I am trying to add automatic browser refresh to the dev environment for my preact ssr build.

webpack.config.js
const path = require("path");
module.exports = {
entry: "./src/index.js",
output: {
path: path.join(__dirname, "dist"),
filename: "app.js"
},
module: {
rules: [

test: /\.js$/,
use: {
loader: "babel-loader",
options: {

}
}
}
]
},
mode: 'development'
};
server.js
const express = require('express');
const path = require('path');
const render = require('preact-render-to-string');
const { h } = require('preact');
const { App } = require('./src/App');
const app = express();
const HTMLShell = (html) => `
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>preact ssr</title>
</head>
<body>
<div id="app">${html}</div>
<script src="./app.js"></script>
</body>
</html>
`;
app.use(express.static(path.join(__dirname, 'dist')));
app.get('*', (req, res) => {
const html = render(<App />);
res.send(HTMLShell(html));
});
app.listen(3001);
When I run yarn dev
, the webpack is correctly watching for any changes and rebuilding. I have to manually refresh the browser to see the effects, is there a way to automate this?
It doesn't look like you have
webpack-dev-server
as part of this project, which is responsible for handling the live reloading of your browser as changes occur. Start by adding that to your project:Then, replace the current
scripts
in your package.json with the following:Running
yarn dev
should give you live reload with recompiling after making that change.
