Why deno.exec is much larger than bun.exec

Does it minify the bytecode of only the code that I'm bundling, so only the single console.log("Hello world") in my example?

Why deno.exec is much larger than bun.exec

And what difference do you think it would make in my example, where I built a hello world app? Because the code was a single console.log statement without any imports

Why deno.exec is much larger than bun.exec

Ok, to clarify, which part of this is deno not doing? "All imported files and packages are bundled into the executable, along with a copy of the Bun runtime." In my example, I believe that deno is bundling the imported files and packages into the executable. It also includes the runtime, because that's how it executes.

Yes it does, that's the goal. You can also see in my example, it bundled the hello world script.

Why deno.exec is much larger than bun.exec

Informal test, on Windows, I created a Hello World single-file executable with both Bun and Deno Deno's executable is way smaller, 70% the size of Bun's

Why deno.exec is much larger than bun.exec

How does a single-file executable compare for each? Since those don't include things like the LSP?

How do deno devs bundle .js for browser projects? (SPAs, chrome extensions, etc)

so I get all the benefits of a nice CLI: --watch, etc

Thanks, does that require writing my own .ts file to do building? I was hoping to run a CLI, an esbuild invocation in my justfile / makefile, or something like that.

Tools to shrink the output of deno compile?

I'm guessing the 80MB is already a compile-specific build of deno with all the CLI tooling stripped out, deno fmt, deno install, etc?

Tools to shrink the output of deno compile?

This blog says 1.41 shrank the binaries from ~116MB to ~58MB, but deno 2 .exes are ~80MB https://deno.com/blog/v1.41#smaller-deno-compile-binaries

JSR publish: source .ts or transpiled .js w/sourcemaps?

So: publish .ts to JSR, do not compile it

JSR publish: source .ts or transpiled .js w/sourcemaps?

Nevermind, figured it out by publishing a module to JSR, though it wasn't immediately clear from jsr docs: JSR accepts your source .ts, renders docs from it, and automatically generates .js and .d.ts
