npm i --save-dev webpack-modern-build-plugin yarn add --dev webpack-modern-build-pluginThe plugin generates module/nomodule scripts and relies on html-webpack-plugin. This plugin expects to return two configurations in your webpack - legacy and modern. One of those values should be passed as mode option to the plugin in both configurations.
Example of webpack config:
webpack.config.js
const HtmlWebpackPlugin = require("html-webpack-plugin");
const WebpackModernBuildPlugin = require("webpack-modern-build-plugin");
module.exports = [
{
entry: "index.js",
output: {
path: __dirname + "/dist",
filename: "bundle.js",
},
plugins: [
new HtmlWebpackPlugin(),
new WebpackModernBuildPlugin({
mode: "modern",
}),
]
},
{
entry: "index.js",
output: {
path: __dirname + "/dist",
filename: "es5.bundle.js",
},
plugins: [
new HtmlWebpackPlugin(),
new WebpackModernBuildPlugin({
mode: "legacy",
}),
],
}
];This will generate a file dist/index.html containing the following
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Webpack App</title>
</head>
<body>
<script src="bundle.js" type="module" crossorigin="anonymous"></script>
<script>
(function () {
var d = document;
var c = d.createElement("script");
if (!("noModule" in c) && "onbeforeload" in c) {
var s = !1;
d.addEventListener(
"beforeload",
function (e) {
if (e.target === c) {
s = !0;
} else if (!e.target.hasAttribute("nomodule") || !s) {
return;
}
e.preventDefault();
},
!0
);
c.type = "module";
c.src = ".";
d.head.appendChild(c);
c.remove();
}
})();
</script>
<script src="es5.bundle.js" nomodule></script>
</body>
</html>The script in the middle between type="module" and nomodule is for Safari 10.1. This version supports modules, but does not support the nomodule attribute - it will load "script nomodule" anyway. This snippet solve this problem, but only for script tags that load external code.
