JsonMinimizerWebpackPlugin
This plugin uses JSON.stringify() to minify your JSON files during the build process.
Getting Started
To begin, you'll need to install json-minimizer-webpack-plugin:
npm install json-minimizer-webpack-plugin --save-dev
or
yarn add -D json-minimizer-webpack-plugin
or
pnpm add -D json-minimizer-webpack-plugin
Then add the plugin to your webpack configuration. For example:
webpack.config.js
const CopyPlugin = require("copy-webpack-plugin");
const JsonMinimizerPlugin = require("json-minimizer-webpack-plugin");
module.exports = {
module: {
rules: [
{
test: /\.json$/i,
type: "asset/resource",
},
],
},
plugins: [
new CopyPlugin({
patterns: [
{
context: path.resolve(__dirname, "dist"),
from: "./src/*.json",
},
],
}),
],
optimization: {
minimize: true,
minimizer: [
// For webpack@5 you can use the `...` syntax to extend existing minimizers (i.e. `terser-webpack-plugin`), uncomment the next line
// `...`
new JsonMinimizerPlugin(),
],
},
};Finally, run webpack using the method you normally use (e.g., via CLI or an npm script).
