Movimiento 0deps: Local Dependencies and Immutable Contracts

Software developers often install hundreds of external libraries. Modern frameworks rely on thousands of transitive dependencies. This means your app runs code from strangers you do not know.

This speed comes with a cost. You face software supply chain risks.

Every dependency increases your attack surface. Dependencies can:

  • Introduce security flaws.
  • Become targets for supply chain attacks.
  • Get abandoned by authors.
  • Change their public API.
  • Break backward compatibility.

The 0deps movement changes this. It asks: what if your app only relies on the code you control?

In a 0deps model, you bring all necessary code directly into your project repository. You do not download packages during installation or build time. Everything you need is there when you clone the repo.

This provides several benefits:

  • Reproducible builds.
  • No reliance on external package registries.
  • Centralized security audits.
  • Higher predictability.
  • Lower supply chain risk.

The goal is not to stop code from changing. Algorithms and security fixes must evolve. What stays the same is the public contract.

You design a stable interface for each library. For example:

  • authenticate()
  • createSession()
  • verifyPasskey()

The implementation behind these functions can change entirely. You can rewrite the logic or replace the library. The rest of your app never knows the difference.

This solves the biggest headache during updates. Usually, you worry about fixing a bug and breaking your app at the same time. With 0deps, the public API stays identical. Your application keeps working without code changes.

You isolate external tools behind internal adapters. If a library dies tomorrow, you only update the adapter. The rest of your system stays safe.

0deps does not hate open source. It wants to use open source more safely. Instead of dynamic installs, you treat libraries as integrated components. You audit them. You version them. You encapsulate them.

Software lives for decades. Libraries and frameworks die. 0deps ensures your application keeps running through all those changes.
