How do I add middleware to fasthttprouter?

Middleware can be chained before the router by using fasthttp.RequestHandler functions. The README provides examples like auth and multi-hosts middleware, and links to writing custom middleware, making it flexible but manual.

Is fasthttprouter faster than httprouter?

Yes, according to benchmarks in the README, fasthttprouter is shown to be even faster than httprouter when used with fasthttp, due to optimizations specific to the fasthttp framework for high performance.

Can I use fasthttprouter with net/http?

No, fasthttprouter is specifically designed for fasthttp and does not work with net/http. The README explains that fasthttp uses a different handler interface (RequestHandler), so it's incompatible with standard library tools.

How to handle static files with fasthttprouter?

Static files can be served using the NotFound handler or by setting up a route with a catch-all parameter. The README suggests using paths like /static/*filepath for cleaner routing and to avoid sidestepping core rules.

Does fasthttprouter support nested routes or groups?

The router supports hierarchical RESTful APIs through its tree structure, but for route grouping, you need to manage patterns manually as it doesn't have built-in group syntax like some frameworks (e.g., Gin).

fasthttprouter or gin: which is better for high performance?

Fasthttprouter is optimized for fasthttp and likely faster in that context, while Gin is built on net/http. Choose fasthttprouter if you're committed to fasthttp for extreme speed; otherwise, Gin offers more features and net/http compatibility.

What are the performance benchmarks for fasthttprouter?

The README includes benchmark graphs showing it handles 5000 concurrent clients with low latency, and it's cited as processing 17 million requests per day in production, validating its stability and speed.

What is fasthttprouter?

FastHttpRouter is a high-performance HTTP request router designed for the fasthttp server framework in Go. It efficiently routes incoming HTTP requests to handlers using a radix tree structure, solving the need for fast and scalable routing in high-concurrency applications. The router is optimized for minimal memory usage and maximum speed, making it ideal for performance-critical web services.

Target Audience

Go developers building high-performance web servers or APIs with the fasthttp framework who need efficient and reliable request routing.

Value Proposition

Developers choose FastHttpRouter for its exceptional speed, zero garbage allocation during matching, and explicit routing that eliminates ambiguity. It is a stable, production-tested router that scales well under heavy load.

Overview

A high performance fasthttp request router that scales well

Use Cases

Best For

Building high-throughput RESTful APIs with fasthttp
Developing low-latency microservices in Go
Handling large numbers of concurrent HTTP requests efficiently
Creating hierarchical URL structures with path parameters
Serving static files with clean routing rules
Implementing middleware chains before request handling

Not Ideal For

Projects using the standard Go net/http package, as it's exclusively tied to fasthttp
Teams needing a full-featured web framework with built-in templating, authentication, or ORM
Applications requiring regex-based routing or complex pattern matching beyond named/catch-all parameters
Developers who prioritize a large ecosystem with extensive third-party middleware and community plugins

Pros & Cons

Pros

Blazing Fast Performance

Benchmarks in the README show it outperforms other routers, handling high concurrency with minimal latency, making it ideal for high-throughput applications.

Explicit Route Matching

Each request matches exactly one route, eliminating ambiguity and improving SEO, as highlighted in the features section.

Efficient Path Handling

Automatically corrects trailing slashes, wrong cases, and superfluous elements like ../, reducing developer overhead for URL normalization.

Zero Garbage Allocation

The matching process generates no heap allocations for paths without parameters, optimizing memory usage in performance-critical scenarios.

Cons

Fasthttp Dependency

Locked into the fasthttp ecosystem, which may not be compatible with libraries or tools built for the standard net/http package, limiting portability.

Minimal Built-in Features

As a router only, it lacks integrated middleware or advanced web framework features, requiring manual chaining for common functionalities like authentication.

Limited Third-party Support

The README notes no high-level frameworks are built on it yet, indicating a smaller ecosystem compared to more established routers like httprouter.
