| For years OpenWrt was using [[LuCI]], a web user interface written in [[http://en.wikipedia.org/wiki/Lua_(programming_language)|Lua]]. It required several Lua extensions (like ''ubus'', ''luci.model.uci'', ''nixio.fs'', etc.) to access system info and settings. Unfortunately this solution appeared to be quite resource consuming and didn't work well on devices with slow CPU and little amount of RAM. | For years OpenWrt was using [[LuCI]], a web user interface written in [[http://en.wikipedia.org/wiki/Lua_(programming_language)|Lua]].

| This lead to developing LuCI2, a new web interface with a different architecture. It doesn't use Lua anymore, but static HTML page and [[http://en.wikipedia.org/wiki/XMLHttpRequest|JavaScript XHR]] method. It means building HTML pages is done on client (browser) side offloading OpenWrt device. To access any kind of system data [[ubus]] is used (with the help of [[ubus#access_to_ubus_over_http|uhttpd-mod-ubus]] to provide HTTP based API). | This led to developing LuCI2, a new web interface with a different architecture.

| ==== How to test ==== | |
| Code is being developed here https://github.com/jow-/luci-ng | |
| |
| FIXME: As of March 2019 - The 'feed' method described here no longer works. | |
| |
| Add new feed into [[https://openwrt.org/docs/guide-developer/feeds|feeds.conf]] : | |
| <code> | |
| src-git luci2 https://github.com/jow-/luci-ng.git | |
| </code> | |
| |
| Install luci2 packages: | |
| <code>./scripts/feeds update | |
| ./scripts/feeds install luci2 | |
| </code> | |
| |
| Select package Luci2 in menuconfig and compile new image. | |
