How to redirect in axios?

Question

Can I redirect in .then instead of console.log?

axios
  .post('/api/users/login', user)
  .then(res => console.log(res.data))
  .catch(err => this.setState({ errors: err.response.data }))

Is it possible and if it is how can I do it?

Answer 1

I would suggest that you should not perform side operations inside the actions (in this case axios call). This is because you would eventually add these calls inside redux thunk/saga or some other middleware.

The pattern which I follow is you return the promise and add the redirection logic inside your components(or containers). Following are the benefits of it:-

1. It makes your code cleaner and avoids side affects inside your API calls.
2. It makes easier to test your API calls using mock data.
3. Showing alert in case the API fails without passing callback as function parameter.

Now, that being said you can use the above logic in following ways:-

// Component code

import { browserHistory } from 'react-router';

class TestContainer extends React.Component {
  auth = () => {
    login()
    .then(() => {
      browserHistory.push("/addUser");
    })
    .catch(() => {
      // Show alert to user;
    })
  }
  
  render () {
    return (
      <div>
        <button onClick={this.auth}>Auth</button>
      </div>
    );
  }
}

// Action code 

const login = () => {
  return axios
  .post('/api/users/login', user);
}
