Redis pool less is a wrapper in redis client to handle connections in serverless and stateless environment. Servers running in stateless env such as google cloud functions, aws, serverless and kind of servers, can have this wrapper to open/close connection in a controlled env.

yarn add node-redis-pooless or npm install node-redis-pooless

• We don't use connection pool because it is stateful and serverless is stateless.
• As serverless is a quick way execution you must code the callback as simple as possible to return/execute the redis client call.
• A best scenario is to have unlimited connections once stateless doesn't work with connection pool. So you might want to work with no connection problems, if you can predict the number of connections, you might not have any problems with this wrapper.

const value = await redis(async (client)=>{
  return client.get(key)
})

await redis(async (client)=>{
  return client.set(key,value)
})
