AutoLabDocs ⚡

Stop wasting your life on Microsoft Word. Paste code. Get a perfect PDF. Pass the lab.

I built this because I was tired of the busywork, and now it's here to save your weekends too.

It's not just a "formatter"—it's a full-blown execution engine that runs your code, captures the output (even the graphs), and hands you a submission-ready PDF before you can finish your coffee.

🚀 Why This Rules

• Native Execution, No BS: We don't just "highlight" your code. We run it. Python, C, C++, Node.js—it all executes in a real, isolated environment.
• PDFs That Look Better Than Yours: Syntax highlighting? Check. Vector graphs? Check. Formatting that makes TAs weep with joy? Double check.
• VSCode in the Browser: The IDE experience you know and love, right there in the web app. No learning curve.
• Bulletproof Security: Every single line of code runs in a locked-down Docker container. It’s safer than your grandma’s PC.
• Traffic? What Traffic?: Our custom queue system handles load like a champ. 100 students trying to submit at 11:59 PM? No problem.

🛠️ The Stack (Heavy Hitters Only)

We didn't cut corners. We built this with the best tools available.

Frontend

• Next.js 16 (React 19): Bleeding edge. Fast as hell.
• Tailwind CSS v4: Because writing CSS files is so 2015.
• Monaco Editor: The engine behind VSCode. If it's good enough for Microsoft, it's good enough for us.

Backend & The "Secret Sauce"

• Custom Runner Service: A Node.js beast using node-pty to stream real terminal outputs via WebSockets. It's real-time, it's raw, and it's beautiful.
• Docker Isolation: Custom-built python-runner images that spin up in milliseconds and vanish just as fast.
• PostgreSQL + Prisma: Rock-solid data storage.
• JWT Auth: Secure, stateless, and scalable.

🧠 Engineering Flex (How We Handle Edge Cases)

This isn't a hackathon toy. It's built to survive the real world.

1. "Nice Try, Hackers": You can't break out. Containers run with --network none (no internet access), restricted CPUs, and capped memory. You run your logic, not a crypto miner.
2. The Queue: We implemented a smart FIFO semaphore system. If the server is full, you don't crash it—you get a ticket. We process jobs orderly, ensuring 100% uptime.
3. Garbage Collection: We clean up after ourselves. Ephemeral containers and temp files are nuked instantly after execution. The server stays lean and mean.

💻 Run It Yourself

Want to see how the sausage is made? Here is how you spin it up locally.

Prerequisites

• Node.js (v18+)
• Docker (Running)
• Postgres

Setup

1. Clone it.

   git clone https://github.com/yourusername/autolabdocs.git
   cd autolabdocs

2. Install the goods.

   npm install
   cd backend-runner && npm install && cd ..

3. Config. Create a .env file. You know the drill.

   DATABASE_URL="postgresql://user:pass@localhost:5432/autolabdocs"
   SESSION_SECRET="mash-your-keyboard-here-to-make-it-secure"

4. Database.

   npx prisma db push

5. Build the Runner. Crucial Step. You need the engine image.

   cd backend-runner
   docker build -t python-runner:latest .
   cd ..

6. Launch. Terminal 1 (Frontend):

   npm run dev

   Terminal 2 (The Muscle):

   cd backend-runner
   node server.js
