I'm currently developing a tool for my frontend team which is facing a challenge when it comes to displaying 'Loading Skeletons' and 'Error Toasts'. The issue is that our local API is extremely fast, so they can't realistically test these states. Right now, their solution is to hardcode delays in their fetch requests or use Mock Service Worker (MSW), but they find it cumbersome to maintain. I'm wondering what other methods are out there? Would a simple URL that allows toggling options like 'Delay 3s' or 'Force 500 Error' through a dashboard be practical, or is that too much?

Honestly, the simplest approach is to just manually set the loading state to true. When you’re ready, you can just remove the hardcoding, and voilà! It gets the job done without any extra tools involved.
Definitely! Keeping it simple is often the way to go.
There are definitely simpler solutions than building a whole dashboard. You can just set a dev-only flag to simulate delays or errors without burdening the component code. This way, it remains centralized and easy to manage without the clutter of fake delays in your production code.
That's a neat approach! Keeping it centralized helps avoid confusion down the line.
Yeah, you can even use environment variables to control the delays. Makes testing smooth!
For more advanced simulations, Storybook can be incredibly useful for mocking various states. Plus, you can manipulate parameters like response time or test failures on the fly, which could really streamline the development process for your team.
Great point! Storybook’s setup for handling user interface states is amazing!
For sure! It’s like a playground for component testing, and you can focus on the UI without backend constraints!
One way to tackle this is by using network throttling in your browser's dev tools. It’s super easy and doesn’t require any additional tools or configs. For error states, sometimes I just simulate an error by throwing one in the fetch call temporarily while styling. This avoids any complicated setup, and you can turn it off whenever you’re done. I think a full dashboard is a bit excessive since the tools are readily available in browsers!
Totally agree! Throttling is quick to toggle and works perfectly for loading states. Just remember to throw in some mock errors when needed!
Exactly! Plus, Chrome allows you to mock fetch responses directly, which is a game-changer.
Using mock APIs is another effective way to simulate different states. For example, you could set up a JSON server to provide dummy responses that can include errors, which definitely allows more flexible testing without the need to hit the backend.
Oh, JSON server is fantastic! It means no actual backend interactions needed while developing.
I actually used to set it up in my mocks too. It's super helpful!

True that! Sometimes the most straightforward solutions are the best.
