Dependency Map

Format: List all external dependencies of your project and assess each dependency's risk.

Steps:

1. Open any one of your projects (or imagine one)

2. List all external dependencies:

   • Third-party services (Supabase, Vercel, Stripe, Claude API...)
   • npm packages (How many? Do you know what they all do?)
   • API integrations (Google Maps, SendGrid...)

3. For each dependency, fill in:

Dependency name: _____
Purpose: _____
If it disappeared tomorrow:
  - What happens to my app? (Completely unusable? Partial functionality affected?)
  - What's the alternative?
  - How long to switch to the alternative?
Risk level: High / Medium / Low

4. Draw a dependency graph — which dependencies depend on other dependencies?

Self-Assessment Criteria:

• Are there any "single points of failure"? (One service goes down, the entire app goes down)
• Are there any "hidden dependencies"? (Dependency chains you don't know about)
• Do your critical dependencies have alternatives?
