AlaSQL supports plugins but the feature is not yet documented.

Currently AlaSQL has one official plugins:

• ECHO (working demo)

include plugins directly:

    <script src="alasql.min.js"></script>
    <script src="alasql-echo.js"></script>

And REQUIRE the plugin

    alasql('REQUIRE ECHO');
    var res = alasql('ECHO 123');  // logs 123 to the console
