海外TECH	DEV Community	How to Setup Firebase For Flutter - Android and IOS	https://dev.to/nibukdk/how-to-setup-firebase-for-flutter-android-and-ios-3jca	How to Setup Firebase For Flutter Android and IOS IntroHello and welcome I am Nibesh Khadka from Khadka s Coding Lounge This is a short article on how to set up a Firebase project on Flutter Feel free to skip through the TOC if you feel like it Setting UpBefore we set up firebase let s create a Flutter project first Open the terminal and on the directory of your choice let s create a flutter project Note I am using Linux OS flutter create flutter firebase connectioncd flutter firebase connection open in vs codecode Create A Firebase ProjectPlease create a Firebase project on firebase console If you have never created a Firebase project then follow the instructions from this code lab by google Install Firebase CLIWe ll rely on FlutterFire package for our development Configuring the FlutterFire package can be done with FlutterFire CLI But FlutterFire CLI relies on the Firebase CLI Follow the instruction there to install and login into the firebase account No need to initialize firebase now we will do it later on after FlutterFire CLI configurations Install DependenciesAfter the firebase CLI installation before we link our project to the firebase project we ll install some dependencies On your terminal Root of the flutter project Firebase coreflutter pub add firebase core Firebase Authflutter pub add firebase auth Firebase Firestoreflutter pub add cloud firestore Firebase Cloud Functionsflutter pub add cloud functions Firebase Storageflutter pub add firebase storageWe ve installed Firebase Core Firebase Auth Firebase Cloud Functions and Firebase Storage packages for flutter Install and Configure FlutterFire CLILet s install and configure flutter CLI on the terminal Install Firebase CLIdart pub global activate flutterfire cli On the root of your project configur cliflutterfire configureDuring the configuration process You ll be asked to choose the right project from the list if there are multiple You ll also be asked to choose apps for the project Chose only android and ios You can select deselect with the space bar You ll be asked to provide the bundle id for IOS I just gave the same one as android com example app Now we re done with flutter fire installation and configurations and next we need to initialize it Firebase InitializationOn the main dart file of the project let s initialize firebase Import import package firebase core firebase core dart import firebase options dart import package flutter material dart void main async concrete binding for applications based on the Widgets framewor WidgetsFlutterBinding ensureInitialized Initialize Firebase await Firebase initializeApp options DefaultFirebaseOptions currentPlatform runApp const MyApp Set Up Firebase Backend CloudIf you ll be writing a lot of backend code you should separate the flutter frontend and firebase backend side for both security and clean code So let s set up firebase separately for both cloud and emulators Reminder Before we start configuration make sure to create a Firestore database on test mode from the firebase console of the project you ve created Otherwise you ll get an error during the process telling you there s no database created On the root of your projectfirebase initYou ll be asked to choose from different Firebase products Choose four Firestore Firebase Storage Cloud Functions and Emulators Next you have to choose the Firebase project or create one Since we ve already created one chose the right project from the existing ones Just press enter on all the file options provided there Select the language to use for firebase functions I ll select JS Select y for both linter and installations During the process you ll be prompted to Emulators settings Here please select four products Authentication Firestore Storage and Functions Emulators Just press enter to select the default ports Enter Y to enable emulator UI Press enter for the rest Now we ve set up all the necessities Wait there s still more we still haven t linked the flutter project to Firebase Emulator Suite Connect Firebase Emulator Suite to Flutter Project To connect to the emulator we once again need to make some changes to the main dart file Import required dependencies if you haven t already import dart io show Platform Its required for emulator import package cloud firestore cloud firestore dart import package cloud functions cloud functions dart import package firebase auth firebase auth dart import package firebase storage firebase storage dart Create a global boolean useEmulator Outside of any class or methods before main const bool useEmulator true Create a function that ll connect to the emulator with the required settings Outside of main preferably at the end of the file Settings for firebase emulator connectionFuture connectToEmulator async Provide url to the emulator localhost might not work on android emulator final host Platform isAndroid localhost Provide port for all the local emulator prodcuts const authPort const firestorePort const functionsPort const storagePort Just to make sure we re running locally print I am running on emulator Instruct all the relevant firebase products to use the firebase emulator await FirebaseAuth instance useAuthEmulator host authPort FirebaseFirestore instance useFirestoreEmulator host firestorePort FirebaseFunctions instance useFunctionsEmulator host functionsPort FirebaseStorage instance useStorageEmulator host storagePort Let s go through the vitals When running on an android emulator it s actually not localhost So it can give you errors so check the platform and provide the right URL Each firebase product will run on its port So provide the right port You can find the port for all products in the firebase json file Instruct all the products to use Firebase Emulator if it s running Now we need to call this function on main method after you initialize firebase Set app to run on firebase emulator if useEmulator await connectToEmulator Final CodeWe re all set to use the emulator now The final form of our main dart is import package flutter material dart import package firebase core firebase core dart import firebase