When dealing with async operations that depend on external systems (servers, backends, etc.), ensure proper synchronization to avoid race conditions. Don’t rely on client-side polling or workarounds when the root cause is improper async handling.
Key principles:
Example of proper async sequencing:
// Instead of client-side polling workarounds
async function start(openElectron) {
await initializeThings()
openElectron()
}
// Make functions async when they need to ensure completion
async function reset() {
await Cypress.backend("set:traffic:routing:reset")
}
This prevents race conditions where the UI renders before the backend is ready, or where operations proceed without confirming the previous step completed successfully.
