P.S. If you’re looking for something specific to listen to, the music by famed Norwegian tracker Jogeir Liljedahl is well worth a try – particularly Overture or Guitar Slinger.

Announcing The NodeSource-GitHub Partnership

NODESOURCE PARTNERS WITH GITHUB
For Immediate Release

NodeSource enhances Node.js application security with the NCM integration for GitHub Deployment Protection Rules.

[Seattle, WA, April 13th, 2023] – NodeSource, a leader in Node.js application management, monitoring, and security, is excited to announce our partnership as a launch partner for Deployment Protection Rules with GitHub Actions, the world’s largest software development platform, to integrate Node Certified Modules (NCM) directly into the GitHub Marketplace. This integration brings enhanced security capabilities to the development process in Node.js applications, mitigating vulnerabilities and ensuring compliance with licensing requirements.

Node.js applications and services heavily rely on open-source Node packages for their source code. However, many of these packages may have publicly disclosed vulnerabilities often ignored or overlooked by developers, leaving applications at risk of malicious code execution and data leaks. To address this challenge, NodeSource has developed NCM, a powerful tool that scans for vulnerabilities, tracks package dependencies, and ensures compliance with licensing requirements.

“By enabling partners like NodeSource to create Deployment Protection Rules for users of GitHub Actions, organizations can now leverage NodeSource’s vulnerability management tools to identify security risks and maintain compliance before their applications are deployed to production. These improvements and new controls underscore GitHub’s commitment to empowering developers while enhancing governance, code quality, and security within GitHub Actions.” – Jamie Jones, GitHub VP of Technical Partnerships & Field Services. With NCM GitHub App for [Deployment ProtectionRules]https://github.blog/2023-04-20-announcing-github-actions-deployment-protection-rules-now-in-public-beta, developers can easily add NCM to their repositories, configure organization-wide rules for vulnerability scanning and approval processes.

With the integration of NCM for GitHub Deployment Protection Rules, users can now easily add and configure the NCM app into their GitHub repositories. This allows developers to seamlessly incorporate NCM into their workflow, with every deployment being analyzed and approved or rejected based on organization-configured rules for NCM. NCM provides a comprehensive report for every Pull Request, helping developers identify and mitigate security risks during code reviews. Check the NCM GitHub App.

“NodeSource is committed to providing the Node.js community with the tools and capabilities needed to secure their applications and mitigate risks associated with open-source packages,” said __Russ Whitman, CEO of NodeSource__. “Our partnership with GitHub further strengthens our mission, allowing users to easily access and utilize NCM within their GitHub Actions workflow, ensuring that their Node.js applications remain secure and reliable.”

NodeSource’s NCM also works offline, providing flexibility and convenience for developers in various development environments. NCM offers a comprehensive solution for managing Node.js application dependencies and assessing security vulnerabilities, license concerns, code risks, and code quality.

“Security is a top priority for NodeSource and our community of developers. We are thrilled to be a launch partner for GitHub Deployment Protection Rules and integrate NCM into GitHub Actions, providing our users with a powerful tool for securing their Node.js applications,” said __Adrian Estrada, VP of Technology of NodeSource__. “With NCM’s capabilities seamlessly integrated into GitHub Deployment Protection Rules, developers can now easily track and manage their package dependencies, ensuring that their applications remain secure and compliant.”

Node.js application security is of utmost importance, especially in today’s threat landscape, where supply chain attacks are becoming more prevalent. By leveraging NCM’s capabilities within their GitHub Actions workflows, developers can significantly reduce the risk of vulnerabilities in their Node.js applications, ensuring that their codebase remains secure and reliable.

About NodeSource:

NodeSource is a leading provider of Node.js application management solutions, Node.js Support and services, helping organizations successfully scale and secure their Node.js applications. Node Certified Modules (NCM) is a comprehensive tool that offers visibility, security, and governance for managing Node.js application dependencies. With its powerful features, NCM ensures that Node.js applications remain secure, reliable, and compliant with licensing requirements. For more information, visit www.nodesource.com.

About GitHub:

GitHub is the world’s largest software development platform, providing a collaborative environment for millions of developers to build, test, and deploy their software. GitHub offers many tools and integrations for efficient software development and secure collaboration. For more information, visit www.github.com.

Speeding Up the JavaScript Ecosystem: npm Scripts — The latest in what has been a fascinating series on finding ‘low hanging fruit’ when it comes to performance in the JavaScript world. The author explains it best himself:

“‘npm scripts’ are executed by JavaScript developers … all the time. Despite their high usage they are not particularly well optimized and add about 400ms of overhead. In this article we were able to bring that down to ~22ms.”
What Marvin does here is a valuable skill for all developers to pick up, and you can enjoy more by going back to the start.
