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 🙏

emptyLinesRemover

Streaming Empty Lines Remover that aims for high speed of remove as well as compatibility with the all streaming modules in Node.js.

npm install emptyLinesRemover

emptyLinesRemover can transform javascript streams (work with buffer) and if data is strings (text, csv or other) (utf8) will be remove all empty lines or empty lines contains spaces. Support text, csv and other formats, created in Linux, Window and Mac systemes.

Usage

Simply instantiate txt and pump a text file to it and get the new file without unnecessary empty lines.

Let's say that you have a text file file1.txt like this:

London is a capital

of Great Britain

You can parse it like this:

const EmptyLinesRemover = require('emptylinesremover');
const fs = require('fs');

fs.createReadStream('file1.txt')
  .pipe(new EmptyLinesRemover())
  .pipe(fs.createWriteStream('file2.txt'));

In file2.txt you have this content without empty lines:

London is a capital
of Great Britain

The emptyLinesRemover constructor accepts the following options as well, but all options resends to the constructor stream.Transform (Look at Node.js documentation).


highWaterMark <number> Buffer level when stream.write() starts returning false.
Defaults to 16384 (16kb), or 16 for objectMode streams.

decodeStrings <boolean> Whether or not to decode strings into Buffers before
passing them to stream._write(). Defaults to true

objectMode <boolean> Whether or not the stream.write(anyObj) is a valid
operation. When set, it becomes possible to write JavaScript values other than
string, Buffer or Uint8Array if supported by the stream implementation.
Defaults to false

write <Function> Implementation for the stream._write() method.

writev <Function> Implementation for the stream._writev() method.

destroy <Function> Implementation for the stream._destroy() method.

final <Function> Implementation for the stream._final() method.
