7. Building with Lightning Web Components Open Source!
Our dashboard will
● Use LWC OSS for UI
● Subscribe to a streaming topic
● Pull Salesforce Data
● Show interaction with other NPM Modules
● Pretty Graphs!
Did you know LWC is Open Source?

8. What we’ve already built.
● A basic Node (express) app - (create-lwc-app)
● Wired up JSForce
● Subscribed to a Streaming Topic
So we need to:
● Write some lightning web components to display our chart
● Wire up Socket.IO - to forward streaming api data to the client
● Give the app some basic structure (header, etc.)
Through the magic of television, we’ve already built these things

We’re working with this project:

10. This way to the code
In case Kevin forgets, this is where we (finally) get away
from the slides and to the coding bits.

11. Today we
Created a node based dashboard app
Used Lightning Web Components - OSS to build a reusable and modular UI
Incorporated third party Javascript libraries like Socket-io and Charts.js into our web components
Setup Salesforce to stream update notifications to our app, and pull data from Salesforce on
demand with JSForce
mAd3 n0 Tyops.

12. Key Takeaways
Lightning Web Components are Open Source and can be easily used off-platform!
LWC OSS components play nicely with other Javascript libraries!
It’s easy to surface data from your Salesforce org in external applications!
Remember this!
