This takes the uppy chunking algorithm and combines it with some
form submission from resumable.js for parity with the current
backup controller to make local backup uploads work with uppy.
We can then use this to replace the resumable-upload component
and the resumable.js library from our codebase, once stable.
This is disabled by default, so people using local backups will not
be affected. The enable_experimental_backup_uploader site setting
must be enabled for this to work.
Uppy V2 includes the S3 multipart batch presigning change
we contributed in d613b849a6
so we need to upgrade it. This also brings both package.json
files into line and accounts for the renaming of Plugin
to BasePlugin in Uppy.
This has been tested and is working locally for both
regular Ember and Ember CLI, for uploads.json
XHR uploads and for direct S3 uploads (single and multipart).
This PR adds the first use of Uppy in our codebase, hidden behind a enable_experimental_image_uploader site setting. When the setting is enabled only the user card background uploader will use the new uppy-image-uploader component added in this PR.
I've introduced an UppyUpload mixin that has feature parity with the existing Upload mixin, and improves it slightly to deal with multiple/single file distinctions and validations better. For now, this just supports the XHRUpload plugin for uppy, which keeps our existing POST to /uploads.json.
This PR adds uppy to the project with a custom JS build and the shims needed to import it into our JS code. We need a custom build of Uppy because we do not use webpack for our JS modules/build. The only way to get what you want from Uppy is to use the webpack modules or to include the entire Uppy project including all plugins in a single JS file. This way we can just use the plugins we actually want. Future PRs will actually use Uppy!
