Angular 入门教程系列:37:使用ng-alain快速开发

ng-alain在ng-zorro-antd上再封一程,可以更快加速开发速度,目前在github上已经超过1800个star。这篇文章来简单看一下如何使用。

创建应用框架

因为alain缺省使用使用less作为样式设定,在创建骨架时需要指定style为less方式。使用ng new alaindemo –skip-install –style less进行创建。

下载依赖

可以使用yarn或者npm install进行依赖包的下载

启动&确认

使用ng serve启动应用,会报出各种错误,官方称使用npm即可,并给了yarn和npm的plugin的使用,确认之后还是将Less的版本,另外碰到问题之后反复npm install->删除node_modules也未曾成功。所以使用了如下官网不建议的方式: git clone -> npm install -> ng serve

git clone

liumiaocn:WebstormProjects liumiao$ git clone https://github.com/cipchk/ng-alain alain

确认

这就是ng-alain的目前版本的确认页面
这里写图片描述
最近的一些例子中用的布局根alain很像的例子,也只是很像而已,用非常少的代码,模拟一下而已。在入门的时候,不考虑其他因素,仅先考虑功能性,在会用之后,在比较一下alain的代码,相信每个人都会有自己的体会。

总结

尝试了一下将git clone方式生成的node_modules直接给ng add 方式生成的项目使用,结果发现可以启动,但是css显示仍然有问题,但至少已经能够启动,有兴趣的朋友可以比较两个package.json的差别,相信至少能够推到ng serve启动的步骤上,不过花时间在这上面确实有点浪费,后续版本相信稳定之后将会是一行ng add可以将其引入的方式,clone下来自己增删改也是一个使用的方式。ng-zorro-antd只是一个前端的组件库,ng-alain真正意义上接近一个前端框架的概念,自带很多可以进行开发的类似半成品的sample,有一定能力的开发者可以考虑在此基础上进行修改。
