Using JSON web tokens in Deno

Deno, a modern and secure runtime for JavaScript and TypeScript, offers built-in TypeScript support and uses third-party packages with browser-compatible URLs for module management. In this context, JSON Web Tokens (JWT) are employed for authentication, as they allow for the creation and validation of tokens to manage user access. By integrating JWT into a Deno application using the djwt package, developers can generate and validate tokens, setting up routes with the Oak library to handle requests. The process involves creating a JWT with a secret key, payload, and header, and implementing routes to generate and validate tokens using methods from the djwt library. This approach enhances application security by providing a reliable method for user authentication, illustrating the practical use of JWTs in Deno applications.
