Introduction
Deploying JavaScript applications is an essential step in the software development lifecycle. It involves packaging the application and making it available for users to access. In this blog post, we will explore various methods of deploying JavaScript applications, including hosting, deployment tools, and continuous integration/continuous deployment (CI/CD) pipelines.
Hosting
One common way to deploy a JavaScript application is by hosting it on a server. This can be done using platforms like Amazon Web Services (AWS), Google Cloud Platform (GCP), or Netlify. By uploading your application files to a server, you can make your application accessible to users through a URL.
Deployment Tools
Deployment tools automate the process of deploying applications, making it quicker and more efficient. One popular deployment tool for JavaScript applications is Github Actions. By creating a workflow in Github Actions, you can automate the process of building and deploying your application whenever changes are made to the codebase.
Here is an example Github Actions workflow for deploying a React application:

CI/CD Pipelines
CI/CD pipelines automate the process of testing, building, and deploying applications. This ensures that changes to the codebase are quickly integrated and deployed without manual intervention. Jenkins and Gitlab CI/CD are popular tools for setting up CI/CD pipelines for JavaScript applications.
