Bun vs snpm

Bun combines a JavaScript runtime, package manager, test runner, and bundler in one binary. It runs JavaScript and TypeScript on JavaScriptCore, with support for Node.js APIs and node_modules. Its npm-compatible package manager supports workspaces, catalogs, overrides, patches, readable lockfiles, private registry authentication, dependency resolution, and offline installation. The test runner includes Jest-compatible expectations, mocks, snapshots, DOM testing, and coverage. For builds, Bun handles TypeScript, JSX, CSS, and HTML for browsers and servers, and includes a development server with hot module reloading and single-file executables. Built-in APIs cover PostgreSQL, MySQL, SQLite, Redis, S3-compatible storage, HTTP, and WebSockets. The project names Next.js, Remix, Nuxt, Astro, SvelteKit, Hono, and Elysia among frameworks that run on Bun. It is MIT-licensed and developed publicly on GitHub. Bun runs on Linux, macOS, and Windows, subject to minimum OS versions and x64 processors with SSE4.2. Install options include an official script, npm, Homebrew, Windows package managers, and Docker. Support and discussion are available through Discord.

snpm is a free, open-source package manager for Node.js projects and JavaScript workspaces. It runs on Linux, macOS, and Windows, with native binaries for x64 and arm64. Its CLI provides npm-style install, add, run, exec, and dlx commands, plus auditing, dependency inspection, license listing, patching, packing, publishing, and store maintenance. Workspaces can be filtered by name, glob, path, dependency walk, or Git reference. snpm imports pnpm, Bun, Yarn, or npm lockfiles when snpm-lock.yaml is missing, then uses its own lockfile as the source of truth. Packages are downloaded once into a shared store and linked through a node_modules/.snpm virtual store. Lifecycle scripts are blocked unless allowed, package age can be restricted, and tarball authentication is registry-scoped. Publishing includes workspace fan-out, tags, OTP, and dry-run modes. An included Node manager handles version installation and discovery. The npm install script requires Node.js 18 or newer.
