A Guide to Building a Map Application with Svelte

This guide shows how to create a highly interactive and reactive map application using Svelte MapLibre GL. To start, set up a new Svelte project using the command "npx sv create .". Then, install Svelte MapLibre GL with the command "npm install --save-dev svelte-maplibre-gl". Next, add a basic map by replacing the content of src/routes/+page.svelte with the provided code. Build the Svelte application with the command "npm run dev" to see the map. Adding markers to the map is also easy, and an example is provided to place a marker at Sapporo Station in Japan. The main advantage of this map library is its reactivity, which can be demonstrated by updating the code to show real-time interactions. The guide also provides a demo repository for reference and suggests next steps, including adding features and deploying with AWS Amplify. Overall, creating a map application with Svelte MapLibre GL is easy and reactive. With this guide, you can get started quickly and explore more advanced features later.
