When did the vendor come in in golang?
Golang official does not recommend the best package management solution. In the 1.5 version era, the official introduced the design of package management and added the vendor directory to support local package management dependencies.
The official wiki recommends a variety of package management tools that support this feature, such as: Godep, gv, gvt, glide, govendor, etc.
Even if using vendor, it must be in GOPATH. (Recommended learning: go)
The order in which to find dependent package paths
The vendor directory under the current package.
Search in the upper directory until you find the vendor directory under src.
Look for dependent packages under GOPATH.
Look for the package management tool govendor in the GOROOT directory
You need to add $GOPATH/bin/ to PATH.
Installationgo get -u github.com/kardianos/govendor
init 创建 vendor 文件夹和 vendor.json 文件
list 列出已经存在的依赖包
add 从 $GOPATH 中添加依赖包,会加到 vendor.json
update 从 $GOPATH 升级依赖包
remove 从 vendor 文件夹删除依赖
status 列出本地丢失的、过期的和修改的package
fetch 从远端库增加新的,或者更新 vendor 文件中的依赖包
sync Pull packages into vendor folder from remote repository with revisions
migrate Move packages from a legacy tool to the vendor folder with metadata.
get 类似 go get,但是会把依赖包拷贝到 vendor 目录
license List discovered licenses for the given status or import paths.
shell Run a "shell" to make multiple sub-commands more efficient for large projects.
go tool commands that are wrapped:
`+<status>` package selection may be used with them
fmt, build, install, clean, test, vet, generate, tool

Reading and writing files safely in Go is crucial. Guidelines include: Checking file permissions Closing files using defer Validating file paths Using context timeouts Following these guidelines ensures the security of your data and the robustness of your application.

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.

The Go framework stands out due to its high performance and concurrency advantages, but it also has some disadvantages, such as being relatively new, having a small developer ecosystem, and lacking some features. Additionally, rapid changes and learning curves can vary from framework to framework. The Gin framework is a popular choice for building RESTful APIs due to its efficient routing, built-in JSON support, and powerful error handling.

The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Best practices: Create custom errors using well-defined error types (errors package) Provide more details Log errors appropriately Propagate errors correctly and avoid hiding or suppressing Wrap errors as needed to add context

The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].
