miniblink是什么? (抄了一下 龙泉寺扫地僧 写的简洁)
Miniblink是一个全新的、追求极致小巧的浏览器内核项目,
其基于chromium最新版内核,去除了chromium所有多余的部件,只保留最基本的排版引擎blink。Miniblink保持了10M左右的极简大小,是所有同类产品最小的体积,同时支持windows xp、npapi。为什么要做miniblink?
市面上作为嵌入的组件的可用的浏览器内核,不外乎这几个:webkit、cef、nwjs、electron。
cef:优点是由于集成的chromium内核,所以对H5支持的很全,同时因为使用的人也多,各种教程、示例,资源很多。但缺点很明显,太大了。最新的cef已经夸张到了100多M,还要带一堆的文件。同时新的cef已经不支持xp了(chromium对应版本是M49)。而且由于是多进程架构,对资源的消耗也很夸张。如果只是想做个小软件,一坨文件需要带上、超大的安装包,显然不能忍受。
nwjs,或者最近大火的electron:和cef内核类似,都是chromium内核。缺点和cef一模一样。优点是由于可以使用nodejs的资源,同时又自带了各种api的绑定,所以可以用的周边资源非常丰富;而基于js的开发方案,使得前端很容易上手。所以最近N多项目都是基于nwjs或electron来实现。例如vscode,atom等等。
原版webkit:现在官网还在更新windows port,但显然漫不在心,而且最新的webkit也很大了,超过20几M。最关键的是,周边资源很少,几乎没人再基于webkit来做开发。同时由于windows版的saferi已经停止开发了,所以用webkit就用不了他的dev tools了。这是个大遗憾。
WKE:这是个很老的webkit内核的裁剪版了。小是小,但bug太多了。
那么关键点来了,使用miniblink有啥好处呢??
首先,miniblink对大小要求非常严格。原版chromium、blink里对排版渲染没啥大用的如音视频全都被砍了,只专注于网页的排版和渲染。甚至为了裁剪大小,我不惜使用vc6的crt来跑mininblink。这个也算前无古人后无来者了。
其次,miniblink紧跟最新chromium,这意味着chromium相关的资源都可以利用。在未来的规划里,我是打算把electron的接口也加上的,这样可以无缝替换electron。使用miniblink的话,开发调试时用原版electron,发布的时候再替换掉那些dll,直接可以无缝切换,非常方便。
miniblink如何裁剪到这么小?
这个比较复杂了。主要就是把blink从chromium抽离了出来,同时补上了cc层(硬件渲染层)。现在的blink,已经不是当年的那个webkit了,渲染部分全走cc层,复杂无比。我这大半年都在重写他那个蛋疼又复杂的cc层。
和webkit比,miniblink架构有什么优势
现在的webkit版本,已经比miniblink落后太多了。blink一直在加入各种极富创造力和想象力的功能、组件。例如,blink早就加入多线程解析html token、blink gc回收器、多线程录制回放渲染机制。这些能让blink的解析渲染速度极大提升。下一次,我会先开源出blink gc组件,这东西很有意思,在c++里硬是搞出了一个垃圾回收机制,能让你像写java一样写c++。

我们可以通过miniblink做桌面应用的UI,超小的附加dll,压缩之后大约5M,比起Cefsharp 小太多了。VSCode也是用 Electron 网页开发的
Html开发UI和WPF对比有什么优势?
1、 Html 前端资源丰富,各种框架
2、 会Html的人比会WPF的人多太多了,入门简单
3、.Net2.0照样可以用
4、网站和桌面程序界面可以统一,甚至大部分前端代码复用
资源消耗方面,和WPF差不多,毕竟浏览器也是内存消耗大户
不过对比electron 这种纯 Html CSS + js的,我更喜欢 用C# 代替JS 做业务逻辑,我感觉JS写大项目 代码比较乱,维护比C#麻烦。所以 JS做前端辅助比较合适,业务逻辑用C#实现
接下来,我写个简单的MiniBlink封装案例!更多功能你们可以自行封装 或者 看看
采用 PInvoke 和Winform封装方式,MiniBlink对外提供的接口主要在 wke.h ,miniblink 的dll可以通过GitHub源码编译出来。具体封装规则,你们可以百度查查看
