Echo Framework for Golang
Echo framework is a high-performance, extensible, minimalist web farmwork for Go. When we create the RESTful APIs, We can use the echo framework.
If you using the echo framework you should know these things,
1. How to use handler
Handlers are the meat of web application development where all business logic is stored. Handlers are primarily where the application converts the input into an output. The handler type in echo is a function that takes in an echo "context" and returns an error.
2. How to define Routes
We need to define routes to our handlers within the echo server instance there are helper methods to add the target path to the router to handlers.
3. How to define middleware
Think of middleware as a wrapper for the handlers we create. Middleware functions are a great way to enrich requests with common functionality, that can be reusable across the application handler code. Echo provides lots of middleware but we can use the default middleware "logger".
4. Run microservices
After all the previous steps, we can compile the code and run the application with a port.
Features of echo framework
- Optimized Router::
Highly optimized HTTP router with zero dynamic memory allocation which smartly prioritizes routes.
2. Scalability::
Build robust and scalable RESTful API easily organized into groups.
3. Middlewares::
Many built-in middlewares to use or define your own middleware can be set at root, group, or route level.
4. Data Binding::
API to send a variety of HTTP responses, including JSON, XML and etc...
5. Extensibility::
Customized central HTTP error handling. Easily extensible API.
