For the problem “typeerror: path must be absolute or specify root to res.sendfile.” I tried to fix it, but It doesn’t work and returns the result I want. Here is my program:

var app = require('express')();
 var http = require('http').Server(app);
 
 app.get('/', function(req, res){
  res.sendFile('index.html');
 });
 
 http.listen(3000,function(){
  console.log('listening on : 3000');
 });

and

has occurred. I’ve checked the entire command line, but still can’t find the mistake.

    The cause:  Your index.html file not being in the root directory is most likely the cause.

    Additionally, if it is in the root directory, relative referencing can not work.

    Solution:

    You must set root in the config item for res.sendFile() and (or) enter an absolute path (rather than a relative one). Examples:

    // assuming index.html is in the same directory as this script res.sendFile(__dirname + '/index.html');

    Or provide a root (used as the initial argument to res.sendFile():

    res.sendFile('index.html', { root: __dirname });

  2. In.mjs files, we don’t yet have __dirname

    hence 

    res.sendFile('index.html', { root: '.' })
