Hey are the docs missing a build step for deno?

Hey thanks for submitting the issue! The bug is in the documentation (which I will fix). Try running:
deno run --allow-run --allow-read --allow-env src/example/autorun.ts

This command runs the server and uses ESBuild to build (continuously) the client code.

LMK if this works for you. Sorry about that.

Hey just tried this new command, other issues arrose:

needed to run npm install in the deno folder, maybe switch to npm: prefix?

I'll add the fact that you need to run npm install before running the deno examples. Thanks!

running deno run --allow-run --allow-read --allow-env src/example/autorun.ts gives the following error

⚠️  ┌ Deno requests net access to "registry.npmjs.org".
   ├ Requested by `fetch()` API
   ├ Run again with --allow-net to bypass this prompt.
   └ Allow? [y/n] (y = yes, allow; n = no, deny) > Watcher Process started.
LiveViewJS (Deno) is listening at: http://localhost:9001

while the counter is still not working.

After adding the required additional permision the command becomes deno run --allow-run --allow-read --allow-env --allow-net src/example/autorun.ts returns the next error

Watcher Process started.
LiveViewJS (Deno) is listening at: http://localhost:9001
⚠️  ┌ Deno requests write access to "/home/<user>/.cache/esbuild/bin".
   ├ Requested by `Deno.mkdir()` API
   ├ Run again with --allow-write to bypass this prompt.
   └ Allow? [y/n] (y = yes, allow; n = no, deny)

In the end, the full command that worked for me without errors in the cli and examples functioning as expected was deno run --allow-run --allow-read --allow-write --allow-net --allow-env src/example/autorun.ts.

Thanks for sending this. I will update the README.