options dart import dart io show Platform Its required for emulatorimport package cloud firestore cloud firestore dart import package cloud functions cloud functions dart import package firebase auth firebase auth dart import package firebase storage firebase storage dart Outside of any class or methods before main const bool useEmulator true void main async concrete binding for applications based on the Widgets framewor WidgetsFlutterBinding ensureInitialized Initialize Firebase await Firebase initializeApp options DefaultFirebaseOptions currentPlatform Set app to run on firebase emulator if useEmulator await connectToEmulator runApp const MyApp class MyApp extends StatelessWidget const MyApp Key key super key key This widget is the root of your application override Widget build BuildContext context return MaterialApp title Flutter Demo theme ThemeData primarySwatch Colors blue home MyHomePage class MyHomePage extends StatelessWidget int counter override Widget build BuildContext context return Scaffold appBar AppBar title const Text App bar body const Center child Text Flutter Fireabse Connection App Settings for firebase emulator connectionFuture connectToEmulator async Provide url to the emulator localhost might not work on android emulator final host Platform isAndroid localhost Provide port for all the local emulator prodcuts const authPort const firestorePort const functionsPort const storagePort Just to make sure we re running locally print I am running on emulator Instruct all the relevant firebase products to use the firebase emulator await FirebaseAuth instance useAuthEmulator host authPort FirebaseFirestore instance useFirestoreEmulator host firestorePort FirebaseFunctions instance useFunctionsEmulator host functionsPort FirebaseStorage instance useStorageEmulator host storagePort Run the firebase emulator On terminalfirebase emulators startWhen you run your android emulator you should see the I am running on emulator message emulator should be running Error Could not start Firestore Emulator port taken At some point when we accidentally forget to close the port we ll get an error that the port is already taken To fix that we have to kill the port Provide the port that has been given in an error message like npx kill port Now that the active port has been terminated you can start the emulator again which will look like the image below SummaryIn this very short series we moved on to connect our app to the Firebase project Let s retrace our steps we Created Firebase Project amp Firestore DB Installed Firebase CLI amp FlutterFire CLIInstalled Firestore Functions Storage and Authentication packages Then connected these Firebase products to the cloud Firebase project on Firebase Init During the initialization we also installed Firebase Emulator and did all the configuration Wrote a simple and easy function that handles Local Emulator Connection for us Now know how to solve the port unavailable error issue Show SupportThis is it we re done with the connection Now you can proceed with your development I hope everything went well for you This is Nibesh Khadka from Khadka s Coding Lounge Make sure to show support by liking sharing commenting and subscribing to future blogs	2022-04-04

海外TECH	DEV Community	Implementing Distributed Tracing in a Java application	https://dev.to/signoz/implementing-distributed-tracing-in-a-java-application-29jf	Implementing Distributed Tracing in a Java applicationMonitoring and troubleshooting distributed systems like those built with microservices is challenging Traditional monitoring tools struggle with distributed systems as they were made for a single component Distributed tracing solves this problem by tracking a transaction across components In this article we will implement distributed tracing for a Java Spring Boot application with three microservices To implement distributed tracing we will be using open source solutions SigNoz and OpenTelemetry so you can easily follow the tutorial We will learn more about SigNoz and OpenTelemetry but before that let s have a brief overview of distributed tracing What is Distributed Tracing In a microservices architecture a user request travels through hundreds even thousands of services before serving the user what they need Engineering teams often responsible for maintaining single services have no visibility over how the system performs as a whole Read our complete guide on Distributed TracingDistributed tracing gives insights into how a particular service performs as part of the whole in a distributed software system It involves passing a trace context with each user request which is then passed across hosts services and protocols to track the user request The technique enables the reconstruction of the whole path of the request which is called a trace A trace allows application owners to see how their entire system processed a request and identify improvement areas SigNoz and OpenTelemetryOpenTelemetry is a vendor agnostic set of tools APIs and SDKs used to instrument applications to create and manage telemetry data logs metrics and traces It aims to make telemetry data logs metrics and traces a built in feature of cloud native software applications It is a project under CNCF with huge community backing OpenTelemetry provides the instrumentation layer to generate and export your telemetry data to a backend Then you need to choose a backend tool that will provide the data storage and visualization for your telemetry data That s where SigNoz comes into the picture SigNoz is a full stack open source APM tool that provides metrics monitoring and distributed tracing We will demonstrate implementing distributed tracing in a Java application in two sections Running a sample Java application with OpenTelemetryVisualizing traces data with SigNoz dashboards Running a sample Spring Boot Java application with OpenTelemetryThe sample Spring Boot Java application will have three microservices and a service registry user serviceorders servicepayment servicediscovery service eureka server service registry Here s the architecture of the sample Java application along with OpenTelemetry and SigNoz Application architecture along with SigNoz and OpenTelemetry OTel Collector Pre requisitesJava or newerMySql SigNozMaven Installing SigNozSigNoz can be installed on macOS or Linux computers in just three steps by using a simple install script The install script automatically installs Docker Engine on Linux However on macOS you must manually install Docker Engine before running the install script git clone b main https github com SigNoz signoz gitcd signoz deploy install shYou can visit our documentation for instructions on how to install SigNoz using Docker Swarm and Helm Charts When you are done installing SigNoz you can access the UI at http localhost SigNoz dashboard It shows services from a sample app that comes bundled with the application Installing MySqlDownload MySQL community version from here based on your operating system Once installation is complete run the below commands to create a database for our sample nodejs app ➜ mysql u rootmysql gt create database signoz mysql gt use signoz Installing

