What is viewport-mercator-project?

The viewport-mercator-project npm package is a utility library for performing viewport-related calculations in web mapping applications. It is particularly useful for converting between geographic coordinates and screen coordinates, handling zoom levels, and managing map projections.

What are viewport-mercator-project's main functionalities?

Project geographic coordinates to screen coordinates

This feature allows you to project geographic coordinates (longitude, latitude) to screen coordinates (x, y) based on the current viewport settings.

const { WebMercatorViewport } = require('viewport-mercator-project');

const viewport = new WebMercatorViewport({
  width: 800,
  height: 600,
  longitude: -122.45,
  latitude: 37.78,
  zoom: 12
});

const screenCoords = viewport.project([-122.45, 37.78]);
console.log(screenCoords); // [400, 300]

Unproject screen coordinates to geographic coordinates

This feature allows you to convert screen coordinates (x, y) back to geographic coordinates (longitude, latitude) based on the current viewport settings.

const { WebMercatorViewport } = require('viewport-mercator-project');

const viewport = new WebMercatorViewport({
  width: 800,
  height: 600,
  longitude: -122.45,
  latitude: 37.78,
  zoom: 12
});

const geoCoords = viewport.unproject([400, 300]);
console.log(geoCoords); // [-122.45, 37.78]

Get bounding box of the viewport

This feature allows you to get the geographic bounding box of the current viewport, which can be useful for determining the area currently visible on the map.

const { WebMercatorViewport } = require('viewport-mercator-project');

const viewport = new WebMercatorViewport({
  width: 800,
  height: 600,
  longitude: -122.45,
  latitude: 37.78,
  zoom: 12
});

const bounds = viewport.getBounds();
console.log(bounds); // [[-122.519, 37.704], [-122.381, 37.856]]
