First off, not sure you want to do this in your componentWillMount, it's better to have it in componentDidMount and have some default states that will update once done with these requests. Second, you want to limit the number of setStates you write because they might cause additional re-renders, here is a solution using async/await:
async componentDidMount() {
// Make first two requests
const [firstResponse, secondResponse] = await Promise.all([
axios.get(`https://maps.googleapis.com/maps/api/geocode/json?&address=${this.props.p1}`),
axios.get(`https://maps.googleapis.com/maps/api/geocode/json?&address=${this.props.p2}`)
]);
// Make third request using responses from the first two
const thirdResponse = await axios.get('https://maps.googleapis.com/maps/api/directions/json?origin=place_id:' + firstResponse.data.results.place_id + '&destination=place_id:' + secondResponse.data.results.place_id + '&key=' + 'API-KEY-HIDDEN');
// Update state once with all 3 responses
this.setState({
p1Location: firstResponse.data,
p2Location: secondResponse.data,
route: thirdResponse.data,
});
}
