Using webpack CLI

webpack CLI

One way to verify that webpack is installed on your system is by using the webpack CLI (Command Line Interface). This command-line tool allows you to interact with webpack and perform various operations, including checking the version. To check the installed version of webpack, open your terminal and run the following command:

webpack –version

This command will display the version number of webpack installed on your system, confirming that webpack is installed and available for use.

The webpack CLI is a powerful tool that provides a wide range of features and options for managing your webpack projects. It allows you to bundle your JavaScript modules, optimize your code, and configure various loaders and plugins. By using the webpack CLI, you can easily verify the installation of webpack and ensure that it is ready to be used in your projects.

Using npm or yarn list command

Another method to confirm webpack installation is by using the npm or yarn list command. Running the command “npm list webpack” or “yarn list webpack” will display the installed version of webpack along with the name of your project and the version range. This command provides a detailed view of the dependencies and their versions within your project.

Here is an example output of the npm list command:

    ├── project-name@1.0.0
    ├── webpack@4.46.0
    └── ├── webpack-cli@4.9.0
        └── webpack-dev-server@4.5.0
  

In the example above, the project name is “project-name”, and webpack is installed at version 4.46.0. It also shows that webpack-cli and webpack-dev-server are dependencies of webpack.

Similarly, when using the yarn list command, you will get a similar output with the installed version of webpack and its dependencies:

    ├── project-name@1.0.0
    ├── webpack@4.46.0
    └── ├── webpack-cli@4.9.0
        └── webpack-dev-server@4.5.0
  

By utilizing the npm or yarn list command, you can easily verify the webpack installation and gain insights into the installed version along with its dependencies.

Programmatically Determining Webpack Version

When working with Webpack, it’s important to be able to programmatically determine the installed version. This can be useful for various reasons, such as ensuring compatibility with other dependencies or performing version-specific tasks. Luckily, there are different methods you can use to achieve this.

If you’re using Webpack 2 or later, you can make use of the build environment key “–env.version”. By specifying “–env.version” followed by “$(webpack –version)” or “$(webpack -v)”, you can retrieve the installed Webpack version. This allows you to access the version number directly within your build environment.

Note: Ensure that you have the Webpack CLI installed globally or locally in your project for the above commands to work.

In Webpack 4 and later, you can access the version property directly. This means that you can create a global constant holding the Webpack version using a configuration file and the DefinePlugin. For example, you can define “WEBPACK_VERSION” to equal the Webpack version. This constant can then be accessed in your code whenever needed.

By being able to programmatically determine the Webpack version, you have more control over how your project interacts with this powerful module bundler. This flexibility can help you ensure that your project is running on the correct version and take advantage of the latest features and improvements.

4.41.2 4.44.2 Update available

In the example above, the installed version of webpack is 4.41.2, while the latest version available is 4.44.2. The “Status” column indicates that an update is available. It is recommended to keep your webpack installation up to date to benefit from bug fixes, performance improvements, and new features.

Checking locally installed webpack module

locally installed webpack module

If you have installed webpack locally to a project, you can easily check the installed version by inspecting the package.json file. To do this, navigate to the node_modules/webpack/package.json file within your project directory.

Once you locate the package.json file, open it and look for the “version” field. The value of this field will indicate the installed version of webpack for your project. This simple step allows you to verify the webpack installation and ensure you are working with the correct version.

Checking the locally installed webpack module can be particularly useful when you have multiple projects with different webpack configurations. By referencing the package.json file, you can quickly identify the webpack version specific to each project, helping you manage and troubleshoot your webpack setups effectively.

Steps Description
Step 1 Navigate to the node_modules/webpack/package.json file within your project directory.
