一、介绍 👵 👵

TypeIt是一个JavaScript库，用于创建简单而流畅的打字效果和动画效果。它可以用于网页开发中的很多场景，例如创建动态文字效果、制作页面过渡动画、增强用户体验等。

我们还可以利用它进行一些后端日志的回显，如果某个进程后端实时或者定时返回结果，前端进行一个动画打字的回显功能，一方面可以让我们的页面更丰富，另一方面可以给客户一个很好的体验。

配置项说明  👇 👇 👇

二、安装依赖 🏃 🏃

yarn add typeit

三、使用 👲 👲

1、官网示例 👇 👇 👇

new TypeIt("#hero", {speed: 50,startDelay: 900,
}).type("the mot versti", { delay: 100 }).move(-8, { delay: 100 }).type("s", { delay: 400 }).move(null, { to: "START", instant: true, delay: 300 }).move(1, { delay: 200 }).delete(1).type("T", { delay: 225 }).pause(200).move(2, { instant: true }).pause(200).move(5, { instant: true }).move(5, { delay: 200 }).type("a", { delay: 350 }).move(null, { to: "END" }).type("le typing utlity").move(-4, { delay: 150 }).type("i").move(null, { to: "END" }).type(' on the <span class="place">internet</span>', { delay: 400 }).delete(".place", { delay: 800, instant: true }).type('<em><strong class="font-semibold">planet.</strong></em>', {speed: 100,}).go();

2、效果 👇 👇 👇

四、模拟异步请求 不断追加内容 🙇 🙇

1、API 👇 👇 👇

这里的话我用延迟器模拟数据在不断的更新，比如每次返回的数据都是最新的，我只需要追加在后面即可，那根据官方的demo，只需要使用type和flush。

2、完整代码 👇 👇 👇

<template><div style="text-align: center;font-size: 30px;font-weight: bold;">不断叠加</div><div id="element"></div>
</template><script lang="ts">
import TypeIt from "typeit";
export default defineComponent({setup() {const total = ref<number>(10)const instance: any = ref()const generatorContent = (i: number) => {const timer = setInterval(() => {if (i >= total.value) {clearInterval(timer);instance.value.type(`<br>11:23:56 [vite] hmr update /src/views/home.vue (X${i})`).flush();} else {instance.value.type(`<br>11:23:56 [vite] hmr update /src/views/home.vue (X${i})`).flush();}i++;}, 500);instance.value.go()}onMounted(() => {instance.value = new (TypeIt as any)('#element', {speed: 10, //打字的速度,每步之间以毫秒为单位测量。lifeLike: false, // 使打字速度不规则，就好像真人在做一样。html: true})// instance.value.reset();generatorContent(0)})return {}}
})
</script><style>
#element {height: calc(100% - 40px);width: 100%;background: #1e1f22;display: flex;flex-direction: column;align-items: center;justify-content: center;color: #d5dadd;
}
</style>

五、模拟异步请求 不断更新内容 👴 👴

这里的话我用延迟器模拟数据在不断的更新，但是每次返回的数据都是追加过的内容，需要把新的数据内容提取出来追加在现有的数据上，我这里只是一个demo，自己根据自己的情况去提取，然后api的话和上面一样的。

<template><div style="text-align: center;font-size: 30px;font-weight: bold;">不断追加更新</div><div id="element"></div>
</template><script lang="ts">
import TypeIt from "typeit";
export default defineComponent({setup() {const contentList = ref<string[]>(['11:23:56 [vite] hmr update /src/views/home.vue (X0)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X6)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X6)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X7)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X8)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X6)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X7)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X8)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X9)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X6)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X7)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X8)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X9)','11:23:56 [vite] hmr update /src/views/home.vue (X0)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X1)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X2)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X3)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X4)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X5)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X6)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X7)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X8)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X9)<br>' +'11:23:56 [vite] hmr update /src/views/home.vue (X10)'])const total = ref<number>(10)const instance: any = ref()const generatorContent = (i: number) => {const timer = setInterval(() => {const content = i === 0 ? contentList.value[i] : contentList.value[i].split(contentList.value[i - 1])[1]if (i >= total.value) {clearInterval(timer);instance.value.type(content).flush();} else {instance.value.type(content).flush();}i++;}, 500);instance.value.go()}onMounted(() => {instance.value = new (TypeIt as any)('#element', {speed: 10, //打字的速度,每步之间以毫秒为单位测量。lifeLike: false, // 使打字速度不规则，就好像真人在做一样。html: true})generatorContent(0)})return {}}

不管是哪一种方式，体现出来的动画都是一样的。
