In this tutorial, we are going to learn about how to check the version of a installed npm package and its dependencies.
Installed version of all packages
To check the installed version of all npm packages in your project, you can use the npm listcommand.
npm listOutput:
├─┬ express@4.17.1│ ├─┬ accepts@1.3.7│ │ ├─┬ mime-types@2.1.26│ │ │ └── mime-db@1.43.0│ │ └── negotiator@0.6.2│ ├── array-flatten@1.1.1│ ├─┬ body-parser@1.19.0│ │ ├── bytes@3.1.0│ │ ├── content-type@1.0.4 deduped│ │ ├── debug@2.6.9 deduped│ │ ├── depd@1.1.2 deduped│ │ ├─┬ http-errors@1.7.2│ │ │ ├── depd@1.1.2 deduped│ │ │ ├── inherits@2.0.3│ │ │ ├── setprototypeof@1.1.1 deduped│ │ │ ├── statuses@1.5.0 deduped│ │ │ └── toidentifier@1.0.0│ │ ├─┬ iconv-lite@0.4.24│ │ │ └── safer-buffer@2.1.2│ │ ├── on-finished@2.3.0 deduped│ │ ├── qs@6.7.0 dedupedNote: The npm list command doesn’t only show the installed version of packages, but also their dependencies (version).
For globally installed packages, you can use the npm list -g command.
Installed version of a particular package
To check the installed version of a particular package, you can use the npm list command by specifying a package name.
Example:
npm list expressOutput:
node-project@1.0.0 /Users/saigowtham/Desktop/node-project└── express@4.17.1If you want to check the latest version of a package available in npm repository, you can usethe npm view package-name version command.
npm view express versionOutput:
