Because we are working on the nw.js shell project for Meituan’s takeaway merchants, we need to ensure that the data using localStorage in the shell can be persisted.
I found that nw can be saved, even if the application is deleted and rewritten and packaged, it can be saved, so this requirement is solved, but you still need to know where it is stored, otherwise it is not clear under what circumstances the data will be lost.
The localStorage storage directory of the application packaged by nw.js is:
**C:\Users\[user name]\AppData\Local\[nw application Name]\User Data\Default\Local Storage\chrome-extension_[Random characters]_0.localstorage**
For example, the location on my computer is:
C:\Users\xxcanghai\AppData\ Local\waimai_e_client_nw\User Data\Default\Local Storage\chrome-extension_blodpelipeilefodephhjbnidgkbghmj_0.localstorage
This localStorage file is a binary file and cannot be used directly A text editor opens, but can be accessed via a binary file viewer.
For example, I set a localStorage value in the nw application: xxcanghai 123

Then use the hexadecimal editor WinHex
Open the chrome-extension_blodpelipeilefodephhjbnidgkbghmj_0.localstorage file, you can view the stored xxcanghai
and 123
Firefox stores the localstorage file:webappsstore.sqlite
in the configuration file folder
Firefox (Windows XP):
C:\Documents and Settings\
