How to audit legacy code in 5 minutes

The Legacy Project Nightmare

We all know this situation. A client calls you to take over an existing project. "It's just a few changes," they say. You open the repo: 1500 files, zero documentation, and the last commit was in 2019.

The Traditional Approach

Usually, you would spend your first 3 days:

1. Reading package.json to guess the stack.
2. Trying to start the project (and failing due to a missing env variable).
3. Drawing illegible diagrams on a napkin.

The ReposLens Approach

There is a better way. Here is how to do a professional audit in 5 minutes:

1. Import the Repo

Simply paste the GitHub URL into ReposLens. No need to install the project locally.

2. Zoom Out (Helicopter View)

Look at the global map. Immediately identify the "big blocks": Where is the database? What are the main modules? Are there external services (Stripe, AWS, Firebase)?

3. Isolate Flows

Click on a critical module (e.g., UserModule). ReposLens will highlight everything connected to it. You will see immediately if this module has circular dependencies or is too coupled (Spaghetti Code).

4. Export the Report

Generate a share link or an architecture image. Pair it with our legacy code audit checklist and send it to the client with your recommendations.

Result: You look like an ultra-efficient expert, and you price your quote with precision.

Don't fear Legacy anymore. Visualize your codebase and take control.
