There is no silent error. In practice, there are a couple fail safes:

- using both eslint and tsc: https://github.com/mickael-kerjean/filestash/blob/master/pub...

- the code is full of runtime assertions: https://github.com/mickael-kerjean/filestash/blob/1d1bad001b...

- unhandled error (like most assertion) will interrupt everything to show a scary looking screen: https://github.com/mickael-kerjean/filestash/blob/1d1bad001b...

- controlled error which are part of the regular error handling will stop the flow showing a screen like this: https://demo.filestash.app/?error=test
