This will upgrade all the version hints in the package.json file, to dependencies and devDependencies, so npm can install the new major version. To update to a new major version all the packages, install the npm-check-updates package globally: npm install -g npm-check-updates Major releases are never updated in this way because they (by definition) introduce breaking changes, and npm want to save you trouble. Running npm update wonât update the version of those. Some of those updates are major releases. Hereâs the list of a few outdated packages in one repository I didnât update for quite a while: local packages: npm list globally installed packages: npm list -g specific package: npm list .To discover new releases of the packages, you run npm outdated. If there is a new minor or patch release and we type npm update, the installed version is updated, and the package-lock.json file diligently filled with the new version. Now those 2 files tell us that we installed version 1.3.1 of cowsay, and our rule for updates is ^1.3.1, which for the npm versioning rules means that npm can update to patch and minor releases: 1.3.2, 1.4.0 and so on.Ä«ut not for major version changes that break compatibility, which means, in this example, 2.0 and higher. When you npm install cowsay, this entry is added to the package.json file: Letâs say you install cowsay, a cool command line tool that lets you make a cow say things. aliases: up, upgrade Description This command will update all the packages listed to the latest version (specified by the tag config), respecting the semver constraints of both your package and its dependencies (if they also require the same package). Npm calculates the dependencies and installs the latest available version of those as well. When you install a package using npm install, the latest available version of the package is downloaded and put in the node_modules folder, and a corresponding entry is added to the package.json and package-lock.json files that are present in your current folder. How do you update all the npm dependencies store in the package.json file, to their latest version available?
