Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

smooth-output

使输出更加平滑~(常用于处理SSE文本输出场景)

SmoothOutput 是一个用于以受控速度平滑输出字符串的工具类。它支持使用 requestAnimationFrame (RAF) 或定时器进行输出动画。

NPM 版本 NPM 下载量

安装

npm install smooth-output

特性

  • 自动根据输入速度调整输出速度。
  • 支持随机暂停输出,模拟人类打字和思考。
  • 不依赖于特定框架(如 React、Vue)。
  • 支持 Node.js 和浏览器环境。
  • 易于使用。

API

构造函数

new SmoothOutput(output: (output: string) => void, options?: {
  fps?: number;
  useRAF?: boolean;
  minStepTime?: number;
  maxStepTime?: number;
  randomStepTimeMaxDiff?: number;
  inputType?: PutType;
  outputType?: PutType;
});

参数

  • output (函数): 每一步接收输出字符串的回调函数。
  • fps (数字, 可选): 每秒帧数,控制输出的更新频率。默认值为 40。
  • useRAF (布尔值, 可选): 是否使用 requestAnimationFrame 进行输出更新。默认值为 true。
  • minStepTime (数字, 可选): 处理输入的最小时间(毫秒)。默认值为 100。
  • maxStepTime (数字, 可选): 处理输入的最大时间(毫秒)。默认值为 2000。
  • randomStepTimeMaxDiff (数字, 可选): 处理输入时间的最大随机减少值(用于随机暂停输出以模拟人类打字和思考)(毫秒)。默认值为 200。
  • inputType (PutType, 可选): 输入类型,可以是 "full" 或 "slice"。默认值为 "slice"。
  • outputType (PutType, 可选): 输出类型,可以是 "full" 或 "slice"。默认值为 "full"。

方法

  • input(str: string): void

    输入一个字符串并根据配置的节奏参数平滑输出。

  • async beDisposed(): Promise<void>

    标记实例为已处理。通常不需要调用此函数,但调用此函数可以获得一个输出结束的 Promise。

基本用法

import SmoothOutput from 'smooth-output';

const so = new SmoothOutput((output) => {
  console.log('output', output);
});
so.input('Hello, world! ');
setTimeout(() => {
  so.input('This is a test.');
}, 1000);

// 控制台输出可能是:

// output Hell
// output Hello, w
// ...
// output Hello, world! 

// output Hello, world! T
// output Hello, world! Th
// output Hello, world! Thi
// ...
// output Hello, world! This is a test.
