How to update all Node.js dependencies to their latest version ?

To update all Node.js dependencies to their latest versions, you can use the npm (Node Package Manager) command-line tool. First, navigate to your project's root directory. Then, run the following command to update all dependencies:

npx npm-check-updates -u
npm install

How Packages Become Dependencies? 

When you install a package using npm install <packagename>, the latest version is downloaded to the node_modules folder. A corresponding entry is added to package.json and package-lock.json in the current folder. npm determines the dependencies and installs their latest versions as well. To discover new package releases, use npm outdated.

Some of those updates are major releases. Running an npm update won't help here. Major releases are never updated in this way because they (by definition) introduce breaking changes, and npm wants to save you trouble.

Update All Packages to the Latest Version: Our old package.json looks like this:

{
 "dependencies": {
 "express": "^3.0.0",
 "next": "^13.1.4",
 "react": "^18.0.0",
 "webpack": "5.5.x"
 }
}

Leveraging npm-check-updates, you can upgrade all package.json dependencies to the latest version.

• Install the npm-check-updates package globally.

npm install -g npm-check-updates

• Now run npm-check-updates to upgrade all version hints in package.json, allowing installation of the new major versions:

ncu -u

Note: A slightly less intrusive (avoids a global install) way of doing this if you have a modern version of npm is:

npm install npm-check-updates

And then run the update command:

npx npm-check-updates -u

• Finally, run a standard install:

npm install

And, we are with our new updatedpackage.json which is as follows:

{
 "dependencies": {
 "express": "^4.18.2",
 "next": "^13.1.6",
 "react": "^18.2.0",
 "webpack": "5.75.x"
 }
}
