I’ve bought and used previous versions of Things and have always admired Cultured Code’s attention to design. With Things 3 they’ve made one of the strongest statements yet for native platform software to be as beautiful as it is useful.I’m currently spending time with the new Things and so far it’s going well. Design matters whether you are building for mobile, desktop, or the browser. My wish is that other software makers will use Things as inspiration to exhibit better restraint in their work. I’m naturally drawn to design that shows restraint and Things is a masterpiece in this regard." } , { "title" : "Next.js 2.0", "category" : "", "tags" : "", "url" : "/next-js-2-0/", "date" : "March 27th, 2017", "pubdate" : "2017-03-27", "content" : "Zeit: More than 3.1 million developers read our announcement post of Next.js.

I was recently working on an app that uses Vue and Rails 5 together. The app has a Vue component where administrators can create new users. The new user’s credentials are sent to the Rails server through a POST request from Axios. The Rails app then uses the powerful and flexible Devise gem to handle user creation and authentication.It required a bit of research to learn how to successfully implement this workflow. I’d like to share a few lessons learned in setting this up. Most of the Devise “how to” articles assume you’re using the standard ERB templates that come with the gem, which is obviously antiquated in the new JavaScript heavy world we code in.Configuring AxiosAxios acts as the HTTP client for Vue. All form submissions and data retrieval from the backend are made possible with Axios. When you’re working in Vue it’ll be among the most important packages you’ll rely upon. There are other good HTTP clients available in the JavaScript community but I’ve found Axios to be my favorite.A few small tweaks are needed when importing Axios into your Vue App. These tweaks rely on Axios’ ability to set defaults for use in every request:import Vue from 'vue'import axios from 'axios'let token = document.getElementsByName('csrf-token')[0].getAttribute('content')axios.defaults.headers.common['X-CSRF-Token'] = tokenaxios.defaults.headers.common['Accept'] = 'application/json'Explanation: Import the Vue and Axios packages when creating a new Vue app. Access the CSRF token that Rails displays in a meta tag towards the top of the application.html.erb file and save it as a variable. Tell Axios that every request should include the X-CSRF-Token header with the saved token. Tell Axios that every request should include an Accept header that only allows JSON as the desired response.These configuration defaults tell Rails that requests are valid by including the CSRF Token and that all responses should be formatted as JSON. Axios sets the Accept header to include ALL MIME TYPES out of the box! This is bad for a number of reasons but easily corrected by specifying the configuration default shown in the example. Devise will read this header and return the proper response. If you don’t specify JSON, Devise will send back HTML which is useless to your Vue app.Configuring DeviseDevise is one of the more flexible gems for handling user authentication and registration in the Rails ecosystem. It only requires that one controller be customized to accommodate the registration request sent from Vue.First, edit the routes.rb file to enable Devise and specify that there is a custom registration controller:# routes.rbRails.application.routes.draw do devise_for :users, controllers: { registrations: 'registrations' } root 'home#index'endThen, edit the custom registration controller to allow an authenticated administrator to create a new user from Vue:# app/controllers/registrations_controller.rbclass RegistrationsController < Devise::RegistrationsController before_action :authenticate_user!, :redirect_unless_admin, only: [:new, :create] skip_before_action :require_no_authentication clear_respond_to respond_to :json private def redirect_unless_admin head :unauthorized unless current_user.try(:admin?) end def sign_up(_resource_name, _resource) true endendThis controller is mostly copied from a Stack Overflow answer where a good explanation of the code is already discussed. It is essentially adjusting Devise’s filters to allow an authenticated administrator to create a user then respond to the request with JSON if the front-end client specifies it in the Accept header. We’ve already configured Axios to ask for a JSON response so now Vue and Rails are speaking to each other nicely. You don’t need to make any further changes to Devise. You may be tempted to edit the devise.rb initializer in hopes of troubleshooting this workflow but that isn’t necessary and in some cases may break things.Create a New UserIn the Vue component simply make the POST request to the Rails app with the user credentials stored in the v-model for the form inputs:methods: { onSubmit: function () { axios.post('/users', { user: { email: this.email, password: this.password } }) .then(response => { // whatever you want }) .catch(error => { // whatever you want }) }}The form’s onSubmit method is called by Vue when specified in the template: <form v-on:submit.prevent="onSubmit">.ConclusionIn this article I’ve only covered adding a new user through a Vue front-end as an administrator. However, this same concept can easily be applied to authenticating new sessions, editing user information, and allowing users to register on their own. Once Axios is configured properly to communicate with Devise it’s only a matter of overriding the gem’s controllers to achieve whatever functionality you want." } , { "title" : "Nice and Neat", "category" : "", "tags" : "", "url" : "/nice-and-neat/", "date" : "March 6th, 2017", "pubdate" : "2017-03-06", "content" : "When I first coded this site in Jekyll I decided to make life easy and use Bootstrap to organize the web templates. The main advantage was the nice grid system, mobile responsive navigation, and quick time to launch. It served its purpose by helping me finish the project in a hurry, one weekend, and the results were fine.As time passed I’ve had this notion in my mind that eventually I’d do a rewrite specifically to remove Bootstrap. The site’s layout is minimal and doesn’t justify the full weight of the framework. Also, some of the visual elements from Bootstrap appeared overly default for my taste and I never felt motivated to heavily restyle them. Finally, the responsive menu system was unnecessary because the site’s navigation is simple. Obviously, using a front-end framework has its advantages and can prevent reinventing the wheel. Why write my own custom grid system when there are countless others to choose from?This past Saturday I noticed Thoughtbot had recently released version 2.0.0 of their lightweight grid system Neat. This was all the motivation I needed to start rewriting the site’s templates. I felt an unexpected sense of relief when I removed Bootstrap, almost as if I had regained control of the page. Neat doesn’t affect styling of page elements, it only focuses on the layout grid. Also, I did drop in the tiny Normalize.css library because it offers a sensible baseline to begin customizing the page.Once again the rewrite took a weekend and that proved to me that using a heavy framework like Bootstrap isn’t always the time saver I believed it was. The real value in Bootstrap becomes more apparent when developing a prototype web app. It’s nice when all the buttons, menus, and tables are already formatted. It’s worth mentioning that I could pull in a customized version of Bootstrap that omitted the elements I didn’t need but I honestly never bothered to do that. I would guess that most quick weekend projects people put together just grab the full framework off the CDN.So how did I like using Neat? I loved it! It’s an incredible approach to grids because it’s just a series of SASS mixins you drop into your stylesheets. You assign which items on your page are columns and that’s it. The result is a super lightweight stylesheet and a very flexible grid. It does have a small learning curve as the syntax is a bit unique but it’s not hard to learn. I’d use Neat again for projects both large and small. It’s the type of library that never feels like it’s taken over my project. Those are the libraries I plan to use whenever possible." } , { "title" : "Use Operator Mono and Fira Code Together in Atom", "category" : "", "tags" : "", "url" : "/use-operator-mono-and-fira-code-together-in-atom/", "date" : "March 2nd, 2017", "pubdate" : "2017-03-02", "content" : "Sometimes I find a total gem on Medium that was published several months ago.

