海外TECH	DEV Community	Building a real-time bidding system with Socket.io and React Native 🤩	https://dev.to/novu/building-a-real-time-bidding-system-with-socketio-and-react-native-1cj5	Building a real time bidding system with Socket io and React Native What is this article about Goin Once Goin Twice Sold to the lady with the red dress You have probably heard that many times in movies or public auctions We can also find some online platforms such as eBay where you can bid on a product and get counterbids from other bidders Today we are going to build a mobile app with React Native and Socket io eBay style To use online bidding We must stick to the same principles We must give our bidder information as soon as a new bid comes In this article you ll learn how to build a bidding application that allows users to add auction items and update the bid prices in real time using React Native and Socket io Novu the first open source notification architectureJust a quick background about us Novu is the first open source notification infrastructure We basically help to manage all the product notifications It can be In App the bell icon like you have in Facebook Websockets Emails SMSs and so on I would be super happy if you could give us a star And let me also know in the comments ️ React Native is an open source React framework that enables us to create native applications for both IOS and Android with JavaScript code Basic knowledge of React Native is required to understand this tutorial What is Socket io Socket io is a popular JavaScript library that allows us to create real time bi directional communication between web browsers and a Node js server It is a highly performant and reliable library designed to process a large volume of data with minimal delay It follows the WebSocket protocol and provides better functionalities such as fallback to HTTP long polling or automatic reconnection which enables us to build efficient real time applications How to connect React Native to a Socket io serverHere you ll learn how to connect the bidding application to a Socket io server In this guide I ll use Expo the tool that provides an easier way of building React Native applications Installing ExpoExpo saves us from the complex configurations required to create a native application with the React Native CLI making it the easiest and fastest way to build and publish React Native apps Ensure you have the Expo CLI  Node js and Git installed on your computer Then create the project folder and an Expo React Native app by running the code below mkdir bidding appcd bidding appexpo init appExpo allows us to create native applications using the Managed or Bare Workflow We ll use the blank Managed Workflow in this tutorial Choose a template › Use arrow keys Return to submit Managed workflow ❯blank a minimal app as clean as an empty canvas blank TypeScript same as blank but with TypeScript configuration tabs TypeScript several example screens and tabs using react navigation and TypeScript Bare workflow minimal bare and minimal just the essentials to get you startedInstall Socket io Client API to the React Native app cd appexpo install socket io clientCreate a socket js within a utils folder mkdir utilstouch socket jsThen copy the code below into the socket js file import io from socket io client const socket io connect http localhost export default socket The code snippet above creates a real time connection to the server hosted at that URL We ll create the server in the upcoming section Create a styles js file within the utils folder and copy the code below into the file It contains all the styling for the chat application import StyleSheet from react native export const styles StyleSheet create addProductContainer flex

 React Navigation allows us to navigate from one screen to another within a React Native application npm install react navigation nativenpx expo install react native screens react native safe area context Setting up the Node js serverHere I will guide you through creating the Socket io Node js server for real time communication with the React Native application Create a server folder within the project folder cd bidding appmkdir serverNavigate into the server folder and create a package json file cd server amp npm init yInstall Express js CORS Nodemon and Socket io Server API npm install express cors nodemon socket ioExpress js is a fast minimalist framework that provides several features for building web applications in Node js  CORS is a Node js package that allows communication between different domains Nodemon is a Node js tool that automatically restarts the server after detecting file changes and Socket io allows us to configure a real time connection on the server Create an index js file the entry point to the Node js server touch index jsSet up a simple Node js server using Express js The code snippet below returns a JSON object when you visit the http localhost api in your browser index jsconst express require express const app express const PORT app use express urlencoded extended true app use express json app get api req res gt res json message Hello world app listen PORT gt console log Server listening on PORT Next add Socket io to the project to create a real time connection Before the app get block copy the code below New imports const socketIO require socket io http cors origin http localhost Add this before the app get blocksocketIO on connection socket gt console log socket id user just connected socket on disconnect gt socket disconnect console log A user disconnected From the code snippet above the socket io connection function establishes a connection with the React app creates a unique ID for each socket and logs the ID to the console whenever you refresh the app When you refresh or close the app the socket fires the disconnect event showing that a user has disconnected from the socket Configure Nodemon by adding the start command to the list of scripts in the package json file The code snippet below starts the server using Nodemon In server package json scripts test echo Error no test specified amp amp exit start nodemon index js You can now run the server with Nodemon by using the command below npm start Building the app user interfaceHere we ll create the user interface for the bidding application to enable users to sign in put items up for auction and bid for products The user interface is divided into three screens the Login the Bid Page and the Add Product screens First let s set up React Navigation Create a screens folder within the app folder add the Login BidPage and AddProduct components and render a Hello World text within them mkdir screenscd screenstouch Login js BidPage js AddProduct jsCopy the
