FIS vs FIS+: Understanding the Differences
FIS is a core compilation engine that defines static resource management concepts, while FIS+ builds on it to provide a full PHP‑Smarty3 solution with a complete directory structure, extra plugins for integration and security, and features like local data simulation and URL forwarding.
This article explains the differences between FIS and FIS+, two related front-end development tools. FIS is positioned as a core engine providing a compilation system and static resource management design concepts, while FIS+ extends FIS to create a complete solution for PHP+Smarty3 backend architectures.
The key differences include: FIS has no directory specifications while FIS+ provides a complete directory structure for organizing JavaScript, CSS, and modules; FIS+ includes additional plugins for PHP/Smarty3 integration and XSS protection; FIS+ implements the static resource management framework that FIS only conceptualized; and FIS+ adds local data simulation and URL forwarding capabilities beyond FIS's basic local server.
The relationship between FIS and FIS+ is compared to WebKit and Chrome, or Android and MIUI - where FIS is the engine and FIS+ is a distribution built on top of it. The article also discusses naming confusion and why the official website now promotes FIS+ as it represents the complete implementation of FIS's powerful concepts.
