sum-up by Shinnosuke Watanabe is a perfect example of why Node.js ecosystem is amazing. This module is microscopic in size at just 40 lines of code but if you are writing a CLI tool it can save you 10 mintues of work and spare you the hassle of mundane work.
The only thing sum-up does, and it does it really well, is display a few fields from your own
package.json. It’s as simple as that and nothing more and it even has full test coverage. It’s a tiny building block that will fit practically any CLI utility.
npm install sum-up
var sumUp = require('sum-up'); console.log(sumUp(require('./package.json')));
This will produce a neatly formatted info:
example-sum-up v1.0.0 https://github.com/npmawesome/example-sum-up Example which describes how to use the sum-up module.
I like that Shinnosuke Watanabe released version 1.0 instead of forever iterating on 0.0.x which has been the trend in the last couple of years. I’m a strong advocate of 1.0 releases as soon as it makes sense.
