When building a FastAPI project with PostgreSQL, you need a reliable way to manage your database schema over time. As your application evolves, simple table creation is not enough. You need a way to safely apply, track, and roll back changes.
Alembic provides a structured, version-controlled approach to database migrations. In this guide, weโll walk through how to set up Alembic with FastAPI, SQLModel, and PostgreSQL, including common issues youโll run into when working with Docker.
Choosing an API framework depends on both your application’s needs and your development team’s strengths. In this article, we explore Express vs FastAPI by building the same API in both frameworks and examining differences in tooling, ecosystem support, and runtime behavior.
This blog walks through building a clean, modular service layer in Flutter to keep mobile apps scalable, maintainable, and resilient to change. Using real examples with third-party APIs, it demonstrates how to abstract logic, structure code for API calls, and easily swap data sources without major rewrites. Youโll also learn strategies like creating request/response classes and centralizing error handling to reduce redundancy and improve code quality.
When an application struggles to keep up with user demand, slow response times can frustrate users and impact business performance. Without proper optimization, heavy traffic can lead to slow load times, system crashes, and lost opportunities. At Keyhole Software, we specialize in helping businesses optimize API performance for high-traffic applications to ensure their systems remain fast, reliable, and scalable. In …
Test coverage is a metric that measures how much of your codebase is exercised by tests, providing insight into the effectiveness of your testing efforts. In this blog, weโll focus on API projects, exploring the types of tests suited for code coverage, realistic goals (and tools to help achieve them), and the minimum coverage needed to reap the benefits of your tests.
Testing your codeโdown to individual linesโis a critical practice in modern software development. It helps ensure applications remain reliable, stable, and maintainable, all while balancing practical constraints.
