Getting started with the CLI

The Snyk Command Line Interface (CLI) helps you find and fix known vulnerabilities in your dependencies, both manually and as part of your Continuous Integration (CI) build system.

See Language Support for details about package managers and languages that the CLI supports. 

Install the Snyk CLI

  • npm – npm install -g snyk (supports node version 9 and above)

  • Homebrew – brew tap snyk/tap && brew install snyk

  • Scoop - scoop bucket add snyk https://github.com/snyk/scoop-snyk

  • A manual installer available from Snyk’s GitHub

For more detailed installation guidance and options, see Install the Snyk CLI.

 

Authenticate from the browser

To associate your Snyk account with the CLI, you must first authenticate your account. No repository permissions are needed at this stage, only your email address.

To authenticate:

  1. Run snyk auth from the CLI.

    A browser tab opens, redirecting you to authenticate the CLI for use with your account.

  2. Click Authenticate.

    The authentication ends and you can go back to your terminal to continue working.

For more authentication options and information, see Authenticate the CLI with your account.

Build your project

Before testing for vulnerabilities you must build your project, unless it has one of the following lock files:

  • package-lock.json 
  • yarn.lock  
  • Gemfile.lock  
  • paket.lock

Examples of how to build/install your project:

npm install
mvn install
gradle build
dotnet restore
dep ensure

Test for vulnerabilities

Once installed and authenticated, 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

All vulnerabilities identified are listed, including their path, and remediation guidance. To monitor your project regularly and receive ongoing notifications when new vulnerabilities are introduced, see Monitor your projects at regular intervals.

 

Monitor your project

Snyk uses monitoring to regularly test your code and notify you when new vulnerabilities are introduced. To set up your project to be monitored:

  1. Open a terminal from your project directory and run snyk monitor.

    This command takes a snapshot of your current dependencies so Snyk can regularly scan your code, and notify you about newly disclosed vulnerabilities as they are introduced, or when a previously unavailable patch or upgrade path is created.

  2. Log in to the Snyk app and navigate to the Projects page to see the latest snapshot and scan results.
