mvt-reader

Features

• Decodes and reads Mapbox vector tiles in Rust
• Provides an API for accessing layer names and features within a vector tile
• Can be used as a WebAssembly module in JavaScript (enabled by the wasm feature)

Build the project

cargo build --release

Run tests

cargo test
wasm-pack build --release --target nodejs -d pkg/node -- --features wasm && npm test

Usage

To use the mvt-reader library in your Rust project, add the following to your Cargo.toml file:

[dependencies]
mvt-reader = "1.1.0"

Then, you can import and use the library in your code:

use mvt_reader::{Reader, ParserError};

fn main() -> Result<(), ParserError> {
  // Read a vector tile from file or data
  let data = vec![/* Vector tile data */];
  let reader = Reader::new(data)?;

  // Get layer names
  let layer_names = reader.get_layer_names()?;
  for name in layer_names {
    println!("Layer: {}", name);
  }

  // Get features for a specific layer
  let layer_index = 0;
  let features = reader.get_features(layer_index)?;
  for feature in features {
    todo!()
  }

  Ok(())
}

WebAssembly Usage

To use the mvt-reader library as a WebAssembly module in JavaScript, you can install it with npm and use it in your JavaScript code:

const { Reader } = require('mvt-reader')
const fs = require('fs')

// Example usage
const reader = new Reader(fs.readFileSync('path/to/tile.mvt'))
const layerNames = reader.getLayerNames()
console.log(layerNames)

// More code...
