Yarn Install Production Only

Introduction

As a programmer, you may be familiar with the process of installing dependencies for your project. One popular package manager for JavaScript projects is Yarn, which allows you to manage your project's dependencies and install them easily.

In this tutorial, we will specifically discuss how to use Yarn to install production dependencies only. This is important because it ensures that your production environment only includes the dependencies necessary for your application to run properly.

Prerequisites

Before proceeding with this tutorial, you should have Yarn installed on your system. You can check if it's installed by running the following command:

yarn --version

If Yarn is not installed, you can install it by following the instructions on the official website: https://yarnpkg.com/en/docs/install

Installing Production Dependencies Only

To install only the dependencies needed for production, you can use the following command:

yarn install --production

This command will only install the dependencies listed in the dependencies section of your package.json file. It will skip over any packages listed in the devDependencies section, as those are only needed for development purposes.

It's important to note that this command will only install the production dependencies specified in your package.json file. If there are other dependencies that your project needs, but are not listed in the dependencies section, they will not be installed.

Conclusion

In this tutorial, we discussed how to use Yarn to install only production dependencies for your JavaScript project. By doing so, you can ensure that your production environment only includes the necessary dependencies for your application to run properly. Remember to always run yarn install --production before deploying your application to production, to ensure that only production dependencies are included.
