The apihandyman.io website

The API Handyman blog uses Jekyll and Github pages among other things.

Install and run

The Jekyll Serve serve task defined in .vscode/tasks.json starts when the repo folder is opened in VS Code. It creates the necessary docker image and starts it. Open http://localhost:4000

git clone https://github.com/arno-di-loreto/apihandyman.io
code apihandyman.io

Writing

Creating a new post

To create a new post, use the "New Post" VS Code task:

• Open VS Code command palette (command-shit-p)
• Run task
• New Post
• Set title
• Choose a category
• Set a publish date

This will create:

• post branch
• md file in _posts
• images directory in images

Note: Post banner and thumbnail are the same image (images/<post directory>/banner.png or images/<post directory>/banner.jpg).

Set excerpt

This text will be shown on posts list.

But not this one

Images

Images are located in images/<post url>directory, you only need the relative filename to include them:

{% include image.html source="xkcd.png" caption="XKCD: Workflow" url="https://xkcd.com/1172/" %}

Quotes

{% include quote.html 
    author="Hyrum Wright"
    source="Hyrum's Law"
    url="https://www.hyrumslaw.com/"
    text="With a sufficient number of users of an API, it does not matter what you promise in the contract: all observable behaviors of your system will be depended on by somebody."
%}

HTTP Status Codes

HTTP Status Codes information can be embedded using the following styles:

• quote: All data as a quote
• rfc: RFC number (RFC XXXX)
• rfcname: RFC number and name
• rfcfull: RFC number, name and url
• code: Code only
• reason: Reason only
• If no style is provided, the value is code and reason

{% include http-status-code.html code="405" style="quote" %}

HTTP status code data are defined in _data/http-status-codes.yaml and RFC data are defined in _data/rfcs.yaml.

Code blocks

Code blocks look like this:

What the toolbar buttons do (from left to right):

• The first button (double arrow) is for expanding/shrinking the code block content.
• The second button (file icon) opens the file which is shown in code block (when using codefile)
• The third one copy the code block content (that can be simplified) to clip board

Inline code blocks

{% code language:<language> numbers:<true|false> highlight:"<range1,...,rangeN" %}
some code
{% endcode %}

Parameters:

• title (optional): the block title
• language (mandatory): the language used
• numbers (optional): showing line numbers or not (true by default)
• highlight (optional): a set of line index (1) or range (3-4) separated by , to highlight

Inline code block with lines highlighted

{% code language:yaml numbers:false highlight:"1, 3-4" %}
some: inline
code: which
will: be
hightlighted: by prism
{% endcode %}

Inline code block with customized copy

What is below {{site.codeblock_hidden_copy_separator}} will be copied.

{% code title:"Modifying an entire object value" language:bash %}

[apihandyman.io] $jq '.info.contact' demo-api-openapi.json
{
  "name": "The Banking API team",
  "email": "[email protected]",
  "url": "developer.bankingcompany.com"
}
[apihandyman.io] $jq '.info.contact = { name: "The Awesome Banking API Team", url: "www.bankingcompany.com" }' demo-api-openapi.json | jq '.info.contact'
{
  "name": "The Awesome Banking API Team",
  "url": "www.bankingcompany.com"
}

{{site.codeblock_hidden_copy_separator}}

jq '.info.contact' demo-api-openapi.json
jq '.info.contact = { name: "The Awesome Banking API Team", url: "www.bankingcompany.com" }' demo-api-openapi.json | jq '.info.contact'

{% endcode %}

File code block

Instead of writing code block inline, a file can be included:

{% codefile title:"$filename" file:demo-api-openapi.json %}

Parameters:

• filename (mandatory): the file to include (Files are searched in code/<post url> folder if no folder is specified in file.)
• title (optional): the block title (Use $filename to set title to the actual filename)
• language (mandatory): the language used
• numbers (optional): showing line numbers or not (true by default)
• highlight (optional): a set of line index (1) or range (3-4) separated by , to highlight

Asciinema

Check my AscriiptnemA tool to easily record pre-scripted bash sessions using asciinema.

{% include asciinema.html 
          src="/code/api-toolbox-jq-and-openapi/part-3/replace.cast" title="Replacing elements"
          poster="npt:1:20" %}

Videos

Add following data in _data/thirdpartycontents.yaml:

the-augmented-api-design-reviewer-asc:
  source: youtube
  id: MAHW5DmM9j4
  preview: /images/thirdpartycontents/the-augmented-api-design-reviewer-asc.jpg

Then use the following code to include it in a post:

{% include video.html title="the-augmented-api-design-reviewer-asc" %}

Slide decks

Slide decks files are located in slidedecks folder.

slidedecks
├── a-quest-for-simplicity
│   ├── a-quest-for-simplicity.pdf
│   ├── index.html
│   └── slides
│       ├── slide-001.png
│       ├── slide-002.png

They can be included in a post with:

{% include slidedeck.html title="a-quest-for-simplicity" %}

Publishing

Publishing is done automatically by the Publish action (.github/workflows/publish.yml) when merging/pushing on the main branch. This action does the following:

• Cloning the repo
• Launching Jekyll build using docker
• Pushing the build to gh-pages
• Cleaning Cloudflare cache
