SFDX Lightning Web Component Drone Delivery Route Optimisation

Drone Delivery screenshot

Description

You want to deliver your company's orders using drones? Great idea! However drones can't fly for very long so efficient flight paths are a must. Select the right customer contacts on the right then click the button to let Heroku calculate the optimal flight path for your delivery drone!

Purpose

An example Lightning Web Component that uses Heroku to process Salesforce data and return a rich insight to the end user.

Usage

  1. After you spin up a Scratch org, activate geolocation data service for the org. In the setup menu under Data -> Data Integration Rules -> Geocodes for Contact Mailing Address -> Activate
  2. Assign permission set to your user: sfdx force:user:permset:assign -n DroneDeliveryUser
  3. Add some Contacts manually, or add more entries to the Contact.json file here and use sfdx force:data:tree:import -f Contact.json
  4. Check the custom field Droneport__c checkbox of a single Contact so it becomes the "warehouse" from where the drone flies out.
  5. There's a hardcoded city filter for 'Sydney' at the moment, so you don't get too many results back from your contact list. If you're getting no contacts in the list change this.

Heroku

Heroku is the fastest way to get from idea to url. We deployed a simple Python Flask server to respond to our API calls. The API receives a json payload with a list of coordinates and uses the Google OR Tools open source library to find the most efficient route. More information www.heroku.com

See this repo for the API server: https://github.com/feliperyan/optimal-flight-path-api
