Filter array of objects by nested values using ramda: Sometimes you dont have access to backend and you want to filter the response from an endpoint based on certain criteria. While trivial on flat arrays, this gets a bit tricky if the property you want to query is deeply nested. This is where Ramda shines.

Say we have a prop.users of the shape:

const users = [
    {username: 'bob', age: 30, tags: [{name: 'work', id: 1}, {name: 'boring', id: 2}]},
    {username: 'jim', age: 25, tags: [{name: 'home', id: 3}, {name: 'fun', id: 4}]},
    {username: 'jane', age: 30, tags: [{name: 'vacation', id: 5}, {name: 'fun', id: 4}]}
];

Filter an array by date condition and return certain props only with Ramda.
const array = [{id: 1, createdAt: '2016-09-22 15:55:08'}, {id: 2, createdAt: '2017-11-22 15:55:08'}]
const dateCheck = date =>
new Date(date).getFullYear() >= new Date().getFullYear()
R.pluck('id', R.filter(R.propSatisfies(dateCheck, 'createdAt'))(array))

ssl ceritificates that work

local ssl certificates that work

motivation

in web dev sometimes you are constrained to develop from behind a https:// local server. i spent two days making this work and i want to write it down here, so that next time apple upgrades OS X and i decide to do a clean install (forgetting to backup certain things) i dont waste this amount of time anymore (i hope).

maybe it helps someone else too. that would make me very happy too.

forget openssl

major pita to remember commands. i don't think there is anything better that makes your mom feel like you are a hacker, than showing her how to type:
