node-to-bun

Migrate Node.js projects to Bun by analyzing dependencies, configurations, and test pipelines for compatibility. The process updates package.json scripts, tsconfig, and lockfiles while identifying native module incompatibilities to ensure builds and tests run under Bun 1.0+.

Incompatible Node.js dependencies are typically native or problematic modules. Dependency compatibility analysis reads package.json to identify these modules and maps them to recommended Bun-compatible alternatives to prevent migration failures.

Yes, you can migrate monorepos using npm, yarn, or pnpm workspaces to Bun. The migration handles workspace configurations, processes lockfile conversions, and provides specific workspace guidance to ensure single-package and monorepo structures function correctly.

Update package.json and tsconfig for Bun compatibility by adjusting build scripts, engines, and test tooling configurations. The migration process recommends specific updates to ensure these files align with Bun 1.0+ runtime requirements and execution environments.

Limitations when migrating Node.js CI pipelines to Bun include native module incompatibilities that require replacement dependencies. The migration provides CI examples, verification steps, and rollback procedures to manage these constraints and ensure continuous integration stability.

A migration report is generated to summarize required configuration changes, incompatible dependencies, and verification steps. This BUN_MIGRATION_REPORT.md document outlines the necessary actions to safely convert your Node.js project to the Bun runtime.
