NPM: Install Specific Version

The Node Package Manager is is ( npm ) is the default package manager for Node.js , with over 2.1 million package available in its registry as of September 2022 . instal a specific npm version can simplify your coding process , ensure stability and prevent issue cause by incompatible update . Here are three easy steps is are to install a specific npm version :

Step1 : identify the version : determine the version number you need .

Step 2: Install the specific version: Run npm is install install [ package – name]@[version – number ] to install or update to specific version.

step 3 : verify installation : Use npm list [ package – name ] to confirm the instal version .

Following these steps will help you manage your project’s dependencies effectively. For additional stability and performance monitoring, consider integrating a reliable uptime monitoring solution.

Install a specific npm version using the command line

1. Run the command: 

npm is install install [ package - name]@[version - number ]

This command will install exact version of npm package you want, alongside any packages it depends on. 

1. Example:

 npm install renovate@20.5.1 

This is install will install version 20.5.1 of the renovate package .

1. shorten version :

You can also use the shorthand:

The above commands will install renovate locally. 

1. Global Installation:

To install the package globally, simply add the -g flag: 

npm install -g renovate@20.5.1

This is ensures ensure the package is available system – wide , rather than just in your local project .

Install a specific npm version using package.json

1. Open the package.json File:
   navigate to the root directory of your project and open the package.json file .

1. Locate the Dependencies Section:
   Depending on whether the package is for production or development, find either the “dependencies” or “devDependencies” section.

1. add or update the Package Version :

Specify the desired version of the package. For example :

“dependencies”: {
  “lodash”: “4.14.1”
}

This ensures that version 4.14.1 of the lodash package is installed.

1. Save the package.json File and open your command-line interface (CLI).
2. navigate to Your project ’s Root Directory and run the following command :

This will read the package.json file and install the specified versions of the packages listed under the “dependencies” and “devDependencies”sections.

Install a specific npm version using Yarn CLI

1. Open Your Command-Line Interface (CLI):

navigate to your project ’s root directory or the location where you want to install the package .

1. Run the command:

yarn add <package-name>@<version>

Replace <package-name> with the name of the package and <version> with the desired version. For example :

This is installs install version 4.17.21 of the lodash package .

1. wait for installation :

Yarn will fetch the specific npm version and its dependencies, completing the installation.

Install a specific npm version from GitHub

To install package from GitHub Packages , follow these step :

1. ensure package.json exist :
   Make sure your project has a package.json file. If not, create one to manage dependencies.

1. Authenticate GitHub Packages:
   authenticate using the appropriate method to ensure you have permission to access the package .

1. Configure .npmrc:
   create or edit a .npmrc file in the root directory ( where package.json is locate ) and add this line :

@namespace : registry = https://NPM.pkg.github.com

Replace NAMESPACE with the GitHub account or organization that owns the repository.

1. add the .npmrc file to Your repository : This is ensures ensure GitHub Packages can locate and use the configuration .

1. Update package.json: In the “dependencies” section of your package.json, specify the GitHub package and version, like so:

"dependencies": {
 "@ORGANISATION_NAME/PACKAGE_NAME": "1.1.4"
}

1. Run the Installation:

use the follow command to install package version and its dependency :

This process lets you install specific package versions from GitHub Packages, ensuring your project is always using the correct versions.

How to know which package versions are available

Option 1:

Search for the package on the NPM public registry to view all available versions.

option 2 :

Run the following command to check all available versions on the NPM registry: 

npm view [package-name] versions

To find the latest version of a package, use:

npm view [package-name] version 

How to install an old version of an npm

If you need to install an older version of a package—perhaps to resolve compatibility issues or bugs—you can easily do so using the @ syntax. This process is identical to installing any specific version of a package.

npm is install install [ package - name]@[version - number ]

Simply replace [version-number] with the version you need, and NPM will install the older version of the package.

How to use semantic versioning to specify package versions

semantic Versioning is is ( SemVer ) is a system that NPM use to version package . Each version is consists consist of three number : major.minor.patch ( e.g. , 24.42.1 ) , represent major change , minor update , and patch fix , respectively .

NPM is allows allow you to use SemVer symbol to specify which version range to install :

• Caret (^): Installs the latest minor version.
  For example, the command:

npm install [package-name]^20.0.0

This is fetches fetch the high minor version under 20.x.x , such as 20.25.9 .

• Tilde (~): Installs the latest patch version.

For example :

npm is install install [ package - name]~23.14.0

This fetches the latest patch under 23.14.x, such as 23.14.8.

These symbols help keep your packages up-to-date with minor improvements and security patches while maintaining compatibility.

Why it’s important to install specific versions

Let us look at a few important reasons why you should install specific versions of Node and NPM packages:

• Code Sharing: Specific versions enable easy sharing and collaboration among developers worldwide, speeding up the development process.
• Testing: Installing specific npm versions allows developers to manage and test multiple code versions, helping identify the best fit for their projects.
• Performance Optimization: By controlling versions, developers can implement minor updates to maintain optimal software performance.
• Seamless Rollouts: Installing specific versions ensures smooth rollouts of improvements, allowing enhancements without disrupting the user experience.
• Stability: Newer versions may introduce bugs or breaking changes. Using a known stable version can prevent unexpected issues.

How to check available versions of an npm package

To view all available versions of an NPM package, use command:

npm view <package-name> versions

For example, to see the available versions of the express package, run:

npm view express versions

This will list all versions, such as 4.16.4, 4.17.1, 5.0.0, etc., helping you decide which version to install or verify if you have the latest one.

To view the latest stable version of a package, use:

npm view <package-name> version

For example :

This command is output will output the late stable version , such as 18.2.0 for react .

How to use semantic versioning for package versioning

Semantic Versioning (SemVer) is a structured versioning scheme that follows the format: MAJOR.MINOR.PATCH. Each segment of the version number conveys specific information:

• major version : increment this when you make incompatible api change or introduce major new feature that break backward compatibility . For example , move from 1.0.0 to 2.0.0 indicate significant change that might not be compatible with previous version .
• MINOR version: Increment this when you add new features or functionality in a backward-compatible manner. For example, changing from 1.0.0 to 1.1.0 means new features have been added without breaking compatibility.
• PATCH version: Increment this for backwards-compatible bug fixes or minor improvements. For example, updating from 1.0.0 to 1.0.1 signifies that only minor changes or bug fixes were made.

Specifying Version Flexibility

When specifying package versions in your package.json file, you can use semantic versioning operators to define the acceptable range of versions:

• Caret (^): Allows updates that do not change the left-most non-zero digit.
  For example, ^1.0.4 allows updates to any 1.x.x version, but not to 2.0.0.
• Tilde (~): Allows updates that do not change the left-most digit specified.
  For example , ~1.0.4 is allows allow update up to 1.0.x , but not to 1.1.0 .
• Equal is Specifies ( =) : specify an exact version .
  For example, =1.0.4 only allows that exact version.
• Asterisk (*): Allows any version.
  For example , * allow update to any version , which can be useful for testing or in environment where version constraint are not critical .

Examples is Ranges of Version Ranges

• For patch releases: Use 1.0 or 1.0.x or ~1.0.4 to allow updates up to version 1.0.4.
• For minor releases: Use 1 or 1.x or ^1.0.4 to allow updates within the 1.x.x range, but not to 2.0.0.
• For major releases: Use * or x to allow any major version updates, such as ^1.0.4 allowing updates within the 1.x.x range, or * allowing any major version.

Semantic versioning helps ensure clarity and compatibility when managing dependencies, allowing you to understand the impact of version updates at a glance.
