Solved: update all packages

Sure, let’s get started.

The rapid evolution of technology brings changes in software development rapidly. As a result, keeping track of all software packages to be on the latest version is often seen as an intimidating task for developers. However, updating all packages is crucial for the stability, security, and speed of a web application. In JavaScript, various powerful tools can automate these tasks and simplify the overall experience. In this guide, we will focus on updating all packages in a JavaScript project using npm (node package manager), one of the most common package managers in the JavaScript ecosystem.

npm makes it easy to manage packages for a project in an organized way. However, when multiple packages are involved, manual checking and updating can be tiresome. Luckily, npm provides ways to check outdated packages and update them all at once.

Updating Packages with npm

To update all packages:

  • First, remember to open the terminal in the root directory of your project.
  • Then, run the command
    npm outdated

    . This will display a table in the terminal listing all outdated packages, the current version you have, the latest version available, etc.

  • Next, to update all packages to their latest versions, run
    npm update


  • Alternatively, to update a specific package, use
    npm install <package>@latest


Remember, always test your application thoroughly after updates to ensure everything is working as expected.

Using Utilities for Easier Updates

There are utilities that can make the package update process simpler. One popular tool is npm-check-updates, known as ncu. To get started with ncu:

  • First, we install it globally with
    npm install -g npm-check-updates


  • Then, we can list all new dependencies for the project by running


  • Finally, to update all the packages, run
    ncu -u

    . This upgrades your package.json file to use the latest version of each package, followed by

    npm install

    to install the updated packages.

Remember, similar to npm update, always ensure your application functions as expected after the updates.

Paying attention to Dependency Types

JavaScript applications usually have two types of dependencies – dependencies and devDependencies. The former are needed for the application to run, while the latter are only needed in the development phase. When updating packages, understanding these dependencies is crucial to maintain the performance and stability of your application.

Let this guide serve as a roadmap for your journey towards mastering the art of package updates. The process can indeed seem intimidating at first, but with a bit of practice, it becomes second nature. Happy coding!
