So I am here to share the process and It's already on the templ documentation https://templ.guide/media/, but i have some issue on that I change here and there.
Install temp
go install github.com/a-h/templ/cmd/templ@latestadd
go get github.com/a-h/templto your projectnow make a dir/folder inside your go project e.g react-integration
cd react-integration and make two dir/folder static(where your templ and templ geneated go file should be) and another one react()
inside static create a page.tmpl
make sure you have data to pass if you need the data to render,
package static
import(
"github.com/username/myrepo/types"
)
*/
script renderIndex(bp types.BillingPlan) {
// Use the renderIndex function from the Reactbundle
bundle.renderIndex()
}
templ Index(bp types.BillingPlan) {
<div id="index"></div>
// in templ you this to call a templ component or script
@renderIndex(bp)
}
templ Page(bp types.BillingPlan) {
`<html>
<head>
<title>React integration</title>
<link rel="stylesheet" href="static/index.css"
</link>
</head>
<body>
<div id="react-header"></div>
<div id="react-content"></div>
<div>
</div>
// this index.js will be generate by es build
<script src="static/index.js"</script>
@Index(c, fs)
</body>
</html>`
}
After this run command** templ generate** so that it will generate the required go code( make sure inside static dir/folder)
- inside react do npm init -y make this files tsconfig.json
and install necessary package(ts, esbuild, react, react-dom)
or copy pasta this { "name": "react-integration", "version": "1.0.0", "description": "", "main": "index.ts", "author": "", "license": "ISC", "dependencies": { "react": "^18.2.0", "react-dom": "^18.2.0" }, "devDependencies": { "@types/react-dom": "^18.2.18", "esbuild": "0.20.1", "npm-run-all": "^4.1.5", "typescript": "^5.3.3" } }
we are using tsx for bundle so we use react for jsx
{
"compilerOptions": {
"jsx": "react",
"lib": ["ESNext", "DOM"],
"esModuleInterop": true,
}
}
- create your required files for me i will create components.tsx , index.tsx and app.tsx
components.tsx
`import React from "react";
export function Component(props:any){
return(
<div>
<h3 onClick={()=> console.log(data)>Click Me</h3>
</div>
)
}`
app.tsx
import React, { useEffect, useRef, useState } from 'react';
import { Component } from "./components"
const App = (props : any) =>{
// do whatever you want
return(
<Component billingPlan={props}/>
)
}
export default App
index.tsx
import ReactDOM from 'react-dom/client';
import React from 'react';
import App from './app';
export function renderIndex(content:any){
const root = ReactDOM.createRoot(document.getElementById('index') as HTMLElement);
root.render(
<App content={content} />
);
}
generate the index.js bundle using this command ./node_modules/.bin/esbuild --bundle index.tsx --outdir=../static --minify --global-name=bundle
- Now we have to serve I like to use echo framework
package main
import(
"github.com/labstack/echo/v4"
"github.com/username/types"
"net/http"
)
func main(){
e := echo.New()
// middleware for serving static file
e.Static("/static", "./integration-react/static")
// routes
e.Any("/shit",echo.HandlerFunc(func(c echo.Context) error {
// call the template component in the static
templComp := static.Page(types.BillingPlan{})
Render(c, http.StatusOK, templComp)
}))
s := http.Server{
Addr: ":8080",
Handler: e,
}
if err := s.ListenAndServe(); err != http.ErrServerClosed {
log.Fatal(err)
}
}
// this is the echo integration with templ code
func Render(ctx echo.Context, statusCode int, tc templ.Component) error {
ctx.Response().Writer.WriteHeader(statusCode)
ctx.Response().Header().Set(echo.HeaderContentType,
echo.MIMETextHTML)
return tc.Render(ctx.Request().Context(),
ctx.Response().Writer)
}
