Prerequisites

npm package manager installed
TuxCare registry token — contact [email protected]
To browse available artifacts, visit TuxCare Nexus and click Sign in in the top right corner. You may need to refresh the page after logging in.

Create or update the .npmrc file
Navigate to the root directory of your Next.js project and create a .npmrc file or update it if it already exists.
Example:
```
my-nextjs-project/
├── node_modules/
├── package.json
├── .npmrc         ⚠️ ← Create it here
└── package-lock.json
```
Configure the npm registry
Use an editor of your choice (e.g., VS Code) to add the following registry address lines to the .npmrc file:
```
registry=https://registry.npmjs.org/
@els-js:registry=https://nexus.repo.tuxcare.com/repository/els_js/
//nexus.repo.tuxcare.com/repository/els_js/:_auth=${TOKEN}
```
Replace ${TOKEN} with the token you received from [email protected].
Update dependencies
Update your package.json file to replace Next.js dependencies with TuxCare-maintained packages. Choose your Next.js version below and add the dependencies and overrides entries shown.
Choose Next.js version:
```
"dependencies": {
  "next": "npm:@els-js/next@>=12.3.7-tuxcare.1"
},
"overrides": {
  "[email protected]": "npm:@els-js/next@>=12.3.7-tuxcare.1"
}
```
Refresh the project dependencies
Remove node_modules, package-lock.json, and clear the npm cache:
```
rm -rf node_modules package-lock.json && npm cache clean --force
```
Install dependencies:
```
npm install
```
The token for the TuxCare repository is automatically picked up from your .npmrc file.
Verify the setup
Use npm to list the project's dependencies and confirm that npm resolves TuxCare packages correctly:
```
npm list
```
After reviewing the dependencies, run your application to ensure everything works correctly. The npm tool identifies and resolves dependencies from the TuxCare ELS for Next.js repository.
