How to Upload Attachments via the BULK Api?

While I can upload attachments just fine via CRUD, I have to upload about 1000 files - which would be insane to do via REST api.

I’m trying to do it with the BULK api, but I get this dread error: “Binary field Body is only supported for content types ZIP_XML and ZIP_CSV”.

Setup

var bulkInsert = function(sObject, records) {
    return new Promise(function(resolve, reject) {
        console.log('>>> Starting batch insert of', records.length, sObject, 'records ...');
        sfConn.bulk.load(sObject, 'insert', records, function(err, results) {
            if (err) {
                reject(err);
            } else {
                resolve(results);
            }
        });
    });
};

Method #1:

bulkInsert('Attachment', [{
    ParentId: 'someSFId',
    Name: 'myImage',
    ContentType: 'image/jpeg',
    Body: Buffer(fs.readFileSync('/path/to/my/files'), 'binary').toString('base64')
}];

Method #2:

bulkInsert('Attachment', [{
    ParentId: 'someSFId',
    Name: 'myImage',
    ContentType: 'image/jpeg',
    Body: '/path/to/my/jpg'
}];

They both fail with Binary field Body is only supported for content types ZIP_XML and ZIP_CSV.

However, the REST api works just fine …

sfConn.sobject('Attachment').create({
    ParentId: 'someSFId',
    Name: 'myImage',
    ContentType: 'image/jpeg',
    Body: Buffer(fs.readFileSync('/path/to/my/files'), 'binary').toString('base64')
});

How can I get the BULK api to work as well?

@kylefarris If you already have a fork implementation please give us the PR and we would like to check if it is suitable for merge to master.

I’m working on this feature in my fork (read: I actually have it working). It’s really not that complicated to implement. I was just wondering how much of the functionality (zipping, etc…) should be incorporated into jsforce itself vs just showing how to do it in the documentation. The changes to jsforce itself were relatively minor (just allowing a user to choose the contentType), but if we wanted to have the full zipping capability built into the library, that would be a lot more extensive and would require a couple new dependencies (adm-zip and streamifier).

I’d like some thoughts from the jsforce team before making my pull request.
