Tools for Web Developers

Issue #394  (Snyk Review, CSS/HTML, Media, Vue)

The following intro is a paid product review for Snyk, a free platform and toolset for building secure cloud native apps.

Large-scale code bases with huge numbers of dependencies are the norm nowadays for many developers. One thing that's not the norm, however, is making sure our code base and associated dependencies are secure and free of vulnerabilities.

Snyk helps you find vulnerabilities in your code and dependencies

That's where Snyk (pronounced "Sneak") can play a vital role in your ongoing development and maintenance. Snyk includes the following features I'll focus on here:

These software composition analysis (SCA) tools integrate with developer tools and allow you to automatically find, fix, and prevent code vulnerabilities that can creep in through code dependencies, container packages, or modifications. You can get started with Snyk by signing in with GitHub (or another of the many supported platforms) and importing any of your projects to the Snyk dashboard.

Once your projects are imported you'll get immediate feedback on problems and vulnerabilities in your dependencies. I imported a couple of my personal projects along with two forked projects:

Snyk easily integrates with GitHub

As you can see, problems found are categorized as "High Severity" (H), "Medium Severity" (M), and "Low Severity" (L). In this case, one of my projects was flagged with five problems. Good to know! Snyk has built in prioritization scores for vulnerabilities so you'll know which ones to work on first.

You can also install and run Snyk Open Source via its CLI. Once you've installed via npm and authenticated it, run snyk test in your terminal on any directory that has a package.json (or other manifest file). The CLI will give you a run-down of your vulnerabilities similar to what I showed you above via GitHub integration.

Once a project has been scanned via the CLI tool, Snyk will also give you the option to run a Wizard that will guide you through enumerating and fixing possible vulnerabilities in your dependencies. You can also set up alerts for the project so Snyk can notify you when new vulnerabilities are found.

$ snyk test
Testing C:\example\path\...

Tested 146 dependencies for known issues, found 5 issues, 6 vulnerable paths.

You can also use the snyk monitor command in any project folder in your terminal to set up email notifications on new vulnerabilities.

Snyk integrates with a whole slew of tools including container registries, CI/CD tools, selected IDEs, platforms like Heroku, Slack, JIRA, and more.

Another feature that caught my eye is Snyk's Vulnerability Database, which is the most comprehensive such database available and is what powers both Snyk Open Source and Snyk Container. You can try it online by typing in a package name or scan through some of the recently added vulnerabilities in the database.

Snyk's Vulnerability Database
Snyk is based on the most comprehensive vulnerability database

If you're developing in a container environment (like Kubernetes, Google, Azure, etc.), Snyk likewise gives you powerful tools to detect, fix, and continuously monitor for security vulnerabilities.

To integrate Snyk with your container, login with your Snyk account, click on "Integrations" in your dashboard, then select "Container orchestrators" (for Kubernetes) or "Container Registries" for other integrations.

Snyk Container
Snyk can be integrated with multiple supported Container platforms

From there you can select your platform, fill in your account credentials, then add projects to view and monitor for vulnerabilities. Snyk will automatically scan for new vulnerabilities when a container image is rebuilt.

Similar to the commands I mentioned earlier for the CLI, Snyk Container CLI allows you to test for vulnerabilities in a container image using the snyk container test command. Or you can perform continuous monitoring using snyk container monitor command. You can read more on those in the Snyk docs.

Other great features of Snyk worth mentioning are:

  • Integration with Source Code Management tools (GitHub, BitBucket, etc.) for automatic scanning of pull/merge requests
  • CI/CD pipeline integration
  • Unlimited tests for open source projects
  • Up to 100 tests for container vulnerabilities
It's important to note that everything I've discussed here is absolutely free. Snyk also offers paid plans, but the free plan covers more than enough for many developers and teams.

You can get up and running and connected to your repositories in just a few minutes, so give Snyk a try if you're looking for ways to automate your security and vulnerability checks in your code and dependencies.

Now on to this week's tools!

CSS and HTML Tools

Type Scale Clamp Generator
Interactive tool that generates CSS using the clamp() function, for producing a type scale for your headings and other common page elements.