Servercd discovery servermvn clean install Dmaven test skipdocker build t discovery service docker run d name discovery service p discovery service You can go to http localhost and make sure your discover service registry with Eureka server is up and running Eureka server is up and runningSetting up Opentelemetry agentFor instrumenting Java applications OpenTelemetry has a very handy Java JAR agent that can be attached to any Java application The JAR agent can detect a number of popular libraries and frameworks and instrument it right out of the box You don t need to add any code for that Download the latest version of the Java JAR agent and copy jar agent file in your application code We have placed the agent under the folder named agents Placed OpenTelemetry Java Jar agent under a folder named agentsSetting up SigNoz as the OpenTelemetry backendTo set up OpenTelemetry to collect and export telemetry data you need to specify OTLP OpenTelemetry Protocol endpoint It consists of the IP of the machine where SigNoz is installed and the port number at which SigNoz listens OTLP endpoint for SigNoz lt IP of the machine gt If you have installed SigNoz on your local machine then your endpoint is Create a start sh script with below environment variables and move it to scripts folder Notice that we have updated the OTLP endpoint under Dotel exporter otlp traces endpoint http

services check if the tables ORDERS and USERS are created using the commands below mysql gt use signoz mysql gt show tables Checking creation of tables after running microservices Visualizing traces data with SigNoz dashboardsTo visualize the traces data with SigNoz we first need to generate some user data by interacting with the spring boot application Generating user data by interacting with the sample appYou need to generate some user data to see how it appears in the SigNoz dashboard The sample application comes with an UI to interact with the app Use the below command in the root folder to launch the UI npm install g serveserve l uRunning sample app UIUse the buttons to interact with the app and generate some data For example click Create User button to create a new user in the MySQL db Create a new userNow go to SigNoz dashboard you will notice the list of service names that we configured user serviceorder servicepayment serviceMicroservices in our Java app being monitored in the SigNoz dashboardYou can play around with the dashboard to see what data is captured Below is a handy guide on how to use the SigNoz dashboard to see the captured data How to use SigNoz dashboard to analyze tracesThe traces tab of the SigNoz dashboard provides powerful filters to analyze the traces data You can use a number of filters to see traces data across many dimensions For example See the count of requests by service and HTTP Status codeUse advanced filters to see count of requests by service and HTTP status codeRun aggregates on your tracing dataYou can run aggregates like avg max min th percentile th percentile on your tracing data to get analyze performance issues in your application Run aggregates using the dropdown on your traces data quicklyGet more granular details by grouping traces dataYou can also see these aggregates in more granular detail by grouping them by service name operation HTTP URL HTTP method etc Group aggregates across a list of dimensionsIdentify latency issues with Flamegraphs and Gantt chartsYou can inspect each span in the table with Flamegraphs and Gantt charts to see a complete breakdown of the request Establishing a sequential flow of the user request along with info on time taken by each part of the request can help identify latency issues quickly Let s see how it works in the case of our sample Spring Boot app Go to operation filter on the left navigation and apply two filters payment transfer id id amount amount and service name payment service Click on the single event listed in the table as shown below Use filters to inspect spans that you want to investigate furtherYou will be able to see the Flamegraph of the selected span which shows how the request traveled between the payment service and the user service You can also use the Gantt chart to analyze each event in detail Flamegraph and Gantt chart for the selected event showing payment service traces with HTTP semanticsDatabases traces which show semantics related to mysql db and query detailsSigNoz also provides a detailed view of common semantic conventions like HTTP network and other attributes The end to end tracing of user requests can help you to identify latency issues quickly ConclusionDistributed tracing is a powerful and critical toolkit for developers creating applications based on microservices architecture For Java Spring Boot applications based on microservices architecture distributed tracing can enable a central overview of how requests are performing across microservices This lets application owners reconstruct the whole path of the request and see how individual components performed as part of the entire user request OpenTelemetry and SigNoz provide a great open source solution to implement distributed tracing for your applications You can try out SigNoz by visiting its GitHub repo If you have any questions or need any help in setting things up join our slack community and ping us in
