Node.js Security optimizations

In the following post, we are going to discuss crucial Node.js security improvements. The platform itself is not very risky, so all major security problems are caused by its popularity and extensive use. As a result, sloppy coding makes projects absolutely unreliable, but you can easily avoid common Node.js security problems, and you will do so with core Node.js security improvements, resources, and tools listed below.


Since Node.js is based on JavaScript, the platform inherits JavaScript’s security problems as well, but they might be entirely different since all the processes are executed on the server instead of the browser. For instance, in case of Node.js the eval security issue, common for client side in JS projects, exists on the server side, and the appropriate function increases the risk of running malicious code there.

Node.js Security Improvements: Reporting a Bug

Node.js Security Improvements

First of all, it is necessary to mention that the whole Node.js community makes the platform better. If you find a security bugs in Node.js, tell about the issue by emailing security at The core team will receive your message and fix the problem, keeping you informed of the progress related to a fix. As a result, you will receive an update within five days.

As for security bugs related to third party modules, you should inform their developers about discovered problems. Besides, it is possible to utilize the Node Security Project.

Node.js Security Improvements: Receiving Updates

Node.js Security Optimizations

If you want to keep your Node.js projects secure, it is necessary to implement all recent updates. Node.js distributes such updates via a Google+ group and a blog. Always check both sources to keep up with the times.

Node.js Security Improvements: Node Security Project

Node.js Security Improvements with Node Security Project

The aforementioned Node Security Project is one of the most important security sources on the platform. All core Node.js security improvements are available there in a form of various tools. Besides, you will find a list of resources and articles about Node.js security there. And you can easily contribute to the project as well.

Node.js Security Improvements: Tools

Development Environment for Node.js

  • nsp is the Node Security Project command line interface that provides the ability to audit both package.json and npm-shrinkwrap.json files against the API. The tool is vital if you are going to implement Node.js security improvements, because it identifies known vulnerabilities. In addition, you will get access to recent news about the security of the platform.
  • vscode-nsp is your nsp for Visual Studio Code.
  • gulp-nsp is your nsp for Gulp.
  • grunt-nsp is your nsp for Grunt.
  • npm-utils is a set of npm utilities for Node.js.
  • eslint-plugin-security is a set of ESLint rules for Node.js security projects. Although the project helps to identify potential security issues, all improvements should be performed manually.
  • eslint-config-nodesecurity offers a base set of ESLint rules for the same purpose.
  • demo provides different vulnerable dependencies necessary for further security improvements.
