Package Exports

json-minimizer-webpack-plugin

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (json-minimizer-webpack-plugin) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

json-minimizer-webpack-plugin

This plugin uses JSON.stringify() to minify your JSON.

Getting Started

To begin, you'll need to install json-minimizer-webpack-plugin:

$ npm install json-minimizer-webpack-plugin --save-dev

Then add the plugin to your webpack configuration. For example:

webpack.config.js

const JsonMinimizerPlugin = require("json-minimizer-webpack-plugin");
const CopyPlugin = require("copy-webpack-plugin");

module.exports = {
  module: {
    loaders: [
      {
        test: /\.json/i,
        type: "javascript/auto",
        use: [
          {
            loader: "file-loader",
            options: {
              name: "[name].[ext]",
            },
          },
        ],
      },
    ],
  },
  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(),
    ],
  },
};

This will enable JSON optimization only in production mode. If you want to run it also in development set the optimization.minimize option to true.

And run webpack via your preferred method.

Options

`test`

Type: String|RegExp|Array<String|RegExp> - default: /\.json(\?.*)?$/i

Test to match files against.

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
      new JsonMinimizerPlugin({
        test: /\.foo\.json/i,
      }),
    ],
  },
};

`include`

Type: String|RegExp|Array<String|RegExp> Default: undefined

Files to include.

webpack.config.js

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
      new JsonMinimizerPlugin({
        include: /\/includes/,
      }),
    ],
  },
};

`exclude`

      new JsonMinimizerPlugin({
        exclude: /\/excludes/,
      }),
    ],
  },
};

`minimizerOptions`

Type: Object Default: { replacer: null, space: null }

JSON.stringify() options.

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [
      new JsonMinimizerPlugin({

        },
      }),
    ],
  },
};
