                      QUESTION

                      Why on printing I get value of null from API call in Loop

                      Asked 2022-Apr-16 at 03:06

                      COIN LIST is an array of crypto coins(["BTCUSDT",...]). I try to get the price using getPriceAction and RSI from getRSI and these two functions are working when I try to console DATA. But when I try to print the response after the completion of the loop. It prints the empty array and the length is 0 of this array. I want to store the DATA object (consisting of SYMBOL, closing price and RSI) as an element in the response array

                       import { COIN_LIST } from "./COIN_LIST.js";
                          import { getPriceAction } from "./PRICE_ACTION.js";
                          import { getRSI } from "./RSI.js";
                      
                      async function main() {
                        try {
                          let response = await [];
                          await COIN_LIST.forEach((element, i) => {
                            setTimeout(() => {
                              let data = { symbol: element };
                              getPriceAction(element, "4h").then((res) => {
                                data.closingPrice = res;
                                getRSI(res).then((res) => {
                                  data.RSI = res.reverse();
                                  data.closingPrice = data.closingPrice.reverse();
                                  response.push(data);
                                  console.log(data)
                                });
                              });
                            }, i * 1000);
                          });
                          console.log(response);
                        } catch (error) {
                          console.log(error.message);
                        }
                      }
                      main();

                      After the completion of the loop, the promises didn't get resolved yet, that's why it print an empty array. One way to achieve what you need is using await for(...), or wait for all promises to be resolved, and then print the results.

                      import { COIN_LIST } from "./COIN_LIST.js";
                      import { getPriceAction } from "./PRICE_ACTION.js";
                      import { getRSI } from "./RSI.js";
                      
                      async function main() {
                        try {
                          let response = []; //---> don't need that `await`
                          const promises = []; //---> array of promises
                          COIN_LIST.forEach((element, i) => {
                            setTimeout(() => {
                              let data = { symbol: element };
                              const promise = getPriceAction(element, "4h").then((res) => {
                                data.closingPrice = res;
                                getRSI(res).then((res) => {
                                  data.RSI = res.reverse();
                                  data.closingPrice = data.closingPrice.reverse();
                                  response.push(data);
                                  console.log(data)
                                });
                              });
                              promises.push(promise) //---> save the reference to a promise
                            }, i * 1000);
                          });
                          await Promise.all(promises) //---> await for all promises to be resolved, then print the result
                          console.log(response);
                        } catch (error) {
                          console.log(error.message);
                        }
                      }

                      This project requires a few jar files that are not included in the GitHub repository. Follow the steps below to obtain these jars: gcm-server.jar. Open Android SDK Manager and choose Extras > Google Cloud Messaging for Android Library. This creates a gcm directory under YOUR_ANDROID_SDK_ROOT/extras/google/ containing "gcm-server/dist" subdirectory which has gcm-server.jar file. Download google-gson-2.1-release.zip and extract the zip file, and you have "google-gson-2.1" directory which has gson-2.1.jar file. Download json-simple.1.1.1.jar file. Download log4j-1.2.17.jar file. Download JavaPNS-2.2.jar file. Download bcprov-jdk15on-146.jar file. The downloaded jar file is signed. Execute the following command to unsign this jar file: zip -d bcprov-jdk15on-146.jar META-INF/MANIFEST.MF
                      Copy all the jars obtained in step 1 above to war/WEB-INF/lib subdirectory.
                      Import the project into Eclipse (File->Import->General->Existing Projects into Workspace and select the directory where you have unzipped the downloaded project). If you see any build errors they will be resolved after you follow the remaining steps.
                      Configure "Griddler - App Engine" project, by selecting Properties from the context menu in the Package Explorer. Select Google -> App Engine and make sure "Use App Engine" is selected and the selected App Engine SDK version is 1.8.1 or newer. As Application ID enter the Project ID that you created in step 1.
                      Obtain APNS p12 certificate for the bundle ID that you entered in step 7. Copy the p12 file to the src package in Eclipse. You can skip this step if you don't want to use iOS client.
                      Edit Configuration.java in com.google.cloud.solutions.sampleapps.griddler.backend.api package and update the following constants: String WEB_CLIENT_ID = "Your Web Client ID"; // Use the Client ID created in step 5 above. String ANDROID_CLIENT_ID = "Your Android Client ID"; // Use the Client ID created in step 6 above. String IOS_CLIENT_ID = "Your iOS Client ID"; // Use the Client ID created in step 7 above. String CLOUD_MESSAGING_API_KEY = "Your Simple API Access key for server apps"; // Use the API key created in step 8 above. String APNS_CERTIFICATE_FILE = "YouriOSPushNoficicationCertificate.p12"; // The certificate file name described in step 13 above. String APNS_CERTIFICATE_PASSWORD = "YouriOSPushNoficicationCertificatePassword"; // The password for the certificate described in step 13 above.
                      In the Package Explorer, select "Griddler - App Engine" project and from the context menu select Google -> Generate Cloud Endpoint Client Library.
                      In the Package Explorer, select "Griddler - App Engine" project and from the context menu select Google -> Deploy to App Engine. This will upload Griddler mobile game backend to the cloud.
                      Upload sample game board definitions to your mobile game backend. Make sure that you have Python App Engine SDK installed. Navigate to "data" subdirectory and execute the following command (Make sure to replace YOUR_PROJECT_ID with your actual project id created in step 1): appcfg.py upload_data --config_file=config.yml --filename=boards.csv --url=http://YOUR_PROJECT_ID.appspot.com/remote_api --kind=Board
                      Now you are ready to configure and run Griddler Android client and/or Griddler iOS client
