===How to run/work with production mode for NodeJS Apps===

**Important - Before running your app in production mode, kindly test your app in development mode first. Only after extensive testing, you may then use the production mode.**

**Step 1 :** Log into N99panel. From under N99panel dashboard, click 'Node Apps'

\\

**Step 2 :** Now click 'Link a Node App

\\

**Step 3 :** Fill in the form as under

{{:nodejs:dev-form-prod.png?direct&400|}}

**Important points :**\\
  - Select the User/VHost (website)\\ 
  - Enter the ‘App Web path’ . This would be like /app1 or /app2 or it can even be the website root i.e. /\\
  - Enter the ‘App Port’ . The port entered under should be within the range of 40000 to 50000\\
  - Select the ‘App Mode’. This should be ‘Production’ variant - here in this example we have choose 'Production (node)' i.e. the app is fired with node command \\
  - Under the production filesystem path, enter the folder containing the app w.r.t. /home/{username}/node_apps/ . So in our case it is app1
  - Also finally select the Nodejs version that you wish to use with the App

In production mode the Node app runs w.r.t. system path reference. **To put it simply you need to ensure that any file references in your code, are absolute and not relative.** Lets say your Node app start point is /home/user1/node_apps/app1/server.js , and your server.js refers to contents.json , you would need to change it to /home/user1/node_apps/app1/contents.json .  

With the above steps, you have mapped the web-server's VHost/Website’s URL part to the to the specified port of the App, which will be launched by our environment from the specified source folder

**If your App is not working as expected, please visit the following article in order to debug it in production mode : [[:nodejs:production-mode-debug|How to debug NodeJS apps in production mode]]**\\

To manage the App process, you can do the same from within Node Apps -> App : Manage App State
