A Hackerhearth chalenge (SlicePay NodeJS Hiring Challenge) for make API in node and express js, for a given stocks data from 2005 to 2016

Stock Data Repo

[Problem Statement]

Develop a pseudo backend Application for Stock Data Repo. A data dump is provided which contains the stocks related historical data from 2005 - 2016. Your web app should be an archive of historical stocks trading data. Users should be able to fetch history of desired stock prices using APIs you expose.

[Ideal Behaviour]

• Write a backend which exports APIs with all the data provided in the dump below.
• Implement multiple APIs for validation of the request and retrieval of data.
• Your APIs should take multiple parameters to fetch data from backend, performs API key validation and other request validations.

[Minimum Requirement]

• Write a backend in tech stack mentioned below which exposes APIs which return response in JSON.
• Implement an API key validation.
• Implement APIs for:

companySearch: This service should take a company name and returns all the price points of that company over the entire duration.

timeFrame: This service should take two dates as input and should return 10 best performing and 10 least performing stocks in that time frame.

stocksInTime: This service should accept two parameters, “any number of stock tickers in a list” and “two dates”. This will return all the highs, lows and closes of these stocks in the desired time frame.

tickerSearch: This service should take the ticker symbol and should return all the price points in time of that ticker.

• Data APIs should be called internally after validation of incoming requests.
• Implement Postman collection for your APIs documentation.
• Zip all your source code, deployment instructions, screenshots and upload them.

[Extra Work]

Along with everything from the above level :

• Implement ORM Mongoose for data modeling in the backend.
• Perform thorough Unit Tests and submit a report.
• Write a script to test and deploy your backend.
• Use your imagination and add features which would make things easier for end users.
• Zip all your source code, executables(if any, viz. war file), deployment instruction, db dump file, screenshots and upload them.

[Ideal Stack]

Backend : NodeJS - Express, Golang, ORM Mongoose Db : MongoDB

[Installation Process]

• clone the github repo Link
• start mongodb by running this command "sudo service mongod start"
• import the csv file in mongodb, name the database as "node_stock" and collection name as "stocks", and import it.
• now open the terminal and goto the root folder of the project and run "npm run dev" make sure you have installed nodejs locally. It will start a local server in 5001 port.
• Open Postman application, and import the collection from postman folder which is in json format
• Now check for output for each API

• for company search api

• for time frame api

• for stock in time api

• for ticker api
