How to Resolve \'TypeError: Cannot Read Properties of Undefined (reading \'push\')\' When Attempting to Redirect in React Router v6?

Navigating Programmatically with React Router v6: Resolving TypeError

Problem

Encountering the error message "TypeError: Cannot read properties of undefined (reading 'push')" when attempting to redirect after a user action, such as clicking a submit button. This indicates that the navigate prop used for the redirection is undefined.

Solution

1. Convert to a Function Component

Use the useNavigate hook for navigation within a function component. This hook is only compatible with function components.

2. Create a Custom HOC for Class Components

Custom withRouter HOC:

const withRouter = WrappedComponent => props => {
  const navigate = useNavigate();
  // etc... other react-router-dom v6 hooks

  return (
    <WrappedComponent
      {...props}
      navigate={navigate}
      // etc...
    />
  );
};

Decorate the Class Component:

export default withRouter(AddContacts);

3. Use the Navigate Function

Use the navigate function for navigation instead of the history object used in previous versions of React Router. The syntax has changed to:

this.props.navigate("/path");

Complete working code for AddContacts.js:

import React, { Component } from "react";
import { Consumer } from "../../context";
import TextInputGroup from "../layout/TextInputGroup";
import { v4 as uuidv4 } from "uuid";
import withRouter from "./withRouter"; // Custom HOC

class AddContacts extends Component {
  state = {
    name: "",
    email: "",
    phone: "",
    errors: {},
  };

  onSubmit = (dispatch, e) => {
    e.preventDefault();

    const { name, email, phone } = this.state;

    //Check for errors

    if (name === "") {
      this.setState({ errors: { name: "Name is required" } });
      return;
    }
    if (email === "") {
      this.setState({ errors: { email: "Email is required" } });
      return;
    }
    if (phone === "") {
      this.setState({ errors: { phone: "Phone is required" } });
      return;
    }

    const newContact = {
      id: uuidv4(),
      name,
      email,
      phone,
    };
    dispatch({ type: "ADD_CONTACT", payload: newContact });

    this.setState({
      name: "",
      email: "",
      phone: "",
      errors: {},
    });
    this.props.navigate("/"); // Navigate using custom HOC
  };

  onChange = (e) => this.setState({ [e.target.name]: e.target.value });
  render() {
    const { name, email, phone, errors } = this.state;

    return (
      <Consumer>
        {(value) => {
          const { dispatch } = value;

          return (
            <div className="card mb-3">
              <div className="card-header">Add Contacts</div>
              <div className="card-body">
                <form onSubmit={this.onSubmit.bind(this, dispatch)}>
                  <TextInputGroup
                    label="Name"
                    name="name"
                    placeholder="Enter Name..."
                    value={name}
                    onChange={this.onChange}
                    error={errors.name}
                  />
                  <TextInputGroup
                    label="Email"
                    name="email"
                    type="email"
                    placeholder="Enter Email..."
                    value={email}
                    onChange={this.onChange}
                    error={errors.email}
                  />
                  <TextInputGroup
                    label="Phone"
                    name="phone"
                    placeholder="Enter Phone..."
                    value={phone}
                    onChange={this.onChange}
                    error={errors.phone}
                  />
                  <input
                    type="submit"
                    value="Add Contact"
                    className="btn btn-light btn-block mt-3"
                  />
                </form>
              </div>
            </div>
          );
        }}
      </Consumer>
    );
  }
}

export default withRouter(AddContacts); // Export wrapped component

This solution allows for navigation from class components in React Router v6, despite the initial error indicating an undefined navigation prop.
