Dexie.js can be consumed as a module. But let's skip that for now and just show the simplest possible setup. You will just need a text editor and a web browser.

Hello World

  1. Copy this code to and save as 'foo.html'

    <html>
    <head>
        <!-- Include Dexie -->
        <script src="https://npmcdn.com/dexie@latest/dist/dexie.js"></script>

        <script>
            //
            // Define your database
            //
            var db = new Dexie("friends-database");
            db.version(1).stores({
                friends: 'name,shoeSize',
                // ...add more stores (tables) here...
            });

            //
            // Open it
            //
            db.open().catch(function (e) {
                alert ("Open failed: " + e);
            });

            //
            // Put some data into it
            //
            db.friends.put({name: "Nicolas", shoeSize: 8}).then (function(){
                //
                // Then when data is stored, read from it
                //
                return db.friends.get('Nicolas');
            }).then(function (friend) {
                //
                // Display the result
                //
                alert ("Nicolas has shoe size " + friend.shoeSize);
            }).catch(function(error) {
               //
               // Finally don't forget to catch any error
               // that could have happened anywhere in the
               // code blocks above.
               //
               alert ("Ooops: " + error);
            });
        </script>
    </head>
</html>

  2. Open the file in Chrome, Opera or Firefox. If you need to test on IE, Edge or Safari, make sure to serve the page over http or https

  3. An alert box sais "Nicolas has shoe size 8".

That's all.
