Create and export a global function in your webpack configuration file (webpack.config.js) that can be accessed and utilized

Looking to dive into webpack for the first time. I am interested in exporting a global function, akin to how variables are exported using webpack.EnvironmentPlugin, in order to utilize it in typescript.

Experimented with the code snippet below just to understand its behavior:

module.exports = [{
  ...
  ...
  plugins: [
    new webpack.EnvironmentPlugin({
     env_func: function bindObj() {
        console.log("In plugin");
       }
    })
  ]
}]

However, upon trying to access it as

envFunc = process.env.env_func; envFunc.bindObj()
, I encountered the following error:

TypeError: Cannot read property 'bindObj' of undefined

Is there a method or specific plugin (similar to EnvironmentPlugin) available in webpack configuration for exporting a function that can be utilized from typescript?

Answer №1

webpack.EnvironmentPlugin provides a shortcut for creating functions using DefinePlugin. To ensure Typescript compiler recognizes it, you must declare the function by including a .d.ts file in the project:

xxx.d.ts
--------
declare function bindObj(): void;
declare function fun1(abc: string): number;
