[ERROR] File name too long

[TomokiMiyauci]

When attempting to build a package with many dependencies, the following error occurs:

error: Uncaught (in promise) Error: Build failed with 1 error:
error: File name too long (os error 63): mkdir ~
...

Reproduction:

import * as esbuild from "https://deno.land/x/[email protected]/mod.js";
import { denoPlugins } from "https://deno.land/x/[email protected]/mod.ts";

const result = await esbuild.build({
  plugins: [
    ...denoPlugins(),
  ],
  entryPoints: ["npm:[email protected]"],
  outfile: "./dist/bytes.esm.js",
  bundle: true,
  format: "esm",
});

console.log(result.outputFiles);

esbuild.stop();

This seems to be caused by the npmPackageId exceeding the OS limit.

How about using a hash value instead?

I also have an issue with long directories for ex (npm:@uiw/react-codemirror):

error: Uncaught (in promise) Error: Build failed with 1 error:
module/src/components/CodeEditor.tsx:2:23: ERROR: [plugin: deno-loader] File name too long (os error 63): mkdir '/Users/dov/Library/Caches/deno/deno_esbuild/@uiw/[email protected]_@[email protected]_@[email protected]_@[email protected]_@[email protected][email protected]__@[email protected]__@[email protected]__@[email protected][email protected][email protected][email protected]_@[email protected]/node_modules/@uiw'
  let error = new Error(text);
              ^

As a workaround, enabling nodeModulesDir option resolves this for me
