💻 Deno 2.4: deno bundle is Back
Deno 2.4 reintroduces the deno bundle command for creating single-file bundles for both the server and client side, complete with support for npm and JSR dependencies and automatic tree-shaking. You can also now include arbitrary files into modules using import, and Deno’s built-in OpenTelemetry support is now stable. It’s a substantial release.
