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 🙏

Readme

ByteArray

the ByteArray is an object that inherits from Array. There are 3 features added to it.

the .from method

ByteArray.from(args) returns a new ByteArray.

args

args can be zero or more paramters of type Number or String or an Array of these type including Arrays.

Strings are interpreted as numbers written in hexadecimal notation. Every String passed, that contains chars other than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f is an Error

if a Number is larger than 255 it will be split into 8bit Bytes. so ByteArray.from(256) returns [1,0]

examples

ByteArray.from(1) returns [1]

ByteArray.from(1,2,3) returns [1,2,3]

ByteArray.from(1,"2",[3]) returns [1,2,3]

ByteArray.from("010203") returns [1,2,3]

ByteArray.from("01",[2,"03"]) returns [1,2,3]

ByteArray.from("01",[2,["03",4],5]) returns [1,2,3,4,5]

ByteArray.from(0x010203) returns [1,2,3]

ByteArray.from(0x010203,[4,"05"],6,0x0708) returns [1,2,3,4,5,6,7,8]

.toString()

returns a string representing the Array in hexadecimal notation.

examples

ByteArray.from(1,2,3).toString() returns "010203"

ByteArray.from(0xff0203,[4,"05"],6,0x0708) returns "ff02030405060708"

.set

arr.set(data, offset) inserts data into the Array at an offset.

data

data passed here will be turned into a ByteArray. see ByteArray.from()

The resulting Array will be spliced into the array at the offset passed here as well. overwriting exactly the number of items passed.

if the length of the passed array plus the offset is larger than the originl Array, it will be expanded.

offest defaults to 0 and can be omitted

examples

ByteArray.from(1,2,3,4,5,6).set("aabb",2).toString() returns "0102aabb0506"

ByteArray.from(1,2,3,4,5,6).set(0xaabb,2).toString() returns "0102aabb0506"

ByteArray.from(1,2,3,4,5,6).set([0xaa,0xbb],2).toString() returns "0102aabb0506"

ByteArray.from(1,2,3,4).set("aabbccdd",2).toString() returns "0102aabbbbccdd"
