Graphql relay array field

I am starting to develop for relay coming from Apollo. I have a dumb server running on a SQLITE3 database just for testing while I am refactoring. Using graphql-relay on the backen.

Currently I have something like this:

{
  root: {
    allFoo: [FooType]
  } 
}

I was wondering how I would add a new FooType item to the allFoo list. On the getConfigs the RANGE_ADD only acts upon connections. So do I need to make my allFoo type a connection instead of a GraphqlList(FooType) ? Or can I use FIELD_CHANGE somehow?

Take a look at this example: https://github.com/bfwg/relay-gallery/blob/master/frontend/src/app/mutation/AddImageMutation.js#L47

The below example is a demo on how to add an image to the image list.

getConfigs() {
  return [{
    type: 'RANGE_ADD',
    parentName: 'User',
    parentID: this.props.images.id,
    connectionName: 'images',
    edgeName: 'newImageEdge',
    rangeBehaviors: {
      '': 'prepend',
    },
  }];
}

Hope this helps!
