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?

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 😉

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.

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

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?

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.

Collapse

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

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

Collapse

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"

Great article! Any suggestions for a good Deno webhost for small projects?

Aral Roca Author

You can use Vercel, that is free for personal projects. To add deno on Vercel you can follow this: github.com/lucacasonato/now-deno

does it compile the .ts file into .js one or does it directly run ts files?
