reactjs - Hot reloading u Storybooku uzrokuje grešku kod hookova

Dobivam sljedeću pogrešku kada se moj Storybook ponovno učitava uživo. Na prvom učitavanju radi savršeno:

TypeError: Cannot read property 'hooks' of undefined

Koristim redux provider, iako nisam siguran je li to povezano. Kod i priče izgledaju ovako bez obzira:

// provider.tsx
const Provider: React.FC = ({ children }) => (
    <ThemeProvider theme={theme}>
        <Provider store={store}>
            <Router>
                {children}
            </Router>
        </Provider>
    </ThemeProvider>
)

export default Provider


// decorators.tsx
export const withProvider = (storyFn: any) => <Provider>
    {storyFn()}
</Provider>


// 2-TodoCard.stories.tsx
const complete = () => <TodoCard todo={completeTodo} />  // the TodoCard is just a React.FC
const incomplete = () => <TodoCard todo={incompleteTodo} />

storiesOf('TodoCard', module)
    .addDecorator(withProvider)
    .add('complete', complete)
    .add('incomplete', incomplete)

webpack.config.js (unutra u .storybook/ - normalna aplikacija koristi zadani create-react-app webpack):

module.exports = ({ config }) => {
    config.module.rules.push({
        test: /\.(ts|tsx)$/,
        use: [
            {
                loader: require.resolve('awesome-typescript-loader'),
            },
            // Optional
            {
                loader: require.resolve('react-docgen-typescript-loader'),
            },
        ],
    });
    config.resolve.extensions.push('.ts', '.tsx');
    // config.entry = config.entry.filter(singleEntry => !singleEntry.includes('/webpack-hot-middleware/'));  // hot reloading causing a hooks bug
    return config;
};

Odgovor #1

Ovo mi se dogodilo kada sam uređivao svoju .storybook/config.js datoteku i nisam ponovno pokrenuo Storybook server. Kada sam ga zaustavio i ponovno pokrenuo, ova je pogreška nestala.

Odgovor #2

Ispostavilo se da je pogreška nastala zbog toga što sam koristio dva različita formata pisanja priča, dok sam trebao koristiti jedan ili drugi.

Da citiram korisnika Hypnosphi,

@wgpsutherland Izgleda da miješate Component Story Format i storiesOf API u svojim pričama:

export default {
    title: 'Button',
};

storiesOf('Button', module)
    .add('gray', () => <Button color='gray' fluid size='large' type='submit'>Add</Button>)
    .add('blue', () => <Button color='blue' fluid size='large' type='submit'>Add</Button>)

Moraš odabrati jedan. Dakle, trebao bi biti ili

export default {
    title: 'Button',
};

export const gray = () => <Button color='gray' fluid size='large' type='submit'>Add</Button>
export const blue = () => <Button color='blue' fluid size='large' type='submit'>Add</Button>

ili

storiesOf('Button', module)
    .add('gray', () => <Button color='gray' fluid size='large' type='submit'>Add</Button>)
    .add('blue', () => <Button color='blue' fluid size='large' type='submit'>Add</Button>)
