Can basic-auth middleware support Fastly Compute@Edge?

[metrue]

Compute@Edge does not have built-in crypto, currently the basis-auth middleware is using crypto.subtle.digest to build the timingSafeEqual to do the constant time comparison, as you said, polyfill the digest with digest.hash_sha256 should work.

Another thing we may need to take care of it is the Buffer which is not ready in WASM either but we use it in https://github.com/yusukebe/hono/blob/master/src/middleware/basic-auth/basic-auth.ts#L36, the document gives an example polyfill with webpack, but I think it's not what we need because hono should not depend on user's webpack configure.

module.exports = { // ...
  // Shimming globals
  plugins: [
    new webpack.ProvidePlugin({
        // Polyfill the URL standard
        URL: "core-js/web/url",
        // Polyfill Node.js' buffer (requires https://www.npmjs.com/package/buffer)
        Buffer: ["buffer", "Buffer"],
    }),
  ],

Fixed on #86 using polyfill.
