使用TypeScript和React键入redux表单v7 [英] Typing redux forms v7 with TypeScript and React

问题描述

我有一个简单的反应 - 还原动力形式。我希望有一个form.container.tsx和一个form.component.tsx，其中form.container.tsx包含所有与redux状态的连接减去Field的连接。我正在尝试将我的容器包装在react-redux的connect中，然后将reduxForm包装在其中，看起来像 TypeScript，redux-form和connect ：

I've got a plain react-redux-powered form. I wish for there to be a form.container.tsx and a form.component.tsx, where form.container.tsx holds all the connections to redux state minus the Field's. I'm trying to wrap my container in react-redux's connect and then wrapping reduxForm within it to look something like TypeScript, redux-form and connect:

（理想）form.container.tsx：

(ideal) form.container.tsx:

interface DummyFormContainerProps {}

export const DummyFormContainer: React.SFC<DummyFormContainerProps> = props => {
  const submitForm = (formValues: object) => {
    alert(formValues);
  };
  return (
    <DummyForm
      onSubmit={submitForm}
    />
  );
};

const mapStateToProps = (state: State) => ({});
const mapDispatchToProps = (dispatch: object) => {
  return {};
};
const mergeProps = (stateProps: State, dispatchProps: object | null, ownProps: object | void) => 
  Object.assign({}, stateProps, dispatchProps, ownProps);

const formConfiguration = {
  form: 'dummy-form',
  forceUnregisterOnUnmount: true
};

export default connect(mapStateToProps, mapDispatchToProps)(
  reduxForm(formConfiguration)(DummyFormContainer)
);

以上不起作用，但如果我拿出reduxForm（）部分，我就离开了使用没有reduxForm集成的工作容器：

The above does not work, but if I take out the reduxForm() part, I'm left with a working container with no reduxForm Integration:

（不使用reduxForm）form.container.tsx：

(working without reduxForm) form.container.tsx:

export default connect(mapStateToProps, mapDispatchToProps, mergeProps)(
  DummyFormContainer
);

我尝试使用reduxForms和connect进行不同的变化，目前都没有工作：

And I've tried different variations with reduxForms and connect, all not currently working:

（带类）form.container.tsx：

(with classes) form.container.tsx:

export class DummyFormContainer extends React.Component<DummyFormContainerProps, void> {
  submitForm = (formValues: object) => {
    alert(formValues);
  }

  render() {
    return (
      <DummyForm
        onSubmit={this.submitForm}
      />
    );
  }
}

const mapStateToProps = (state: State) => ({});
const mapDispatchToProps = (dispatch: object) => {
  return {};
};
const mergeProps = (stateProps: State, dispatchProps: object | null, ownProps: object | void) => 
  Object.assign({}, stateProps, dispatchProps, ownProps);

const formConfiguration = {
  form: 'business-registration',
};

export default connect(mapStateToProps, mapDispatchToProps, mergeProps)(
  reduxForm(formConfiguration)(DummyFormContainer) // ERROR
);

错误：

./src/modules/dummy-form/dummy-form.container.tsx
(100,32): error TS2345: Argument of type 'typeof DummyFormContainer' is not assignable to parameter of type 'ComponentType<InjectedFormProps<{}, {}>>'.
  Type 'typeof DummyFormContainer' is not assignable to type 'StatelessComponent<InjectedFormProps<{}, {}>>'.
    Type 'typeof DummyFormContainer' provides no match for the signature '(props: InjectedFormProps<{}, {}> & { children?: ReactNode; }, context?: any): ReactElement<any> | null'.

（使用无状态功能组件）form.container.tsx：

(with stateless functional components) form.container.tsx:

export const DummyFormContainer: React.SFC<DummyFormContainerProps> = props => {
  const submitForm = (formValues: object) => {
    alert(formValues);
  };
  return (
    <DummyForm
      onSubmit={submitForm}
    />
  );
};

export default connect(mapStateToProps, mapDispatchToProps, mergeProps)(
  reduxForm(formConfiguration)(DummyFormContainer) // ERROR
);

错误：

./src/modules/dummy-form/dummy-form.container.tsx
(100,3): error TS2345: Argument of type 'DecoratedComponentClass<{}, Partial<ConfigProps<{}, {}>>>' is not assignable to parameter of type 'ComponentType<(State & null & void) | (State & null & object) | (State & object & void) | (State ...'.
  Type 'DecoratedComponentClass<{}, Partial<ConfigProps<{}, {}>>>' is not assignable to type 'StatelessComponent<(State & null & void) | (State & null & object) | (State & object & void) | (S...'.
    Type 'DecoratedComponentClass<{}, Partial<ConfigProps<{}, {}>>>' provides no match for the signature '(props: (State & null & void & { children?: ReactNode; }) | (State & null & object & { children?: ReactNode; }) | (State & object & void & { children?: ReactNode; }) | (State & object & { children?: ReactNode; }), context?: any): ReactElement<any> | null'.

form.component.tsx如下所示：

The form.component.tsx looks like this:

import * as React from 'react';
import Input from '../../components/input';

interface DummyFormProps {
  onSubmit: (formValues: object) => void
}

export const DummyForm: React.SFC<DummyFormProps> = () => {
  return (
    <div>
      <h1>DummyForm (no state)</h1>
      <form>
        <Input inputType="primary" />
      </form>
    </div>
  );
};

export default DummyForm;

< Input> component是一个常规的React组件。

And the < Input > component is a regular React component.

有谁知道如何正确连接reduxForm和react-redux的connect（）？

Does anyone know how to properly connect reduxForm and react-redux's connect()?

推荐答案

我也遇到了这个问题，尝试从redux状态初始化我的表单，按照 https://redux-form.com/7.0.4/examples/initializefromstate/

I also ran into this issue trying to initialise my form from redux state, as per the example in https://redux-form.com/7.0.4/examples/initializefromstate/

我最终通过连接更高级别的组件来解决这个问题，例如：

I ended up getting around it by connecting the component at a higher level, eg:

component.tsx：

component.tsx:

interface DummyFormComponentProps {} extends InjectedFormProps

const DummyFormComponent: React.SFC<DummyFormComponentProps> = props => {
  return (
    <form onSubmit={props.handleSubmit}>
      // Fields go here
    </form>
  )
}

export const DummyForm = reduxForm({
  form: "dummy-form"
})(DummyFormComponent)

// Trying to connect here also gave errors with DecoratedComponentClass

container.tsx：

container.tsx:

interface DummyFormContainerProps {} extends Pick<InjectedFormProps,
  "initialValues"
>

const submitForm = (formValues: object) => {
  alert(formValues);
};

const DummyFormContainer: React.SFC<DummyFormContainerProps> = props => {  
  return (
    <DummyForm 
      initialValues={props.initialValues}
      onSubmit={submitForm}
    />
  )
}

const mapStateToProps = (state: State) => ({
  initialValues: {}
});
const mapDispatchToProps = (dispatch: object) => {
  return {};
};
export default connect(mapStateToProps, mapDispatchToProps)(DummyFormContainer)
