Socket.io server - require.resolve()

[a-lucas]

I have been going trough all issues so far, and googling a bit.

In Socket.io source code, they use require.resolve, which is not supported by browserify.

So I excluded 'socket.io' from nexe.browserify.excludes in the package.json file.

I tried to create a node_modules folder inside the generated bin folder, with no luck. "Can;t find native module" it says. The problem is that socket.io is not a native module anymore, just plain JS files.

Is there a way to include unsupported files alongside the generated bin? is the solution to list every single file required by socket.io inside the requiredFiles array ?

I will now try to replace require.resolve by something else and see if that fixes it. I'll keep you updated with this.

I fixed it by hacking socket.io source code :

Edit the file socket.io/lib/index.js

At the top:

var exists = require('fs).existsSync;

Then replace the problematic code with :

  if (v && !clientSource) {

    var clientSourcePath = path.resolve(__dirname, './../../socket.io-client/dist/socket.io.min.js');
    var clientSourceMapPath = path.resolve(__dirname, './../../socket.io-client/dist/socket.io.min.js.map');
    if(!exists(clientSourcePath)) {
      throw new Error('Cannot load socket.io.min.js');
    }
    if(!exists(clientSourceMapPath)) {
      debug('could not load sourcemap file');
    } else {
      clientSourceMap = read(clientSourceMapPath);
    }
    clientSource = read(clientSourcePath);


/*
    clientSource = read(require.resolve('socket.io-client/dist/socket.io.min.js'), 'utf-8');
    try {
      clientSourceMap = read(require.resolve('socket.io-client/dist/socket.io.js.map'), 'utf-8');
    } catch(err) {
      debug('could not load sourcemap file');
    }
*/
  }

Closing as I just submitted a PR to socket.io project.

I'm using nexe 2.0.0-rc.22 and socket.io 2.0.4 and I still get the require.resolve error with the default setting (giving only an index.js entry point).

What exactly should I config to get this to work?

Huh, weird. The call to require.resolve (in socket.io code) is completely unnecessary
