Google Chrome continues to lead as the most popular web browser globally, with its extensive range of extensions enhancing user productivity and experience. The process of developing and deploying Chrome Extensions is evolving, with automation playing a crucial role in streamlining updates and bug fixes. A practical example of this is the creation of a simple Tab Counter extension, which counts open tabs and serves as a learning tool for building continuous integration/continuous deployment (CI/CD) pipelines using CircleCI. Automating the deployment process through CircleCI, Google Chrome Web Store API, and shell commands significantly reduces manual effort, minimizes human error, and ensures updates are consistently delivered. The guide outlines the prerequisites, including setting up Google OAuth credentials and configuring a CircleCI pipeline to automate the deployment of a Chrome Extension. Advanced practices such as handling development vs. production builds, using Git tags to control deployments, and employing workspaces for multi-step workflows are also discussed to enhance the deployment process.
