I was looking through the comments hoping to find a tool like this. You did not let me down, fellow HNer! I try to use the command line whenever I can. Somehow there is a command line tool for just about everything, except for the obvious cases where it not useful like visual media and graphs.

I don't want to dissuade you if curses-based UIs are your thing. But one thing that's been crucial to me from Day 1 is that you can type "tad foo.csv" at the command line and immediately get a usable view of your data with no extra config or tweaking needed. I mostly launch tad from the command line.

I just launched "tad 311_Service_Requests_from_2010_to_Present.csv" (a 10GB dataset from data.cityofnewyork.us) and it ate up all my memory without ever showing any data. "vd 311_Service_Requests_from_2010_to_Present.csv" shows the first rows instantly, and I can start rearranging columns while it is still loading, and I can press Ctrl-C to stop the load (and the rows already loaded are still available). No config or tweaking needed.

One drawback of Node.js is that it's single threaded. Moreover, even if somehow it became multithreaded today, JS is absolutely not ready for that. (Btw. yes, async I/O is nice, but threads are useful for more than just I/O.) NPM is quite basic, it pretty much just downloads tarballs recursively from a webserver according to some version spec. The CommonJS module format is fairly loose (and kind of outlived its usefu…

I never said it was, it's not part of it per se, but it's the 'blessed' module/package system on Node.js (the correct capitalization). Which is really sad, because CommonJS is retarded (a file has to actually be executed in order to get it's require & export characteristics and they might arbitrarily change in runtime). It's sad that Node.js as well as the JS ecosystem in general is fairly hostile towards ES6 modules - basically any current support of ES6 modules is just translating then / dumbing them down back to CJS. Hopefully this'll change in the future as ES6 gets more adopted and CommonJS will be left to rot (a fate it deserves and should've already met ages ago).

I downloaded this when this post came up and have been using it steady. It's good. Reliable, does a job that needs doing, has a few bells and whistles.

Definitely still early stage, but that will pass.

I have showed it to a couple people I work with and they have started using it too.
