I'm interested in finding out whether Puppeteer can be used to save sessionStorage and localStorage data to a disk for future reuse. Specifically, I would like to know if it's possible to persist key-value pairs from these storage objects so that they can be reloaded during subsequent sessions or automated tests. Are there any established methods or workarounds for managing this data persistence reliably with Puppeteer? My goal is to streamline data management between different execution cycles.
I have encountered a similar challenge in one of my projects where persistent storage was essential for multi-session testing. In my setup, I overcame Puppeteer’s lack of inherent persistence by extracting both localStorage and sessionStorage data as JSON during the script execution and writing it to a file on disk. During subsequent sessions, I would read this file and programmatically set the storage values using page.evaluate. This manual approach was reliable and, although it required extra coding, it streamlined test initialization and minimized repetitive login or setup procedures.
In my experience, it is feasible to save and restore sessionStorage as well as localStorage data by injecting customized scripts into the browser context using Puppeteer. I implemented a solution where a simple script captures storage data as an object and writes it to a JSON file. For subsequent sessions, the same approach reads the saved file and repopulates both storage types through page.evaluate. This method proved effective over multiple runs, ensuring that session state is maintained without manual intervention between tests.
hey, i tried a hack dumping both storages as json then reloading 'em via page.evaluate on startup. it ain’t perfect but works good for basic tests. timing can be tricky though, so keep an eye on that. cheers!
