Web applications commonly gather user input through form submissions. Node doesn’t handle the workload (like validation or file uploads) for you—Node just provides you with the body data. Although this may seem inconvenient, it leaves opinions to third-party frameworks in order to provide a simple and efficient low-level API.
Suppose you want to create a to-do list web service with Node, involving thhe typical create, read, update and delete(CRUD) actions. These actions can be implemented in many ways, but in this article we'll focus on creating a RESTful web service
GraphQL is a middleware that allows the user to have one endpoint to handle most requests on your express server. There are many benefits of using this.
A frequent requirement for e-commerce sites, and sites dealing with sensitive data, is to keep traffic to and from the server private. Standard HTTP sessions involve the client and server exchanging information using unencrypted text. This makes HTTP traffic fairly trivial to eavesdrop on.
Many web applications share similar, if not identical, needs, and serving static files (CSS, JavaScript, images) is certainly one of these. Although writing a robust and efficient static file server is nontrivial, and robust implementations already exist within Node’s community, implementing your own static file server in this section will illustrate Node’s low-level filesystem API.
