Keep same URL in now.sh
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"
  }
}
```
Replace YOUR_APP_NAME by the name of your app. Then go to your now.json and add/change:
```
"name": "YOUR_APP_NAME",
"alias": "YOUR_UNIQUE_SUBDOMAIN.now.sh",
```
Replace YOUR_UNIQUE_SUBDOMAIN by your unique subdomain. Just run yarn deploy.

Pretty format ELM model in browser

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.

Empty Tag in React

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>
</>

Reuse last argument from previous command
If you need to reuse the reuse the last argument from the previous command this is for you:
```
touch config.js
vi !$
```
Last command is equivalent to
```
vi config.js
```
Bonus: echo $? will display the exit code of therevious command !! will re-execute the previous command, sudo !!
