Introduction

The GoFrame framework offers powerful, rich, and unified error handling capabilities implemented through the gerror component. This component is also the unified error handling component of the framework. All components of the framework, if there is an error returned, are accompanied by stack information to facilitate developers in quickly identifying issues.

📄️ Error Handling - Methods

Common methods for error handling in the GoFrame framework, including error creation, error wrapping, and functions related to error codes, providing multiple ways to create and wrap custom error messages to help developers effectively manage errors and debug code when using the GoFrame framework.

📄️ Error Handling - Stack

Error handling stack features in the GoFrame framework, implemented through the gerror module to trace error stacks and enhance the readability and maintainability of error information. The article explains in detail how to use the Wrap method to layer error information, the HasStack method to check error stacks, the Stack method to get stack information, and methods to access error information at different levels.

📄️ Error Handling - Comparison

Comparison methods in error handling within the GoFrame framework, including the usage of Equal and Is methods. The Equal method is used to determine if two error objects are the same, while the Is method is used to determine if a given error is in a specified error chain. Interface definitions and usage examples are provided to help developers better understand and apply these methods.

📄️ Error Handling - Other Features

In GoFrame framework, error handling other features include how to use NewOption to customize error object creation, print complete stack information through fmt formatting, and powerful support for log output. Additionally, from version v2.6.0, the error component offers different printing modes for stack information, meeting development needs in different scenarios.

📄️ Error Handling - Best Practices

Effectively handle errors in the GoFrame framework, including printing stack information of error objects and correctly using the Wrap method to encapsulate error objects, avoiding duplication of error messages. Through specific code examples, demonstrate how to optimize error handling and improve the stability of GoFrame framework applications.

📄️ Error Handling - Performance

Covers benchmark performance testing for error handling using the GoFrame framework, providing performance comparison results of commonly used methods. These performance tests allow developers to better understand and optimize error handling efficiency in Go programming, thereby enhancing the overall performance of applications. Data is sourced from the open-source GoFrame project on GitHub, listing detailed performance results of different error handling methods under various configurations for developers' reference.
