Function Dependency Warner

⚠️ Warns developers when they're editing a function that has known downstream dependencies—minimizing the risk of unintended code breakage.

✨ Features

🔍 Detects when a user edits a function that has known dependent functions.
⚠️ Shows a warning if the function you're modifying may impact others.
📂 Reads a custom JSON-based dependency map (dependencies.json).
🧠 Ideal for large codebases or collaborative projects where function dependencies are critical.

Or from VSIX:

code --install-extension function-dependency-warner-0.0.1.vsix

Add a path to your dependencies.json in VS Code settings:

"funcWarn.dependencyFile": "./dependencies.json"

Default is ./dependencies.json in the root of the workspace.

{
  "saveUser": ["sendEmail", "logActivity"],
  "sendEmail": ["trackEmail"],
  "processOrder": ["updateInventory", "sendInvoice"]
}

If you now edit saveUser, the extension will show:

⚠️ Changing 'saveUser' may affect: sendEmail, logActivity

To build from source:

npm install
npm run compile

To package:

vsce package

To install the .vsix manually:

code --install-extension function-dependency-warner-0.0.1.vsix

Now supports arrow functions, class methods, and static code analysis for function detection. Handles nested dependency structures.
