Install the Snyk CLI

Install our Snyk CLI tool using npm.

Prerequisites:

• Ensure you’ve installed the latest version of npm on your local environment, using Node version 10 or later (see What version of Node is required for Snyk?).
• To run Snyk on Alpine Linux, first install libstdc++. See this doc for more help.

Steps:

Run these commands to install it for local use:

npm install -g snyk

Once installed, you need to authenticate with your Snyk account:

snyk auth

To test your installation change directory into a folder containing a supported package manifest file (package.json, pom.xml, composer.lock, etc.) and run:

cd /my/project/
snyk test

Alternatively, you can perform a quick test on a public npm package, for instance:

snyk test ionic

As you can see, Snyk found and reported several vulnerabilities in the package. For each issue found, Snyk provides the severity of the issue, a link to a detailed description, the path through which the vulnerable module got into your system, and guidance on how to fix the problem.

You can download and use Snyk's prebuilt binaries already containing npm, the Snyk CLI and other necessary components. To download the prebuilt binary, visit the Releases tab in the CLI repository page in GitHub:

Once you've completed installation, get started testing and remediating your vulnerabilities with our Getting started guide and our full list of our CLI commands, options and arguments.
