Når vi lager digitale tjenester må vi sikre at de kan oppfattes av alle! Det innebærer at vi gir tekst til blant annet bilder, lyd, inputelementer, knapper. Her dechiffrerer vi WCAG 1.1.1, slik at du slipper å tolke regelverket selv!​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​‍​​‌​‌‍​​‌​​‍​​​​‍‌​​​‍‌‌‍​‌​‍​​​‌​‍​​‍‌​‌​​‌‌‍​‌​‍​​‍‌‌‍​‌‌‍​‍‌‍‌‍​​‌​‍‌​​​‌‍​‌​​​‍​​​‍‌‍​‌​​​‌‍‌‍‌‍​​​​​‌‌‍‌‍​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​‍​​‌​‌‍​​‌​​‍​​​​‍‌​​​‍‌‌‍​‌​‍​​​‌​‍​​‍‌​‌​​‌‌‍​‌​‍​​‍‌‌‍​‌‌‍​‍‌‍‌‍​​‌​‍‌​​​‌‍​‌​​​‍​​​‍‌‍​‌​​​‌‍‌‍‌‍​​​​​‌‌‍‌‍​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌

A couple of years ago, a colleague and I created a small JavaScript application to toy around with some image processing techniques. I really enjoyed the project, and the other day I decided put the same functionality in my new React code. One way of doing this would be to rewrite the whole thing, and to be honest, it probably would not have been that much work. But it got me thinking, how would I go about injecting the already written code into my React application? I haven't done anything like this before, and if you haven't either, this is a blog post for you!​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌​‌​​​‍‌‍‌​​‍‌‌‍​‍‌‍​‍‌‍‌​‌‍‌‌​‍‌​‍‌​​​​‌​‍‌​‍‌​‌​​‌​​​‍‌‍‌‌​‍‌‌‍​‌​​‌‌‍‌​​‌​​‍‌​‌‌​​‍​‍‌‌‍​‌‍​​​‍​​‍‌‍​‌‌‍​‍​‍​‌‍​​‍‌​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌‍​‍‌‍‌‌‌‍‍‌‍‍​‍‌‌‍​‍‌‍​‌‍‌‍‌‌‍‌​‍‌‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‌‍‌‍‌‌‌​‍‌‍​‌‍‌‌‌‍​​‍‍‌‍​‌‌​​‌​​​‍‌‍‌‍‍‌‌‍‌​​‌​‌​​​‍‌‍‌​​‍‌‌‍​‍‌‍​‍‌‍‌​‌‍‌‌​‍‌​‍‌​​​​‌​‍‌​‍‌​‌​​‌​​​‍‌‍‌‌​‍‌‌‍​‌​​‌‌‍‌​​‌​​‍‌​‌‌​​‍​‍‌‌‍​‌‍​​​‍​​‍‌‍​‌‌‍​‍​‍​‌‍​​‍‌​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌‍‌​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍​‍‌‌
