Large mobile video uploads are tough: backgrounding, network hiccups, and retries can break the flow. In this guest post, Petr Chalupa shows how the @strvcom team built a native upload pipeline using Expo Modules and AWS S3 multipart for reliable, background uploads in the Boom app. @ptrchalupa shows the code below ↓

I'm working with a SPA that has a dedicated backend composed of over a dozen microservices. Each service has its own repo, and its own DB, even though all services are built and maintained by one team. I do not recommend this. 🚩Can't do atomic commits 🚩Lots of friction jumping between repos and DB's 🚩Hard to configure CI, or to manage cross-repo breaking changes 🚩Repeated code between repos 🚩Hard to maintain data integrity between DBs 🚩Requires many HTTP calls to load a page (there's no BFF) 🚩No easy way to search/navigate between repos 🚩Complex cross-service transactions 🚩Doesn't honor Conway's law

Wonder what would happen if you went on a @GitHub repo and changed the URL from "github.com" to "github.dev"? 🙊
