Tip: Make sure you commit your package.json and package-lock.json files to your source code as they are critical in identifying and resolving dependencies for your installation using NPM install.
package-lock.json - This file complements package.json and consists of all the package lineage information, which helps reconstruct the installation the same way on every install.package.json - This file contains configuration information about all the package dependencies for your application.You have to create it! You can change the file name, but that would need some further configuration. index.js - This is the main file picked up by default when you run your Express web or mobile application.This is because Express itself is made using Node.js node_modules folder - The node_modules folder consists of all the Node.js files that are used to create Express.Step 3: Check the contents of the installation, especially the package.json fileĬheck the contents of the directory created as part of this installation and see if the npm install worked! If it did, you'd find the following contents: This feature is extremely useful for making sure that all the dependencies are taken care of by just having the right package.json file in the repository. npm install alone, by default, doesn't do that. Note: The -save options saves the Express.js package to the package.json file. You might require additional privileges to do that. To run the following command, the PATH variable needs to be correctly set to the installation path of Node.js and npm.īased on your company's security infrastructure, you might need to run a command-line utility as an admin. To test the installation, you would need access to the command-line utility or PowerShell. Next, we will test whether the installation was successful. After the installation finishes, you are required to restart your Windows machine.
The last step is to press the Install button and wait for the installation to complete. As you would want to install both Node.js and npm, you shouldn't worry about the custom installation option. Advanced users can choose the custom install option, where you have the option of selecting to selectively install the components that were shown to you on the first screen of the installer dialog box. For most users, especially first-time users, the standard install is recommended. The installation comes in two formats - standard and custom. Step 4: Choose from Standard or Custom Installation If you have a specific location for installation, you can change the location by providing the path. In most cases, the default location works fine. Once you go ahead with that, you will be prompted to select the destination of the installation.
Step 3: Accept the Software Licence Agreement and Choose Installation DestinationĪfter that, it will prompt you to agree to the software license agreement. With npm, you can access the wide range of libraries built around Node.js using a simple command, i.e., npm install. Notice that the installer, by default, installs Node.js and automatically installs the de facto package manager for Node.js, i.e., the node package manager. The versions will differ on your system based on the package version you have downloaded. It will start with an introduction that tells you what the installer will install on your Windows system. Once you download the installer package from the website, you can start the installation by double-clicking on the icon. The LTS (long-term support) version is recommended for most users. Head over to the official Node.js website or use the v website to download the latest version of Node.js. Install Node.js and NPM Step 1: Download the Installer
