var html5rocks = Asynchronous and Transactional # This sample uses a namespace to encapsulate the database logic.

It is a very high level tour of some of the features available in HTML5. The example code in this article demonstrates how to create a very simple todo list manager. By allowing developers to create applications with rich query abilities it is envisioned that a new breed of web applications will emerge that have the ability to work online and off-line. Web Databases are hosted and persisted inside a user's browser. Instead, developers are encouraged to use IndexedDB, the replacement technology. This is a recommendation for web developers to no longer use the technology as effectively the spec will receive no new updates and browser vendors aren't encouraged to support this technology. So please – PostgreSQL, MySQL, Redis, or MongoDB – At least pick one of these up.On November 18, 2010, the W3C announced that Web SQL database is a deprecated specification.

They are not great when it comes to performance-wise.(How are you going to mirror that file across all servers?) It works on a simple single-server setup but will fail horribly on distributed/cloud. It’s a great learning tool for beginners, but they are not recommended for professional use: SQLite is simple and it works out of the box without any installation. SQLITE IS NOT GOOD FOR PRODUCTION SYSTEMS So what’s sorely missing is a user login system, I will leave some links below if you want to learn more. It has zero security, and anyone can see/update the list as they see fit. Of course, nobody will put this up on the Internet as-it-is. That’s all for the tutorial, and here is a small section on some extras and links that may be useful to you. So how about deleting an item? We will do that with a small Javascript trick. (C) Pretty much the same HTML form, but this also includes name='id' to indicate updating of an item.The only part worth mentioning here is, used to separate between saving/deleting an entry. (B) Just your regular HTML form to add an item.The rest are the “to-do list” related functions.select() Another helper function to run a SELECT SQL and return the results.A helper function to run an SQL statement. It may seem intimidating to some beginners at first, but keep calm and look carefully. With the database in place, the next step is to create the to-do list library itself. Query('UPDATE todo SET txt=? WHERE id=?', ) Query('INSERT INTO todo (txt) VALUES (?)', )
