There's a lot of hype about the potentials of WebAssembly in the browser right now. It elicits hopes about everything from importing new functionalities into browser based applications, to the potential (and in some circles hoped for) death of JavaScript. This talk is for folks who are curious about the real world applications and limitations of WebAssembly as it exists today. Or perhaps for individuals who have written a thing or two using WebAssembly but are now wondering how to implement major features in more complex environments. I’d like to invite listeners to come follow along the journey of some intrepid developers as they integrate the popular FFmpeg multimedia framework into a React application. I’ll discuss the various complications in conversion, and why many WebAssembly ports are not currently as simple to use as an npm install. By the end of the talk, we’ll have created a road map for how to get started adding serious functionality to an application through WebAssembly. I’ll also cover how much time to budget for getting started, some potential pitfalls, and some tips and tricks for porting over large, complicated libraries.
