File uploads in loopback

[Abbas Mousavi]

Loopback  documentation (http://docs.strongloop.com/display/DOC/LoopBack) says: "...  apps can upload files" and recently a class named LBFile has added to iOS client, but there is no documents about uploading files.

1 - Can I define a "file" field in my loopback model?

2 - Can I upload files using Javascript client?

3 - Can I choose to store files on file system or database?

The file/storage service and SDK APIs are yet to be released. We’re working on tidying up the features, testing the functions, and documenting the APIs. Stay tuned.

For a quick preview, the upcoming release for the file/storage service will consist of a few components:

1. A Node.js that is integrated into the LoopBack applications that allow you to upload/download files/blobs to/from various storage systems, such as file system, Amazon S3, Rackspace cloud files. The providers are pluggable. You can write your own too. It also manages the metadata as container/file objects.

2. LBFile APIs in the iOS and Android SDKs.

3. The file/storage service is exposed as REST APIs. The upload protocol is based on multipart/form-data mime type over HTTP, which is the one that browsers support for the file fields. The JavaScript can use the HTML5 file upload library too.

Thanks,

Raymond

Hi,

I just made https://github.com/strongloop/loopback-storage-service public. Feel free to check it out for preview. Please be aware that the module has NOT been officially released. 

There are examples under the example folder. You can use them as the starting point. 

Feedbacks are welcome.

Thanks,

Hi,

I'm really interested in file upload from AngularJS.


I've spotted these plugins for Angular:

https://github.com/danialfarid/angular-file-upload

https://github.com/nervgh/angular-file-upload

But I don't have any idea in how manage this on the server-side with Loopback.

Is Loopback-storage-service released? Coud I make it work with the client plugins linked above?

Thanks

FWIW, there is a GitHub issue requesting a first-class support for files and containers in the LoopBack SDK for AngularJS:

  https://github.com/strongloop/loopback-sdk-angular/issues/22 

Although it was not our priority so far.

Struggling with the same issue. Could you pls provide what kind of solution you ended up with?

Created a stackoverflow ticket: http://stackoverflow.com/questions/28885282/loopback-uploading-a-file-and-store-it-with-meta-data

So we can have this solved once and for all.

The example 2.0 is pretty helpful. I also created a gist of the bare minimum I needed to do to get file upload working with `ng-file-upload`, because I was struggling for a bit to figure it out: https://gist.github.com/reichert621/e987545fdbc2bc071d37

Hi Raymond,

Using this loopback component I able to upload file with in a folder inside of a bucket. But I am not able to download a file from a folder. Please suggest a way around...

[Raymond Feng]

GET /api/containers/myContainer/files/myFile should do.
