A little tool to convert css to elm-css Snippets
#!/usr/bin/env node
const fs = require("fs");
const parse = require("css").parse;
const path = require("path");
if (process.argv.length !== 3) {
const exec = path.basename(process.argv[1]);
console.log(`usage ./${exec} input.css`);
console.log("converts css to elm-css snippets");

Someone in the Elm slack channel threw out this idea of naming Msg in the past tense, and not imperatively. I thought it was an interesting idea and I adopted the practice, just to try it out. I forgot who it was, I wish I could give them credit.

Anyway, the ramifications were more than I expected, and not simply the same Msg with different names. What I started doing is naming Msg as if they were saying "This happened". So where I would say "HandleUsernameField" I might instead say "UsernameFieldChanged" or instead of "Close" I would do "XClicked". What I didnt account for was that Msg and functionality dont map one to one. So for example, if you have a Msg named Navigate, its going to be the one Msg you use whenever you want to navigate. But if you are naming Msg as paste-tense descriptions, then several different things could happen that could cause a navigation. Since many things should cause a navigation, naming Msg in the past tense leads to lots of Msg which do the same thing.

Why do I have to write JSON decoders in Elm?

A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.

Reactiflux #redux discussion: top-down single connect vs multiple lower connects

May 12, 2016

[8:23 PM] jrajav:: Heya. I'm wondering what the function of components really are. Just don't fully understand - why not just pass in the state with something like store.subscribe( () => render( , document.getElementById('root') ) ) ?

[8:24 PM] jrajav:: Passing in dispatch functions as well

[8:24 PM] jrajav:: Then, split apart the state as appropriate further down for each subcomponent

[8:25 PM] jrajav:: If all of the components are pure, stateless functional components this approach should still be just as performant, right?

A style guide for Elm tools

Haskell Style Guide for Elm

Goal: a consistent style throughout all Elm projects that is easy to read and produces clean diffs to make debugging easier. This means valuing regularity and simplicity over cleverness.

Line Length

Keep it under 80 characters. Going over is not the end of the world, but consider refactoring before you decide a line really must be longer.
