After installation, import the Poll component from react-polls dependency and start using it by passing the required props: question, answer and onVote. See User Guide section for more information about props.

import Poll from 'react-polls';

// Declaring poll question and answers
const pollQuestion = 'Is react-polls useful?'
const pollAnswers = [
  { option: 'Yes', votes: 8 },
  { option: 'No', votes: 2 }
]

class App extends Component {
  // Setting answers to state to reload the component with each vote
  state = {
    pollAnswers: [...pollAnswers]
  }

  // Handling user vote
  // Increments the votes count of answer when the user votes
  handleVote = voteAnswer => {
    const { pollAnswers } = this.state
    const newPollAnswers = pollAnswers.map(answer => {
      if (answer.option === voteAnswer) answer.votes++
      return answer
    })
    this.setState({
      pollAnswers: newPollAnswers
    })
  }

  render () {
    const { pollAnswers } = this.state
    return (
      <div>
        <Poll question={pollQuestion} answers={pollAnswers} onVote={this.handleVote} />
      </div>
    );
