Creating a Webpack bundle that includes third-party JavaScript files consists of utilizing the appropriate configuration settings

After researching Webpack and checking similar posts on stackoverflow, I'm still struggling to add additional files to my bundle. Currently, I've successfully included my js modules in the bundle.js file, but now I want to incorporate other files as well:

<script src="~/Scripts/jquery-3.2.1.js"></script>
<script src="~/Scripts/dx.all.js"></script>
<script src="~/Scripts/go-1.7.11.js"></script>

How can I achieve this using an import clause? Should I include them in the entry .ts file or in the webpack.config.js file?

I attempted the following approach, but it didn't work as expected:

In the entry .ts file:

import './../Scripts/jquery-3.2.1.js';
import './../Scripts/dx.all.debug.js';
import './../Scripts/go-1.7.11.js';

import { Caller } from './Caller';

window.onload = () => {
    let caller: Caller = new Caller();
    caller.execute();
};

UPDATE:

1) Changes made to webpack.config.js:

module.exports = {
    entry: './Main.js',
    output: {
        filename: 'bundle.js'
    }
};

2) All additional .js files are located in the same folder as the Main.js file.

Answer №1

Prior to diving into any specific solution, let's first understand the fundamental concept of webpack:

  1. Webpack necessitates an entry point and a designated output location
  2. Upon execution, webpack generates a dependency graph starting from the specified entry
  3. All resources within the dependency graph are then processed by webpack
  4. Loaders can be utilized for customized processing of various resources such as JavaScript, CSS, TypeScript, etc
  5. The processed resources are ultimately stored in the specified output location

Addressing your query, it is customary to incorporate require("./resource"); or import directly in the source files where functionality is required, rather than in the webpack.config.js. As previously mentioned, webpack solely requires an entry which should declare its dependencies.

To resolve the issue at hand:

  1. Ensure proper configuration of the entry within the webpack.config.js
  2. Add additional JavaScript files using require("") or import within the appropriate source files. The current imports in your entry seem correct given that the path is accurate.

Please update the original post to include:

  • webpack.config.js
  • folder structure

If the problem persists, consider the following:

UPDATE: You appear to be attempting to use TypeScript code without incorporating relevant transpilation configurations in webpack. Webpack has the ability to transpile TypeScript into JavaScript, with comprehensive documentation available here.

As aforementioned, loaders handle resource-specific tasks. It is advisable to experiment with the babel-loader.

Additionally, ensure that all dependencies are clearly outlined within your source JS/TS files. The entry file (Main.js) should declare all necessary modules as dependencies (using import or require). How Main.js establishes dependence on entry.ts remains unclear based on your provided information.
