Rethinking Boundaries in the JavaScript Ecosystem

In recent years, tools in the JavaScript ecosystem have evolved beyond their traditional roles. As individual tools take on a broader range of responsibilities, the boundaries between them are becoming increasingly blurred.

How much should a single tool take on, and what should it leave to other tools or to standards? How can we reconcile preserving compatibility with creating unique value, and technical progress with sustaining an open ecosystem?

In this panel discussion, our panelists will explore where the JavaScript ecosystem stands today and where it may be headed next, through the lens of the boundaries between tools, between implementations and standards, and between projects and communities.

Please note that this workshop will be held in Japanese only.

Have you ever used a frontend framework like Vue.js or React and wondered, “What’s actually happening under the hood?”

In this hands-on workshop, we’ll explore how frontend frameworks work using chibivue, a learning resource designed to help you understand the internals of Vue.js.

By implementing key concepts such as reactivity and the Virtual DOM yourself, you’ll get a firsthand look at what’s usually hidden behind the libraries and frameworks you use every day. Through this experience, you’ll gain a deeper understanding of how frontend frameworks work under the hood.

Whether you’re a Vue.js user or work with another framework such as React, there’s something here for everyone. Once you understand how things work behind the scenes, the frameworks you use every day may start to feel a little more familiar—and a lot more interesting.

At Vue Fes Japan 2026, we have created a special program to support and inspire students who will lead the future of our tech community.

It is a great opportunity to connect with other students who share your passion for front-end development. You can also enjoy talking with Vue.js community members, engineers at the heart of the OSS world, and professionals from our Student Support Sponsor companies.

The program features lightning talks by sponsor companies along with casual networking sessions where you can chat about technology and career paths. We hope this will be a chance for you to get real-world advice on learning and community involvement directly from experienced engineers.

We look forward to seeing your time at Vue Fes Japan 2026 turn into new insights and meaningful connections. See you there!

【Note】

This event is part of the Student Support Program. Only students who have been accepted through the application process can participate.

Got a question about frontend, development tools, or your career? Maybe there’s something you’ve been wondering about, but it feels too small to go out of your way to ask.

The “Ask Anything Board” is a Q&A board created by everyone at the event. Write down your questions or concerns on a sticky note and post them on the board—you might find that someone at the venue has an answer, some advice, or an experience to share.

Whether you’re asking a question, sharing an answer, or just stopping by to see what others are talking about, everyone is welcome! Let’s bring together the knowledge and experiences of the Vue Fes Japan community and enjoy new discoveries and connections.
