Official Stately.ai engineering blog

A Next.js project bootstrapped with create-next-app.

• Install
• Run locally
• Create a new blog post
• Shortcodes

Install

1. Clone the engineering blog repository to your machine:
   $ git clone git@github.com:statelyai/eng-blog.git
2. Navigate into the engineering blog folder:
   $ cd eng-blog
3. Install yarn package manager globally if you don’t already have yarn installed on your machine:
   $ npm install -g yarn
4. Install the dependencies for this project:
   $ yarn
5. You’re ready to run the engineering blog

Run locally

1. Run the development server to spawn a local server on port 3000:
   $ yarn dev
2. Visit http://localhost:3000/ to find your server running.

Create a new blog post

Blog posts are stored inside content/posts.

1. Create and checkout a new Git branch for your blog post:
   $ git checkout -b my-blog-post-branch-name
2. Use yarn post:create to create a blog post following the CLI (command-line interface) prompts:
   $ yarn post:create
3. Find your new blog post inside content/posts and write your blog post content using markdown format.
4. Save your file to live refresh the local server and preview your post at http://localhost:3000/. If your changes aren”t visible, you may need to stop and restart the local server to trigger a rebuild:
   $ ^C
$ yarn dev
5. Commit and push your Git branch to the eng-blog repository:
   $ git commit -am "Add new blog post"
$ git push origin my-blog-post-branch-name
6. Create a pull request on GitHub for your Git branch to the eng-blog repository to request that the post is published to the live site.

Edit existing post

Use yarn post:edit to update an existing blog post’s updatedAt frontmatter field. Follow the CLI prompts to choose an existing blog post from the list.

Blog post frontmatter options

property	description
title	post title
description	post description that shows on blog list view
tags	tags relevant to the blog post
author	post author
publishedAt	date the post was first published
updatedAt	date the post was last updated
originalURL	original post URL if post has been copied from another platform

Test meta tags and Open Graph locally

1. Run the development server to spawn a local server on port 3000:
   $ yarn dev
2. In another terminal tab, run yarn test:meta to spawn an instance of localtunnel listening to the same port as the development server:
   $ yarn test:meta
3. The localtunnel process will show a URL in the terminal for a temporary deployment of the development server: your url is: https://exampleurl.com
4. Use this URL with the social media platforms (or any other platform using Open Graph) below to test how they’d preview the home page or any post page meta information:

• Twitter card validator
• LinkedIn post inspector
• Facebook Sharing Debugger (requires Facebook login)

Shortcodes

There are a few shortcodes you can use to embed content in markdown.

Tweets

Use the tweet id for the id attribute. For example, in https://twitter.com/statelyai/status/1461727317429043201, 1461727317429043201 is the ID.

<Tweet id="1461727317429043201" />

YouTube

Use the YouTube ID for the id attribute. For example in https://www.youtube.com/watch?v=y6aGu0N8z9Q, y6aGu0N8z9Q is the ID.

<Youtube id="y6aGu0N8z9Q" />

Visualizer

Use the Visualizer ID for the id attribute. For example in https://stately.ai/viz/5c325385-a0f4-4eaa-b215-712424369cc2, 5c325385-a0f4-4eaa-b215-712424369cc2 is the ID.

A title is also required to describe your visualization for accessibility and testing purposes:

<Viz id="7c0ec648-09d6-46fe-a912-fc0e46da5094" title="Data fetching modeled as a statechart." />

Configure how the visualization embed displays by passing the options below.

1 is show, 0 is hide:

Option	Default value	Available values
mode	"viz"	"viz", "full", "panels"
panel	"code"	"code", "state", "events", "actors"
showOriginalLink	1	1, 0
readOnly	1	1, 0
pan	0	1, 0
zoom	0	1, 0
controls	1	1, 0

// Display in visualization mode
<Viz id="5c325385-a0f4-4eaa-b215-712424369cc2" title="Data fetching modeled as a statechart." />

// Display in panels mode showing the state panel without the link to the visualizer
<Viz id="7c0ec648-09d6-46fe-a912-fc0e46da5094" title="Data fetching modeled as a statechart." mode="panels" panels="state" showOriginalLink="0" />

// Display in visualization mode without any controls
<Viz id="5c325385-a0f4-4eaa-b215-712424369cc2" title="Data fetching modeled as a statechart." controls="0" />
