I have started learning react.
i'm not sure how to pass values between (parent-child)components when redux-connect is being used.
works well when i directly export the class without a connect
or compose
error
Type '{ dataFromParent: string; parentCallback: (data: any) => void; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Component<unknown, any, any>> & Readonly<unknown> & Readonly<{ children?: ReactNode; }>'.
Property 'dataFromParent' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<Component<unknown, any, any>> & Readonly<unknown> & Readonly<{ children?: ReactNode; }>'.
parent.tsx
<Child
dataFromParent={this.state.data}
parentCallback={this.parentCalled}

child.tsx
import React from "react";
import "./Child.css";
import TreeView from "@material-ui/lab/TreeView";

Button,
withStyles,
WithStyles,
Theme,
StyleRules,
createStyles
} from "@material-ui/core";
import { connect } from "react-redux";
import compose from "recompose/compose";
import { AppState } from "Store";
interface MyProps extends WithStyles<typeof styles> {
dataFromParent: any; // value from parent
parentCallback: (val: string) => void; // sending value to parent
}
// state
interface MyState {}
const styles = (theme: Theme): StyleRules => createStyles({});
class Child extends React.Component<MyProps, MyState> {
constructor(props: any) {
super(props);
this.state = {};
this.callParent = this.callParent.bind(this);
}
componentDidMount() {}
public callParent() {
// child to parent
this.props.parentCallback("value sent from child");
}
public render() {
return (
<div className="treeStyle">
<div> data from parent: {this.props.dataFromParent}</div>
<Button onClick={this.callParent}>
send to parent
</Button>
</div>
);
}
}
const mapStateToProps = (state: AppState) => ({});
export default compose(withStyles(styles), connect(mapStateToProps, {}))(Child);
You can achieve it without using recompose as well for example:
export default connect(mapStateToProps, mapDispatchToProps)(withStyles(styles)(Child));
Additionally you may want to change props: any
to props: MyProps
to avoid any warnings by tslint/eslint
