- Using JSON Web Tokens with Node.js
- API authentication is one of the biggest challenges when building an API and one of the biggest security vulnerabilities of the API. The correct authentication mechanism helps avoid security threats and ensures that only authorized users can access the required data. Authentication used to be simple when dealing with server-side applications. Simple session verification on the server is sufficient to ensure user permissions to the operation. However, the advent of APIs has brought significant changes to these authentication challenges. However, for APIs, you cannot implement a session. You cannot guarantee that your API is always called using a web browser, so you cannot rely on cookies to protect your API. One of the key features of an API is its statelessness, which means sending to the API

- Build a GraphQL Gateway: Combine, Stitch or Merge any Datasource
- Core points GraphQL gateways combine the advantages of traditional API gateways and GraphQL, allowing software engineers to obtain data from multiple data sources while maintaining front-end efficiency. The backend, i.e., frontend (BFF) architecture reduces the number of requests on the frontend, simplifying the process by allowing a single request to the API gateway, which then fetches data from each backend service and combines it. GraphQL provides BFF with many advantages, including efficient data acquisition, a single endpoint for all requests, and flexible queries that allow the front-end to select only the required data for each request. The three recommended frameworks for establishing GraphQL gateways include Hasura, StepZen, and Graphweaver.
