The modern web accessed using a wide range of devices and types of network connections. Delivering a reliable experience for all of your users can be challenging.
Reliable while offline
One way of implementing reliability is the ability of your app to work without a network connection.
This is important because it makes features available in remote regions which may experience an intermittent loss of connection.
Your web app should load at a fast enough speed even when network connections are less than ideal.
Again, returning users should have the same experience on a cellular connection as they do when they’re on wi-fi. Users generally view your web app’s performance based on how it behaves in all network conditions.
Reliable is achievable
Although reliability may be challenging, modern web platforms provide technologies like service workers and Cache Storage that can make this easily achievable.
It's a journey
Web applications don’t come with that type of reliability by default. Throughout the process, you are advised to keep running audits and tests to ensure that users get the best possible experience.
