Text Search in Node.JS Streams

Circle CI Code Coverage 0 dependencies install size Language grade: JavaScript

This micro-library (no dependencies) searches for occurrences of a given search term (string or Regex) in a Node.js stream, i.e. anything that emits data events with Buffers or strings.

import { TextStreamSearch } from "text-stream-search"

const streamSearch = new TextStreamSearch(myStream)

// wait until myStream contains "hello"
await streamSearch.waitForText("hello")

// capture data from the stream
const matchText = await streamSearch.waitForRegex("listening at port \\d+.")
// matchingText contains something like "listening at port 3000."

// access the captured stream content
const text = streamSearch.fullText()
