Firebase Environments

Last updated: October 21st, 2019.

At the time of writing this gist (January 4th, 2017), I was unable to find true sandboxing to separate development and production environments for a Firebase project. The closest we can get is to create two separate Firebase projects -- one for development and one for production.

Pros

• Complete separation and isolation of all Firebase features.
• Freedom to experiment without risking the corruption of production data.

Cons

            // Look for specified image duration; always prefer unclamped delay time
            guard let properties: [String: Any] = (properties as? [String: Any])?["{GIF}"] as? [String: Any],

// This script loops though the list of collection names in a MongoDB and runs the compact operation on them
// Simply paste this into the Mongo shell

use testDbName;
db.getCollectionNames().forEach(function (collectionName) {
    print('Compacting: ' + collectionName);
    db.runCommand({ compact: collectionName });
});

A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...
