Safari Private Browsing

[danielschuetter]

When running Safari (both Desktop and iOS) in private mode the 'req' in Line 506 is null which results in a Type Error. (TypeError: Attempted to assign to readonly property.)

Could you please handle this error more gracefully like the error in Line 505?

Thanks!

This issue is still present in Tor Browser, is there any way to polyfill window.indexeddb?

It seems to happen on Firefox mobile in private mode as well. Maybe the APIs are simply not available. A poly fill would be great.

Unfortunately Firefox is the only browser that blocks IndexedDB in private mode instead of providing a temporary db like chrome and safari does it.

[punithbm]

Ah..Thanks for the quick response
Do you know of any alternate methods to handle this

[dfahlander]

Where your app catches errors (such as an ErrorBoundrary in React, or similary), display a friendly message that application could not be started.

Specificall, Firefox throws InvalidStateError in private mode.

https://jsitor.com/dMq2lGvOqz

const db = new Dexie("x");
db.version(1).stores({
  foo: 'bar'
});

db.open().then(()=>{
  console.log("Database successfully opened");
}).catch(err => {
  if (err.name === 'InvalidStateError') {
    console.log("Firefox private mode node supported.")
  } else {
    console.log(err);
  }
});
