The blog post outlines the process of building and deploying a composable React application to Netlify using Bit, a platform where everything functions as a component. It explains how to create a new React app with Bit, integrate the Netlify deployer component, and utilize Bit's commands for easy deployment. The post emphasizes the component-driven approach, allowing independent building, testing, and deployment of components, which can be assembled like Lego blocks to create more complex applications. This method enables efficient updates and deployments by tagging only the affected components, saving time and resources. Additionally, the post introduces Ripple CI, a component-driven continuous integration tool that promises faster builds by isolating changes and running tests only on impacted components. The blog also mentions the flexibility of the deployment pipeline, which can be expanded with different deployers like Cloudflare, showcasing Bit's adaptability in component-based software engineering.
