What to Learn: Reading and writing files, working with JSON, CSV, and XML. Why it’s Useful: Many applications require file handling for configuration, logging, or data storage.
What to Learn: SQL and NoSQL databases, using database/sql, GORM ORM, and migrations.
Why it’s Useful: Go is widely used for backend services, making database management crucial.
What to Learn: Using Go’s net/http package, building REST APIs with Gin/Echo, and handling middleware. Why it’s Useful: Web services are a primary use case for Go, enabling scalable and fast applications.
What to Learn: JWT authentication, OAuth2, session-based authentication, RBAC (Role-Based Access Control). Why it’s Useful: Securing applications is essential for protecting user data and system integrity.
What to Learn: Writing unit tests, using the testing package, mocking dependencies, and Test-Driven Development (TDD).
Why it’s Useful: Ensuring application correctness and reducing regression issues.
What to Learn: Working with Docker, Kubernetes, Terraform, and deploying Go applications. Why it’s Useful: Go is widely used in DevOps, making it crucial for infrastructure automation.
What to Learn: Reflection, generics, unsafe package, and memory management. Why it’s Useful: Understanding advanced topics allows writing more efficient and sophisticated applications.
What to Learn: Using pprof, benchmarking, race conditions, and debugging tools like Delve.
Why it’s Useful: Optimizing Go applications ensures better performance and reliability.
What to Learn: Implementing WebSockets, building real-time applications, and integrating with frameworks like NATS. Why it’s Useful: Real-time functionality is essential for messaging and collaborative applications.
What to Learn: Exploring useful packages like bufio, json, io, fmt, and popular third-party libraries.
Why it’s Useful: The Go ecosystem is rich, and leveraging existing libraries speeds up development.
What to Learn: Building microservices, using gRPC, REST, and service discovery tools like Consul. Why it’s Useful: Microservices architecture is a common approach in modern backend development.
What to Learn: Using log, zap, logrus, integrating with Prometheus, and distributed tracing.
Why it’s Useful: Logging and monitoring are key to maintaining application health and debugging issues.
What to Learn: Preventing SQL injection, securing APIs, encrypting data, and validating input. Why it’s Useful: Writing secure code prevents vulnerabilities and ensures compliance with security best practices.
What to Learn: Using Go for ML with Gorgonia, TensorFlow Go bindings, and data analysis libraries. Why it’s Useful: While Go is not the primary ML language, its efficiency makes it a good fit for production workloads.
