A full-stack web application that conducts pretrips digitally & overlays the data onto a PDF. The core functionality works for guest users and the application is completely free for all users. Users may create an account to store their Driver Vehicle Inspection Reports into MongoDB. Documents that are securely stored with MongoDB can be searched and filtered by the owner of the documents. The code is open source so you can see what data is being collected and know that user-privacy and transparency are values I build by. This site is viewable across mobile-view ports and is deployed live on Railway.
Deployed on Railway: https://pretriq.com/

This project has shown me that learning & understanding is displayed through building. There are several features I have seen for the first time. I had to learn more about it and implement in a way that fits the codebase in this project. I experienced an undescribable feeling where I have watched this project grow from a blank page to where its at now. It came a long way and there is still so much more that can be added and improved on. I envision that this application has potential to become something with a global reach.

📢 Developer's Notes - I got obsessed with optimizing my google lighthouse score to the point where I broke stuff
-
Database is fine and no rollbacks there
-
I rolled the site back to June 28th, 2025.
- Everything should be at its most stable point (version after tests)
-
This project will have less updates unless I receive feedback to implement a feature

7-day Analytics update:
📅 Release Date: June 28, 2025
- I'm sorry to anyone who was effected by this. I ran a command before making a test database. Data was overwritten.
- I lost about a week of pretrip documents
📅 Release Date: June 28, 2025
📢 Developer's Notes - E2E testing, creating a test database&cluster, running test suites for Unit testing(controllers,middleware,models,routes), Integration(models) & E2E(views/viewsW/DB)
- Testing an application is no joke. It's basically rewriting the app three times over!
- This is a small web too with not that many featuers.........
- pretriq is now production-ready
Every test suite being tested at once. All tests pass. 🚀Pretriq is production ready🚀
All unit test pass across controllers, models, routes, middleware, and client-side JavaScript. All integration tests pass with (test)database connectivity. All E2E tests pass with with (test)database connectivity
📅 Release Date: June 27, 2025
- I created a unit test for a single controller's function
- Then I created unit tests for every function on that controller
- Then I created unit tests for every controller, and their functions
- Imagine my face when realizing it's best practice to test every. single. function that a controller has
- Then I created unit tests for every controller, and their functions
- These tests check a function's logic, checks if it's handling errors and branching them correctly, checks if the correct response is being sent, checks if it's calling the right model
- Then I created unit tests for every function on that controller
- I created a unit tests for every model and every schema
- Check for validation rules, default values and custom methods

- I have not refunded the SSL from NameCheap -- lose money
- Turns out Railway automatically certifies deployed websites/apps with SSL if it has a custom domain
- I actually was developing the card section on the night of the 25th, but fell asleep on the floor
- Newsletter section is now a functional contact us form with Nodemailer
- Users who send a message through the contact form receive an automated email response from pretriq
- I also receive an automated email response from pretriq notifying me about your feedback

