Reflect html changes in browser without restarting the express app

Question

I have an express app. I am using swig as the template engine. Is it possible to reflect my HTML changes in the browser when I click refresh. I don't want to restart the server every time I need to do a HTML change?

Answer 1

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.

Answer 2

There are plenty of tools for this:

• nodemon
• supervisor
• node-hot-reload

And I'm sure you could find more.

Answer 3

You can simply disable swig's caching:

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