In this article, we will help you in hiring Golang developers. We will help you get developers proficient in writing codes and using RESTful APIs to improve server performance. 

 

We will also understand the criteria for selecting developers who excel in system integration and maintainability. Let’s know more! 

What are RESTful APIs in Golang?

Before you begin to hire Golang developers, gain a thorough understanding of RESTful APIs.

RESTful  APIs in Golang bring a solid way to build web services that interact with clients and other servers. Golang has a simple syntax and powerful standard library that helps developers to build APIs that efficiently handle requests. These APIs also respond well to a stateless communication model. 

RESTful APIs follow the REST (Representational State Transfer) architectural style. It further uses standard HTTP methods like GET, POST, PUT, and DELETE.

Key Skills and Qualifications for Golang Developers

Before you hire Golang developers, first go with the assessment of the following technical skills and soft skills:

Technical Skills

• Experience with Frameworks Like Gin: Familiarity with popular Go frameworks such as Gin or Echo is also very important. These frameworks assist in setting up scalable and streamlined web servers and APIs.
• Understanding of RESTful Architecture: Developers should know how to curate and implement RESTful services. It includes knowing how to produce endpoints that handle different HTTP methods. It also includes status codes and middleware. These are vital for building scalable web applications.
• Deep Knowledge of Golang: Proficiency in Golang development is the most important requirement. Developers should have a stronghold of syntax, data structures, and basic algorithms. Knowledge of Goroutines and channels for efficient concurrency is also essential.

Soft Skills

• Problem-solving Skills: The proficiency to troubleshoot and solve issues efficiently is a precious skill in development. Golang developers must be able to think logically and creatively. It helps them overcome challenges during coding and deployment.
• Teamwork: Collaborating effectively with other developers, managers, and stakeholders is also a mandatory skill. 

Additional Qualifications

• Database Management: Knowledge of database management is also vital for golang development. It includes understanding SQL and NoSQL databases, schema design, and incorporating databases with Go applications.
• Familiarity with Cloud Technologies: So many companies are moving to cloud platforms which makes experience with AWS, Google Cloud, or Azure important. This includes administering services and resources in the cloud.

Setting Up a RESTful API Using Golang With Dedicated Developers

Hiring Golang developers is crucial for setting up a RESTful API in Golang as it involves several complex steps:

Step 1: Initialize Your Server

Begin by hiring a Golang developer to set up a basic server using Golang’s standard HTTP library. It involves configuring the server to listen on a specified port and defining routes that the server will respond to. This setup is the backbone of your API. It assists in handling incoming HTTP requests and routing them to the appropriate handlers.

Step 2: Handle Different Types of Requests

Advertisement

Your API needs to respond to various HTTP methods. These methods majorly include: GET, POST, PUT, and DELETE. Each type of request corresponds to different operations:

• GET requests fetch data from your server.
• POST requests put in new data.
• PUT requests update existing data.
• DELETE requests withdraw data.

Step 3: Manage Data

Data management involves interacting with a database to retrieve, store, and update information relying on the user’s requests. Hire Golang developers skilled in data handling to ensure that your API provides a clear and timely response.

Step 4: Utilize Concurrency

Concurrency is one of Golang’s standout features. It helps your server to manage multiple requests simultaneously. This is achieved through goroutines, which are lightweight threads supervised by the Go runtime. By using goroutines, Golang developers can perform database operations, process data, and handle user requests.

Always hire Golang developers with experience in this implementation process. Their expertise will help you use Golang’s efficiency and speed effectively.

Top Golang Frameworks for Building RESTful APIs for Developers

• Gin Framework

Pros:

• High Performance: Gin is known for its high performance. It is also one of the fastest web frameworks for Go. It has a neat and minimalistic design with efficient middleware handling.
• Easy to Use: Gin bestows a simple API that makes routing and middleware integration simple. 

Cons:

• Less Flexibility: Due to its minimalistic approach, Gin might be less flexible in complex applications. 

Best Use Scenarios:

• Most promising for applications that need high speed and efficiency, such as microservices or real-time data processing systems.

• Echo Framework

Pros:

• Rich Feature Set: Echo provides a comprehensive feature set that includes automatic TLS. It is a router that supports static and dynamic routing along with a middleware system.
• High Customizability: Echo allows more custom configurations than Gin which makes it suitable for complex applications.

Cons:

• Slightly Lower Performance Compared to Gin: While still fast, Echo may present a slightly lower performance than Gin because of its broader feature set.

Best Use Scenarios:

• Best for enterprise-level applications where a good range of features and customizability are required.

• Gorilla Mux

Pros:

• Powerful Routing Capabilities: Gorilla Mux is best for its powerful and versatile routing capabilities. It allows detailed route matching including regular expressions.
• Good Community and Support: It brings a large community and good support.

Cons:

• More Overhead: It can be heavier than other frameworks like Gin. It presents extensive functionality which may not be necessary for all projects.

Best Use Scenarios:

• Best for complicated applications where advanced routing capabilities are needed. It includes dynamic web applications or APIs that need detailed request handling.

Choosing the Right Framework

Selecting the right Golang framework for your RESTful API project depends on several factors which we will discuss now. However, the best way to deal with the framework and RESTful APIs is to hire Golang developers with sufficient expertise. 

• Performance Needs: Go with frameworks like Gin for high-performance requirements.
• Complexity of the Application: Employ Echo or Gorilla Mux if your project demands comprehensive customizability and complex routing.
• Development Speed: Select Gin for quicker development if simplicity and speed are priorities.
