Performance Comparison

Advanced Features

Cloud Caching

Share caches across your team or CI/CD environments:

flash-install --cloud-cache --cloud-provider=s3 --cloud-bucket=your-bucket-name

Workspace Support

Efficiently manage monorepo dependencies:

flash-install -w

Offline Development

Work without an internet connection:

# Create a snapshot while online
flash-install snapshot

# Later, restore dependencies while offline
flash-install restore --offline

Using Different Package Managers

# Use with Yarn
flash-install --package-manager yarn

# Use with PNPM
flash-install --package-manager pnpm

# Use with Bun
flash-install --package-manager bun

Additional Options

Here are some of the most useful options you can use with flash-install:

General Options

• --offline: Use offline mode (requires cache or snapshot)
• --no-cache: Disable cache usage
• --concurrency <number>: Number of concurrent installations
• --package-manager <manager>: Package manager to use (npm, yarn, pnpm, bun)
• --no-dev: Skip dev dependencies
• --verbose: Enable verbose logging
• --quiet: Suppress all output except errors

Workspace Options

• --workspace or -w: Enable workspace support for monorepos
• --workspace-filter <packages...>: Filter specific workspace packages

Cloud Options

• --cloud-cache: Enable cloud cache integration
• --cloud-provider <provider>: Cloud provider type (s3, azure, gcp)
• --cloud-bucket <name>: Cloud provider bucket name
• --cloud-region <region>: Cloud provider region

GitHub Actions Integration

Add Flash Install to your GitHub Actions workflow:

steps:
  - uses: actions/checkout@v3

  - name: Install dependencies with Flash Install
    uses: flash-install-cli/flash-install-action@v1
    with:
      # Optional parameters (shown with defaults)
      command: 'install'           # Command to run (install, restore, snapshot, clean)
      cache-enabled: 'true'        # Enable GitHub Actions caching
      package-manager: 'npm'       # Package manager to use (npm, yarn, pnpm, bun)
      concurrency: '4'             # Number of concurrent downloads

How It Works

1. Dependency Resolution: Parses lockfiles to determine exact dependencies
2. Workspace Detection: Identifies workspace packages in monorepos (when enabled)
3. Cache Check: Checks if dependencies are in the global cache
4. Snapshot Check: Checks if a valid .flashpack snapshot exists
5. Installation: If no cache or snapshot is available, installs dependencies using the package manager
6. Caching: Adds newly installed packages to the cache with optional compression
7. Snapshotting: Creates a .flashpack snapshot with fingerprinting for future use
