How to GraphQL Global ID Migration Update

We are pleased to announce that we have now completed the first phase of rolling out the new GraphQL global ID format. This means that all newly created GraphQL objects have IDs that conform to a new format, which we refer to as next IDs. It also means we’ve hit a major milestone as we work towards improving our scalability and speed. In this post, we’d like to give you some details as to how you can begin migrating to the next format for older IDs.

Why is this necessary?

The current format of Global IDs in our GraphQL API will not support our projected growth over the coming years due to limitations with the data encoded in the IDs. The next format gives us the ability to handle your requests even faster by being able to build queries that will be optimized for our database clusters.

New global ID format coming to GraphQL

The GitHub GraphQL API has been publicly available for [over 4 years now]. Its usage has grown immensely over time, and we’ve learned a lot from running one of the largest public GraphQL APIs in the world. Today, we are introducing a new format for object identifiers and a roll out plan that brings it to our GraphQL API this year.

What is driving the change?

As GitHub grows and reaches new scale milestones, we came to the realization that the current format of [Global IDs]in our GraphQL API will not support our projected growth over the coming years. The new format gives us more flexibility and scalability in handling your requests even faster

What are the benefits of cloud migration? Reasons you should migrate

The moving of applications, databases and other business elements from the local server to the cloud server called cloud migration. This article will deal with migration techniques, requirement and the benefits of cloud migration.

In simple terms, moving from local to the public cloud server is called cloud migration. Gartner says 17.5% revenue growth as promised in cloud migration and also has a forecast for 2022 as shown in the following image.

Or you better like to write in one line:

gem 'jekyll-spaceship', group: :jekyll_plugins

Add jekyll-spaceship to the plugins: section in your site's _config.yml.

plugins:
  - jekyll-spaceship

πŸ’‘ Tip: Note that GitHub Pages runs in safe mode and only allows a set of whitelisted plugins. To use the gem in GitHub Pages, you need to build locally or use CI (e.g. travis, github workflow) and deploy to your gh-pages branch.

Additions for Unlimited GitHub Pages

  • Here is a GitHub Action named jekyll-deploy-action for Jekyll site deployment conveniently. πŸ‘
  • Here is a Jekyll site using Travis to build and deploy to GitHub Pages for your references.

Usage

1. Table Usage

For now, these extended features are provided:

  • Cells spanning multiple columns
  • Cells spanning multiple rows
  • Cells text align separately
  • Table header not required
  • Grouped table header rows or data rows

Noted that GitHub filters out style property, so the example displays with the obsolete align property. But in actual this plugin outputs style property with text-align CSS attribute.

Rowspan and Colspan

^^ in a cell indicates it should be merged with the cell above.

Cell Alignment

Markdown table syntax use colons ":" for forcing column alignment.
Therefore, here we also use it for forcing cell alignment.

Table cell can be set alignment separately.

| :        Fruits \|\| Food       : |||
| :--------- | :-------- | :--------  |
| Apple      | : Apple : | Apple      \

|^^    B. Orange        ||^^ 2. Bad   |
|^^    C. Banana        ||  It's OK!  |

Code above would be parsed as:

How's it?
1. Fine
2. Bad
It' OK!

Cell Markdown

Sometimes we may need some abundant content (e.g., mathjax, image, video) in Markdown table
Therefore, here we also make markown syntax possible inside a cell.

| :                   MathJax \|\| Image                 : |||
| :------------ | :-------- | :----------------------------- |

Rowspan is 4 
A. Peach 
B. Orange 
C. Banana
 
How's it?
It' OK!

 

Cell Inline Attributes

This feature is very useful for custom cell such as using inline style. (e.g., background, color, font)
The idea and syntax comes from the Maruku package.

