string-replace-webpack4-plugin

string replace plugin for webpack

Usage example

var StringReplacePlugin = require("string-replace-webpack4-plugin");
module.exports = {
   module: {
      loaders: [
         // configure replacements for file patterns
         { 
            test: /index.html$/,
            loader: StringReplacePlugin.replace({
                replacements: [
                    {
                        pattern: /<!-- @secret (\w*?) -->/ig,
                        replacement: function (match, p1, offset, string) {
                            return secrets.web[p1];
                        }
                    }
                ]})
            }
      ]
   },
   plugins: [
      // an instance of the plugin must be present
      new StringReplacePlugin()
   ]
}

This allows for arbitrary strings to be replaced as part of the module build process. The original intent is to replace API keys in modules prior to deployment.
