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 🙏

v1.0.28

Published

实时将 Markdown 文本流智能切分为可朗读句子。

Readme

介绍

实时将 Markdown 文本流智能切分为可朗读句子。

  • ✅ 流式处理:逐片段接收,边收边切
  • ✅ 智能分段:按中英文句末标点切分,自动过滤 Markdown 与 emoji
  • ✅ 歧义缓存:小数/句号、未闭合链接尾部缓存,等待后续片段确认

安装

# pnpm
pnpm add @minto-ai/text-stream-slicer

快速开始

import TextStreamSlicer from '@minto-ai/text-stream-slicer'

const slicer = new TextStreamSlicer()

// 流式片段(如 SSE / WebSocket)
console.log(slicer.processText('你要')) // []
console.log(slicer.processText('抱我吗?')) // ['你要抱我吗?']

// 输入结束收尾输出
console.log(slicer.processText('', true))

API

实例方法

TextStreamSlicer#processText

处理输入的文本片段,结合内部缓存智能切分为可朗读句子。

processText(text: string, includeRemaining?: boolean): string[]

参数

  1. text (string) 当前收到的文本片段(允许为空字符串)
  2. [includeRemaining=false] (boolean) 是否收尾输出;true 时将剩余缓存一并输出

返回值

  • (string[]) 可朗读的句子数组;无完整句子时返回空数组

高级示例

  • 流式 SSE 场景
import TextStreamSlicer from '@minto-ai/text-stream-slicer'

const slicer = new TextStreamSlicer()
const evtSource = new EventSource('/chat-sse')

evtSource.onmessage = (event) => {
  const sentences = slicer.processText(event.data)
  sentences.forEach(s => speak(s))
}

evtSource.onerror = () => {
  const tail = slicer.processText('', true)
  tail.forEach(s => speak(s))
}
  • 小数 / 句号歧义
import TextStreamSlicer from '@minto-ai/text-stream-slicer'

const slicer = new TextStreamSlicer()
slicer.processText('停车费') // []
slicer.processText('2') // []
slicer.processText('.') // []
console.log(slicer.processText('3元。', true)) // ['停车费2.3元。']
  • Markdown 链接
import TextStreamSlicer from '@minto-ai/text-stream-slicer'

const slicer = new TextStreamSlicer()
slicer.processText('官网') // []
slicer.processText('[链接](https://xx.com)') // []
console.log(slicer.processText('已结束。', true)) // ['官网链接已结束。']
