本文是使用了Electron.js 构建一个 Pc端 的 “每日一文”
不把UI都复刻过来,只是把功能相应地实现一下。
DEMO介绍
应用跟手机端的“每日一文”差不多,其实这APP也是用了它的API接口
实现了的功能:
2.1 打开程序自动获取一篇文章,以及获取到其作者信息(信息来源于百度百科)
2.2 可以保存喜欢的文章到本地(/saveArticles)
2.3 可以手动获取随机一篇文章未完成 :
长按保存按钮进行文章另存为的操作
效果图
实现
用到的轮子有:
因为就一个单页面应用,我也就不把style另外拎出来了(虽然不利于后期重构和维护),但对于一个一两百行的小DEMO而言,我就懒一点了。
为了能看清楚代码结构,我就把index.html部分抽出来贴吧:
