Inside the endpoint, we make Redis cache the data against a specific key and return the response if the appropriate cached data is available without hitting our external API. Firstly, we have initialized the Redis client on the port of choice. Let us explain what is happening in the above piece of code.

Const searchtext = Ĭlient.get(searchtext, async (err, data) => `)
