This is a REST API developed using MEAN stack. The dependencies are Express JS and Mongoose. The DB used here is MongoDB and the 'test' database is used for all crud operations.

1. NodeJS
2. Mongo DB
3. Postman (Chrome plugin) or any rest client to test the API

a. Clone this repo to a local machine directory and from the root directory, do an "npm install" command which installs all dependencies.
b. Start the local mongodb instance and check if mongodb is running on 27017.
c. Navigate to the project root directory and you must see a server.js file which is the entry point file.
d. Launch the REST API server with the command "node server.js". By default ,this is started on port 8080.
e. From here on ,the below rest apis can be tested.

i) http://localhost:8080/birds - GET call - should get all the visible birds.
ii) http://localhost:8080/birds - POST call - should create the bird record in the mongo db or return 400 [with some custom error message] if validation fails in the request body
iii) http://localhost:8080/birds/{id} - GET call - should return the bird by id or return 404 error code if record does not exist
iv) http://localhost:8080/birds/{id} - DELETE call - should delete the record by id or return 404 error code if record does not exist

I have used chrome plugin POSTMAN plugin as the client to test the rest apis.
