Hi, great article! I was following this and wanted to add my own stylesheet. So I made an external stylesheet and tried to load it in the html, but now the browser gets stuck at the request to the stylesheet in browser, the request stays pending.

Is there anything different I need to do? I think I need to include it in Deno static assets somehow?

Aral Roca • May 13 '20 • Edited

This is because you are only serving the index.html file on the server. You also need to serve the file with your styles. Normally a better way is just to serve a public dir with all the statics / assets.

Wow man that's a really clear and complete guide to get started with Deno. Thank you very much !

Little typo for the tests part :

| To run all tests, we just need to execute deno test.
| ➜ deno deno test

I guess it's just deno test 😉

hehe thanks! This is because I worked in a folder named deno... hah! I'm going to change it! Thank you

In the article, you mentioned that v1.0.0 is being released on the 13th of March 2020. I assume this is a typo? 😝

Great article by the way! Deno looks promising.

Aral Roca • May 12 '20

It's May yes. It's a typo. I'm going to fix It! Thanks

Hammed Oyedele • May 12 '20

It is not a typo...the project has been going on for long and the wait for 1.0.0 is over.

Ali Ilman • May 12 '20 • Edited

The latest version in overall is 1.0.0-rc2, not 1.0.0. Both are different. 🙂

I know that, v1. 0.0 will be released on May 13th so what the author said is not a typo

Got this example working in Deno 1.0.0 with debugging and breakpoints in VSCode. But for some reason VSCode refuses to show console.log() outputs. Ideas to why?

Great article. First tutorial for deno I have seen.

Murtaza Ahmad • May 11 '20

what is main difference between nodejs and deno

Tremaine Buchanan • May 12 '20

Deno is an improvement on the mistakes made in Nodejs as mentioned by its creator.

Simon Massey • May 13 '20

Watch this video from the inventor of Node.js who is the inventor of Deno who describes the 10 biggest regrets he has about design mistakes he made in Node.js youtu.be/M3BM9TB-8yA

Pasquale Mangialavori • May 11 '20

Thanks for found time writing this.

Ami Amigo • May 12 '20

Awesome! Let's be among the first people to learn it when it's officially out!

How can you deploy deno like we did in nodejs by using something like forever or pm2?

I know we can use docker. I just want to know other ways.

Aral Roca • May 16 '20

You can use pm2 with deno, pm2 can run non-node stuff.

Patrice Gauthier • May 13 '20

That's very interesting.
Do you know how is the caching of libraries locally with this new approach?

Aral Roca • May 17 '20

Is centralised for all your projects in the same folder. If you run deno info you can see where is stored.

➜  deno info
DENO_DIR location: "/Users/aralroca/Library/Caches/deno"
Remote modules cache: "/Users/aralroca/Library/Caches/deno/deps"
TypeScript compiler cache: "/Users/aralroca/Library/Caches/deno/gen"
