Node.js has been the king for a long time, but Deno and Bun are promising faster performance and better security. For a developer looking to stay relevant, which runtime should I invest my time in, and are companies actually hiring for these roles yet?

Node.js is still the safest bet for employment because of its massive ecosystem (NPM) and corporate backing. However, Bun is currently creating a lot of buzz due to its incredible speed as a bundler and test runner. Deno is excellent if you prioritize security and out-of-the-box TypeScript support. While "Bun Developer" isn't a common job title yet, knowing these tools makes you a more versatile engineer. Most enterprise companies are sticking with Node.js for now, but they are starting to use Bun for internal tooling and CI/CD pipelines to save time.
Is performance the only reason you are looking at Bun, or are you also frustrated with the complexity of the Node.js configuration files?
I think learning the fundamentals of Node.js is still essential, but keep an eye on Bun for personal projects to stay ahead of the curve.
I agree with Nancy. Node.js is the foundation, but Bun is showing us the future of how fast our dev environment could actually be.
Charles, Bun’s appeal is definitely the "all-in-one" nature. Not having to configure Vitest, Prettier, or a separate bundler is a huge productivity win. It removes the "configuration fatigue" that often comes with setting up a new Node.js project.
