Railway has introduced a new feature called Railway Functions, designed to streamline and significantly accelerate the deployment process for developers. This innovation allows code to be deployed within 45 seconds, eliminating the need for package managers, GitHub repositories, infrastructure as code (IaC), or container builds, thus simplifying the deployment workflow to just the code itself. Powered by the Bun runtime, Railway Functions offer native code execution in containers, leveraging infra-less compute similar to Railway Services. The process involves parsing source code, analyzing dependencies, installing them with the fast-performing Bun installer, and executing TypeScript/JavaScript without prior transpiling. This rapid deployment capability, which can be achieved in as little as one second, enhances productivity by allowing developers to experiment, iterate, and ship projects more efficiently. Currently supporting TypeScript, Railway plans to extend support to additional languages in the future, providing developers with tools like REST API, JSX landing pages, and cron utilities to facilitate diverse use cases.
