title: How can I perfectly work with Oracle DB in my Node.js project
body: <p>I am currently working on a web site using Angular, Node.Js, express and an Oracle database.</p>
  <p>I'm still not familiar with all this technologies and I'm doing my best! My problem is the Oracle database connection can't be exported. I searched about this and I think it's a promise thing. The only solution I found is to connect to the database every time I use a new SQL query which is impossible for me because the project is big.</p>
  <p>Is there any method I can use to make the database connection in a separate file and export it when I need it?</p>
