res.sendFile absolute path

Just try this instead:

res.sendFile('public/index1.html' , { root : __dirname});

This worked for me. the root:__dirname will take the address where server.js is in the above example and then to get to the index1.html ( in this case) the returned path is to get to the directory where public folder is.

The express.static middleware is separate from res.sendFile, so initializing it with an absolute path to your public directory won't do anything to res.sendFile. You need to use an absolute path directly with res.sendFile. There are two simple ways to do it:

1. res.sendFile(path.join(__dirname, '../public', 'index1.html'));
2. res.sendFile('index1.html', { root: path.join(__dirname, '../public') });

Note: __dirname returns the directory that the currently executing script is in. In your case, it looks like server.js is in app/. So, to get to public, you'll need back out one level first: ../public/index1.html.

Note: path is a built-in module that needs to be required for the above code to work: var path = require('path');
