Fast refresh failing when dynamically importing components in Vite using React and typescript
I am trying to create a multistep form, I have my data in a separate file for constants like this
import { lazy } from 'react';
export const steps = [
{
id: 0,
name: 'Personal Info',
component: lazy(() => import('../components/PersonalInfo')),
},
];
I pass it to a custom hook in a context
const dataSteps = useMultiStep(steps);
const { next, back, currentStep, isFirst } = dataSteps;
This is the customhook
import { useState } from 'react';
import { MultistepProps } from '../@types/Multiform';
const useMultiStep = (steps: MultistepProps[]) => {
const [step, setStep] = useState(0);
const isLast = step === steps?.length - 1;
const isFirst = step === 0;
const next = (): void => {
if (isLast) return;
setStep((current) => current + 1);
};
const back = (): void => {
if (isFirst) return;
setStep((current) => current - 1);
};
return {
step,
next,
back,
currentStep: steps[step],
isFirst,
};
};
export default useMultiStep;
I use the dynamically components here
import FormInterface from './interface/FormInterface';
import useApp from './hooks/useApp';
import { Suspense } from 'react';
function App() {
const data = useApp();
const { currentStep, next, back, isFirst } = data;
const handleSubmit = (e: React.FormEvent) => {
e.preventDefault();
next();
};
return (
<FormInterface>
<form
onSubmit={handleSubmit}
className="flex flex-col h-full py-5 group"
noValidate={true}
>
{currentStep.component && (
<>
<h1 className="text-3xl font-bold text-marineBlue">
{currentStep?.name}
</h1>
<Suspense fallback={<div>Loading...</div>}>
<currentStep.component /> //here
</Suspense>
<div
className={`mt-4 sm:mt-auto flex ${
isFirst ? 'justify-end' : 'justify-between'
}`}
>
<button
type="button"
className={`hover:text-marineBlue font-bold text-coolGray py-2 px-5 rounded-md text-[13px] ${
isFirst ? 'hidden' : 'block'
}`}
onClick={back}
>
Go Back
</button>
<button
type="submit"
className="hover:bg-purplishBlue bg-marineBlue text-white py-2 px-5 rounded-md text-[12px] group-invalid:pointer-events-none group-invalid:opacity-30 self-end"
>
Next Step
</button>
</div>
</>
)}
</form>
</FormInterface>
);
}
export default App;
My vite config is this
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
// https://vitejs.dev/config/
export default defineConfig({
plugins: [react()],
});
After trying EVERYTHING I still get this errors not the first renders but when the component reloads
App.tsx:7 Uncaught TypeError: Cannot destructure property 'currentStep' of 'data' as it is null. at App (App.tsx:7:11) at renderWithHooks (react-dom.development.js:16305:18) at mountIndeterminateComponent (react-dom.development.js:20074:13) at beginWork (react-dom.development.js:21587:16) at HTMLUnknownElement.callCallback2 (react-dom.development.js:4164:14) at Object.invokeGuardedCallbackDev (react-dom.development.js:4213:16) at invokeGuardedCallback (react-dom.development.js:4277:31) at beginWork$1 (react-dom.development.js:27451:7) at performUnitOfWork (react-dom.development.js:26557:12) at workLoopSync (react-dom.development.js:26466:5)
I believe it's a HRM issue since it's like loading the whole page insted of only the component, for that the states are lost and the info on the useMultisteps
is lost but I just can't find a way to make it work, please help me our teach me a better way to accomplish what I am trying to do
