polarisation / indexeddb-export-import Goto Github PK

I'm trying to save a copy (whether JSON or some other format) of a third-party's site's indexedDB. Is that something that this library could help with? If so, what's a rough sketch of how to do that?

This may be a very naive question but index creation is very slow for me and I have a large (400k+) table with a few indexes. Following the examples I am still getting the browser creating indexes internally (which use a lot of CPU and take several minutes, so it is very visible), so it appears this project doesn't do that. I would have been very surprised if it could do this but if you don't ask you will never know!

I have a requirement to take a backup of indexed database from the browser. Can you please point me to a place that explains this or give me some pointers of how to use this library to run the backup from a browser.

ArrayBuffer should be exported via some tricky way instead of JSON.stringify.

Hi,

When trying to bundling my project with webpack and UglifyJs I get the following error:

ERROR in static/js/vendor.a27e424093e8687946a1.js from UglifyJs
Unexpected token: name (count) [./node_modules/indexeddb-export-import/index.js:50,0][static/js/vendor.a27e424093e8687946a1.js:51531,6]
...

We are trying to converting our Web App into an Electron APP.
We use DexieJS in our Web App, so we prefer to use it as well in our Electron APP.

However, we are worried about the data safety, since there are maybe some scenarios, the data inside indexedDB MIGHT be deleted. Such as reinstall the App, auto update the App etc. We are not sure about it. But we can not risk it.

I found this project while searching around the internet. I am wondering maybe this could be used to backup the indexedDB.

Is this possible?
Thanks.

Example provided uses exportToJson but the method inside the package is exportToJsonString
applicable for importFromJson as well

I'm saving sets to my database, eg new Set() and while they show as a Set in the indexeddb inspector, they appear as empty objects {} in the exported JSON.

Something like this in the Chrome inspector:

{
  items: Set(12)
}

becomes:

{
  "items": {}
}

When importing a backup into a browser that didn't have an existing database I get the following error:

Uncaught DOMException: Failed to execute 'transaction' on 'IDBDatabase': The storeNames parameter was empty.

This is due to idbDatabase.objectStoreNames being an empty list in

  const transaction = idbDatabase.transaction(
      idbDatabase.objectStoreNames,
      'readwrite'
  );

Any help would be appreciated!
