    CordovaSQLitePlugin

    Cordova SQLite plugin with a straightforward low-level API.

    Why this module?

    To use a SQLite database from a Cordova app, there is the cordova-sqlite-storage plugin. It is a good choice if you like the WebSQL API but in case you don't, there are not many options.

    What's wrong with the WebSQL API? It is simply the worst API ever created throughout the history of computing. Jokes aside, in my opinion there is something fundamentally wrong: when we are in the middle of a transaction, there is no way to run something asynchronously.

    This is why I created this module, I extracted all the good part (the native code) from cordova-sqlite-storage and replaced the less good part (the JavaScript code implementing the WebSQL API) by a much simpler low-level API.

    You can use this module directly but I would rather recommend to go with the AnySQL module which is a slightly higher level API.

    Installation

    With Cordova CLI tool:

    cordova plugin add cordova-sqlite-plugin
    

    Usage

    var SQLite = window.cordova.require('cordova-sqlite-plugin.SQLite');
     
    var sqlite = new SQLite('example');
     
    sqlite.open(function(err) {
      if (err) throw err;
      sqlite.query('SELECT ? + ? AS solution', [2, 3], function(err, res) {
        if (err) throw err;
        console.log(res.rows[0].solution);
      });
    });

    sqlite.query(sql, [values], callback)

    Query the SQLite database.

    sqlite.query('SELECT ? + ? AS solution', [2, 3], function(err, res) {
      if (err) throw err;
      console.log(res.rows[0].solution); // => 5
    });
