Answer 1

There are plenty of tools for this:

• nodemon
• supervisor
• node-hot-reload

And I'm sure you could find more.

Answer 2

I got the solution from this link.

I installed supervisor module as global installation

npm install supervisor -g

I stated my app like this

supervisor -e html,js  app.js

Here i am specifying to watch the changes in files with extensions .html and .js. So when these files are changed its automatically reloaded when the next request comes.No restart required.

You can simply disable swig's caching:

if (process.env.NODE_ENV !== 'production') {
  swig.setDefaults({ cache: false });
}
