Promiscuous MySQL

Promisucous MySQL is a promise-based MySQL client built on top of the mysql module.

Example

const database = require('promiscuous-mysql')
 
database.withConnection({
  host: 'example.org',
  user: 'bob',
  password: 'secret',
  database: 'my-database'
}, (connection) => {
  return connection.query('SELECT * FROM `items`')
})
  .then((result) => {
    console.log(result)
  })

API - Usage

database.createConnection(config) Returns: Connection

Creates a new Connection instance.

• config (Object): The connection configuration. See the mysql connection options for details.

database.withConnection(config, callback) Returns: Promise

Creates a new Connection instance, invokes the callback with the new instance, then ends the connection.

• config (Object): The connection configuration. See the mysql connection options for details.
• callback (Function: function(connection) Returns: Promise): A callback used to perform queries with the created connection. Must return a promise indicating whether the operation was successful. The value of the promise returned from the callback will become the return value for withConnection(). If there is an error creating the connection, the callback will not be invoked and the returned promise will be rejected.

database.withTransaction(config, callback) Returns: Promise

Creates a new Connection instance, starts a transaction, invokes the callback, then ends the transaction and connection.

• config (Object): The connection configuration. See the mysql connection options for details.
• callback (Function: function(connection) Returns: Promise): A callback used to perform queries within the created transaction. Must return a promise indicating whether the operation was successful. If the callback's promise is resolved, the transaction will be committed; if the callback's promise is rejected, the transaction will be rolled back. The value of the promise returned from the callback will become the return value for withTransaction(). If there is an error creating the connection, the callback will not be invoked and the returned promise will be rejected.

database.createPool(name, config) Returns: Pool

Creates a new connection pool.

• name (String): The name for the pool.
• config (Object): The connection configuration. See the mysql documentation for connection options for details.

database.withPooledConnection(name, callback) Returns: Promise

Creates a new Connection instance, invokes the callback with the new instance, then ends the connection.

• name (String): The name of the pool to use.
• callback (Function: function(connection) Returns: Promise): A callback used to perform queries with the created connection. Must return a promise indicating whether the operation was successful. The value of the promise returned from the callback will become the return value for withPooledConnection(). If there is an error creating the connection, the callback will not be invoked and the returned promise will be rejected.

database.withPooledTransaction(name, callback) Returns: Promise

Creates a new Connection instance, starts a transaction, invokes the callback, then ends the transaction and connection.

• name (String): The name for the pool.
• callback (Function: function(connection) Returns: Promise): A callback used to perform queries within the created transaction. Must return a promise indicating whether the operation was successful. If the callback's promise is resolved, the transaction will be committed; if the callback's promise is rejected, the transaction will be rolled back. The value of the promise returned from the callback will become the return value for withPooledTransaction(). If there is an error creating the connection, the callback will not be invoked and the returned promise will be rejected.

Connection#query() Returns: Promise

Performs a query using the existing connection. See the mysql documentation for performing queries. All signatures are supported, just leave out the callback.

Connection#end() Returns: Promise

Ends the connection.

Pool#end() Returns: Promise

Ends the connection pool.
