Building custom plugins for your web projects doesn’t have to be complicated or tied to a single build tool. In this session, Thorsten Seyschab, Computer Scientist and Web Engineer, walks you through creating a build tool agnostic plugin. Using a real-world example, you’ll learn how to preprocess complex 3D assets like glTF files and transform them into fully type-safe TypeScript objects. Step by step, discover how to generate robust TypeScript definitions while keeping your plugin compatible with popular build tools like Vite, esbuild, Rollup, Rspack, and webpack. Whether you work with Vue, Nuxt, React, Angular, or others, this talk will give you a clear path to creating versatile plugins that fit your workflow. #WebPlugins #BuildTools #TypeScript #FrontendNation #FEN2025 #ThorstenSeyschab #WebDevelopment Make your tooling flexible and powerful—no matter your framework or bundler. 💻 Read our blog: https://frontendnation.com/blog 🎟️ Sign up for Frontend Nation 2026 to stay updated: https://frontendnation.com/ 💜 Special thanks to all our event sponsors for 2025: Diamond Sponsors AG Grid: https://www.ag-grid.com/charts/?utm_source=frontend-nation&utm_medium=logo&utm_campaign=frontend-nation-sponsorship-2025 BitterBrains: https://bitterbrains.com/ Vue School: https://vueschool.io/ Certificates.dev: https://certificates.dev/ InstantDev: https://instantdev.io/ Platinum Sponsors Cypress: https://www.cypress.io/ Sentry: https://sentry.io/signup/?utm_source=event&utm_medium=sponsored-event&utm_campaign=general-fy26q2-evergreen&utm_content=signup-frontendnation2025-signup JavaScript Cert: https://certificates.dev/javascript Vue.js Cert: https://certificates.dev/vuejs/ Angular Cert: https://certificates.dev/angular React Cert: https://certificates.dev/react Nuxt Cert: https://certificates.dev/nuxt TypeScript Cert: https://certificates.dev/typescript Agorify: https://agorify.com/ Gold Sponsors Mastering Nuxt: https://masteringnuxt.com/ Mastering Pinia: https://masteringpinia.com/ LevelUp DX: https://levelupdx.com/