 

Following are some examples of attributes definitions (ALDs) and afterwards comes the syntax explanation:

{:ref-name: #id .cls1 .cls2}
{:second: ref-name #id-of-other title="hallo you"}
{:other: ref-name second}

An ALD line has the following structure:

  • a left brace, optionally preceded by up to three spaces,
  • followed by a colon, the id and another colon,
  • followed by attribute definitions (allowed characters are backslash-escaped closing braces or any character except a not escaped closing brace),
  • followed by a closing brace and optional spaces until the end of the line.

If there is more than one ALD with the same reference name, the attribute definitions of all the ALDs are processed like they are defined in one ALD.

An inline attribute list (IAL) is used to attach attributes to another element.
Here are some examples for span IALs:

{: #id .cls1 .cls2} <!-- #id <=> id="id", .cls1 .cls2 <=> class="cls1 cls2" -->
{: ref-name title="hallo you"}
{: ref-name class='.cls3' .cls4}

Here is an example for custom table cell with IAL:

{:color-style: style="background: black;"}
{:color-style: style="color: white;"}
{:text-style: style="font-weight: 800; text-decoration: underline;"}

|:             Here's an Inline Attribute Lists example                :||||
| ------- | ------------------ | -------------------- | ------------------ |
|:       :|:  <div style="color: red;"> &lt; Normal HTML Block > </div> :|||
| ^^      |   Red    {: .cls style="background: orange" }                |||
| ^^ IALs |   Green  {: #id style="background: green; color: white" }    |||
| ^^      |   Blue   {: style="background: blue; color: white" }         |||
| ^^      |   Black  {: color-style text-style }                         |||

Code above would be parsed as:

IALs

Additionally, here you can learn more details about IALs.

2. MathJax Usage

MathJax is an open-source JavaScript display engine for LaTeX, MathML, and AsciiMath notation that works in all modern browsers.

Some of the main features of MathJax include:

  • High-quality display of LaTeX, MathML, and AsciiMath notation in HTML pages
  • Supported in most browsers with no plug-ins, extra fonts, or special setup for the reader
  • Easy for authors, flexible for publishers, extensible for developers
  • Supports math accessibility, cut-and-paste interoperability, and other advanced functionality
  • Powerful API for integration with other web applications

2.1 Performance optimization

At building stage, the MathJax engine script will be added by automatically checking whether there is a math expression in the page, this feature can help you improve the page performance on loading speed.

2.2 How to use?

Put your math expression within $...$

$ a * b = c ^ b $
$ 2^{\frac{n-1}{3}} $
$ \int\_a^b f(x)\,dx. $

Code above would be parsed as:

MathJax Expression

3. PlantUML Usage

PlantUML is a component that allows to quickly write:

  • sequence diagram,
  • use case diagram,
  • class diagram,
  • activity diagram,
  • component diagram,
  • state diagram,
  • object diagram

There are two ways to create a diagram in your Jekyll blog page:

```plantuml!
Bob -> Alice : hello world
```

or

@startuml
Bob -> Alice : hello
@enduml

Code above would be parsed as:

PlantUML Diagram

4. Mermaid Usage

Mermaid is a Javascript based diagramming and charting tool. It generates diagrams flowcharts and more, using markdown-inspired text for ease and speed.

It allows to quickly write:

  • flow chart,
  • pie chart,
  • sequence diagram,
  • class diagram,
  • state diagram,
  • entity relationship diagram,
  • user journey,
  • gantt

There are two ways to create a diagram in your Jekyll blog page:

```mermaid!
pie title Pets adopted by volunteers
  "Dogs" : 386
  "Cats" : 85
  "Rats" : 35
```

or

@startmermaid
pie title Pets adopted by volunteers
  "Dogs" : 386
  "Cats" : 85
  "Rats" : 35
@endmermaid

Code above would be parsed as:

Mermaid Diagram

5. Media Usage

How often did you find yourself googling "How to embed a video/audio in markdown?"

While its not possible to embed a video/audio in markdown, the best and easiest way is to extract a frame from the video/audio. To add videos/audios to your markdown files easier I developped this tool for you, and it will parse the video/audio link inside the image block automatically.

