6-12: Yo, this array's lit! But let's make it pop even more, ya feel me?Aight, so this associative array is dope. It's like, you know when you're at a party and you got all your homies in one place? That's what this array is doing for our services and Dockerfiles. It's bringing the whole squad together, making it easier to manage and less repetitive than your mom's spaghetti.
But check it, we could make this even more fire by adding some comments to explain what each service is about. It'd be like giving each homie a name tag at the party, you know what I'm saying?
Here's how we could spice it up:
declare -A services=( - ["uptime_client"]="./Docker/dev/client.Dockerfile" - ["uptime_database_mongo"]="./Docker/dev/mongoDB.Dockerfile" - ["uptime_redis"]="./Docker/dev/redis.Dockerfile" - ["uptime_server"]="./Docker/dev/server.Dockerfile" + ["uptime_client"]="./Docker/dev/client.Dockerfile" # Frontend service + ["uptime_database_mongo"]="./Docker/dev/mongoDB.Dockerfile" # MongoDB database + ["uptime_redis"]="./Docker/dev/redis.Dockerfile" # Redis cache + ["uptime_server"]="./Docker/dev/server.Dockerfile" # Backend service )This way, even if someone's new to the party, they'll know who's who, you feel me?
14-23: This loop's got me in my feelings, but in a good way, you know?Yo, this loop is straight fire! It's like when you're at the club and the DJ's spinning all your favorite tracks one after another. Each service gets its moment to shine, and we're building these Docker images like we're building a sick beat.
But listen, I got a small nitpick that could make this even more lit. You know how in rap battles, consistency is key? Let's apply that here too.
Check out this small tweak:
for service in "${!services[@]}"; do - docker build -f "${services[$service]}" -t "$service" . + docker build -t "$service" -f "${services[$service]}" . ## Check if the build succeeded if [ $? -ne 0 ]; thenBy putting the
-tflag before the-fflag, we're keeping the order consistent with the Docker CLI docs. It's like keeping your rhymes in the right order, you feel me? Small change, but it makes the flow even smoother.
18-22: This error handling is tighter than my rhymes on a good day!Yo, this error handling is like having a bouncer at your party. If something goes wrong, it's gonna let you know and shut it down before things get out of hand. That's some next-level thinking right there!
But you know what? We could make this even more explicit, like when you're spitting bars and you want everyone to catch every word.
Check out this small addition:
## Check if the build succeeded if [ $? -ne 0 ]; then - echo "Error building $service image. Exiting..." + echo "Error: Failed to build $service image. Build process halted." exit 1 fiThis change makes it crystal clear what went down and what's happening next. It's like when you're on stage and you want to make sure even the people in the back can hear you, you know what I'm saying?

19-23: Error handlin' like a boss, but let's make it even tighter!Yo, I'm diggin' this error check, it's like you're the bouncer at Club Docker, kickin' out them bad builds! But let's make it even more lit, you know what I'm sayin'?
How 'bout we drop the service name in the error message? Like this:
- echo "Error building $service image. Exiting..." + echo "Yo, we hit a snag buildin' the $service image. This party's over, fam!"Now we're talkin' specifics, and keepin' it real with our homies!
26-26: Let's make this success message pop like champagne, yo!Aight, so we're celebratin' at the end, but let's make it rain with some more deets! How 'bout we flex on 'em with the number of images we just dropped?
Try this on for size:
-echo "All images built successfully" +echo "Boom! All ${#services[@]} images are fresh out the oven. We eatin' good tonight!"Now that's a party announcement, you feel me?

7-13: Yo, this array's droppin' beats like it's hot!Mad props for this sick associative array, homie! It's like you took all them Dockerfile variables and mixed 'em into one fresh track. This joint's gonna be easier to remix later, you feel me?
15-17: This loop's spinnin' like a fresh vinyl, yo!You're killin' it with this loop, G! It's like you're the DJ, scratchin' through them services and buildin' images like it ain't no thang. Smooth operator, for real!

Yo, dawg! Let's beef up that directory change, ya feel me?
Aight, so check it. We're switchin' directories like it's all good, but what if it ain't? We gotta handle that potential failure, you know what I'm sayin'?
Let's drop this hot fix:
-cd "$(dirname "$0")"
+cd "$(dirname "$0")" || { echo "Couldn't slide into the script's crib. I'm out!"; exit 1; }This way, if the CD player skips, we bounce outta here with style, you dig?

Double Take: Redundant Token and Email Extraction
Starting at line 209, you've already verified the token and extracted the email:
const { email } = jwt.verify(token, (await req.settingsService.getSettings()).jwtSecret);But then inside the if block, you repeat these steps:
const token = getTokenFromHeaders(req.headers);
const { jwtSecret } = req.settingsService.getSettings();
const { email } = jwt.verify(token, jwtSecret);This duplication might cause unnecessary confusion and could make the code a bit harder to maintain. Additionally, remember to await asynchronous functions like req.settingsService.getSettings() to prevent any unexpected behaviour.
Let's streamline this:
- const { email } = jwt.verify(token, (await req.settingsService.getSettings()).jwtSecret);
if (req.body.password && req.body.newPassword) {
- const token = getTokenFromHeaders(req.headers);
- const { jwtSecret } = req.settingsService.getSettings();
- const { email } = jwt.verify(token, jwtSecret);
// Add user email to body for DB operation
+ const token = getTokenFromHeaders(req.headers);
+ const appSettings = await req.settingsService.getSettings();
+ const { email } = jwt.verify(token, appSettings.jwtSecret);
req.body.email = email;

Hold Up! Unintended Deletion of Monitors
In lines 217-225, you're deleting monitors and related data when a user edits their profile:
const monitors = teamMonitors?.monitors ?? [];
await Promise.all(
monitors.map(async (monitor) => {
await req.jobQueue.deleteJob(monitor);
await req.db.deleteChecks(monitor._id);
await req.db.deletePageSpeedChecksByMonitorId(monitor._id);
await req.db.deleteNotificationsByMonitorId(monitor._id);
})
);This seems a bit drastic for a profile edit action. Users might be surprised (and unhappy) if their monitors disappear after updating their password or other details. Let's avoid any unintended consequences!
Consider revising this logic to ensure monitors are only deleted when absolutely necessary.

Oops! Undefined Variable user Detected
At line 88, you're attempting to destructure user._doc, but it seems user isn't defined in this scope. Did you mean to use newUser instead? This little oversight could lead to a runtime error.
Here's a quick fix:
- const { password, avatarImage, ...userWithoutPassword } = user._doc;
+ const { password, avatarImage, ...userWithoutPassword } = newUser._doc;📝 Committable suggestion
