In this post, the author discusses building a CI/CD pipeline for Cloudflare Workers using Travis CI. The process involves creating a Worker script, optional unit tests, a serverless.yml file, a .gitignore file, and a .travis.yml configuration file. These files are stored in the same GitHub repository with a specific layout. The author then explains how to test the worker using mocha and cloudworker, create a serverless.yml file for deployment, and configure Travis CI for testing and deploying the worker. Finally, environmental variables are added to the build process, and the pipeline is tested.
