When using the Golang framework, please note: use third-party libraries with caution to ensure stability and security. Avoid circular references and prevent memory leaks. Pay attention to Goroutine synchronization to avoid race conditions. When handling HTTP requests, be aware of resource leaks, XSS, and error handling. Use Go modules to manage dependencies, perform unit testing, and follow Golang best practices.

What are the precautions for using the golang framework?

Notes on using Golang framework

Golang framework is widely popular for its high performance, concurrency and ease of use, but you need to pay attention when using it Some matters.

Use guaranteed 3rd party libraries

Although third-party libraries provide a wide range of functions, they should be carefully selected and updated to ensure their stability and security. Additionally, if these libraries are deprecated or no longer maintained, the code may suffer maintainability and upgrade issues.

Practical case: Using outdated third-party libraries can cause the application to be incompatible with newer Golang versions, resulting in errors and crashes.

Avoid circular references

Circular references refer to two or more objects referencing each other, causing the garbage collector to be unable to release memory. This can cause memory leaks, which can negatively impact the performance and stability of your application.

Practical case: In Golang, if two structures contain fields that reference each other, it will cause a circular reference and trigger a memory leak.

Note Goroutine synchronization

Goroutine (Go coroutine) is a lightweight concurrency mechanism, but it needs to be properly synchronized to avoid race conditions when sharing data. Commonly used synchronization primitives include locks, channels, and wait groups.

Practical case: Without proper synchronization, multiple Goroutines may access shared data at the same time, resulting in inconsistent or unexpected behavior.

Things to note when handling HTTP requests

When handling HTTP requests, the following matters should be noted:

  • Resource leak:Not closed Database connections, file handles, or other resources can cause leaks and degraded performance.
  • Cross-site scripting attacks (XSS): Ensure user input is properly validated and sanitized to prevent XSS attacks.
  • Error handling: Provide friendly and useful error messages to help users identify and solve problems.

Practical case: Failure to close the database connection can cause resource leaks, thus affecting the overall performance of the application.

Other Notes

  • Using Go modules: Go modules help manage the versions and dependencies of third-party libraries, improve code reusability and Maintainability.
  • Conduct unit testing: Write comprehensive unit tests to ensure the correctness and stability of the code.
  • Follow Golang best practices: Follow the Golang code style guide and best practices to improve code readability and maintainability.
