Docs on deno cache

Hi all, I’m confused about the state of the deno cache subcommand. It seems that the online docs are redirecting to deno install now, but $ deno help cache still gives info in v2.0.6. Is deno cache going away, to be replaced by deno install?

Serve a directory index with oak?

Hi, I’m wondering if anyone can help me out having Oak serve a directory index (the way apache does, for instance) if a user goes to /some/directory/path? (Sorry if this is the wrong discord, I couldn’t find one related to Oak…)

Does Safari on OSX support CSS nesting?

It seems to pass all the tests at https://codepen.io/bramus/pen/oNdrypM But everything is yellow in this test:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Does your browser support CSS Nesting?</title>
  <link rel="icon" type="image/png" href="#">
</head>
<body>
<h1>Does your browser support CSS Nesting?</h1>
<div>
  this should be yellow
  <p>this should be light blue</p>
</div>
<style>
div {
  background: lemonchiffon;
  p {
    background: lightblue;
  }
}
</style>
</body>
</html>

Is there a way to test for css nesting support?

I’ve run into some trouble with nesting support on mobile browsers, and I was thinking it might make sense to make a non-nested version until browser support is wider. I would like to do something like:

@supports (nesting){
  .nested {
    .selector {
      color:red;
    }
  }
}

@supports (nesting){
  .nested {
    .selector {
      color:red;
    }
  }
}

Obviously nesting won’t work there, is there some way to do the equivalent?

Is this how @apply works in tailwind?

I'm not a tailwind person but I recall seeing somewhere that there it has something called @apply, which might be something I have been wishing were possible in css for a long time. Namely, I would like to be able to say:

.primary-heading {
  color:maroon;
  font-family: sans;
  text-shadow: 1px -1px 1px black;
}

.some-heading {
  @apply(.primary-heading);
}

.primary-heading {
  color:maroon;
  font-family: sans;
  text-shadow: 1px -1px 1px black;
}

.some-heading {
  @apply(.primary-heading);
}

Another way to think about this is that i would like to be able to put multiple properties in a css variable, but of course that’s not possible. Does @apply work that way in tailwind?

Is CSS nesting ready for production?

caniuse.com says it is supported across all major browsers, is that enough to start using it in production? https://caniuse.com/css-nesting

Deno KV: Should I expect 'value too large' errors inserting a JSON file with kv.set?

I was trying out kv and quickly ran into something I found surprising;

let kv = await Deno.openKv('omg.db')

let hieroglyphsJSON = await Deno.readTextFile('./hieroglyphs.json')
let hieroglyphs = JSON.parse(hieroglyphsJSON)

kv.set(["hieroglyphs"], hieroglyphs)

let kv = await Deno.openKv('omg.db')

let hieroglyphsJSON = await Deno.readTextFile('./hieroglyphs.json')
let hieroglyphs = JSON.parse(hieroglyphsJSON)

kv.set(["hieroglyphs"], hieroglyphs)

hieroglyphs.json is not huge (360K), and yet I get this error:

$ deno run --unstable --allow-write --allow-read kv.js
error: Uncaught (in promise) TypeError: value too large (max 65536 bytes)
kv.set(["hieroglyphs"], hieroglyphs)
   ^
    at Kv.set (ext:deno_kv/01_db.ts:87:41)
    at file:///Users/me/kv.js:8:4
    at eventLoopTick (ext:core/01_core.js:183:11)

$ deno run --unstable --allow-write --allow-read kv.js
error: Uncaught (in promise) TypeError: value too large (max 65536 bytes)
kv.set(["hieroglyphs"], hieroglyphs)
   ^
    at Kv.set (ext:deno_kv/01_db.ts:87:41)
    at file:///Users/me/kv.js:8:4
    at eventLoopTick (ext:core/01_core.js:183:11)

I feel like I’m missing something obvious; am I trying to do something kv wasn’t designed for? TIA

Checking for circular module dependencies?

Hi, I’m wondering if there is some way to detect whether there are circular dependencies in a set of modules. Ideally, it might look something like this:

let detectCircularDependencies = fileNames => { … } 

// then i'd call

detectCircularDependencies('./a.js', './b.js', './c.js')
Circular dependency found: a.js > b.js > c.js > a.js

let detectCircularDependencies = fileNames => { … } 

// then i'd call

detectCircularDependencies('./a.js', './b.js', './c.js')
Circular dependency found: a.js > b.js > c.js > a.js

Or something like that.

Is inspecting import.meta.url a reliable way to distinguish browser and deno contexts?

I have been trying to figure out a good pattern to import JSON that will work whether called in deno or the browser. This is what I was thinking:

let data

if(import.meta.url.startsWith('file')){ // we’re in deno
  let jsonstring = await Deno.readTextFile('delete.json')
  data = JSON.parse(jsonstring)  
} else if(import.meta.url.startsWith('http')){ // we’re in the browser
  let response = await fetch('delete.json')
  data = await response.json()
}

export {data}

let data

if(import.meta.url.startsWith('file')){ // we’re in deno
  let jsonstring = await Deno.readTextFile('delete.json')
  data = JSON.parse(jsonstring)  
} else if(import.meta.url.startsWith('http')){ // we’re in the browser
  let response = await fetch('delete.json')
  data = await response.json()
}

export {data}

I would welcome advice as to whether this is a good approach to this problem. thanks 🙏
