GitLab | GitHub

1) Automated toots

Using the code example from my quick_toot project, we will setup automated tooting of text and an image.

• Create app
• Get token
• Test toot
• https://mastodon.cloud/web/accounts/731776

2) Create our node.js project

• Create index.js
• Create package.json

3) Fetch Covid stats

From this API, we will grab the latest coronoa stats.

• Global: https://disease.sh/v2/all
• United States: https://disease.sh/v2/countries/us
• Format data into text to toot

4) Render a Pie Chart

Using the stats fetched, let's create a pie chart using D3, rendered using canvas

5) Schedule to run every day with GitLab

Using gitlab CI/CD, let's schedule this to run every day for our project

• Create .gitignore
• Create Dockerfile
• Create .gitlab-ci.yml
• Git Push
• Setup schedule

6) Line chart showing 7 day moving average of both deaths and cases

• Parse historical data into 7 day moving average
• Render into multi-line chart for both deaths and cases
• Include dependancies for headless chrome in docker

7) Line chart

• 7-day rolling average
• Deaths
• Cases
• 2 y axis labels
• Color coated

8) Deployment docker deps

• Chrome headless docker deps
• GitLab CICD

9) Region / Locations

• Countries
• US State

10) Subscriptable

• On each run, via Mastodon

• Look through latest notifications to me (limit 50)

• If notification msg is @me and has "sub" / "unsub"

• Look at the toot it was in reply_to - Grab region code after "#covid_"
  • Add the user to a mastodon list (and follow them first) by the name of the country code
• If no reply_to, check for #code
• While generting toots for each region

• Check if we have a list by that region name, grab it's users
• Add them into the toot msg as @
