In the world of static file hosting there are plenty of solutions. I picked now.sh. It’s free, easy to use and works well. I have had one problem with now.sh so far, it creates a new URL everytime you push. It’s a feature that I dont need in some cases, here’s how to solve. Put this in package.json:

{
  "scripts": {
    "deploy": "now && now alias && now remove YOUR_APP_NAME --safe -y"
  }
}

"name": "YOUR_APP_NAME",
"alias": "YOUR_UNIQUE_SUBDOMAIN.now.sh",

Touch is mainly known for creating files. Touch main purpose is actually to update the file’s timestamp. From the man:

The touch utility sets the modification and access times of files. If any file does not exist, it is created with default permissions.

Using Debug.toString is really helpful to help debug the model but the format of the output is hard to read. Looking for solution I stumbled upon this gem(not the ruby gem). I changed it to work in elm 0.19 and fix a minor issue when using custom type for the Model. Here’s the final result on Gist.

When you need to return more than one element you have few solutions.

Wrap with an element

<div>
  <span>1</span>
  <span>2</span>
</div>

Return a list (requires a key)

function List() {
    return [<span key='1'>1</span>, <span key='2'>2</span>]
}

Use Fragment (16.2.0+)

<Fragment>
  <span>1</span>
  <span>2</span>
</Fragment>

Use empty tag (some kind of alias for Fragment)

<>
  <span>1</span>
  <span>2</span>
</>

If you need to reuse the reuse the last argument from the previous command this is for you:

touch config.js
vi !$

vi config.js

I love calendars and shell has a way to display the calendar for the current month

$ cal

I don’t have much time to write complete articles, so I’ll start publishing Today I learned short articles

In the previous part of this tutorial we’ve seen how to represent the current month view into a list of dates. Now let’s see how we transform this data into something similar to the screenshot below.

ELM was redesign recently and Date and Time have been removed from the core to the Time library. With that in mind let’s build a calendar.

Before in ELM 0.18 if you used evancz/url-parser you would use parseHash to parse the fragment. But now in 0.19 elm/url doesn’t have such function. It is still possible to parse the hash though.

One of my favorite things about ELM is the compiler, it will catch errors before they could make their way to production. Let’s have a look at the most common Javascript errors and see how ELM makes sure they don’t bother you.

I’ve been working with ELM for 2 years now. When I started I had very little knowledge about functional programming. I remember being skeptic about it at first then falling in love with it. Now going back to ReactJS or AngularJS feels like trading a swiss army knife for a hammer.
