Editing the config.js file with database credentials

As we can see, the sequelize command creates many files, including a database configuration file. This file has a sample configuration for application databases.

1. Open config/config.json and edit the development tag with our database details, as the following highlighted code:

         { 
           "development": { 
           "username": "root", "password": "", "database": "mvc_mysql_app", "host": "127.0.0.1", "port": "3306", "dialect": "mysql" 
           }, 
           "test": { 
               "username": "root", 
               "password": null, 
               "database": "database_test", 
               "host": "127.0.0.1", 
               "dialect": "mysql" 
           }, 
           "production": { 
               "username": "root", 
               "password": null, 
               "database": "database_production", 
               "host": "127.0.0.1", 
               "dialect": "mysql" 
           } 
         } 
   

Tip

Note that I'm using user root with no password to connect with my database, if you have a different user or are using a different password, replace the previous code with your own credentials.
