๐Ÿš€ DevScope โ€” Understanding Your Codebase Dependencies Like Never Before

In large projects, dependencies grow quickly.

Because of reusable components, shared utilities, and modular architecture, it becomes hard to answer a simple question:

๐Ÿ‘‰ โ€œIf I change this file, what else will it affect?โ€

I faced this problem multiple times while working on real projects.
So I decided to build something to solve it.

Thatโ€™s how DevScope was born.

๐Ÿงฉ The Problem

As projects scale:

Files become interconnected
Imports grow complex
Refactoring becomes risky

Even a small change can break multiple parts of the applicationโ€”and you may not even realize it.

๐Ÿ’ก The Solution

DevScope is a lightweight CLI tool that:

Builds a dependency graph of your project
Tracks relationships between files
Identifies impacted files instantly
โšก Getting Started

Install globally:

npm install -g @maheshdev/dev-scope

Run inside your project:

dev-scope analyze

This generates a clean dependency tree:

src/index.ts
  โ”œโ”€โ”€ src/commands/overview.ts
  โ”œโ”€โ”€ src/commands/impact.ts
  โ””โ”€โ”€ src/commands/analyze.ts
Enter fullscreen mode Exit fullscreen mode

๐Ÿ” Impact Analysis

Want to know what breaks if you change a file?
dev-scope impact <file_name>

dev-scope impact src/graph/buildGraph.ts

Output:

Affected:
  โ”œโ”€โ”€ src/commands/analyze.ts
  โ”œโ”€โ”€ src/index.ts
  โ”œโ”€โ”€ src/commands/impact.ts
  โ””โ”€โ”€ src/commands/overview.ts
Enter fullscreen mode Exit fullscreen mode

This is extremely useful before refactoring.

๐Ÿ“Š Project Insights

You can also run:

dev-scope overview

This gives insights like:

Total files & dependencies
Leaf files (no dependencies)
Most used files
Unused files
Enter fullscreen mode Exit fullscreen mode

๐Ÿง  How It Works (Simplified)

At its core, DevScope uses two main ideas:

  1. Dependency Graph

Each file is treated as a node.
Imports between files create edges.

Example:

A โ†’ B โ†’ C

This means:

A depends on B
B depends on C

  1. Reverse Traversal (DFS)

To find impacted files:

Start from the changed file
Traverse backwards through dependencies
Collect all files that depend on it

This is done using Depth First Search (DFS).

๐ŸŽฏ Why I Built This

While working on projects, I often struggled with:

Understanding large codebases quickly
Safe refactoring
Identifying unused files

I wanted something:

Simple
Fast
No UI overhead
Just works in terminal
โš™๏ธ Tech Stack
TypeScript
Node.js
Commander (CLI)
๐Ÿš€ Try It Yourself
npm install -g @maheshdev/dev-scope

Start exploring your codebase:

dev-scope analyze
dev-scope impact
๐Ÿ”ฎ Whatโ€™s Next

Iโ€™m planning to improve:

More language support
Better visualization
Performance optimizations
๐Ÿค Feedback

This is just the beginning.
If you try it, Iโ€™d love to hear your thoughts!
