ES6 Promise-based interface to the sqlite3 module.
npm install sqlite-asyncsqlite-async module exports the Database class. Each method works the same as the original sqlite3 API. Instead of callbacks, each method returns a promise. The prepare method returns a Statement instance that also wraps all of the original statement methods into methods that return a promise.
javascript
import { Database } from 'sqlite-async':
Database.open('test.db')
.then(db => {
...
})
.catch(err => {
...
}):
`
The test/sqlite-async-test.js file provides examples.
API
$3
Static getter that returns the version number of the node-sqlite3 package currently being used by this module.
$3
Static method that instantiates a new Database object and calls Database#open(filename, mode). Returns a promise that is resolved with the Database instance.
$3
Opens the database with the same arguments as the sqlite3 Database constructor. Returns a promise that is resolved with the Database instance.
$3
Closes the database and returns a promise. If the optional provider function (fn) is specified, it is called as fn(db) before the database is closed. This function must return a promise. The database is closed regardless of whether the promise returned by the optional provider function is resolved or rejected. If the returned promise is rejected, then the close method itself will return a rejected promise with the error from the promise returned by the provider function.
$3
Equivalent to the sqlite3 Database#run method. Returns a promise that is resolved with the this parameter from the sqlite3 callback function.
$3
Equivalent to the sqlite3 Database#get method. Returns a promise that is resolved with the row.
$3
Equivalent to the sqlite3 Database#all method. Returns a promise that is resolved with the rows.
$3
Equivalent to the sqlite3 Database#each method. The per-row callback function is requied. Returns a promise that is resolved with the Database instance.
$3
Equivalent to the sqlite3 Database#exec method. Returns a promise that is resolved with the Database instance.
$3
The transaction method allows a function returning a promise to be wrapped in a transaction. The function is passed the Database instance as its parameter. Returns a promise that is resolved with the function's promise value.
`javascript
db.transaction((db) => {
return Promise.all([db.run('INSERT INTO test VALUES (2, "two")'), db.run('INSERT INTO test VALUES (2, "three")')]);
});
`
$3
Equivalent to the sqlite3 Database#prepare method. Returns a promise that is resolved with the Statement instance.
$3
Equivalent to the sqlite3 Statement#bind method. Returns a promise that is resolved with the Statement instance.
$3
Equivalent to the sqlite3 Statement#reset method. Returns a promise that is resolved with the Statement instance.
$3
Equivalent to the sqlite3 Statement#finalize method. Returns a promise that is resolved with no value because the statement can no longer be used.
$3
Equivalent to the sqlite3 Statement#run method. Returns a promise that is resolved with the this parameter from the sqlite3 callback function.
$3
Equivalent to the sqlite3 Statement#get method. Returns a promise that is resolved with the row.
$3
Equivalent to the sqlite3 Statement#all method. Returns a promise that is resolved with the rows.
$3
Equivalent to the sqlite3 Statement#each` method. The per-row callback function is requied. Returns a promise that is resolved with the Statement instance.