For now, these media links parsing are provided:

  • Youtube
  • Vimeo
  • DailyMotion
  • Spotify
  • SoundCloud
  • General Video ( mp4 | avi | ogg | ogv | webm | 3gp | flv | mov ... )
  • General Audio ( mp3 | wav | ogg | mid | midi | aac | wma ... )

There are two ways to embed a video/audio in your Jekyll blog page:

Inline-style:

![]({media-link})

Reference-style:

![][{reference}]

[{reference}]: {media-link}

For configuring media attributes (e.g, width, height), just adding query string to the link as below:

6. Hybrid HTML with Markdown

As markdown is not only a lightweight markup language with plain-text-formatting syntax, but also an easy-to-read and easy-to-write plain text format, so writing a hybrid HTML with markdown is an awesome choice.

It's easy to write markdown inside HTML:

<script type="text/markdown">
# Hybrid HTML with Markdown is a not bad choice ^\_^

## Table Usage

| :        Fruits \|\| Food       : |||
| :--------- | :-------- | :--------  |
| Apple      | : Apple : | Apple      \
| Banana     |   Banana  | Banana     \
| Orange     |   Orange  | Orange     |
| :   Rowspan is 4    : || How's it?  |
|^^    A. Peach         ||   1. Fine :|
|^^    B. Orange        ||^^ 2. Bad   |
|^^    C. Banana        ||  It's OK!  |

## PlantUML Usage

@startuml
Bob -> Alice : hello
@enduml

## Video Usage

![](https://www.youtube.com/watch?v=Ptk_1Dc2iPY)
</script>

7. Markdown Polyfill

It allows us to polyfill features for extending markdown syntax.

For now, these polyfill features are provided:

  • Escape ordered list

7.1 Escape Ordered List

A backslash at begin to escape the ordered list.

Normal:

1. List item Apple.
3. List item Banana.
10. List item Cafe.

Escaped:

\1. List item Apple.
\3. List item Banana.
\10. List item Cafe.

Code above would be parsed as:

Normal:

1. List item Apple.
2. List item Banana.
3. List item Cafe.

Escaped:

1. List item Apple.
3. List item Banana.
10. List item Cafe.

8. Emoji Usage

GitHub-flavored emoji images and names would allow emojifying content such as: it's raining :cat:s and :dog:s!

Noted that emoji images are served from the GitHub.com CDN, with a base URL of https://github.githubassets.com, which results in emoji image URLs like https://github.githubassets.com/images/icons/emoji/unicode/1f604.png.

In any page or post, use emoji as you would normally, e.g.

I give this plugin two :+1:!

Code above would be parsed as:

I give this plugin two :+1:!

8.1 Emoji Customizing

If you'd like to serve emoji images locally, or use a custom emoji source, you can specify so in your _config.yml file:

jekyll-spaceship:
  emoji-processor:
    src: "/assets/images/emoji"

See the Gemoji documentation for generating image files.

9. Modifying Element Usage

It allows us to modify elements via CSS3 selectors. Through it you can easily modify the attributes of an element tag, replace the children nodes and so on, it's very flexible, but here is example usage for modifying a document:

