Wht is mySQLWrapper?

mySQLWrapper is a light module to run sql query on MySQL database. Module provide two methods getter and setter. Methods getter should use for all SELECT type statement and return selected rows. Methods setter should use for all UPDATE or INSERT type statmenet and return id of upated or insert row.

How to run SQL query

1. Add DB credential to .env (DB_SERVER, DB_NAME, DB_LOGIN, DB_PASSWORD, LOG_FILE_PATH, LOG_LEVEL, CONSOLE_LOG_PRINT)
2. Import package to your file var dbConnect = require('syncsourcewrapper');
3. Declare new class instance const dbConnect = new dbConnect.dbConnection();
4. Run your statement let statment = dbConnect.getter(sqlQuery, [queryValues]) in query you can put ? char, in places where you want to inject queryValues from array like this let statment = dbConnect.getter('SELECT ?, ? FROM products', ['id', 'product_name'])
5. Check your query status result statment.status === 500 - whoops we have some error or statment.status === 200 - every thigns goes ok
6. If you have error you can get error description like this let queryError = statment.message or go to log in LOG_FILE_PATH location
7. If everything's goes ok you can get your statement result

For getter

{status: 200, selectRows: [{selectedRowObject}...]}

For setter

{status: 200, insertRowId: insertRowId, affectedRowsNumber: affectedRowsNumber}

If you want to close connection call void close method like this dbConnect.close();
