Strategy for how and when to clear cache will also vary accordingly. npm install --save axios express redis response-time Redis Installed? ‘/vehicle’ (POST route): Using this route we save the data of a new vehicle in the database. Like in the route ‘/’ we are getting all the data stored in our database. Here is how we are going to do that. ‘/:vehicleType/:sno’ (GET route): Using this route we will send the ‘vehicletype’ and ‘serialno’ as parameters and get the details of that vehicle as response. It’s typically used for caching frequently queried data, for eg: something like user-session information. Redis cache is pretty expensive so very large or less frequently queried data should not be cached. Now we can use this Redis connection in our jobs — for example, let’s define a job to process the current URL and save the result in MongoDB. We also used mongoose to create the schema. Other than this it can also be used as a message broker or as temporary storage. If you just want to quickly dive into the code, here’s the project repo. Caching is a strategy aimed at tackling the main storage problem, which means: the bigger the storage is, the slower will be, and vice versa. How to build a React website in AWS within 15 minutes. 3.
