Other times APIs are asynchronous, which means that their responses can come at a later time so we can continue with our work while waiting for the response. Sometimes API are synchronous, meaning that we have to wait for their response to our requests before we can continue our operation. We normally talk about APIs in the context of internet network applications, but API is a more generic term that describe interfaces between any kind of applications.įor example, an application like Axios has an API that it uses to communicate with other applications. It's the interface that is used by an application, typically a front-end application, to talk to the back-end application.ĪPI are methods and functions that wrap some operations. They are any kind of service (data, computation, actions, activities, events) that need to occur in support of other applications needs.ĪPI is an acronym that means: Application Programming Interface. It's used by other applications.īack-end applications often include databases but they don't have to. The back-end also has an interface, but this interface is not used (or consumed) by the end user. That interface is made of components like buttons, dropdown menus, pages, fonts, etc. When we create a front-end application, we create an interface for the user to interact with.
In web development, back-end is a service that sends data to the front-end. We can think of back-end as applications that communicate with one another.
What back-end means in the context of web application developmentĪ large part of application development for the web has to do with what is called back-end.
