Most realtors choose to showcase MLS listing data on their personal websites as a way to drive traffic and make an initial contact with their users. A common tool can be used across many different sites, but we need to give each site a unique look and feel, as well as customize the search for the geographical region and types of properties that the realtor or office serves.
Redman Technologies built a search tool that satisfies these requirements, by interfacing with a common API and accepting a JSON object customizing the style of the site and certain attributes like geogrpahic location. The tool also includes user accounts for saving particular search configurations and favouriting properties. I was entirely responsible for building the front-end of the application.
The biggest challenge was building a custom integration between Vue and Google Maps as there was no existing package that supported our needs. I ended up creating a small package that accepts map data (like pin and polygon data) in a declarative way and uses simple diffing to draw and update the map using Google's API.
Different implementations exist on different realtor's websites. This is one highly-stylized example.
