Creating a GraphQL endpoint in 60 minutes or less. Assaf Gannon, Javascript Architect, from Tikal. In this talk, we will address 2 of the most interesting topics in recent times - serverless and GraphQL. We will go over the requirements and key tools required to get started with both. We will demonstrate how simple it is to create a GraphQL endpoint and deploy it using Serverless services. Was originally presented at https://www.meetup.com/Fullstack-Developers-Silicon-Valley/events/250007589/

5. What is Serverless?
BaaS PaaS+

6. What is Serverless?
BL

BL
DB
Auth
PubSub
Queue
Cache
Logs
API
Storage

8. What is Serverless?
Small pieces of Business Logic deployed independently
Using Services for non-Business Logic stuff:
Persistance (DB / Cache / Static)
Messaging
Authentication / Authorization
Logging / Monitoring

9. What are the Pros
Seamless horizontal scaling
Fast and cheap ramp up
Pay as you go
High-end tech widely available

10. What’s the catch?
Vendor lock-in
Different development and Architecture paradigms
On-premise solutions can be difficult to set up and
maintain (see ‘Vendor Lock-in’)

11. Popular Vendors
AWS
GCP
Azure
Kubless

22. Ingredients
2 Lambda functions (GraphQL Query & Mutate)
1 DynamoDB store
Auth0 authentication

23. Getting started:
1. Install serverless CLI
(https://serverless.com/framework/docs/getting-started/)
2. Make sure AWS credentials are in place
3. Choose you language (Javascript, Java, Python, Go, C#
are supported)
4. Create a new Service via ‘serverless create`

24. Now what?!
1. Deploy your empty service
2. Add your functions and resources to serverless.yml
3. Start implementing your functions

25. 1.Deploy your empty service

26. 2. Add your functions and resources to serverless.yml

27. 3. Start implementing your functions
