In webpack, you can set the 'src' directory as the resource root by configuring the resolve object in your webpack.config.js file. You can specify the root directory by setting the 'root' property to the path of your 'src' directory. This tells webpack to resolve modules and imports relative to this root directory. For example, you can set it like this:
1 2 3 4 5 |
module.exports = { resolve: { root: path.join(__dirname, 'src') } }; |
This way, when you import modules or assets in your code, webpack will look for them relative to the specified 'src' directory.

What is webpack dev server?
Webpack dev server is a development server that is built into Webpack. It provides live reloading functionality, which means that any changes made to the code will automatically trigger a reload of the application in the browser. This allows developers to quickly see the effects of their changes without having to manually refresh the page.Webpack dev server also supports hot module replacement, which allows for the replacement of modules without a full page reload. This can greatly speed up the development process by preserving the state of the application while updating only the changed modules.
How to define the entry point in webpack?
The entry point in webpack is the starting point of your application where webpack will begin building its dependency graph. To define the entry point in webpack, you need to specify the path to your main JavaScript file in the webpack configuration file (usually named webpack.config.js).
Here is an example of how you can define the entry point in a webpack configuration file:
1 2 3 4 5 6 7 |
module.exports = { entry: './src/index.js', // path to your main JavaScript file output: { filename: 'bundle.js', // output bundle file name path: path.resolve(__dirname, 'dist') // output directory } }; |
In the example above, the entry point is set to ./src/index.js, which means webpack will start building the dependency graph from this file. You can replace ./src/index.js with the path to your main JavaScript file. Make sure to update the output configuration with the desired output file name and directory as well.
By defining the entry point in your webpack configuration, webpack will start bundling your application from that file and resolve all its dependencies as specified in the code.
How to use the module federation plugin in webpack?
To use the Module Federation plugin in webpack, you need to follow these steps:
- Install the module federation plugin: First, you need to install the Module Federation plugin by running the following command:
1
|
npm install webpack@5 webpack-cli@4 @webpack/container @module-federation/plugin
|
- Configure the Module Federation plugin in your webpack configuration file: Add the following code to your webpack configuration file (typically webpack.config.js):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
const { ModuleFederationPlugin } = require("webpack").container; const path = require('path'); module.exports = { entry: './src/index.js', output: { path: path.resolve(__dirname, 'dist'), filename: 'main.js', }, plugins: [ new ModuleFederationPlugin({ name: 'app', remotes: { remoteApp: 'remoteApp@http://localhost:3001/remoteEntry.js', }, shared: ['react', 'react-dom'], }), ], }; |
- Start your webpack build: Run the webpack build command to build your application with the Module Federation plugin configuration.
- Import remote modules in your application: Once you have configured the Module Federation plugin in your webpack configuration, you can import remote modules from other applications by using the import() function. For example:
1
|
const RemoteApp = React.lazy(() => import('remoteApp/App'));
|
- Start the remote application: Make sure the remote application is running and serving the remote entry file at the specified URL in the Module Federation plugin configuration.
That's it! You have successfully used the Module Federation plugin in webpack to enable module sharing across different applications.
