![]() ![]() It also supports some Node.js libraries with npm compatibility. Similar to Deno, it ships single binaries and has Web API support built in. Jarred Sumner regularly provides updates on the development of Bun along with recent benchmarks on Twitter so be sure to follow him to keep up to date with it all.īun also includes bundling and task-running features for JavaScript- and TypeScript-based projects. This resulted in Bun handling about 68,000 requests per second compared to about 29,000 and 14,000 for Deno and Node.js, respectively. Regarding its performance, the Bun maintainers provide an example benchmark running an HTTP handler that renders a server-side page with React. ![]() This makes it a very attractive proposition if it can deliver on all of that. ![]() One of its biggest draws is its performance which is demonstrably faster than both Node.js and Deno. Powered by Zig, its aim is to be an all-in-one runtime and toolkit with a focus on speed, bundling, testing, and compatibility with Node.js packages. Bunīun is the latest runtime competing for your attention. Fresh is a web framework built for Deno and Lume is their static site generator. To ease deployment, it ships applications as a single-contained executable.ĭeno also has a tooling ecosystem around it to enable developers to jumpstart their projects. It's also designed to better support JSX and TypeScript, as well as be more oriented toward web standards. In Deno, file, network, and environment access must be explicitly enabled so that security issues that typically arise from these areas are less likely. One of its main focuses is to improve Node.js security. You can see and hear more about Ryan’s motivation behind Deno in this recorded talk from JSConf EU. Like Node.js, it was created and launched by Ryan Dahl with the hopes of improving upon what is provided in Node.js. Denoĭeno is a Rust-based JavaScript runtime. This is where Deno and Bun come in to add options in the JavaScript runtime landscape. But as with any runtime or technology, there is always room for improvement. Today there is a vast ecosystem centered on Node.js, with resources and libraries galore. With it, developers can create advanced backend-driven applications using JavaScript. It's fair to say it revolutionized what you could do with JavaScript when it entered the market. It was created by Ryan Dahl and launched in 2009. Node.js is the reigning champion of JavaScript runtimes and was ranked the #1 most popular web technology in 2023 by Stack Overflow developers. Introducing the JavaScript runtimesīefore you compare these runtimes based on their performance, stability, and security, let's give a basic overview of each: Node.js Knowing what each runtime offers can help you make the most educated decision. Do you prefer stability or speed? Do you want native TypeScript support with a richer runtime or a more customizable environment? These are just a few examples of questions you might ask yourself when deciding on a runtime. Your team's preferences, such as the experience they have with the runtimes and their willingness to experiment, will all factor into which runtime is right for you. It also affects the ease of development and scalability.īeyond the different features available and how they impact performance, developer experience is important as well. The runtime you choose will have a significant impact on the performance of your applications, with request handling and database access speeds varying considerably. Or you can choose to use JavaScript runtimes for general-purpose scripting. This means you can deliver sites as hosted applications. JavaScript runtimes let you run application code outside the browser. Book a live demo Why choosing the right JavaScript runtime matters ![]()
