Ever noticed how your window resize listener feels a little blind? It's because it only reacts when the window changes. But in modern layouts, elements like sidebars or flex containers change size all the time. That's why your charts end up looking squashed or just broken. So instead, use Resize Observer. Just grab the element you want to watch, like your chart container in this case. Then create a Resize Observer and pass in a function that runs whenever the size changes. Now inside that function, you get something called entries, which is basically a list of changes. From there, take the first entry, go into content rect, and grab the width, which is what we care about. So whenever that width changes, you just redraw your chart using that value, then start observing the element. And now, anytime that container resizes, your chart updates instantly. That's how platforms like YouTube keep their video players If this helped, follow for more Dev Tips and comment code if you want the full demo.
