refactor setting TTL in needs.js

[cg-cnu]

Thank you for your help :heart:

What is this project?

DAV (Decentralized Autonomous Vehicles) is a new foundation working to build an open-source infrastructure for autonomous vehicles (cars, drones, trucks, robots, and all the service providers around them) to communicate and transact with each other over blockchain.

The specific project you are looking at is Mission Control. It is the brain in charge of orchestrating missions between DAV users and autonomous vehicles.

How you can help

Mission Control comes with a built in simulation environment which generates and controls simulated vehicles, allowing developers to start developing without investing in costly hardware first.

One of the things the simulator does is keep track of requests for delivery missions.

Once created, those simulated requests remain indefinitely in memory.

Once we have many developers from around the world experimenting with the simulation environment, more and more requests will be created and kept in memory and never deleted.

What you can do

We need to add a TTL (Time To Live) expiration to the requests stored in Redis so that they are deleted automatically after some time.

In the file /server/store/needs.js the code used to set TTL is repeated twice redis.expire(`needs:${needId}`, config('needs_ttl')); The task for this issue is to refactor that code by moving it to a separate function with the name setNeedTTL(needId).
