Lightning Function Demos

Node.js + Platform Events

This demo uses a combination of Flow, Evergreen Functions, CDC, and Lightning Web Components.

Rough demo flow:

• Open account record
• Click Quick Action "New Delivery"
• Enter data in Flow, which will create a Platform Event
• Wait for "Current Deliveries" to update (CDC listens in LWC)

Salesforce org setup

1. Create scratch org.

sfdx force:org:create -s -f config/project-scratch-def.json -a routeplannerdemo

2. Push source to scratch org.

sfdx force:source:push

3. Assign permissionset

sfdx force:user:permset:assign -n RoutePlanner

4. Import sample data

sfdx force:data:tree:import -p data/Account-Service__c-plan.json

5. Open the org

sfdx force:org:open

6. In Setup go to Data -> Data Integration Rules, and activate Geocodes for Account Shipping Address.

Functions setup

As the DX is in flux this section only describes the minimum needed information.

• The function for this demo is located in functions/RoutePlanner.
• The permissionset to use is RoutePlanner - for function assignment and for the Platform Event assignment.

Route Planner Function

Once you complete the steps below to setup and run the Function you should see these records. DELIVERYROUTE__R.NAME shows the route the vehicle should take and NUMBER__C represents the waypoints on that route to each service location in the most optimal order.
