The Spin SDK for JavaScript and TypeScript has improved its developer experience by aligning with popular patterns and tools.The HTTP router capabilities were moved from the Spin SDK for JS, allowing users to choose their preferred router like Hono.Hono Router is a lightweight system for handling HTTP requests efficiently with an intuitive API and middleware support.Updating Spin templates is recommended before starting a project using tools like spin new -t http-ts routing-with-hono.Instructions are provided on how to create a Spin app with TypeScript and Hono Router, including defining routes and middleware.Testing the default implementation involves compiling code to WebAssembly and running the application locally.Building a Restful HTTP API with Hono includes implementing handlers for various routes and error handling.Permission to use external resources like key-value store is granted by updating the component configuration in spin.toml.Running and testing the Spin app involves compiling the code and using curl to interact with different endpoints.Leveraging Hono's routing capabilities with Spin helps in creating efficient, secure, and scalable APIs.
