download blob using dropbox Saver
Hi, I am trying to use the dropbox Saver (https://www.dropbox.com/developers/saver) to download a json blob from my desktop (ubuntu). This leads to an error: Url "blob:http://localhost:5000/f58...
- The Dropbox Saver doesn't support blobs, local files, or data URIs unfortunately, but I'll pass this along as a feature request.
Hi, I need this too in order toimplement saving to db from https://yarnspinnertool.github.io/YarnEditor/
Is there an alternative approach to blobs? I want to write a simple string from my webapp to a dropbox folder - as a text file. Is that possible or not? If so how and why is your documentation lacking a simple example?

Dropbox Staffblurymind No, the Dropbox Saver still doesn't support saving blobs, or some other local alternative. I'll add your vote to the feature request, but I can't promise if or when that might be implemented.
The Dropbox Saver only supports saving from Internet-accessible URLs. If you want to use the Saver to save a text file, you'll need to supply the data via an Internet-accessible URL.
Alternatively, you can use the Dropbox API, e.g., via the official Dropbox JavaScript SDK, to upload directly to Dropbox from the browser, but that would be more work and would require you to have the user explicitly authorize the app via the OAuth app authorization flow.
I was able to achieve creating and saving a new text file by doing this and passing it as an url to the saver:
https://github.com/YarnSpinnerTool/YarnEditor/blob/master/src/js/classes/utils.js#L278
however there is a catch. Both the saver and the chooser only function when running from the web app hosted here:
https://yarnspinnertool.github.io/YarnEditor/
Perhaps more annoyingly, the saver can not overwrite files when asked to.
Dropbox denies them both access if running from a localhost server or a hosted file. This is why I disabled it for the electron version of yarnEditor.
Wish I could use one codebase that is simple and effective to achieve saving and loading - but the current api doesn't seem to have an easy answer to this

blurymind Thanks for sharing this! Please note though that the Saver only officially supports HTTP and HTTPS URIs, so while data URIs like this may happen to work, I don't recommend relying on that. It may not work consistently, or may break without notice.
Also, yes, the Chooser and Saver do need to run on a hosted page where they can verify the domain against the pre-registered Chooser/Saver domains for the app key being used.
The Saver also doesn't currently support overwrite or other write modes, but I'll pass these along as feature request as well.
