Grand Central Records (GCR)

A promise-based Node ORM/ActiveRecord library that can connect to MySQL, Postgres, and SQLite3. Allows chainable, raw or queueable queries.

Getting started

### new GCR(connection, [table], [options])

var GCR = require('grand-central-records');

var Model = new GCR({
    adapter: "mysql",
    host: "localhost",
    database: "test",
    username: "admin",
    password: "admin"
}, "users");

Model.find(8).then(function(users) {
    console.log(users[0].name);
}).catch(console.error);

Model.select(["name","address"]).where({admin: true})
.then(function(result) {
    result.forEach(function(user) { ... });
});

Creating a new instance of the GCR object creates a connection to a new database.

• connection object — Database connection parameters.
  • adapter — mysql/MySQL, postgresql/postgres/pg, sqlite3/sqlite
  • host, database, username, password — connection parameters
• table string — An optional table name if only a single table is being queried.
• options object — Options to pass to the model.
  • verbose boolean function — Turning verbose on will log all queries to the console. false by default. If a function is provided, it will be used to log all outputs.
  • idAttribute string — The name of the unique ID attribute field (defaults to 'id').
  • (see Models)

### model(table, [options])

• table string — The name of the table the model is associated with.
• options json — See above.

Multiple models can also be created from the same database.

var GCR = require('grand-central-records');

var db = new GCR({
    adapter: "mysql",
    host: "localhost",
    database: "test",
    username: "admin",
    password: "admin"
}, { verbose: true });

var User = db.model("users"),
    Project = db.model("projects");
