MissingBrowserFeature enum

An enumeration of features not supported by the current browsers.

While this information may not be useful to end users, it can be used to understand why drift has chosen a particular storage implementation in WasmDatabaseResult.

Values

sharedWorkers → const MissingBrowserFeature

The browser is missing support for shared workers.

dedicatedWorkers → const MissingBrowserFeature

The browser is missing support for web workers in general.

dedicatedWorkersInSharedWorkers → const MissingBrowserFeature

The browser doesn't allow shared workers to spawn dedicated workers in their context.

While the specification for web workers explicitly allows this, this feature is only implemented by Firefox at the time of writing.

fileSystemAccess → const MissingBrowserFeature

The browser does not support a synchronous version of the File System API

indexedDb → const MissingBrowserFeature

The browser does not support IndexedDB.

sharedArrayBuffers → const MissingBrowserFeature

The browser does not support shared array buffers and Atomics.wait.

To enable this feature in most browsers, you need to serve your app with two special headers.

workerError → const MissingBrowserFeature

An error occurred when trying to connect to a shared or dedicated drift worker.

This either indicates a bug in drift (with the worker crashing) or an issue in your setup (for instance, this could occur when the drift worker file is missing from your web/ folder).
