How to install multiple versions of same package in Npm

In this tutorial, we will learn how to install multiple versions of the same package in npm.

When we install a package using the npm install package-name command, it will download the current stable version of the package inside node_modules folder and add it to package.json file.

To install multiple versions of the same package, we need to use the package alias syntax which is supported from the npm v6.9.0.

Example:

npm install react15@npm:react@15

npm install react16@npm:react@16

This above command installs the react library v15, v16 by aliasing react15 and react16.

The package.json file looks like this.

  "dependencies": {
    "react15": "npm:react@^15.6.2",
    "react16": "npm:react@^16.13.1"
  }

Uninstalling multiple versions

To uninstall the multiple versions, we need to use the npm uninstall command followed by the alias name.

npm uninstall react15npm:react@15

npm uninstall react16npm:react@16
