vue3使用particles粒子特效的问题怎么解决

vue-particles 内部用了 require 这个api，vue3已经全面弃用了require，去拥抱 commonJSes6 了，改动了一个地方，其他地方也会出问题。

第一步：引入 particles.js

npm i particles.js

or

yarn add particles.js

第二步：找到 node_modules 内的 particles.js

把它弄出来 ：

弄出来后可以用 npm uninstall particles.js 将依赖去除

第三步：项目 components 下创建 particles 目录

将找到的 particles.js 放进去后，在其同级目录创建 index.vue 与 particles.json：

第四步：index.vue 写入以下内容

<template>

  <div class="particles-js-box">

    <div id="particles-js"></div>

  </div>

</template>

<script>

/* eslint-disable */

import particlesJs from "./particles.js";

import particlesConfig from "./particles.json";

export default {

  data() {

    return {};

  },

  mounted() {

    this.init();

  },

  methods: {

    init() {

      particlesJS("particles-js", particlesConfig);

      document.body.style.overflow = "hidden";

    },

  },

};

</script>

<style scoped>

.particles-js-box {

  position: fixed;

  width: 100%;

  height: 100%;

  top: 0;

  left: 0;

  z-index: 1;

}

#particles-js {

  background-color: #2d3a4b;

  width: 100%;

  height: 100%;

}

</style>

第五步：particles.json 写入以下内容

{

    "particles": {

        "number": {

            "value": 60,

            "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": 0.5,

            "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": 0.4,

            "width": 1

        },

        "move": {

            "enable": true,

            "speed": 4,

            "direction": "none",

            "random": false,

            "straight": false,

            "out_mode": "out",

            "bounce": false,

            "attract": {

                "enable": false,

                "rotateX": 100,

                "rotateY": 1200

            }

        }

    },

    "interactivity": {

        "detect_on": "Window",

        "events": {

            "onhover": {

                "enable": true,

                "mode": "grab"

            },

            "onclick": {

                "enable": true,

                "mode": "push"

            },

            "resize": true

        },

        "modes": {

            "grab": {

                "distance": 140,

                "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": true

}

第六步：修改 particles.js

1、1416行 - 1427行 替换为：

Object.deepExtend = function f(destination, source) {

  for (var property in source) {

    if (source[property] && source[property].constructor &&

     source[property].constructor === Object) {

      destination[property] = destination[property] || {};

      f(destination[property], source[property])

    } else {

      destination[property] = source[property];

    }

  }

  return destination;

};

2、最后一行添加：

export default window.particlesJS

第七步：引入这里的index.vue

<template>

  <div>

    <particles></particles>

  </div>

</template>

<script>

import Particles from '@/components/particles/index.vue'

export default {

  components: {

    "particles":Particles

  }

};

</script>
