Prompt Title: deploy node js graphql server on back4app

Deploying a Node.js GraphQL server on Back4App involves the following steps:

1. Create a new app on Back4App:

   • Log in to your Back4App account and click the "Create New App" button.
   • Give your app a name and select a server location.

2. Set up your Node.js environment:

   • Install Node.js on your local machine if you haven't already.
   • Create a new Node.js project and add the necessary dependencies for your GraphQL server (e.g., express, graphql, apollo-server-express).
   • Write your GraphQL schema and resolvers.

3. Configure your Back4App app:

   • Open your app on Back4App and go to the "Server Settings" tab.
   • Click the "Deploy" button and select "Custom Server".
   • Choose a server location and copy the server URL.

4. Deploy your GraphQL server:

   • Open your terminal and navigate to your Node.js project directory.
   • Install the parse-server and parse-dashboard packages:

     Copy code
     npm install parse-server parse-dashboard
     

   • Create a new index.js file and add the following code:

     javascriptCopy code
     const express = require('express');
     const { ApolloServer, gql } = require('apollo-server-express');
     
     const typeDefs = gql`
       type Query {
         hello: String
       }
     `;
     
     const resolvers = {
       Query: {
         hello: () => 'Hello world!'
       }
     };
     
     const server = new ApolloServer({ typeDefs, resolvers });
     
     const app = express();
     server.applyMiddleware({ app });
     
     app.listen(process.env.PORT || 4000, () => {
       console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`);
     });
     

   • Replace the typeDefs and resolvers with your own schema and resolvers.
   • Add the following lines to the beginning of your index.js file to initialize Parse Server and Parse Dashboard:

     javascriptCopy code
     const ParseServer = require('parse-server').ParseServer;
     const ParseDashboard = require('parse-dashboard');
     
     const parseServer = new ParseServer({
       databaseURI: 'mongodb://user:[email protected]:port/yourdbname',
       appId: 'yourAppId',
       masterKey: 'yourMasterKey',
       serverURL: 'https://yourappname.back4app.io/parse',
       liveQuery: {
         classNames: [] // List of classes to support for query subscriptions
       }
     });
     
     const parseDashboard = new ParseDashboard({
       apps: [{
         serverURL: 'https://yourappname.back4app.io/parse',
         appId: 'yourAppId',
         masterKey: 'yourMasterKey',
         appName: 'Your App Name'
       }]
     });
     

   • Replace the values in the databaseURI, appId, masterKey, and serverURL fields with your own Back4App app information.
   • Run the following command to start your GraphQL server:

     Copy code
     node index.js
     

5. Test your GraphQL server:

   • Open your Back4App app dashboard and go to the "Logs" tab to check for any errors.
   • Use a GraphQL client like GraphiQL or Apollo Studio to test your GraphQL API by sending queries and mutations to your server endpoint (e.g., https://yourappname.back4app.io/graphql).
