Notes
- fairly consistent experience
- http server
- golang.org to download and install
- runs on linux,mac and windows (others as well)
- after installing need to use two more tools - terminal and text/code editor
- when in the terminal you can type in 'ls' to see the directories
- when you type 'pwd' you can see what directory you are currently in
- use mkdir 'some name' to create a new directory
- type 'pwd' again to confirm that you are in your new directory
- then type 'go version' to see if it is installed
- go code will be done in text
- create a new file in text editor and name it 'main.go'
- go file will always have the following 3 parts - a package (and its name) , import statements , your code
- need to write a function called main - this is where everything will start
- to declare a function you need to write 'func' and the name ex :
func main' ( ) { }- code will go in the { }
- put spaces between the { }
- go back to the terminal - need to come up with an import path
- go supports custom import paths
- in the terminal to create the import path you will need to type 'go mod init <website>/<project name>' e.g.
go mod init first.last.com/mygoproject - it should say ' creating new go module'
- command
go run .( this will run the command in the current working directory) - go to 'godoc.org/net/http' we will scroll down to look at an example for a web server
- put this into your code within the { } :
{ func main ( ) { http.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) { fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path)) }) log.Fatal(http.ListenAndServe(":8080", nil)) } - now we need to import ---> under package main put 'import "net/http" ', 'import "log"', 'import "fmt" ', ' import "html"'
