exfiltrate groove basin database to a JSON file

README.md

1. drop db2json.js into your groovebasin instance
2. stop your groove basin instance so that it does not write to the db while you are dumping its data
3. node db2json.js (use the same node.js version as groove basin is using, and it also wants to use the same leveldown dependency you already have installed). It hard-codes the input as groovebasin.db.
4. groovebasin.db.json is created which is 100% of the information from the database, in JSON format. It is one giant map of every key-value pair.

db2json.js

var fs = require('fs');
var path = require('path');
var leveldown = require('leveldown');

var defaultConfig = {
  dbPath: "groovebasin.db",
};

main();

function main() {
  var dbFilePath = "groovebasin.db";
  var db = leveldown(dbFilePath);
  db.open(function(err) {
    if (err) throw err;

    dbIterate(db, "", processOne, allDone);

    var map = {};

    function processOne(key, value) {
      map[key] = value;
    }

    function allDone(err) {
      if (err) throw err;
      fs.writeFile("groovebasin.db.json", JSON.stringify(map), function(err) {
        if (err) throw err;
        process.exit(0);
      });
    }

    function deserializeUser(payload) {
      return JSON.parse(payload);
    }
  });
}

function dbIterate(db, keyPrefix, processOne, cb) {
  var it = db.iterator({
    gte: keyPrefix,
    keyAsBuffer: false,
    valueAsBuffer: false,
  });
  itOne();
  function itOne() {
    it.next(function(err, key, value) {
      if (err) {
        it.end(onItEndErr);
        cb(err);
        return;
      }
      if (!key || key.indexOf(keyPrefix) !== 0) {
        it.end(cb);
      } else {
        processOne(key, value);
        itOne();
      }