- Newsletter section is now a functional contact us form with Nodemailer
- The two incoming/outgoing emails have templates. I styled these templates. Bro. web dev goes so deep. Looks professional tho.
- Not bad for only putting a small amount of time into it after just making it for the first time
Incoming emails (user feedback to me):
Outgoing emails (pretriq to user)
📅 Release Date: June 25, 2025
📢 Developer's Notes - Fixed bug w/ PDF download on mobile, Profile page optimizations, Hero section update-- canvas & hero image, Tackling guest-user-flow
-
When the "download official pdf" button launched it was intended as a "View" button vs a download. Mobile users couldn't view it, but desktop users could. I figured to use the solution that can solves for both
-
Registered users can view the optimizations to the profile page
-
Big visual updates to the hero-section for our landing page
- Used canvas API to display bouncing letters over the screen
- You ever watch cartoons and get the joke later in life? Yeah same, but with my on-demand-background-picker project. It even says it in the title
- I used ChatGPT to describe the image as a prompt then used the prompt on an AI image generator. Came out solid
- Used canvas API to display bouncing letters over the screen
-
When I first tackled guest user flow, my mistake was not creating the functionality/foundation for authenticated users first. Building that first allowed me to easier visualize how to approach this problem
- The new approach lets the user submit an inspection and stores it locally to their device. The user is prompted to download their data then create an account, or continue as a guest. Modal text stating that local data is not stored and to save your documents by downlading. End.
- The old approach lets the user submit an inspection and stores it locally to their device with a guestId. The user is prompted to create an account or continue as a guest. Edge cases introduced:
- If user wants to continue as a guest, what am I comparing the guestId to? Nothing in the server to compare it to, since guestId is generated locally.
- Create something to compare it to
- should've stopped here but I went on for a few more hours
- Create something to compare it to
- If user wants to sign up, they are now expecting their report to be stored after the account is created
- Create a conversion function to transform locally stored data into data that is accepted by our database schema then moved into MongoDB
- Works, but did not solve guestId/session storage problem, so the time invested here was for fun
- Create a conversion function to transform locally stored data into data that is accepted by our database schema then moved into MongoDB
- If user wants to continue as a guest, what am I comparing the guestId to? Nothing in the server to compare it to, since guestId is generated locally.
Here's the keep it simple version:
📅 Release Date: June 24, 2025
📢 Developer's Notes - Using jsPDF & html2canvas, sanitize sanitize sanitize, adding confetti, updating profile page
- learning how to programmatically display text with jspdf was fun - definitely see this being used in real worlds situations
- I am validating and sanitizing any thing possible, I want this app to be secure
- confetti now shows up when completing an inspection!
📅 Release Date: June 23, 2025
📢 Developer's Notes - serving error code 404 & 500 pages, visualizing data with Google Analytics, deciding on pretriq logo, adding social media links, using semantic HTML
- I didn't know your server had to serve 404 and 500 status code pages
- Using Google Analytics to collect data was surprisingly very easy to implement
- I added my social media links if any users want to give feedback on how to improve the app or bring bugs to my attention
I picked the logo that looked like eyes
📅 Release Date: June 22, 2025
📢 Developer's Notes - creating pre-trip reports digitally, optimizing, validating & sanitizing, displaying dynmic content, newsletter functionality
- The code I pushed on this day was extremely productive. I decided to put a pin in Guest-User-Flow and focus on the authenticated side. We skipped about .6 version numbers, and that is because the Minimum Viable Product stage has been achieved.
- This full-stack web application is deployed live on Railway and can support users with account creation. The main functionality is tucked away in a member's-only area (for now) where free users can conduct a Driver's Vehicle Inspection Report digitally. This report is saved to the user's account and securely stored on the MongoDB Database. More features and user-interactivity will be coming as I intend to use this web application.
- The modal with the pretrip report is on POST route and I have validated and sanitized the input using the express-validator library.
- The member's-only area now displays dynamic content and shows your documents that's stored in MongoDB.
- The newsletter works, so if you enter an email in there, that gets saved into the database too.
- I moved all my client-side javascript away from my HTML so stuff should be smoother/faster.
- I also cleaned up a lot of unused controller functions on the server side.
Well. There's still so much I want to build for this project, so stay tuned
📅 Release Date: June 21, 2025
- The code I pushed on this day was not productive.
- I spent several hours doing pseudocode, building & debugging. I ended the night by deleting everything I had just spent more than half the day working on. I was working on creating a Guest-User-Flow which allowed a non-authenticated user to conduct a pre-trip inspection report. The user would submit the report and be prompted to either create an account or continue as a guest. This is where all the pseudocode & theory craft came in. I decided to use session storage to store guestId token after the user completed a report. Even if the user decided to signup at the prompt or later, the backend logic would search for the token if it existed and compare it. Also the document which represents stored inspection reports was not being stored in my collection.
I'd solve one thing and three more thing would arise. I rage quit.
Here are some images of my Guest-User-Flow:
📅 Release Date: June 17, 2025
- The code I pushed on this day was front-end heavy.
- During the pandemic, I visited a local businesses website and saw a button on their webpage-- yup you guessed it, the button had a rotating gradient ring border. Looked exactly like RGB lights flowing clockwise around a button. I didn't copy the exact code, but copied the concept.
- The previous newsletter section I made was actually an image. It wasn't even styled. Just an input element with a image behind it. I thought it looked good.
- I optimized the app by removing unused code and added ARIA label/roles to assist with screen reader accessibility.
📅 Release Date: June 16, 2025
📢 Developer's Notes - change bo-tow name & domain name to pretriq, sunset Quagga2 idea, try new idea-- digital pre-trip inspections
- The code I pushed on this day was minor.
- Mainly changed the name from bo-tow to pretriq.
- This web application initially began as an idea to create an "Uber" for tow truck operators to do gig work and perform roadside assistance for users. The scope of this project is bigger than I could ever imagine.
- I wanted to create an application that I could use for work.
- My idea was to make an inventory management system with scanner functionality using Quagga2.
- It worked but it was not practical IRL and made inventory take longer.
- My idea was to make an inventory management system with scanner functionality using Quagga2.
📅 Release Date: June 12, 2025
📢 Developer's Notes - local environment setup, install validator, update User schema, re-deploying on Railway, updating local-auth to resume sign ups, and play with Quagga2
- The code I pushed on this day was mainly to get the website back online.
- Everything was broken and I started with fixing bugs with account creation and storing the newly-created account into MongoDB.
- I revived this web application with the intention to make it as secure as I have learned--
- so I used the validator library to validate email during signup.
- I temporarily named the domain "whwh".
