options.Modelis an instantiated interface that implements theabstract-blob-storeAPIoptions.idis a string 'key' for the blob identifier.
where input body is an object with either:
- a key
uripointing to data URI of the blob, - a key
bufferpointing to raw data buffer of the blob along with itscontentType(i.e. MIME type).
Optionally, you can specify in the body the blob id which can be the file
path where you want to store the file, otherwise it would default to
${hash(content)}.${extension(contentType)}.
Tip: You can use feathers hooks to customize the id. You might not want the
client-side to write whereever they want.
returns output 'data' of the form:
{
[this.id]: `${hash(content)}.${extension(contentType)}`,
uri: body.uri,
size: length(content)
}returns output data of the same form as create.

});Should you need to change your bucket's options, such as permissions, pass a params.s3 object using a before hook.
app.service('upload').before({
create(hook) {
hook.params.s3 = { ACL: 'public-read' }; // makes uploaded files public
}
});For a more complete example, see examples/app which can be run with npm run example.
