How can I do simple image recognition with Deno?

I think this task is less simple than you might think. BTW hugging face does more than just LLMs

Deno import use for local files?

I use deno as a replacement to bash (checkout dax, it is fantastic for that) I'm confused, why did dynamic imports not work for you? That seems like way way less work than creating a server

Is deno's cache philosophy coherent for local files ?

You might want to add something like this at the top:

const load = (path)=>import(
    path+(
        Deno.env.get("PROD") ? "" : `${Math.random()}`
    )
  )

const load = (path)=>import(
    path+(
        Deno.env.get("PROD") ? "" : `${Math.random()}`
    )
  )

Then use that instead of imports:

// var is the only one that let's the cell run twice without error
var utils = load("./utils.ts")

// var is the only one that let's the cell run twice without error
var utils = load("./utils.ts")

Ah, for TS that is true, that's my bad for assuming the local import was JavaScript. Should still 100% be a bug across restarts though. I agree its annoying in Jupyter. To be fair though, python reimports also don't work in Jupyter. I mean python has some force-reload stuff but its about the same amount of work as force reloading in deno, and is equally not-good-for-prod.

It definitely shoudnt persist across restarts though. That would 100% be a bug for local-file-path imports. The "cache" is only in ram.

(I'm not part of the deno team btw) AFAIK NodeJS does this as well when ES imports are enabled. Its not a deno behavior, its an ES import vs common js behavior. It is annoying in the repl and juypter. Another painful edgecase (for files not repl) is execution order:

console.log("1")
import "hello_world.js"

console.log("1")
import "hello_world.js"

Will print "Hello world" then "1" Because static imports get hoisted to the top

How to workaround `deno compile` binary file limitations?

Well theres one hacky workaround. I made a tool last year https://deno.land/x/binaryify that lets us ES import .dylib files as a Uint8Array. We can then write that array to a temp file at runtime and then dlopen that file. It would look like: 1. Install binaryify 2. Run binaryify -- ./your.dylib 3. Instead of calling .dlopen do

import dylibBytes from "./your.dylib.binaryified.js"

let tempFile = await Deno.makeTempFile()
await Deno.writeFile(tempFile, dylibBytes)

Deno.dlopen(file)

import dylibBytes from "./your.dylib.binaryified.js"

let tempFile = await Deno.makeTempFile()
await Deno.writeFile(tempFile, dylibBytes)

Deno.dlopen(file)

Binaryify (as of today) will auto-update the "./your.dylib.binaryified.js" file every time time the "./your.dylib" file changes

JXS/TSX Transformation from within browser code?

I'm decently-highly confident the answer is no, not without some hacks like writing to a file or calling a child process. Theres also a decent number of ways to create a security vulnerability on the backend with user generated code. So I think babel in the frontend is your best bet
