When developing code that calls on APIs (Application Programming Interface) it can be a pain having to call the API multiple times just whilst coding the initial call or during testing.
NPM (A package manager for Node) has a package that solves this called json-server.
It can be installed via:
npm i -g json-serverThe i NPM to install and the -g sets it as global install.
json-server can then be run using:
json-server --watch filename.json -p 8000The –watch switch is optional but I use it to point to a specific JSON (JavaScript Object Notation) file which I want to serve.
The -p switch is also optional and can be used to specify which port json-server should run on. I use it to stop it clashing with ports already in use by other running applications.
json-server then serves the JSON file as a response, and if the file has been populated in a similar way to the real API would respond then it allows for lots of testing / calls without having to call the real API.
