Setup Your Own Environment

1. Install JOR to your node project:

    $ npm install json-on-relations --save

2. Create the database in MySQL:

   After you install MySQL, copy file "node_modules/json-on-relations/MDB.sql" to your sql console and execute. The script will create database "MDB" which contains all the tables and the data.

   Please also create a DB user 'nodejs' with password 'nodejs'. By default, Portal uses credential 'nodejs/nodejs' to connect MySql at port 3306. You can of course change the default settings. Please refer the next step.

3. In your NodeJS project:

   Copy the folder node_modules/json-on-relations/dist and its belongings to the project root.

   Create server.js in the project root with following codes:

   const express = require('express');
   const app = express();
   
   // We don't want to serve sessions for static resources
   const path = require('path');
   app.use(express.static(path.join(__dirname, 'dist/jor')));
   
   const cors = require('cors'); // Allow cross site requests
   app.use(cors());
   
   app.use(require('body-parser').json());
   const compress = require('compression');
   app.use(compress());
   
   // Routing
   const routes = require('json-on-relations').Routes;
   app.use('/', routes);
   // The index page as an entry point
   app.route('*').get( (req, res) => {   
     res.sendFile(path.join(__dirname, '../dist/jor/index.html'));
   });
   
   process.on('SIGINT',function(){
     console.log("Closing.....");
     process.exit()
   });
   
   const entityDB = require('json-on-relations').EntityDB;
   entityDB.setConnPool('mysql', { // Set the connection pool to your mysql DB.
                                   // Currently, we only support mysql.
                                   connectionLimit : 10,
                                   host: 'localhost',  // To be replaced by your DB host
                                   user: 'nodejs',     // To be replaced by your own DB user
                                   password: 'nodejs', // To be replaced by your own DB password
                                   database: 'MDB',
                                   createDatabaseTable: true,
                                   multipleStatements: true,
                                   dateStrings: true,
                                   port: 3306           // replaced by your DB port.
                                 });
   app.listen(3000, () => console.log('Example app listening on port 3000!'));

   You should also install the involved packages: express, path, cors, body-parse, and compression.

4. Start the server:

    $ node server.js
