Sencha recently released Ext JS 5, and we have received lots of positive feedback from our customers and community. Beyond the addition of tablet support, MVVM and many awesome new features, we really wanted to prove that Ext JS 5 is engineered for performance and is the best choice for building enterprise web applications.
Performance is something that every developer should care about — and Sencha has spent considerable effort over the past several years helping our customers understand best practices and performance tweaks to fine tune their applications. You can find dozens of presentations on performance from SenchaCon and our webinar series on Vimeo, as well as many articles right here on our blog.
But performance is absolutely critical in the enterprise, where data sets can reach into the hundreds of thousands of records and projects have very tight timelines. The Ext JS grid has long been the best choice for displaying enterprise data sets, and Ext JS 5 delivers performance improvements and many new features like Grid widgets and improved charting. Combined with our Class System and support for both MVC and MVVM architectures, building high performance enterprise applications has never been easier!
Goals for Ext JS 5
When we first began planning for Ext JS 5, our team discussed three overarching goals for the framework:
- Ext JS 5 should be Engineered for business applications, achieving top performance and scaling with the largest apps and development teams.
- Ext JS 5 should increase Productivity by supporting our customers' needs, offering highly customizable widgets and predictable software delivery.
- Ext JS 5 should be Evolutionary by enhancing framework agility, adapting best practices, and maintaining both backward and forward compatibility.
In short, enterprise applications were a top priority for Ext JS 5. With more than 60% of the Fortune 100 using Sencha frameworks, it's clear that Ext JS has experienced immense success - and Ext JS 5 continues to deliver.
