The CRUD Trap: Why Most Web Apps Fail Before They Even Start (And How to Avoid It)

Introduction

As a budding backend developer, I embarked on a project that I initially thought would be a straightforward web app. Armed with Node.js, Express, MongoDB, and JavaScript, I dove in headfirst, eager to bring my idea to life. Little did I know that this journey would teach me a critical lesson about the importance of planning in backend development.

The Unplanned Path

When I started, I was confident in my ability to handle CRUD operations. Creating, reading, updating, and deleting data seemed simple enough.

However, as I progressed, I found myself constantly changing and deleting database schemas and values to accommodate new updates. Each change felt like a step forward, but also a reminder of how my lack of planning was catching up with me.

My approach was reactive rather than proactive. Instead of anticipating and planning for future requirements, I only made changes when problems arose. This led to a lot of inefficiencies and frustration, as each new feature required significant modifications to the existing schema.

The realization hit me hard: backend development is not just about writing code; it's about building a robust and scalable foundation.

The Turning Point

One particularly daunting night, after countless schema revisions, I realized I was stuck in a cycle of inefficiency. I decided to step back and re-evaluate my approach. I needed a plan—a comprehensive understanding of the whole system, anticipating future requirements, and designing a schema that could accommodate growth and change.

Lessons Learned

Here are the key lessons I learned from this experience:

1. Think Ahead: Before writing a single line of code, spend time understanding the project requirements. Consider the features you plan to implement and think about how they will interact. Draft a comprehensive schema that can evolve with your project.
2. Normalization and Optimization: It's not enough to just store data. Efficiently structuring your database is crucial. Normalize your data to reduce redundancy and ensure consistency. Optimization should be an ongoing consideration, not an afterthought.

1. Flexibility in Design: While planning is essential, it's also important to design your system to be flexible. Future changes are inevitable, so build your schema in a way that can handle modifications without extensive overhauls.
2. Documentation: Keep thorough documentation of your database schema and the rationale behind its design. This not only helps you stay organized but also aids others who may work on your project.
3. Testing and Iteration: Regularly test your schema with sample data and use cases. Iteration is part of the development process, but with a solid plan, these iterations will be more about refinement than complete overhauls.

A New Approach

Armed with these insights, I revisited my project. I sketched out the entire system, considering not just the current requirements but also potential future expansions. This time, I built a database schema designed for efficiency and scalability. The process was smoother, and the end result was a web app that not only worked but was also easy to maintain and expand.

My Project: Student Result Checker

Allow me to introduce the project that sparked these valuable lessons: a Student Result Checker system. This application features a comprehensive role-based system with admins, class teachers, and subject teachers.

• Admin: Manages the entire system, including user roles and global settings.
• Class Teacher: Manages a specific class and its students, overseeing their performance.
• Subject Teacher: Manages particular subjects assigned to them, entering and updating student results.

This project has been an incredible learning experience, and I’m excited to share its final release with you soon. Stay tuned for updates, and I hope you find it as useful as I’ve found it challenging and rewarding to build.

Final Thoughts

As backend developers, our role extends beyond just writing code. We are the architects of the systems that power applications and a well-thought-out plan is our blueprint. My journey with Node.js and MongoDB taught me that planning is not a luxury but a necessity. It transforms a daunting process into a manageable one and turns frustration into fulfillment.

Remember, it's not about how quickly you can code but how effectively you can design. Take the time to plan, and your future self will thank you.
