Canonical 3F app

Yes, this is required. We can use the food-delivery app that has been referenced in the doc as the canonical app. We also need a corresponding analytics app for evaluation purposes.

Deployment

3 steps (no puns)

1. Step 1 ( realtime graphql) - Deploy Hasura on Heroku
2. Step 2 (state models and async serverless) - Create data models and deploy lambdas (using serverless framework)
3. Step 3 (event system) - Create event triggers

Evaluation

1. Fast iteration

Place an order.
See updates.
Change the subscription to show more/different details
Place an order
See new updates instantly.

2. Resilience

Frontend crashes - close the frontend during status updates. open it again and show correct status.
Backend crashes - Backend stops responding (undeploy lambda). Redeploy lambda and things are back to normal.

3. Scalability

Using graphQurl, place orders for 1000 users per second. See analytics app for realtime updates.

Thoughts?

Hey there, thanks for the response!

Personally it sounds good to me and would love to deploy such as sample app.

We have built such apps before. Here is an example: https://github.com/shahidhk/hasura-serverless

Just need to make it canonical and reference-ready :)

Hi everyone

Took a while but a full step-by-step canonical app is ready: https://github.com/hasura/3factor-example

Please go through it and post your doubts :)
