SEATTLE, WA – October 2025 – NodeSource, a global leader in Node.js observability and performance, today announced its active collaboration in the modernization of Express.js, one of the most widely used and trusted frameworks in the JavaScript ecosystem.
Express.js has been a cornerstone of web development for over a decade, powering millions of applications and APIs across the globe. As part of the ongoing effort to ensure its long-term sustainability, security, and performance, the project has entered a new phase of modernization, focused on updating its governance model, refreshing its core architecture, and optimizing it for today’s Node.js runtime.
Through this collaboration, NodeSource has provided technical expertise, runtime performance insights, and data-driven guidance via N|Solid, helping enhance Express.js for its maintainers and the broader developer community.
“Express.js continues to be a foundational part of the Node.js ecosystem, and our goal is to help ensure it remains performant and sustainable for the next generation of developers,” said Ulises Gascón, express maintainer and Engineer at NodeSource. “We’re proud in in this modernization effort, bringing the experience we’ve gained from years of working on Node.js runtime performance.”
The modernization initiative aims to make Express.js lighter, faster, and easier to maintain, while preserving the simplicity that has made it a favorite among developers. NodeSource’s contributions are part of its broader commitment to strengthening open-source foundations that power the JavaScript ecosystem.
Earlier this month, Express.js maintainer Ulises Gascón shared that the project is being actively refactored to align with modern Node.js APIs, improve compatibility with async/await patterns, and reduce technical debt accumulated over years of widespread adoption. NodeSource has been collaborating closely in reviewing performance bottlenecks, modernizing the framework’s internals, and ensuring forward compatibility with new Node.js versions.
"Partnering with NodeSource in the Express Performance Working Group has been amazing. They have stepped up to help us integrate performance analysis tooling, plan to help build dashboards, and have generally been great contributors. They really understand how to be great members of our ecosystem while also running a product team.” Wess Todd – Express TC Member
