NodeJS server with APIs and operations on ElasticSearch and Redis DBs

Node.js and DBs

NodeJS server with two APIs and use them for data operations on ElasticSearch and Redis

API 1 '/index'

POST

This API takes in a sample message and indexes it into the ElasticSearch and Redis databases Although a single simple message can be used to demonstrate, I have considered a scenario where the user sends a document with keys 'name' and 'message' with his/her name and message to be stored, respectively. For Redis, I have chosen an ID counter for uniqueness of user's. This counter resets with every launch of the application. Alternate method: To avoid this reset, this count can be stored in the Redis DB itself to maintain continuation. I wanted to keep it simple !

GET

This route is used to get the data from the Redis DB. For this the user has to send a query with the parameter 'id' which corresponds to the user ID in the DB during creation.

API 2 '/search'

GET

This API is used to search for data from the ElasticSearch DB. To do so, the user can send the query with the 'str' parameter which can be a key:value pair or a simple string. The user can also send a GET request without any parameters to retrieve all the data in the ElasticSearch DB.
