A progress bar lets someone know there’s a background task in progress.
Use progress bars for loading states that take longer than one second but avoid them for long loading processes. They’re indeterminate and don’t convey how much of the process is left. To communicate how much time is left, try the native determinate progress bar. If it’s possible to give someone an idea of the loading content’s structure, try a shimmer.
This info is coming soon We’ll add the API tables and code blocks as they become available, so check back often. In the meantime, take a look at our source and sample code in GitHub.
