To build a serverless API, you need to set up a Go environment and install GoogleCloudSDK, then write an HTTP function to handle the request, and finally deploy to CloudFunctions through gcloudCLI. 1. Install Go1.18 and GoogleCloudSDK and configure the project; 2. Create Go modules and write HTTP processing functions, support GET and POST methods, process JSON input and return response; 3. Simplify the code and only retain the Handler function, remove local server logic; 4. Use the gcloud command to deploy the function, specify the runtime, entry point and trigger method; 5. Test the GET and POST interfaces of the API, verify the return

Use Go's embed package combined with the Gin framework to embed static files into binary files to achieve single file deployment; 2. Embed templates/ and assets/ directories into variables templateFS and assetFS through the //go:embed directive; 3. Use template.ParseFS to parse the embedded template file and call r.SetHTMLTemplate to set Gin's HTML template; 4. Use r.StaticFS("/static", http.FS(assetFS)) to serve as static file; 5. Access http://localh

Go code performance analysis can be implemented through the built-in pprof tool. First, import the debug endpoint to enable the \_"net/http/pprof"; 1. For HTTP services, start the pprof interface of localhost:6060 in the program; 2. Use gotoolpprof http://localhost:6060/debug/pprof/profile?seconds=30 to collect 30 seconds CPU performance data; 3. Analyze the memory allocation through gotoolpprof http://localhost:6060/debug/pprof/heap; 4. Enable run

logrus is suitable for projects that require rich functions and ease of use, with medium performance and low learning curve; 2.zap is suitable for high-performance production services, with extremely high performance but medium learning curve; 3.zerolog is suitable for applications that pursue extreme performance and simplicity, with extremely fast speed and zero memory allocation; 4.slog is suitable for new Go1.21 projects, providing standardized structured logs without external dependencies, with good performance and low learning curve; 5.apex/log is suitable for cloud-native applications and scenarios that require multi-backend support, with high flexibility and medium learning curve; overall it is recommended to choose based on Go version, performance requirements and whether you rely on third-party libraries. New projects are preferred, and zap or zerolog are selected for high-performance scenarios.
