This diff adds lazyWithRetry utility function to mitigate loading chunks errors.
We can see this error when try to dynamically load module, for example using react router with React.lazy.
Typically, every module has hash in its name like
[name].[hash].js
.This hash helps to understand that module was updated.
We do the above to make the browsers aware of the code change, that is good for the times when users are not online and will come back after we deploy a new version while online users still are imminent to the issue we’ve proposed.
If the page is stale for some period of time, and files are updated on the server, the name of the module actually is getting outdated. Frontend knows about
module.xxx.js
, but we already havemodule.yyy.js
. When user tries to navigate the route wit that module, the error will be thrown.
