An API often exposes data that other developers can consume in their own apps, without worrying about databases or differences in programming languages.

This makes it a good fit for small projects as well as sophisticated single-page applications when used with other tooling and libraries.Īn API, or Application Programming Interface, is a software intermediary that allows two applications to talk to each other. It’s designed from the ground up to be incrementally adoptable, and it integrates well with other libraries or existing projects.
