Install repositories from GitHub to node_modules for Deno

README.md

Deno doesn't have a way to install repositories from GitHub to the local node_modules folder.

deno_install.js

// Creates node_modules folder in pwd
// import "npm:esbuild";
// import ...

const decoder = new TextDecoder();
// Download GitHub repository to node_modules/.deno, link in node_modules
async function installRepositoryFromGitHubToNodeModules(url) {
  return new Deno.Command("/bin/bash", {
  /*
    cd node_modules/.deno
    git clone "$1"
    cd ..
    ln -s  "`pwd`/.deno/$2" "`pwd`"
  */
    args: [
      "install_from_github.sh",
      url,
      url.split("/").pop(),
    ],
  }).output();
}

const { code, stdout, stderr } = await installRepositoryFromGitHubToNodeModules(
  "https://github.com/guest271314/wbn-sign-webcrypto",
);

console.log([stdout, stderr].map((result) => decoder.decode(result)));

install_from_github.sh

cd node_modules/.deno # Assumes node_modules folder exists in pwd
git clone "$1"
cd ..
ln -s  "`pwd`/.deno/$2" "`pwd`"

I did not follow how Deno does that for import "npm:..." completely. I omitted creating a nested node_modules folder in node_modules/.deno/<module_name>/node_modules/<actual_module>. The code just creates node_modules/.deno/<actual_module> and links to that.
