Failed to fetch in Nextjs

[Ivan Jose Diaz Morales]

I was working with version 0.0.22 but when updating to version 3.0.0 I get this error. I am using NextJs.

@ivajo26 Thanks for reporting - do you have a sample project to reproduce?

[3lonious]

im using Tailwind in my project... wondering if my rending probem is related toi tailwind or maybe its like what Ivajo is dealing with?

[Zachary Plata]

Sorry for the delay - do you mind trying with the latest version? Additionally check out our new guidance on preloading WASM:
https://help.rive.app/runtimes/overview/web-js/preloading-wasm

This will help especially in NextJS applications with loading in the WASM that is necessary to power Rive animations

[Ryan Parker]

It would be nice to have a next.js example app and some specific pages in the docs for next.js users since it's got a lot of adoption and many users will run into the same non-trivial issues with rive.

Also if you do happen to make an example with next.js could you include content security policy rules? The recommend guidance of using wasm-unsave-eval works in firefox but not chrome, brave, or safari. I assume they all will adopt this new rule but in the meantime it would be nice to have a recommended workaround from the rive team.

Experiencing same issue here, is there a specific loader we need to use for this?

[nyuudo]

Same issue here.
Neither importing as Rive or RiveComponent works, or importing as props or as a src, the riv files simply don't render.
I even tried the link "https://cdn.rive.app/animations/vehicles.riv" that appears in the Rive React guide and not even that renders.
Is there a proper REACT JS or NEXT JS loader ?
Maybe there's an objectiely simple and plain way but I cannot seem to find it.

I've managed to get it working in my own project like his:

import { useRive } from '@rive-app/react-canvas';

const Logo = () => {

const { RiveComponent } = useRive({

src: "/YourLogo.riv",

autoplay: true,

onLoadError: () => console.log("ERROR LOADING RIVE"),

onLoad: () => console.log("LOADED RIVE"),

})

return (

<div style={{ width: '100px', height: '100px' }}>

<RiveComponent />

</div>

);

};

//then in your page layout in the page.tsx you can place it as per usual:

return (

<div className="flex-1 flex flex-col w-full px-8 sm:max-w-md justify-center gap-2">

<Logo/>```

Just make sure to put the logo file(s) in a public folder. I'm using typescript, tailwind and App Router and I have the logo inside a public folder under the "app" folder.

Thanks for your suggestion. Finally I was able to render a riv.file. I followed the logic of your code, I just had to add the 'use client' directive to the .tsx file that invoke the riv file.

I use CSP policy, but rive needs access unpkg.com
