How can I cache a csv for Papa Parse to parse?

The browser and server you're downloading the CSV file from should negotiate caching for you; I might misunderstand but I'm not sure what Papa Parse would have to do with that.

For last modified date, if the file happens to be selected by the user with a <input type="file"> element on the page, you can access the File object and check its lastModified or lastModifiedDate properties (at least, they exist on Chrome).

To get the last modified date of a file to be downloaded, MDN has an example all ready for you:

function getHeaderTime () {
/* A valid GMTString date or null */

var oReq = new XMLHttpRequest();"HEAD" /* use HEAD if you only need the
headers! */, "yourpage.html", true);
oReq.onload = getHeaderTime;

This simply does a HEAD request (to only check the last-modified and not get the whole file, all you need is the headers) and reads the Last-Modified header.

I would suggest creating two new tables to capture swipe interactions. Something like: Liked - initiatingUser - likedUser Unliked - initiatingUser - unlikedUser And then every time a user swipes right or left, add a new record to the proper table. Then I would use the AfterSave functionality of Cloud Code to perform a fetch of the Liked table where the initiatingUser and likedUser are flipped
