Answer 1

Please Change
output: {
path:'./',
filename: 'index.js',
}
To
output: {
path: __dirname+'/',
filename: 'index.js',
}
Or in other words change path: __dirname + '/'

Answer 2

If you're using ES modules, use this:
output: {
path: process.cwd(),
filename: 'index.js',
}
or
output: {
path: path.join(process.cwd(), 'dist'),
filename: 'index.js',
}
