MiniBlink的作者是 龍泉寺掃地僧 miniblink是什么？ (抄了一下 龍泉寺掃地僧 寫的簡(jiǎn)潔)Miniblink是一個(gè)全新的、追求極致小巧的瀏覽器內(nèi)核項(xiàng)目， 為什么要做miniblink？市面上作為嵌入的組件的可用的瀏覽器內(nèi)核，不外乎這幾個(gè)：webkit、cef、nwjs、electron。 cef：優(yōu)點(diǎn)是由于集成的chromium內(nèi)核，所以對(duì)H5支持的很全，同時(shí)因?yàn)槭褂玫娜艘捕?，各種教程、示例，資源很多。但缺點(diǎn)很明顯，太大了。最新的cef已經(jīng)夸張到了100多M，還要帶一堆的文件。同時(shí)新的cef已經(jīng)不支持xp了（chromium對(duì)應(yīng)版本是M49）。而且由于是多進(jìn)程架構(gòu)，對(duì)資源的消耗也很夸張。如果只是想做個(gè)小軟件，一坨文件需要帶上、超大的安裝包，顯然不能忍受。 nwjs，或者最近大火的electron：和cef內(nèi)核類似，都是chromium內(nèi)核。缺點(diǎn)和cef一模一樣。優(yōu)點(diǎn)是由于可以使用nodejs的資源，同時(shí)又自帶了各種api的綁定，所以可以用的周邊資源非常豐富；而基于js的開發(fā)方案，使得前端很容易上手。所以最近N多項(xiàng)目都是基于nwjs或electron來實(shí)現(xiàn)。例如vscode，atom等等。 原版webkit：現(xiàn)在官網(wǎng)還在更新windows port，但顯然漫不在心，而且最新的webkit也很大了，超過20幾M。最關(guān)鍵的是，周邊資源很少，幾乎沒人再基于webkit來做開發(fā)。同時(shí)由于windows版的saferi已經(jīng)停止開發(fā)了，所以用webkit就用不了他的dev tools了。這是個(gè)大遺憾。 WKE：這是個(gè)很老的webkit內(nèi)核的裁剪版了。小是小，但bug太多了。 那么關(guān)鍵點(diǎn)來了，使用miniblink有啥好處呢？？ 首先，miniblink對(duì)大小要求非常嚴(yán)格。原版chromium、blink里對(duì)排版渲染沒啥大用的如音視頻全都被砍了，只專注于網(wǎng)頁的排版和渲染。甚至為了裁剪大小，我不惜使用vc6的crt來跑mininblink。這個(gè)也算前無古人后無來者了。 其次，miniblink緊跟最新chromium，這意味著chromium相關(guān)的資源都可以利用。在未來的規(guī)劃里，我是打算把electron的接口也加上的，這樣可以無縫替換electron。使用miniblink的話，開發(fā)調(diào)試時(shí)用原版electron，發(fā)布的時(shí)候再替換掉那些dll，直接可以無縫切換，非常方便。 miniblink如何裁剪到這么小？這個(gè)比較復(fù)雜了。主要就是把blink從chromium抽離了出來，同時(shí)補(bǔ)上了cc層（硬件渲染層）。現(xiàn)在的blink，已經(jīng)不是當(dāng)年的那個(gè)webkit了，渲染部分全走cc層，復(fù)雜無比。我這大半年都在重寫他那個(gè)蛋疼又復(fù)雜的cc層。 和webkit比，miniblink架構(gòu)有什么優(yōu)勢(shì)現(xiàn)在的webkit版本，已經(jīng)比miniblink落后太多了。blink一直在加入各種極富創(chuàng)造力和想象力的功能、組件。例如，blink早就加入多線程解析html token、blink gc回收器、多線程錄制回放渲染機(jī)制。這些能讓blink的解析渲染速度極大提升。下一次，我會(huì)先開源出blink gc組件，這東西很有意思，在c++里硬是搞出了一個(gè)垃圾回收機(jī)制，能讓你像寫java一樣寫c++。 miniblink 開源地址：https://github.com/weolar/miniblink49 我們可以通過miniblink做桌面應(yīng)用的UI，超小的附加dll，壓縮之后大約5M，比起Cefsharp 小太多了。VSCode也是用 Electron 網(wǎng)頁開發(fā)的 Html開發(fā)UI和WPF對(duì)比有什么優(yōu)勢(shì)？ 1、 Html 前端資源豐富，各種框架 2、 會(huì)Html的人比會(huì)WPF的人多太多了，入門簡(jiǎn)單 3、.Net2.0照樣可以用 4、網(wǎng)站和桌面程序界面可以統(tǒng)一，甚至大部分前端代碼復(fù)用 資源消耗方面，和WPF差不多，畢竟瀏覽器也是內(nèi)存消耗大戶 不過對(duì)比electron 這種純 Html CSS + js的，我更喜歡 用C# 代替JS 做業(yè)務(wù)邏輯，我感覺JS寫大項(xiàng)目 代碼比較亂，維護(hù)比C#麻煩。所以 JS做前端輔助比較合適，業(yè)務(wù)邏輯用C#實(shí)現(xiàn) 接下來，我寫個(gè)簡(jiǎn)單的MiniBlink封裝案例！更多功能你們可以自行封裝 或者 看看 DSkin 采用 PInvoke 和Winform封裝方式，MiniBlink對(duì)外提供的接口主要在 wke.h ，miniblink 的dll可以通過GitHub源碼編譯出來。具體封裝規(guī)則，你們可以百度查查看 1 using System;
