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 🙏

JCAMP-DX converter

Parse and convert JCAMP-DX data

Installation

Node JS

npm install jcampconverter

Bower

bower install jcampconverter

Methods

convert(jcamp, [options])

Converts the jcamp using options.
Returns an object with information about the converted file and uncompressed spectra data.

Arguments

  • jcamp - String or ArrayBuffer containing the JCAMP-DX data
  • options - Object with options to pass to the converter

Options

  • keepRecordsRegExp - regexp to select which records should be placed in the info field. By default: :/^$/} (nothing is kept)
  • withoutXY - do not parse XYDATA or PEAKTABLE fields. Useful to only extract metadata fields (combine this option with keepRecordsRegExp)
  • chromatogram - use the new GC/MS data format output (default: false)
  • canonicDataLabels - canonize data labels (uppercase) (default: true).
  • canonicMetadataLabels - canonize data labels (uppercase) (default: false).
  • dynamicTyping - When parsing field convert to number if a number (default: true)

2D NMR options:

  • noContour - if true, the contour levels will not be generated. Instead the raw data will be available in result.minMax.z (default: false)
  • nbContourLevels - number of contour levels to use in each positive and negative sides (default: 7)
  • noiseMultiplier - default: 5
  • keepSpectra - Generate array for 2D NMR spectra (default: false)

Use as a module

Node.JS

var converter = require('jcampconverter');
var jcamp = require('fs').readFileSync('path/to/jcamp.dx', 'utf8');

var result = converter.convert(jcamp);

// if there is only one spectrum it will be in
console.log(result.flatten[0]);

// the converter will also keep the full jcamp tree
