    <p>I have developed a generic sync solution called <strong>WebSqlSync</strong>. </p> <p>It's not dependant of any framework. It's available here : <a href="https://github.com/orbitaloop/WebSqlSync" rel="noreferrer">https://github.com/orbitaloop/WebSqlSync</a></p> <p>Extract of the README file :</p> <h1>WebSqlSync</h1> <p>Automatically synchronize a local WebSql database (SQLite in the navigator) to a server. (2 way sync : client &lt;-> server)</p> <p>Very easy to integrate to your existing app and very easy to use (2 functions to call : initSync and syncNow)</p> <h1>Usage</h1> <h2>Initialize</h2> <p>You need to initialize the lib (at each startup for example).</p> <p>It will automatically create 2 tables (if they don't already exists, one to store all the new or modified elements (table new_elem) and one to store the date of the last sync (table sync_info). It will also create SQLite triggers in order to watch the INSERT or UPDATE on the tables you want to synchronize (to automatically insert the modified elements in the new_elem table):</p> <pre><code>DBSYNC.initSync(TABLES_TO_SYNC, webSqlDb, sync_info, 'http://www.myserver.com', callBackEndInit); </code></pre> <p>Where TABLES_TO_SYNC is the list of table that you want to sync with the server, ex :</p> <pre><code>TABLES_TO_SYNC = [ {tableName : 'table1', idName : 'the_id'}, {tableName : 'table2'} //if idName not specified, it will assume that it's "id" ]; </code></pre> <h2>Synchronize</h2> <p>To start the synchronization, you need to call the syncNow function. You can call it every X seconds, or after some changes for example :</p> <pre><code>DBSYNC.syncNow(callBackSyncProgress, function(result) { if (result.syncOK === true) { //Synchronized successfully } }); </code></pre> <p>And that's all you need to do on the client. On the server side, you will need to code your own solution (but it's not complicated). And there are some example inPHP &amp; Java. Again, contributions are welcome.</p>

    1. COHow well would you say this have worked for you, summarizing it one year later? I'm looking for a good client-side DB that works for browsers and mobile units.

    2. COWebSQLSync is working very well with more than 25 apps in production (iOS and Android). WebSQL is really great and fast. It's working on iOS, Android, Blackberry (the latest version I think) and of course chrome and safari. But it's not working on IE and firefox, because the API has been depreciated by W3C..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
