toolbox's Introduction

Toolbox

This is a collection of tricks, tools, libraries, APIs and data sources for creative projects. It's a reference as well as a compendium of things you can do in the browser and the command line.

Although this is a list of mostly Github-hosted tools, it's different from awesome-* lists in that I try to avoid having several things with overlapping purposes and only include what I consider to be the excellent ones: tools that are easy to install, elegant to work with, and well documented β€” plus some quirky outliers for good fun.

I've been inspired to keep this list, and name it as such, by javierarce/toolbox, which serves a similar purpose and contains great resources that I recommend you check out.

Contributions to this list are welcome via issues and pull requests β€” I'm always looking for new ideas!

Thanks for stopping by. ✌️

JavaScript libraries

(The β˜… star denotes popular, high-quality, choices.)

Image processing, optical character recognition (OCR)

Repo Description Notes
β˜… tesseract.js Tesseract.js is a javascript library that gets words in almost any language out of images.
β˜… jimp An image processing library written entirely in JavaScript for Node, with zero external or native dependencies.
omggif JavaScript implementation of a GIF 89a encoder and decoder. For making GIFs. Animated_GIF, for example, builds on top of this library.

Web scraping, data extraction

Repo Description Notes
artoo artoo.js is a piece of JavaScript code meant to be run in your browser's console to provide you with some scraping utilities. Allows you to create custom bookmarklets to scrape a web page from your browser; I could see this being used in places where on a server you'd have to jump through some hoops, e.g. getting your Facebook saved links.

fathom A framework for extracting meaning from web pages. Seems to be still a work in progress, but it will ultimately be a tool for understanding where some particular type of content is on a page: "Where is the body? The title? Is this a 'next page' button? Is this a comment form, and are there comments here? By better understanding the parts of a page, we can improve our understanding of how a user interacts with it." β€” source
readability A standalone version of the readability library used for Firefox Reader View. Extract the main content from a web page.

Language processing

Miscellaneous tips & tricks

Start a server for a folder

Run python -m SimpleHTTPServer in your project folder to make it available at http://localhost:8000.

Note: The syntax above is for the Python 2.x that comes preinstalled with macOS and Linux. The equivalent syntax for Python 3 is python -m http.server.

If you're using Node.js, you can also use the serve package, which you can run without installing with npx (it comes with recent versions of npm):

npx serve

An even simpler server is servor:

npx servor

Also take a look at budo.

Fetch a file from the web

To fetch a file from the web with the command line, using wget is straightforward:

wget http://download.geofabrik.de/europe/romania-latest.osm.pbf

πŸ‘‰ See more wget tricks

Or, fetching a file in Node:

require('http').get('http://download.geofabrik.de/europe/romania-latest.osm.pbf', function(response) {
    response.pipe(require('fs').createWriteStream('romania-latest.osm.pbf'));
});

Make an S3 bucket publicly available

To use a S3 bucket to keep a bunch of files and make them publicly available, you need to make a bucket policy. This is under Permissions section on the Properties tab for your bucket. Paste this into the bucket policy (myBucketName should be the name of your bucket):

{
	"Version": "2012-10-17",
	"Statement": [
		{
			"Sid": "PublicReadGetObject",
			"Effect": "Allow",
			"Principal": "*",
			"Action": "s3:GetObject",
			"Resource": "arn:aws:s3:::myBucketName/*"
		}
	]
}

All the files inside will typically be available at http://myBucketName.s3.amazonaws.com/path/to/file but you can grab the exact URL from the Static Website Hosting section in the Properties tab.

Extra credit: This is super-useful for hosting video files, since S3 supports partial content requests which is needed to loop <video> on your web pages.
