Apache MINA an abstract event-driven asynchronous API over various transports such as TCP/IP and UDP/IP via Java NIO Netty a non-blocking I/O client-server framework for the development of Java network applications similar in spirit to Node.js
JavaScript Broadvision Server-side JavaScript AS. One of the early entrants in the market during the eCommerce dot-com bubble, they have vertical solution packages catering to the eCommerce industry. Bun implements Apple's JavaScriptCore engine as a standalone (outside the browser) asynchronous Javascript interpreter. An open-source project with its own npm-compatible package manager, and many built APIs, tooling and utilities. Node.js implements Google's V8 engine as a standalone (outside the browser) asynchronous Javascript interpreter. A vigorous open-source developer community on GitHub has implemented many supporting products, notably npm for package management and Connect and Express app server layers. Deno community developed Rust project, spearheaded by Ryan Dahl who also created Node.js, it directly targets TypeScript but also supports JavaScript and WebAssembly via V8; employs asynchronous, event-based I/O model via promise-based APIs and Tokio scheduler, uses an API security model via FlatBuffers and implements package management via ES2015 modules.
