Plan for NABB deployment

[duckbytes]

First steps

• Create a first release branch on GitHub
• Connect release branch to AWS Amplify on the AWS console
• Register subdomain on bloodbikes.org.uk (suggest: app.bloodbikes.org.uk)
• Generate SSL cert on AWS
• Set up SES and apply for unrestricted sending
• Connect bloodbikes.org.uk address up to SES for sending emails
• Set up a feedback email address to receive emails
• Create an API key on Google Cloud for location services (could use mine temporarily)
• Register a new tenant and admin for Freewheelers

Later steps

• Create mobile app installers with Cordova
• Apply for inclusion in Play and App store
• Improve multi-tenant support in preparation for adding more charities
• Properly integrate end to end testing

Known limitations

Selective sync

At the moment devices synchronise all data for a particular tenant on app first startup. This could mean long sync times for people who have not opened the app in a while.

I've done some experimenting with using syncExpressions with DataStore to reduce sync size, but relations between some records makes it difficult to find a solution.

Tracked on issue #73

Pick up and delivery addresses can only be cleared while the user is online

Issue tracked on aws-amplify/amplify-js#9520

Optimistic concurrency merge strategy

Auto-merge is broken currently and the merge strategy in use is optimistic concurrency, which is more limited and may cause unhandled conflicts. Amplify are working on a fix for auto-merge: aws-amplify/amplify-js#9979

End to end testing

End to end testing with Cypress is limited at the moment. More work needs to be put into extending and automating it.

Google Play Store

The app will need to be registered on Google Play.

• Create a developer account
• Create a service account
• Create API key of JSON type
• Publish a privacy policy (I quickly generated one on Termly that could be used)
• Build Android keystore for app signing
• Publish initial version of the app

Once these are set up, GitHub can automatically publish new versions to the Play Store.

I wrote these steps from memory after doing it myself, so could be some missing!
