Build DB abstraction layer for mysql and postgres as a local module in node.js using async/await promises

Hi, I would like to have a simple local module that abstracts basic DB I/O functions for mysql and postgres using the async/await promises pattern. Later this is extended to DB drivers for Oracle and other RDBMS. Delivery expectations: - [login to view URL] for the mysql implementation - [login to view URL] for the postgres implementation - [login to view URL] with any required db configs to be included in the db-*.js files - use connection pools, prepared statements and error handling - [login to view URL] with simple GET route (/test) for me to test that your implementation is working Intended usage: [login to view URL] // implements DB abstraction layer for mysql (later the same pattern is used for Oracle, Postgres, Microsoft SQL etc. // export for usage as a local module // take all db connection and other configurations from [login to view URL] file [login to view URL] { // contains connection details, e.g. "host" : "localhost", ... } usage in [login to view URL]: const db = require("mysql-db"); let con = [login to view URL](); //create connection pool and get a connection let query = "select * from table where field=?or other_field=?;"; // or other query for insert/update/delete let params = ["condition1", "condition2"]; // array of values for query // must use prepared statements let result = await [login to view URL](query, params); let result = await [login to view URL](query, params); let result = await [login to view URL](query, params); let last_id = [login to view URL]; let result = await [login to view URL](query, params); // error handling
