A Mobile-friendly map view

- Generation of location-specific meta screenshots for engaging social media preview images.

Auto updates

Each hour, the application would check for new locations in specific communities and (if a sub-reddit exists) posts for any new locations in a standard post format:

Goals

Provide a Mobile-friendly view of Locations of Interest
Raise awareness of Locations of Interests in our community.
Lower anxiety for those seeking updates about their community.

Tech

Up-to-date social Media sharing icons created for each town/city

Design

[Ingest] An n8n workflow that reads the CSV file published by the MoH. Locations are then categorized and saved in a sqllite db via n8n.
An endpoint (also n8n) that returns all the locations in the last 30 days.
A statically rendered Next.JS site that is published each hour. A mobile-friendly interactive map with all locations marked.
A hourly job to build sub-reddit content and sent updates to places with new/updated Locations of Interest.
Self-referential automatic meta image generation

Why so complex?

To reduce the complexity, cost and on-going maintenance cost of the application, i removed the n8n workflow the Next.JS site build on and replaced it with direct calls to the MoH API.

This allowed the site to be fully independent of my own local infrastructure and for its whole lifetime, run entirely for free on Vercel

Christchurch Water Reporter

chch-water-reporter (live site)

This is an attempt at representation of water usage in christchurch, its goal was to raise awareness for water conservation and the need for more broad understanding of how we consume our natural resources.

With over 170,000 addresses on the map, the app required a dynamic rendering system to enabled smooth scrolling across 170,000 points, without compromising on performance or detail display on the map.
