Database abstraction

Attempt to provide a unified low level interface to various databases. Currently supports:

  1. MySql
  2. PostgreSql

one need to npm install pg / mysql in order to use those implementations

Example

 $ npm install db-stuff pg
var dbStuff = require('db-stuff');
 
var config = {
    implementation: 'PostgresDatastore',
    connectionString: 'tcp://user:pass@redshift.host:5439/db'
};
 
dbStuff.create(config, function (err, datastore) {
 
    datastore.query('select * table', function(err, data) {
        console.log(err, data);
    });
    
    // with params
    datastore.query('select * table where x=$1', [1], function(err, data) {
        console.log(err, data);
    });
 
    datastore.insert('table', { a: 1, b: 2}, function (err) {
    })
 
    datastore.update('table', { a: 1, b: 3}, function (err) {
    })
 
    datastore.update('table', { a: 1, b: 3}, {id: 1, b:2 } function (err) {
        // update record where id = 1 AND b = 2
        // this simple filter only supports AND(s)
        // for more complex stuff just run query() 
    })
 
    // with params
    datastore.createQuery('select * from table where x=$1', [1], function(err, q) {
        q.on('row', function(row) {
 
        });
 
        q.on('error', function(err) {
 
        });
 
        q.on('end', function(results) {
 
        });
    });
 
    datastore.createQuery('select * from table', function(err, q) {
        ...
        ...
        ...
    });
 
 
    //reusable/batch insert command
    function cb(err) {
        console.log(err);
    }
 
    var insertCommand = datastore.newInsertCommand('table', ['fieldA', 'fieldB']);
 
    insertCommand.execute([1,2], cb);
    // raw strings - will be places directly inside VALUES (...), this is very unsafe though
    insertCommand.execute('1,2', cb);
 
    var bulkInsertCommand = datastore.newBulkInsertCommand('table', ['fieldA', 'fieldB'])
    bulkInsertCommand.execute([
        [1,2],
        [3,4],
        [5,6]
    ], cb)
});
