Question 1

How does LARS compare to httprouter?

Accepted Answer

LARS is based on a custom version of httprouter, adding features like customizable context and unified middleware, but it inherits limitations such as no static/dynamic route coexistence. It's better for flexibility but requires more setup.

Question 2

Can I use standard Go http handlers with LARS?

Accepted Answer

Yes, LARS fully supports native http.Handler and http.HandlerFunc, with examples provided, though you need to handle context quirks manually when using Go 1.7's integrated context.

Question 3

How to add custom middleware in LARS?

Accepted Answer

Middleware uses the same definition as handlers; register them with l.Use() or per route. For custom patterns, use RegisterCustomHandler to avoid type casting, as shown in the custom handler example.

Question 4

What are the performance benchmarks for LARS?

Accepted Answer

Benchmarks in the README show zero allocations and fast routing times, e.g., 51.6 ns/op for param routes, making it competitive with other high-performance routers like httprouter.

Question 5

Is LARS good for building a full web framework?

Accepted Answer

Yes, LARS is designed as a modular base for custom frameworks, with its interface-driven design allowing incremental addition of features, but you'll need to build or integrate components like templating and database layers.

Question 6

How does LARS handle URL parameters and form data?

Accepted Answer

LARS automatically adds URL parameters to the Form object when parsing forms, similar to query parameters, simplifying data access in handlers without extra work.
