Microservice Backend in Typescript for Polkachain Explorer

Abstract

Creating a micro service backend is quite simple but the challenge comes when the code has to be tested and optimized,structured, cleaned and maintained and thus here we follow the Eslint Typescript backend structure. The backend structure has followed the MVC architecture and followed the eslint rules to provide strictness in code. Focus on more functional components than class components. Talking about the database, we have used the no sql type database CQL providing fast read query. Polkadot functions are implemented to interact with the blockchain and other libraries are used for testing and printing-saving logs.
