How to Avoid Technical Debt When Using Starter Templates
How to Avoid Technical Debt When Using Starter Templates
Starter templates and boilerplates are powerful tools — but if used carelessly, they can introduce technical debt that slows you down later. Here are 10 strategies to keep your codebase clean.
1. Remove What You Don't Use
Most boilerplates include features you won't need. Unused code is the fastest way to accumulate debt.
Action: Before building any new features, identify and remove:
- Pages you won't use (pricing page if you're not SaaS)
- Auth methods you don't need (social login if you're email-only)
- Third-party integrations you won't use
- Example components and placeholder content
Warning: Remove carefully. Search for all references before deleting.
2. Understand the Architecture Before Changing It
Technical debt often starts when developers "fix" code they don't understand, breaking the original design patterns.
Action: Spend 1-2 hours reading the codebase before making changes. Understand:
- How data flows from frontend to backend
- How authentication is implemented
- How payments are processed
- What the folder structure conventions are
3. Follow the Template's Conventions
If the boilerplate uses Server Actions, don't introduce API routes. If it uses Prisma, don't add raw SQL queries. Mixing patterns creates confusion and bugs.
Action: Document the conventions you observe and enforce them on your team.
4. Don't Skip TypeScript Errors
It's tempting to add // @ts-ignore or as any to make errors go away quickly. Every ignored type error is a bug waiting to happen.
Action: Fix type errors properly. If a type doesn't fit, it usually means your data model needs adjustment.
5. Keep Dependencies Updated
Boilerplates ship with specific dependency versions. Over time, these become outdated, creating security vulnerabilities and compatibility issues.
Action: Run npm audit monthly and update dependencies quarterly. Major version upgrades may require code changes — don't postpone them.
6. Write Database Migrations, Not Schema Pushes
prisma db push is convenient for development but dangerous in production. It can silently drop data.
Action: Use prisma migrate dev to create proper migration files. Commit migrations to version control. Run prisma migrate deploy in production.
7. Don't Store Secrets in Code
Action: Keep all secrets (API keys, database URLs, tokens) in environment variables. Use .env.local for development, and your hosting platform's secrets management for production. Never commit .env files.
8. Add Error Handling Early
Boilerplates often have minimal error handling to keep code readable. Production apps need more.
Action: Add:
- Try-catch blocks around API calls
- User-friendly error messages (not raw error strings)
- Loading and error states for every data fetch
- Sentry or similar for production error tracking
9. Set Up Linting and Formatting
If the boilerplate includes ESLint and Prettier configs, use them. If not, add them.
Action: Configure pre-commit hooks (with Husky or similar) to run lint and format checks. This prevents style drift as the team grows.
10. Test Critical Paths
You don't need 100% test coverage for an MVP. But you should test the flows that, if broken, would kill your product:
- User signup and login
- Payment flow (checkout to webhook)
- Core product feature (the one thing users come for)
Action: Write integration tests for these three paths. Use Playwright or Cypress for end-to-end tests.
Technical Debt Warning Signs
| Sign | What It Means |
|---|---|
any types spreading through the codebase | Type safety is eroding |
| Multiple patterns for the same thing | Conventions aren't being followed |
| Build warnings increasing | Dependencies or code need attention |
| "It works but I don't know why" | Understanding gap that will bite later |
| Skipping code review to move faster | Quality controls breaking down |
Final Thoughts
Technical debt is interest on speed. Boilerplates give you a massive speed advantage — but that advantage erodes if you don't maintain code quality. Follow these 10 practices and you'll move fast without accumulating the debt that slows future development.
