I spent a good couple hours troubleshooting a bug where the yelp-fusion api said I was sending too many requests per second, so I finally found a way to delay each api request to make it work. Please take a look at the code and give me any tips you have. I’d like to see how this could be done in a better way if possible.

Here is my server.js where post requests come through:

  //handle post requests for getting yelp data   app.post('/post', async function(req, res) {     let yelpInData = []     let result = null;     req.body.forEach((item) => {       yelpInData.push(item);     });      result = await handleYelp(yelpInData);     //send data back to the front end     res.send(result);    });    //handle yelp api   async function handleYelp(yelpInData) {     let yelpData = [];      for (let i = 0, len = yelpInData.length; i < len; i++) {       let result = await searchPlace(yelpInData[i]);       yelpData.push(result);     }     //  console.log(yelpData);     return yelpData;    }    function searchPlace(city) {     //console.log(city)     return new Promise((resolve) => {       setTimeout(() => {         let coords = city.coords.lat + "," + city.coords.lng;         let name = city.name;          client.search({term: name, location: coords}).then(response => {            //name, img url, review count, rating, price, location.display address, is closed,phone           resolve({             name: response.jsonBody.businesses[0].name,             img: response.jsonBody.businesses[0].image_url,             hours: response.jsonBody.businesses[0].is_closed,             revcount: response.jsonBody.businesses[0].review_count,             rating: response.jsonBody.businesses[0].rating,             price: response.jsonBody.businesses[0].price,             location: response.jsonBody.businesses[0].location.display_address.toString(),             phone: response.jsonBody.businesses[0].display_phone,             url: response.jsonBody.businesses[0].url           });          }).catch(e => {           console.log(e);         });       }, 100);     })   } 

Is setTimeout a good idea for delaying the api requests to yelp or is there a different way to delay? Here is the git repo if you want to run the web app: https://github.com/capozzic1/knockout_map
