What is api framework?

 framework is skeleton with guidelines to follow. Some premises follow internal approved framework to apply the project..

Api is one which is connect or expose interface to consumer. 

In simple term, Framework is rules to follow traffic, api is how you travel or deliver efficiently  :)

A framework or software framework is a platform for developing software applications. API framework is a foundation on which software developers can build applications for a specific platform.

Example: A framework can include predefined classes and functions that can be used to process input, manage hardware devices and interact with system software.

The framework is similar to an Application Programming Interface, technically framework includes API. The framework serves as the foundation for programming while API provides access to the elements supported by the framework. The framework also includes code libraries, compilers,s and other programs used in the software development process.

API framework is defined by a configuration file that consists of the list of all APIs that are required to be activated and activated for a particular program run.

The framework is the skeleton holding the library or libraries. The API is the programming interface allowing you to interact with another application or operating system. It pulls from sources of code within the framework to work with other sources of code or applications of the code.

API - Application Programming Interface : which enables two or more systems to communicate using a common language even though those applications are built on different platform. 

Frameworks are published structure / pre-developed environment set ready for development with built-in classes and/or functions. 

You can develop an API application using a tech stack like NodeJS / Python / Ruby .etc.,

Once you have choosen the stack then you can go for the selection of framework say in NodeJS you have Express, Sails, and so on.. 

Those frameworks will have the default libraries, file structure and boiler plate ready to start with. And you may have to follow the
