How to solve the problem of using particles special effects in vue3

vue-particles uses the require API internally. Vue3 has completely abandoned require and embraced commonJSes6. If one place is changed, problems will occur in other places.

The first step: introduce particles.js

npm i particles.js
or
yarn add particles.js

The second step: find particles.js in node_modules

Get it out:

After getting it out, you can use npm uninstall particles.js to remove the dependency

Step 3: Create particles directory under project components

After putting the found particles.js in, create index.vue and particles.json in its same-level directory:

Step 4: Write the following content in index.vue

<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>

Step 5: Write the following content in particles.json

{
    "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
}

Step 6: Modify particles.js

1. Replace lines 1416 - 1427 with:

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. Add the last line:

export default window.particlesJS

Step 7: Introduce the index here .vue

<template>
  <div>
    <particles></particles>
  </div>
</template>
