does not). Run both before saying "Done" so deploy succeeds; see AGENTS.md "Final Gate". Claude Code runs lint and typecheck on Stop via .claude/settings.json hooks.

Remote Logs (Deployed Backends)

Fetch logs from deployed feature backends. Only applicable to features with a backend/ folder. Use this for production issues, NOT for local development (for local dev, see the dev-debug-logs skill).

Build Logs

fusebase remote-logs build <featureId>

Fetch the build image logs from the most recent deployment. Shows the container image build output.

Runtime Logs

fusebase remote-logs runtime <featureId> [--tail <number>] [--type <console|system>]

Fetch runtime logs from the deployed container.

Options:

• --tail <number> - Number of log lines to fetch (default: 100, max: 300)
• --type <console|system> - Log type: console for app output, system for container system logs (default: console)

Examples:

# Get build logs for a feature
fusebase remote-logs build abc123

# Get last 100 runtime console logs
fusebase remote-logs runtime abc123 --tail 100

# Get system logs (container lifecycle events)
fusebase remote-logs runtime abc123 --type system

Creating a New Feature

1. Create the feature directory under features/:

   features/
     my-new-feature/
       package.json
       vite.config.ts
       src/
         App.tsx
         main.tsx
   

2. Implement the feature code — write all source files, components, and logic.

3. Register and start dev — execute these automatically after the code is written; do NOT list them as "next steps" for the user:

   a. Run fusebase feature create — include --permissions now if the feature needs dashboard access (do not save it for a separate feature update step later):

   # Without dashboard access
   fusebase feature create --name="My New Feature" --subdomain=my-new-feature --path=features/my-new-feature --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist
   
   # With dashboard view permissions (preferred: set at creation)
   fusebase feature create --name="My New Feature" --subdomain=my-new-feature --path=features/my-new-feature --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist --permissions="dashboardView.dash123:view456.read,write"
   
   # With a backend
   fusebase feature create --name="My New Feature" --subdomain=my-new-feature --path=features/my-new-feature --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist --backend-dev-command="npm run dev" --backend-build-command="npm run build" --backend-start-command="npm run start"
   

   This will create the feature on Fusebase and add it to fusebase.json

   b. Run fusebase dev start to test locally

Updating an Existing Feature

After changing feature code, run fusebase feature update <featureId> if any of these need to be updated:

• --permissions — dashboard view access added, removed, or modified
• --access — access principals (visitor / org roles) changed
• --sync-gate-permissions — always include for features using @fusebase/fusebase-gate-sdk at runtime

# Update permissions and sync Gate permissions
fusebase feature update <featureId> --permissions="dashboardView.dash1:view1.read,write" --sync-gate-permissions

Typical Workflow

1. fusebase auth - Authenticate (one-time setup)
2. fusebase init - Initialize project
3. Implement the feature code under features/<name>/
4. (after code is written) fusebase feature create --name="Feature Name" --subdomain=feature-name --path=features/feature-name --dev-command="npm run dev" --build-command="npm run build" --output-dir=dist [--permissions="..."] - Create and configure feature; include --permissions at this step if the feature needs dashboard access. Execute automatically — do NOT list as next steps for the user. 4a. (after registering) fusebase dev start - Start dev and test locally. Execute automatically.
5. (if feature settings changed) fusebase feature update <featureId> [--permissions="..."] [--sync-gate-permissions] - Sync updated settings before deploying
6. fusebase deploy - Deploy to production
7. fusebase remote-logs build|runtime <featureId> - Check logs if deployed app has issues (see remote-logs skill for more)

Troubleshooting

"Not authenticated" error

Run fusebase auth to set your API credentials.

Feature not showing in dev server

Ensure the feature is:

• Registered via fusebase feature create (so it exists in Fusebase and fusebase.json)
• Added to fusebase.json with correct id
• Has a running dev server (the dev.command process is up)

Build fails during deploy

Check that:

• npm run lint passes in the feature directory (deploy runs lint before build)
• npm run typecheck passes from project root (or fix TypeScript errors from the feature’s tsc step — ESLint alone may not report them)
• build.command is correct
• build.outputDir exists after build
• All dependencies are installed in the feature directory (npm install --include=dev)
