How to workaround `deno compile` binary file limitations?

In my app I'm using sharp and after compile it looses the ability to load dll.

❯ ./server
error: Uncaught (in promise) Error: Could not load the "sharp" module using the darwin-arm64 runtime
undefined: dlopen(/var/folders/4f/6rr3fjvx2wq742xvnz3lf1740000gn/T/deno-compile-server/Chat/node_modules/.deno/@img+sharp-darwin-arm64@0.33.0/node_modules/@img/sharp-darwin-arm64/lib/sharp-darwin-arm64.node, 0x0001): tried: '/var/folders/4f/6rr3fjvx2wq742xvnz3lf17)
Possible solutions:
- Add platform-specific dependencies:
    npm install --os=darwin --cpu=arm64 sharp
  or
    npm install --force @img/sharp-darwin-arm64
- Consult the installation documentation: https://sharp.pixelplumbing.com/install

Is there any way to workaround this problem?

DLLs are not supported in deno compile right now. Sadly there's no workaround atm

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
