How to update all dependencies in package.json to the latest version?

Dependencies are considered one of the crucial concepts of pub package management. Your package will need a dependency package to work. You only need to list out the immediate dependencies ( the software that is used directly by the package ) and the dependencies already defined in your pubspec

Method 1: Utilize npm-check-updates

This is the first way to upgrade all dependencies to the latest version; you can try running this command:

npm install -g npm-check-updates

Then you run the below command to examine which package the update is available in:

ncu

Result:

Checking package.json

[====================] 5/5 100%

 express 4.12.x → 4.13.x

 multer ^0.1.8 → ^1.0.1

 react-bootstrap ^0.22.6 → ^0.24.0

 react-a11y ^0.1.1 → ^0.2.6

 webpack ~1.9.10 → ~1.10.5

Once you have determined which packages are available to update, you can now run the below command:

npm install

New dependencies will be shown in the current directory meanwhile list global packages with new releases by this command:

ncu -g

Next, run the following command:

ncu -u

Then you just need to run this command:

npm update

Now all dependencies are updated to the latest version.

Method 2: Run the below command if you use npx

Here’s how to update all dependencies in package.json to the latest version if you use NPX

Run the below command if you use npx:

npx npm-check-updates

And same as on, you run command npx npm-check-updates-u to check available packages

npx npm-check-updates -u

All your dependencies can be updated at once just by running this command:

npm install

Method 3: Run the following program

# Install and use the `npm-check-updates` package.

$ npm install -g npm-check-updates

# If you agree, update package.json.

$ npm-check-updates -u

#then delete node_modules folder

rm -rf node_modules

#now you can update all package to latest version

npm install

Method 4: Upgrade single package

Run this command to get a single package updated to the latest version

npm install yourPackage@latest

And run this command if you intend to update the prismjs version.

npm install prismjs@latest

The package will be in your devDependencies if you use the command with -save-dev

npm install prismjs@latest --save-dev

With this method, all your dependencies can be upgraded to the latest version too.

Method 5: Utilize npm-upgrade

There has no difference with the npm-check-updates package, the npm-upgrade package can also help you upgrade all dependencies to the latest version by running this command

npm i npm-upgrade

Next is the npm-upgrade command:

npm-upgrade

That command will examine and force you to update each package. You will transfer no or yes, like this

Update "@angular/common" in package.json from 2.4.8 to 2.4.10? (Use arrow keys)
