Update Package Version in Package.json

As a developer, you might have seen some warning of deprecation over the terminal when you use old versions of packages. This situation mainly occurs when you work on a long time project and updating an existing project. Since in an application, there is a need of so many packages and its very difficult to update each package one by one.

For the first time, When I came to such a situation I was a beginner and I do the task manually. But next time when I got time to search this over google I found a very easy way to update all the code at once.

In this article, I am going to explain the way in which is most easy to update the package in our application.

Using npm-update-check package

It works same as npm update command. This package is available at npmjs.org.The difference is that it's a utility that automatically adjusts packages which are listed into package.json file , whenever any updates are required. For that we need to install it via command: 

After installing the above package to a global location, now we will be able to update packages automatically. The next step is to update all the packages by running the command:

Finally,  install it via npm install.
