Attempts to transform arbitrary ctx.project into a valid Node.js project:

1. Changes import specifiers to be Node-friendly:

   • changes extension in relative specifiers to .js,
   • replaces some https:// imports with bare specifiers.

2. Changes *.deno.js imports specifiers to *.node.js (import './deps.deno.ts' -> import './deps.node.js'). This can be used for re-exporting dependencies and other runtime-specific code.

3. Rewrites remaining https: imports to point into vendorDir, if specified:

   // @filename: tsconfig.json
   {
     "deno2node": {
       "vendorDir": "src/.deno2node/vendor/"
     }
   }
   

4. Imports Node.js shims for Deno globals from shim file, if specified:

   // @filename: tsconfig.json
   {
     "deno2node": {
       "shim": "src/shim.node.ts"
     }
   }
