![]() Here’s how to use it with Rails (our main backend engine) and with Ember-CLI (our default SPA framework). Of course, you can also write your own package if you want :) Sources are open, so feel free to contribute. LiveReload has a great support from developers and it works for almost every setup and framework including Rails, Ember, Angular, and React.It could even work as a standalone server. Based on type of the change, the page is reloaded (when editing template markup) or the code is live-injected into our app (it currently supports images and stylesheets - including preprocessors). The server monitors our project files and when it detects any changes, it automatically notifies our client (browser). Without going too deep into specifics - the basic concept is that we inject a little JS snippet into our page, which communicates with the LiveReload server. To put it simply, LiveReload’s main function is to act as an automatic “refresh” button. And guess what… It works! You probably want to know how, right? What’s it all about? LiveReload is an app introduced in 2012 by Andrey Tarantsov, in an attempt to make our lives easier and less frustrating. Have you ever been frustrated by needing to click “refresh” when working with your code? Or maybe compiling assets takes too long so that you have to wait a couple of seconds to see the result of a small change? If you answered yes to either of these questions - I’m sure that this tutorial is for you. ![]() Do you want to keep up on the latest Node.js and Open Source news and developments?

If you answered yes to either of these questions - I’m sure that this tutorial is for you.Perhaps it will be introduced again in a future patch. It seems to have been supported in the past, but was removed a few months ago. Although pm2 is a great tool, it no longer seems to support monitoring for file changes. Update: Many of you suggested that pm2 should also be included in this list. I was hooked after using it once: it’s fast, simple to use, and is greatly supported by the community. I recommend trying out nodemon first and checking out the others if you are not satisfied with it’s performance. Not only are they the most actively developed amongst the alternatives, the support from the users is overwhelming as seen by the number of GitHub stars (as of December 9, 2013):įor those of you in a production environment and are already using forever to keep your processes alive, you can simply add the -w flag on your startup script instead of having to install another dependency.įor a development environment, using nodemon, supervisor, or node-dev are all great solutions to having to manually restart the server after every code change. By default, the image will store in current directory.The replacement text (in casethe image cant be found) will be the text you wrote. I was most impressed with forever and nodemon after researching and trying out all of the various alternatives. By using this flag, we not are only automatically restarting the application when the code changes, but also when and if the application goes down. Hopefully we’ll be able to use import() before too long. Be specific.) 0.6.2 Why is this important document.write is getting out of favor. In this case, it gives you the option of restarting the server on file changes by using the -w flag. What version are you using (Don't say latest. With all that time you’re saving, you can unglue yourself from your seat and go out for a walk or take an extra coffee break.įorever is not only a great CLI tool for keeping your app running continuously in a production environment, but also has advanced features that support running multiple node processes as background services. These seconds can really add up if you are constantly making a lot of little changes to your code. Luckily there are many tools available that can automate this process for you, saving you valuable time and unnecessary pain. As a newbie Node.js developer coming from a Java and PHP background, I found the process of having to search for the correct node terminal and hittingĪfter every code change to be very archaic.