Basically, you compose code in an editor pane, complete with customizable syntax highlighting, and can view the results in an adjacent pane as they would appear in the shell. This workflow is fast and elegant.CodeRunner doesn’t include Elixir out of the box but adding a new language is very easy.

A widow is when a line break occurs and a single lonely word is bumped to the next line, left to poke me in eye.Luckily, this can easily be avoided in both Jekyll and Middleman. The goal is to determine if the title is at least two words in length and then replace the last space in the title with an  . This non-breaking space will keep the last two words married together so that in the event of a line break they will always bump down to the next line together.The following code is a Jekyll filter that is used in Liquid templates. Simply place this filter in a file named filters.rb and save it to the _plugins folder (create this file and folder if you don’t have them):# filters.rbmodule Jekyll module WidowFilter def no_widows(title) if title.strip.count(" ") >= 2 title.split[0...-1].join(" ") + " #{title.split[-1]}" else title.strip end end endendLiquid::Template.register_filter(Jekyll::WidowFilter)The filter is easily invoked in a Liquid template:<h1>{{ post.title | no_widows }}</h1>The process is very similar in Middleman except it’s referred to as a helper instead of a filter. Place the following code in the config.rb file:# config.rbhelpers do def no_widows(title) if title.strip.count(" ") >= 2 title.split[0...-1].join(" ") + " #{title.split[-1]}" else title.strip end endendMiddleman supports both Haml and ERB. To use the helper in Haml:%h1= no_widows(article.title)Or in ERB:<h1><%= no_widows(article.title) %></h1>If you view the source code for this site you’ll see that I use the same technique for my titles.
