How to bundle my project

I have a mod.js file that I wrote with Deno and I want to bundle it and it depends on bunch of other file

I ran

esbuild mod.js --bundle --format=esm --outdir=dist

esbuild mod.js --bundle --format=esm --outdir=dist

esbuild mod.js --bundle --format=esm --outdir=dist

esbuild mod.js --bundle --format=esm --outdir=dist and I try to use that in the browser but it doesn't download the dependecies
