Wasm I/O 2025 - Barcelona, 27-28 March Slides: https://2025.wasm.io/slides/giving-low-code-to-web-with-webassembly-velneos-success-story-wasmio25.pdf In this talk, we will explore how Velneo implemented WebAssembly to bring its applications to the web environment. Through a practical approach, I will demonstrate how we combined WebAssembly with C++ and Qt to develop a comprehensive ecosystem that includes a database manager, a server administrator, and an application editor. Attendees will understand the benefits and challenges of this implementation, offering valuable insights for any developer looking to leverage WebAssembly.
