This package aims to help the loading, compiling and managing data of Golang's Templates.
go get "github.com/gale93/stemp"
In this folder we have 2 different type of files
- .tmpl
- .html
stemp will compiles the templates and make them viable in the following way: Pseudo code:
For Each [Html file]
Join it all [.tmpl] files...
Handling data is very easy because it's already done !
Stemp struct has these two functions :
AddData(name string, data interface{})
RemoveData(name string)So you can manage the data you want to cast to template in 2 different ways:
-
You can add static data you ALWAYS want to pass to all templates just calling AddData() function one time at the start of the program
-
You can pass specific data to the template and Remove() it after it is used. Somewhat like this:
func fakehandler(w http.ResponseWriter, r *http.Request) {
st.AddData("lottery_numbers", []int{3, 2, 9, 2, 3, 12})
st.Render(&w, "home.html")
st.RemoveData("lottery_numbers")
}You will have a base.tmpl file that looks like this:
base.tmpl
{{define "base"}}
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Stemp</title>
<meta name="description" content="Stemp">
<meta name="author" content="Matteo Galeotti">
{{template "includes" .}}
</head>
<body>
<nav></nav>
<div id="content">
{{template "content" .}}
</div>
</body>
</html>
{{end}}
{{define "includes" }}{{end}}
{{define "content" }}{{end}}And a index.html who is the specific content while the user land on main page:
index.html
{{define "content"}}
<h1> Welcome </h1>
{{end}}So your Golang file will looks like this !
package main
import (
"fmt"
"net/http"
"os"
"stemplate/stemp"
)
var st *stemp.Stemplate
func handler(w http.ResponseWriter, r *http.Request) {
st.AddData("anything_you_want", &TheStructYouNeed)
st.Render(&w, "index.html")
}
func main() {
var err error
// Just give to Stemplate Plugin the folder of your templates and it will do the rest
st, err = stemp.NewStemplate("./views/")
// Use this when you are in development and dont want to restart server after modify html files
st.LiveReload = true
if err != nil {
fmt.Println("error initialitating Stemplate")
os.Exit(1)
}
http.HandleFunc("/index", handler)
// Let's get this party started
http.ListenAndServe(":9393", nil)
