给Next.js加个antd用的Nprogress进度条

前言

用的别人的Nprogress的样式，这里也算拿来记录一下，很方便的工具，没什么依赖就能和其他框架继承。

用法

yarn add nprogress

新建一个文件，如nprogress.css:

#nprogress {
  pointer-events: none;
}

#nprogress .bar {
  background: #29d;

  position: fixed;
  z-index: 1031;
  top: 0;
  left: 0;

  width: 100%;
  height: 2px;
}

/* Fancy blur effect */
#nprogress .peg {
  display: block;
  position: absolute;
  right: 0px;
  width: 100px;
  height: 100%;
  box-shadow: 0 0 10px #29d, 0 0 5px #29d;
  opacity: 1;

  -webkit-transform: rotate(3deg) translate(0px, -4px);
  -ms-transform: rotate(3deg) translate(0px, -4px);
  transform: rotate(3deg) translate(0px, -4px);
}

/* Remove these to get rid of the spinner */
#nprogress .spinner {
  display: block;
  position: fixed;
  z-index: 1031;
  top: 15px;
  right: 15px;
}

#nprogress .spinner-icon {
  width: 18px;
  height: 18px;
  box-sizing: border-box;

  border: solid 2px transparent;
  border-top-color: #29d;
  border-left-color: #29d;
  border-radius: 50%;

  -webkit-animation: nprogress-spinner 400ms linear infinite;
  animation: nprogress-spinner 400ms linear infinite;
}

.nprogress-custom-parent {
  overflow: hidden;
  position: relative;
}

.nprogress-custom-parent #nprogress .spinner,
.nprogress-custom-parent #nprogress .bar {
  position: absolute;
}

@-webkit-keyframes nprogress-spinner {
  0% {
    -webkit-transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
  }
}
@keyframes nprogress-spinner {
  0% {
    transform: rotate(0deg);
  }
  100% {
    transform: rotate(360deg);
  }
}

剩下的就是在_app.js中加入：

import Router from "next/router";
import NProgress from "nprogress";
import "../utils/np.css";

Router.onRouteChangeStart = url => {
  NProgress.start();
};
Router.onRouteChangeComplete = () => NProgress.done();
Router.onRouteChangeError = () => NProgress.done();

这样在路由切换时就能看到效果。

通过antd的官网就能看到类似的效果。
