Add method for getting list of documents (as objects) from a collection

Currently, if you want to get a list of all documents (as JSON objects) from a collection, you have to

1. Call getDocumentIds(pathToCollection, email, key, projectId) to get the IDs for the collection
2. Loop through these IDs and combine the pathToCollection with the ID to make the document path.
3. Call getDocumentFields(path, email, key, projectId) for each document ID / path to get a JSON object for that document.

This should be combined into a single method.

Hey @grahamearley, we recently did a Hackathon and added query support to this library. I’ll hopefully send a PR with this functionality soon, and it will allow you to get multiple documents from a collection easily. This has the big advantage of doing a single URLFetch instead of O(n) URLFetches.

Right now, I’m thinking the method call will look very much like the “get” method, but will have a param called “query” instead of “path” that will be a Firestore StructuredQuery.

I’m thinking it will look something like this:

query(query, email, key, projectId) {
  query_(query, email, key, projectId);
}

getAllDocuments(path, email, key, projectId) {
  var query = {
    from: [{collectionId: path}]
  };
  query_(query, email, key, projectId);
}

query_(query, email, key, projectId) {
  // Code to Query and Return Documents
}
