How do I structure Cloud Functions for Firebase to deploy multiple functions from multiple files?

by

I would like to create multiple Cloud Functions for Firebase and deploy them all at the same time from one project. I would also like to separate each function into a separate file. Currently I can create multiple functions if I put them both in index.js such as:

exports.foo = functions.database.ref('/foo').onWrite(event => {
    ...
});

exports.bar = functions.database.ref('/bar').onWrite(event => {
    ...
});

However I would like to put foo and bar in separate files. I tried this:

/functions
|--index.js (blank)
|--foo.js
|--bar.js
|--package.json

where foo.js is

exports.foo = functions.database.ref('/foo').onWrite(event => {
    ...
});

and bar.js is

exports.bar = functions.database.ref('/bar').onWrite(event => {
    ...
});

Is there a way to accomplish this without putting all functions in index.js?
