Overview
Dependency Management defines the deterministic dependency resolution strategy using pnpm lockfiles to ensure reproducible builds across all environments.
Description
The Dependency Management principle establishes the practices and tooling for managing third-party dependencies in the Dify frontend. At its center is the pnpm lockfile, which records the exact resolved version of every direct and transitive dependency, along with their integrity hashes. This lockfile guarantees that every developer, CI runner, and production build installs identical dependency trees, eliminating the "works on my machine" class of bugs caused by version drift.
The principle mandates that the lockfile be committed to version control and treated as a first-class artifact of the dependency update process. Dependency additions and upgrades follow a deliberate workflow: the developer updates the package manifest, runs the install command to regenerate the lockfile, verifies that tests pass with the new dependencies, and commits both the manifest change and lockfile update together. This workflow ensures that dependency changes are reviewed and tested just like code changes.
Beyond the lockfile itself, the principle covers pnpm's workspace protocol for managing inter-package dependencies within the monorepo, hoisting policies that control which dependencies are accessible to each package, and peer dependency resolution strategies. These configurations work together to maintain a clean dependency graph where each package explicitly declares its requirements and does not accidentally rely on dependencies hoisted from sibling packages.
Usage
Use this principle when:
- Adding, upgrading, or removing frontend dependencies via pnpm
- Configuring workspace dependency relationships between packages in the monorepo
- Debugging dependency resolution issues or conflicting package versions
Theoretical Basis
Dependency Management follows the Reproducible Builds principle from software supply chain security, where build outputs are deterministic given the same inputs. The lockfile mechanism implements the Snapshot pattern, capturing the complete dependency state at a point in time. Pnpm's content-addressable storage and strict node_modules structure draw from the Nix package manager's approach to isolated, reproducible dependency management.
