Create React App Officially Deprecated Amid React 19 Compatibility Issues
Create React App is officially deprecated due to React 19 issues and lack of maintenance—developers should switch to Vite or other modern alternatives.

Hey, people want to buy products.
Building this microservice to scale better.
Cut a piece from the monolith and serve chilled.
Have to be generated. So I have generated a client with GoDoc. Client documentation
The package structure is simple for a reason. Currently, this is a straightforward service, so almost everything is in a single package, where business logic, data storage, and API code is located in separate files. Later if service will become more complex, there will be a need for better granularity and code isolation. But for now, I feel like this is the right balance.
In the future packages structure will be derived from domains, and not from the functionality that code provides. An example would be:
Not:

Carts rely on other microservices.
Some microservices rely on Cart.
To run all tests: go test github.com/cooldryplace/cart/...
.
To skip integration tests: go test --short github.com/cooldryplace/cart/...
.
The current integration test does not cover cases when storage or other dependency fails.
Currently, only API and client metrics are implemented. This already allows measuring availability and latency. In the future, I can add more specific metrics that will not be used in SLO implementations but will be in dashboards. To pinpoint the root cause of a problem during incidents. So we alert based on SLIs, look at the dashboard, and know where and why it happens.
Adding spans here and there will help to identify bottlenecks. I use Opencensus with Stackdriver exporter for this.
The current DB schema does not allow us to shard data. FKs and autoincrement are in the way. The suggested next step is to handle constraints in the application code. Start using UUIDs.
