Golang has become one of the most in-demand programming languages for building robust and scalable backend systems. With its growing popularity and wide adoption, the need for skilled Golang developers has also increased significantly.

This comprehensive guide will walk you through the key steps and requirements to start and build a successful career as a Golang developer in 2023.

What is Golang and Why Learn It?

Golang (or Go) is an open source programming language developed by Google in 2007. It combines the ease of development of dynamic languages like Python with the performance and efficiency of compiled languages like C/C++.

Here are some of the key advantages of Golang:

  • Simple and Easy to Learn: Golang has a simple and tidy syntax that is easy to learn even for beginners with no prior coding experience.
  • Fast Compile Times: Golang compiles extremely fast compared to other languages. This improves developer productivity.
  • Built-in Concurrency: Golang has built-in support for concurrency using goroutines and channels. This makes it easy to write concurrent programs.
  • Cross-Platform: Golang can compile code for multiple platforms like Windows, Mac, Linux etc. This makes deployment easy.
  • Mature Ecosystem: Golang has a thriving open source ecosystem with a vast array of libraries and frameworks for different use cases.
  • Scalable: Golang is designed with scalability in mind. Golang based systems and applications can easily scale from just a few requests to millions of requests per second.
  • Backed by Google: Being created by Google gives Golang credibility. Google itself uses Golang for many of its critical production systems.

For these reasons, Golang has seen massive adoption among software companies and developers. Mastering Golang opens up many exciting job opportunities.

Learn Golang – Steps and Resources

Here is a step-by-step process to start learning Golang:

Step 1: Learn Go Language Basics

Start with going through the official Golang tour. This will teach you the basics of the language including syntax, data types, functions, pointers, structs etc.

Next, go through the “Effective Go” guides. These contain best practices for writing idiomatic Golang code.

Step 2: Build Some Simple Programs

Apply what you learned to implement some simple programs that utilize various Golang concepts like functions, structs, interfaces, goroutines etc.

Examples: File I/O, CLI tools, Web Server, Simple database program.

Step 3: Understand Concurrency in Golang

Concurrency is a key strength of Golang. Read extensively about Goroutines and Channels which enable easy concurrent programs.

Learn how to use wait groups for synchronization. Understand mutex locking for shared data access between goroutines.

Step 4: Learn Standard Library and Tools

The Golang standard library and tools contain very useful packages like:

  • net/http – HTTP client and server implementation
  • encoding/json – JSON serialization
  • testing – Unit testing framework
  • fmt – Formatting utilities
  • flag – CLI argument parsing
  • pprof – Performance profiling

Get familiar with using these standard packages in your projects.

Step 5: Build Web Services

Use the net/http package to build web servers and APIs. Start with simple JSON based CRUD APIs and then move to more complex REST APIs with authentication, middleware, routing etc.

Popular Go web frameworks like Gin, Revel can help accelerate development.

Step 6: Connect to Database

Learn to integrate database access into your Golang applications. Use the database/sql package for connecting to SQL databases like MySQL, Postgres etc.

For NoSQL databases like MongoDB, use ODMS like mgo. Write code to perform CRUD operations on databases.
