A NodeJs tool to serve a JSON data as REST end points.


$ npm install json-rest-serve


  • The JSON data should be an array of objects.
  • Each object (data item) should be identifiable with a primary key property.
  • The primary key should be either string or integer.
  • The data item can have nested objects within it.
  • The added resource should have atleast one data item in its data array.
  • The tool uses the first data item to understand the structure of it. It then uses this information to enforce the same structure during the POST and PUT operations.

How to use


  • Add one or more resources that you want to serve as REST endpoints.
  • After adding, call the serve method with your preferred port number.
  • name, key and data are required to add a resource.
