Dependencies
External code your project relies on to function.
why it matters
Your site depends on Next.js. Your tracker depends on Pillow. If dependencies aren't installed, nothing runs. If they're outdated, things break. Dependency management is invisible until it isn't.
how you use it
npm install installs all dependencies listed in package.json. pip install Pillow installs Python dependencies. Dependencies are tracked in lock files. Don't edit those manually.
