在vue中的使用粒子动画 particles.js

1.安装particlesJS

npm install --save particles.js

2.创建particles.json文件，设置particles的配置参数

{
    "particles": {
      "number": {
        "value": 40,
        "density": {
          "enable": true,
          "value_area": 800
        }
      },
      "color": {
        "value": "#ffffff"
      },
      "shape": {
        "type": "circle",
        "stroke": {
          "width": 0,
          "color": "#000000"
        },
        "polygon": {
          "nb_sides": 5
        },
        "image": {
          "src": "img/github.svg",
          "width": 100,
          "height": 100
        }
      },
      "opacity": {
        "value": 0.7,
        "random": false,
        "anim": {
          "enable": false,
          "speed": 1,
          "opacity_min": 0.1,
          "sync": false
        }
      },
      "size": {
        "value": 3,
        "random": true,
        "anim": {
          "enable": false,
          "speed": 40,
          "size_min": 0.1,
          "sync": false
        }
      },
      "line_linked": {
        "enable": true,
        "distance": 150,
        "color": "#ffffff",
        "opacity": 0.6,
        "width": 1
      },
      "move": {
        "enable": true,
        "speed": 6,
        "direction": "none",
        "random": false,
        "straight": false,
        "out_mode": "out",
        "bounce": false,
        "attract": {
          "enable": false,
          "rotateX": 600,
          "rotateY": 1200
        }
      }
    },
    "interactivity": {
      "detect_on": "canvas",
      "events": {
        "onhover": {
          "enable": true,
          "mode": "grab"
        },
        "onclick": {
          "enable": true,
          "mode": "push"
        },
        "resize": true
      },
      "modes": {
        "grab": {
          "distance": 200,
          "line_linked": {
            "opacity": 1
          }
        },
        "bubble": {
          "distance": 400,
          "size": 40,
          "duration": 2,
          "opacity": 8,
          "speed": 3
        },
        "repulse": {
          "distance": 200,
          "duration": 0.4
        },
        "push": {
          "particles_nb": 4
        },
        "remove": {
          "particles_nb": 2
        }
      }
    },
    "retina_detect": false
  }

3.创建styleOflogin.css文件，设置div背景颜色或图片

#particles-js{
        width: 100%;
        height: 100%;
        position: relative;
        background-color: #2b4b6b;
        background-position: 50% 50%;
        background-size: cover;
        background-repeat: no-repeat;
        margin-left: auto;
        margin-right: auto;
    }

4.引入（局部引入）

 <style scoped>
  @import "../../public/css/styleOflogin.css";
</style>
<template>
  <div style="min-height:730px; height:100px">
    <div id="particles-js"></div>
  </div>
</template>

<script>
  import particlesJs from "particles.js";
  import particlesConfig from "./particles.json";
  export default {
    data() {
      return {};
    },
    mounted() {
    	particlesJS("particles-js", particlesConfig);
    },
  };
