What is the most efficient way to retrieve a document from pouchdb that includes the revision attribute?

I am currently developing an application using the electron framework and integrating pouchdb. As certain values in my database are dynamic and constantly changing, I am looking for a way to track these changes without having to create new documents for each update. I believe utilizing revisions, which are generated with each update, would be the optimal solution.

My main query is regarding how to retrieve a specific document solely based on its revision number.

Any assistance on this matter would be greatly appreciated. Thank you in advance.

Answer №1

After much perseverance, I finally cracked the code and found the solution to my issue. I want to share my resolution here for the benefit of others facing a similar dilemma:

var db = new PouchDB('./test20');  // initializing the database

/* By invoking the changes() function, I can retrieve specific changes 
   associated with a particular ID */

function changes() {
  console.log("Currently in: changes()");
  var playerID = "" + localStorage.getItem("playerIDLocalStorage");

  db.get(playerID, { revs_info: true }).then(function (revs) {
    var x = 0;

    while (revs._revs_info[x].rev != null) {
      var revision = "" + revs._revs_info[x].rev;

      db.bulkGet({
        docs: [{ id: playerID, rev: revision }],
        include_docs: true
      }).then(function (result) {
        var doc = result.results[0].docs[0].ok;
        console.log(doc.playerName);
      }).catch(function (err) {
        console.log("Error in subchanges(): " + err);
      });
      x++;
    }
  }).catch(function (err) {
    console.log("Error in changes(): " + err);
  });
}
