My First npm Publish # My first npm publish was unusual. npm didn’t exist at the time, so that presented a bit of a challenge. This is the story of helping to inventing a universe so that I could make an apple pie from scratch. SSJS Back in 2009, I was working at Yahoo! as a Front-End Engineer. That meant that I wrote a lot of PHP and JavaScript. I had just finished a project where we had front-en

Io.js # A lot of people have asked me lately about io.js and its place among Node Forward, the Advisory Board, and npm. This is my own personal point of view. However, I have shared early drafts of this post with the io.js technical committee to ensure that it’s at least a reasonable approximation of how the team sees things. What is io.js? Io.js is a collaborative fork of joyent/node. Io.js is cr

New 2014-06-30: You can contain Zalgo with the dezalgo module Some people asked me to explain what I meant by “releasing Zalgo” in async APIs, so I thought I’d share the following guidelines. Please follow all of these rules in your programs. If you deviate from them, you do so at the peril of your very sanity. Get Over Your Provincial Boilerplate Preferences Personally, I don’t actually care all

At TxJS the other day, I gave a talk where I mentioned that the Unix Philosophy is a crucial part of the patterns, opinions, and culture of Node.js. As usual, I made my slides available online well in advance of the talk video being available. For some reason, this brief mention of “Unix Philosophy” set off a few peoples’ ire. Since I had only 25 minutes, and every slide could probably be its own

git-rebase # Edit: You should probably also read Understanding the Git Workflow. Much more succinct explanation of the point that I dance around a lot below. Almost as if we’d had roughly the same ideas, but he squashed the messages more eloquently ;) A recent article on git-merge vs git-rebase kicked off a very interesting conversation on twitter the other day among a bunch of us nerds. It starte

I’ve been through the paces quite a few times trying to optimize the hell out of very hot code. In the last few years, this has been mostly in V8, of course, but the basic principles are not too far off in different JS environments. It’s important to not put too much weight in rules of thumb, and we programmers are particularly bad at that, given our tendencies towards abstraction. But that discla

Note: This was written quite some time ago. The current ES6 Module specification has changed a lot since then, and many of my complaints have been addressed. Treat this essay as a piece of history. click here to acknowledge this caveat and read the essay. A few things have rubbed me the wrong way about the current Modules and Module Loader specification. I regret that I have not been very clear ab

JavaScript is Not Web Assembly # It’s fairly common these days to think of JavaScript as a sort of “assembly language for the web”. After all, it’s the language that is natively supported by web browsers, making it the most widely deployed runtime in history. With Node, we have a very relevant general purpose non-browser stack for doing system programming using this language, so it’s even more imp

More can be found in the archive. More Stuff I occasionally post things other places. I am very active on GitHub, often in the various projects related to npm and tap.

An Open Letter to JavaScript Leaders Regarding Semicolons # I got this email last night from Sean Silva: I was browsing the code for your npm.js project (this file in particular: https://github.com/isaacs/npm/blob/master/lib/npm.js), and noticed you using a style where you line up your commas under the ‘r’ of your var statements, and under your [ and { in array/object literals. I’m very fond of th

10 Cool Things You Probably Didn't Realize npm Could Do # OMG UPDAET! 2011-06-19 Some of this is no longer 100% accurate, which shouldn’t be very surprising, since it was written 7 months ago, and npm had a major version update since then. Check out the node blog for some of the 1.0 changes. npm is the node package manager. Once upon a time, I would have said “a” node package manager, and the humb
