在Web中将目录的递归副本复制到Cordova中的设备文件系统

Question

I want copy all files in a web directory on a webserver, and ideally in its component subdirectories, into local device storage for Android and iOS in Cordova using javascript and/or cordova plugins.

The use case is to copy an entire (smallish) webapp/page from a remote webserver (that we control, and where we posted the content) into local storage on the device. This will be used for a form of hot code push for a cordova app.

It's possible to copy files using cordova-plugin-file-transfer:

https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/

or in a more standards-compliant way using XMLHttpRequest (XHR):

https://cordova.apache.org/blog/2017/10/18/from-filetransfer-to-xhr2.html

How does one copy an entire directory tree, overwriting an existing one, in device storage.

Preferable: method to include error handling for the case that something prevents the full copy from happening, possibly resulting in a partial copy or a corrupted directory.

Is there an api or combination of apis that do this already? If not, does someone have or know of code to accomplish this?

Thanks!

You can look at hydration of phonegap for hot push :

I think it may be suitable for your need.

However, be very careful with hot code push because apple doesn't like it very much and it's rather contrary to their guideline.
