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 🙏

Nikita: Content extraction from documents

TODO

  • Fix hardcoded temporary directory, clean up after upload
  • Test some PDF files
  • Add a wrapper graph which takes an object in, enriches then sends out again
  • Integrate with AMQP, add as worker in thegrid-apis

Later

  • Test how much faster Tika Java API is at XHTML + image extraction over cli tools
  • Avoid temporary files for images+html output if/when passing to NoFlo

Setup

Configuration is passed as environment variables:

AMAZON_API_ID: Amazon S3 API identifier
AMAZON_API_TOKEN: Amazon S3 API token/secret
AMAZON_API_REGION: Amazon S3 region, ex: 'us-west-2'
AMAZON_API_BUCKET: Amazon S3 bucket for uploaded files, ex: 'thegrid-user-content'

Design

Separate Heroku worker, integrated into TheGrid APIs.

Inputs:

  • URL to s3 backed document (Word,PDF)

Outputs:

  • Extracted HTML with img src referring to S3 backend

Notes:

  • Tika provides full XHTML document, where as Embed.ly gives only (and we expect)
