Frequently Asked Questions about Fiber
What is Fiber?
Fiber is an Express-inspired web framework written in Go, designed for high performance, minimal memory footprint, and fast HTTP handling. It leverages Go’s concurrency model for scalable web applications and APIs.
What are the primary use cases for Fiber?
High-performance REST APIs. Microservices and cloud-native applications. Real-time web applications. Backend services for mobile and web clients. IoT and messaging platforms
What are the strengths of Fiber?
Blazing fast due to Go runtime. Simple and intuitive API. Lightweight and minimal dependencies. Built-in support for common middleware. Scales efficiently in concurrent environments
What are the limitations of Fiber?
Smaller ecosystem compared to frameworks like ASP.NET Core or Laravel. Fewer tutorials and enterprise resources. Not ideal for extremely complex server-side rendering projects. Limited built-in ORM (requires third-party libraries). Less opinionated structure may lead to inconsistent project organization
