Monorepo Navigator

Navigate, manage, and optimize monorepos at any scale. Covers Turborepo, Nx, pnpm workspaces, and Lerna/Changesets for cross-package impact analysis, selective builds on affected packages only, dependency graph visualization, remote caching configuration, migration from multi-repo to monorepo with preserved git history, and coordinated package publishing with automated changelogs.

Core Capabilities

• Impact analysis — determine which apps break when a shared package changes, trace dependency chains, visualize Mermaid graphs, and calculate blast radius.
• Selective execution — run tests/builds only for affected packages, filter by changed files since a git ref, and skip unchanged packages in CI.
• Build optimization — remote caching (Turborepo/Vercel, Nx Cloud), incremental builds with input/output config, dependency-aware parallel scheduling, and artifact sharing.
• Publishing — Changesets for coordinated versioning, automated per-package changelogs, pre-release channels, and workspace:* replacement during publish.

When to Use

• Multiple packages/apps share code (UI components, utils, types, API clients)
• Build times are slow because everything rebuilds on every change
• Migrating from multiple repos to a single monorepo
• Publishing npm packages with coordinated versioning
• Teams work across packages and need unified tooling
