ActorDB connector for Node.js

Installation

The recommended way to get started using the ActorDB connector for Node.js is by using the npm (Node Package Manager) to install the dependency.

npm install actordb

ActorDBClient Interface

Create a single connection to database

var ActorDB = require('actordb');
var adbc = ActorDB.connectSingle({ host:'localhost', port:33306, username:"<username>", password:"<password>" });
adbc.connect().then(function(db){
    // connected code ...
  });

Close a single connection

adbc.close();

Create a pool of connections to database

var ActorDB = require('actordb');
var adbc_pool = ActorDB.connectionPool({ host:'localhost', port:33306, username:"<username>", password:"<username>" }, { pool_size : 5 });
adbc_pool.connect().then(function(){
  // fetch a ActorDBClient instance
  adbc = adbc_pool.db();
  // execute actions like on a single connection
  adbc.exec_sql(...)
});  

Close a pool of connections

adbc_pool.close();

Executing SQL statement

adbc.exec_sql("ACTOR user(myid1); SELECT * FROM contact;").then(function(result){
  // work with the result set
  console.log(result);
});

Executing a single SQL statement with parameters

client1.exec_single_param("myuserid", "user", "INSERT INTO contact (contact_id, contact_name) VALUES (?1,?2);", [ 'CREATE' ], [ ["contact_id", "contact_name"] ] ).then(function(result) {
  // work with the result set
  console.log(result);
}).catch(function(err){
  // handle error
  console.log(err);
});

Fetching Unique ID

client1.uniqid().then(function(uniqid){
  console.log("uniqid:");
  console.log(uniqid);
});

Fetching DB generated salt

client1.salt().then(function(salt){
  console.log("salt:");
  console.log(salt);
});

Executing a single SQL statement

client1.exec_single("myuserid123", "user","INSERT INTO contact (contact_id, contact_name) VALUES ('2131244','scott');",[ 'CREATE' ]).then(function(result){
  console.log("insert2 query result:");
  console.log(result);
}).catch(function(err){
  console.log("insert2 query error:");
  console.log(err);
});

Fetching all Actor types

adbc.actor_types().then(function(types){
  // work with actor types
  console.log(types);
});

Fetching all Tables for an Actor Type

adbc.actor_tables("actor_type").then(function(actor_tables){
  // work with table list
  console.log(actor_tables);
});

Fetching all columns for a Table within an Actor Type

client1.actor_columns("user", "contact").then(function(column_list){
  // work with column list
  console.log(column_list);
});

Example usage

Connecting through a single connection and performing a query

var ActorDB = require('actordb');
var client = ActorDB.connectSingle({ host:'localhost', port:33306, username:"actordb_username", password:"actordb_password" });

client.connect(function(err, db) {
    client.exec_sql("ACTOR user(userid1); SELECT * FROM data;", function(err,data){
    client.close();
    console.log(data);
    });  
});

Setting up a pool of connections and performing a query

var ActorDB = require('actordb');
var pool = ActorDB.connectionPool({ host:'localhost', port:33306, username:"actordb_username", password:"actordb_password" }, { pool_size : 3 });

pool.connect().then(function(){
  pool.db().exec_sql("ACTOR user(userid1); SELET * FROM data;").then(function(r){
    console.log(r);
    pool.close();
  });
});
