Q:

How can you make sure your dependencies are safe ?

Answer

When writing Node.js applications, ending up with hundreds or even thousands of dependencies can easily happen.
For example, if you depend on Express, you depend on 27 other modules directly, and of course on those dependencies' as well, so manually checking all of them is not an option!


The only option is to automate the update / security audit of your dependencies. For that there are free and paid options:


1. npm outdated
2. Trace by RisingStack
3. NSP
4. GreenKeeper
5. Snyk
