Most of the cloud services provide API to fetch their data. But data will be given as paginated results as returning the complete data will overshoot the response payload. To discover the complete list of books or e-courses or cloud machine details, we need to call the API page-wise till the end. In this scenario, we can use Spring Batch to get the data page by page and dump it into a file.

While developing web applications, we built many components and having a data model across the application wide model will be difficult. We need common store management to update and get information across all the components. In React based Web UI, redux is the official centralized state management to be used which is internally wired as state changes to the component. There are other alternatives to redux which are light-weight and simple to use. One among them is Jotai, a minimalistic API for state management. In this blog we will take one of the redux examples given in the redux site and do the same in Jotai for deeper understanding.
