Where to get data to validate file? about react-s3-uploader

[seanadkinson]

What kind of data are you wanting to validate, and how? If you are trying to validate the uploaded file, you would need to download the file from S3 and validate. Make sense? Let me know if I don't understand your use case. Thanks.

I want to do something like explained here: http://stackoverflow.com/questions/8903854/check-image-width-and-height-on-upload-with-javascript

If I had access to the file, I could use a local URL of the image and, therefore, be able to validate it before uploading to s3.

I see. We had a PR for adding files to callbacks, but the author hasn't fixed it up yet.

I just created and pushed a branch named callback-files with the desired behavior from that PR. Basically all the callbacks get the file as the last argument.

Try referencing this branch from your package.json like so:

"react-s3-uploader": "odysseyscience/react-s3-uploader#callback-files"

Let me know if that gives you what you want, and I'll see about pushing an update.

The callback-files branch works perfectly. Thanks so much, Sean! 😄