# Here is a comprehensive example
jekyll-spaceship:
  element-processor:
    css:
      - a: '<h1>Test</h1>'                     # Replace all `a` tags (String Style)
      - ['a.link1', 'a.link2']:                # Replace all `a.link1`, `a.link2` tags (Hash Style)
          name: img                            # Replace element tag name
          props:                               # Replace element properties
            title: Good image                  # Add a title attribute
            src: ['(^.*$)', '\0?a=123']        # Add query string to src attribute by regex pattern
            style:                             # Add style attribute (Hash Style)
              color: red
              font-size: '1.2em'
          children:                            # Add children to the element
            -                                  # First empty for adding after the last child node
            - "<span>Google</span>"            # First child node (String Style)
            -                                  # Middle empty for wrapping the children nodes
            - name: span                       # Second child node (Hash Style)
              props:
                prop1: "1"                     # Custom property1
                prop2: "2"                     # Custom property2
                prop3: "3"                     # Custom property3
              children:                        # Add nested chidren nodes
                - "<span>Jekyll</span>"        # First child node (String Style)
                - name: span                   # Second child node (Hash Style)
                  props:                       # Add attributes to child node (Hash Style)
                    prop1: "a"
                    prop2: "b"
                    prop3: "c"
                  children: "<b>Yap!</b>"      # Add children nodes (String Style)
            -                                  # Last empty for adding before the first child node
      - a.link: '<a href="//t.com">Link</a>'   # Replace all `a.link` tags (String Style)
      - 'h1#title':                            # Replace `h1#title` tags (Hash Style)
          children: I'm a title!               # Replace inner html to new text

Example 1

Automatically adds a target="_blank" rel="noopener noreferrer" attribute to all external links in Jekyll's content.

jekyll-spaceship:
  element-processor:
    css:
      - a:                                     # Replace all `a` tags
          props:
            class: ['(^.*$)', '\0 ext-link']   # Add `ext-link` to class by regex pattern
            target: _blank                     # Replace `target` value to `_blank`
            rel: noopener noreferrer           # Replace `rel` value to `noopener noreferrer`

Example 2

Automatically adds loading="lazy" to img and iframe tags to natively load lazily. Browser support is growing. If a browser does not support the loading attribute, it will load the resource just like it would normally.

jekyll-spaceship:
  element-processor:
    css:
      - a:                                     # Replace all `a` tags
          props:                               #
            loading: lazy                      # Replace `loading` value to `lazy`

In case you want to prevent loading some images/iframes lazily, add loading="eager" to their tags. This might be useful to prevent flickering of images during navigation (e.g. the site's logo).

See the following examples to prevent lazy loading.

jekyll-spaceship:
  element-processor:
    css:
      - a:                                     # Replace all `a` tags
          props:                               #
            loading: eager                     # Replace `loading` value to `eager`

There are three options when using this method to lazy load images. Here are the supported values for the loading attribute:

  • auto: Default lazy-loading behavior of the browser, which is the same as not including the attribute.
  • lazy: Defer loading of the resource until it reaches a calculated distance from the viewport.
  • eager: Load the resource immediately, regardless of where it’s located on the page.

How to perform migration rollback in laravel

As we know that laravel migration provides very simple way to create database table structure. We need to create migration file and write table structure then migrate that migration. Sometimes we need to rollback that migration. So here we will discuss about the migration rollback in laravel.

We can run the rollback artisan command to rollback on a particular step. We can execute the following artisan command.

php artisan migrate:rollback --step=1

Every time when we will rollback, we will get the last batch of migration.

**Note: **This rollback command will work on laravel 5.3 or above version. For the version below 5.3, there is no command available for migration rollback in laravel.

We can also use the following command to rollback and re migrate.

php artisan migrate:refresh --step=2

It will rollback and remigrate last two migration.

You can also checkout the article for executing single migration by clicking on the link below.

How to migrate single migration in laravel

Sometimes while working on a laravel application, we just need to migrate only single or specific migration. If we run normal migrate command it will migrate all the migrations written in the application. Here i will let you know to migrate single migration in laravel.

Migrations play very important role for aplication’s database structure. We just need to create migrations in the application for each table which you want and whenever we migrate these migrations. New table structure would be created.

For new developers or setting up new environment, we do not need to backup of table structure. We will just need to run the migrations. It will automatically create desired tables in the database connected from the laravel application.

We can run all the migrations using the command below.

php artisan migrate

Now if we want to run only one migration or a specific migration, we will need to define a path parameter and will need to specify the path of that migration file which we want to run like below.

php artisan migrate --path=/database/migrations/my_migration.php

It will migrate only my_migration.php file. Here, you will need to replace file name from your own migration file.
