Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:

  1. Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical.

  2. Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.

  3. Cohesive DX. Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.

Bun is designed as a drop-in replacement for Node.js. It natively implements hundreds of Node.js and Web APIs, including fs, path, Buffer and more.

The goal of Bun is to run most of the world's server-side JavaScript and provide tools to improve performance, reduce complexity, and multiply developer productivity.

Bun.sh features and specs

  • Speed
    Bun.sh is designed for performance and is optimized for running JavaScript and TypeScript quickly. This can lead to faster development cycles and more efficient runtime performance.
  • Built-in Tools
    Bun.sh comes with a built-in bundler, transpiler, and package manager. This reduces the need for additional tooling and simplifies the development setup.
  • TypeScript Support
    Bun.sh has native support for TypeScript, making it easier for developers who prefer strongly typed languages to work seamlessly without additional configuration.
  • Compatibility
    Bun aims to be compatible with existing npm packages, reducing friction in adopting it for existing projects.
  • Lower Resource Usage
    Bun is designed to use fewer resources compared to some traditional Node.js setups, which could lead to cost savings in a production environment.

Possible disadvantages of Bun.sh

  • Ecosystem Maturity
    Bun.sh is relatively new compared to established tools like Node.js and may lack the ecosystem maturity, comprehensive documentation, and community support available for more established platforms.
  • Adoption Risk
    Early adoption of new technology can be risky. As Bun.sh is still evolving, there might be breaking changes or unstable features in future releases.
  • Learning Curve
    Developers who are accustomed to traditional Node.js environments might face a learning curve when adjusting to Bun.sh’s different approach and built-in tools.
  • Debugging and Error Handling
    Given its relative youth, Bun.sh might not yet have the robust debugging tools and error handling practices that more mature ecosystems provide.
  • Platform-Specific Issues
    There may be platform-specific issues or limitations, especially in less common development environments, which might require workarounds or lead to inconsistent behavior.

.NET Core features and specs

  • Cross-Platform
    .NET Core is designed to be cross-platform, allowing developers to build and run applications on Windows, macOS, and Linux, which provides flexibility in deployment.
  • Performance
    .NET Core offers high performance and scalability, making it suitable for a wide range of applications, from microservices to large-scale cloud services.
  • Microservices Friendly
    .NET Core's modularity and lightweight nature make it a good fit for developing microservices and deploying them using containers.
  • Unified Development Experience
    .NET Core provides a consistent set of development tools across different platforms, which enhances productivity and allows developers to use familiar tools.
  • Open Source
    Being open-source, .NET Core encourages community contributions and transparency, providing developers with access to the source code and reducing vendor lock-in.
  • Side-by-Side Versioning
    .NET Core allows multiple versions to be installed and run on the same machine, ensuring applications can run with their compatible version without affecting others.

Possible disadvantages of .NET Core

  • Learning Curve
    Developers who are new to .NET Core might face a steep learning curve, especially if they are switching from the traditional .NET Framework.
  • Limited Library Support
    While improving, .NET Core may have limited support for some libraries or frameworks that are available in the full .NET Framework.
  • Evolving Platform
    As a relatively newer platform compared to the full .NET Framework, .NET Core is still evolving, which can lead to frequent changes and updates.
  • Compatibility Issues
    Porting existing applications from the .NET Framework to .NET Core may introduce compatibility issues that require additional refactoring.

  • Rove : Straight up PostgreSQL migration.
    Rove is a fast, no-fluff migration manager for PostgreSQL built with Bun and TypeScript. It’s built for devs who just want to write raw SQL, version it in folders, and run it with confidence. - Source: dev.to / 8 days ago
  • 🚀 Switching from Node + Express to Hono + Bun and I’m not looking back.
    Let’s talk real — Express had its moment. But the dev world? It's moving fast. I recently jumped into building APIs using Hono (tiny, fast, edge-native framework) with Bun (next-gen JS runtime), and honestly... The experience is smooth, fast, type-safe, and just way more modern. - Source: dev.to / 22 days ago
  • Deno's Decline
    Https://bunny.net/ - a CDN, it has nothing to do with https://bun.sh/ as far as I can tell. - Source: Hacker News / 23 days ago
  • Flash-install
    Inspired by the speed of Bun, the reliability of Yarn, and the efficiency of PNPM. - Source: dev.to / 29 days ago
  • The Case for IRIS and JavaScript
    An early incarnation of server-side JavaScript was created by Netscape around the same time, but it wan't particularly successful.  It wasn't really until Ryan Dahl created Node.js in about 2010 that server-side JavaScript really took off and became "a thing".  More recently a serious competitor to Node.js - Bun - has emerged: its main advantage over Node.js is its stellar performance. - Source: dev.to / about 1 month ago
