rollup-plugin-geojson

🍣 An unofficial Rollup plugin which Converts .geojson files to ES6 modules.

Requirements

This plugin requires an LTS Node version (v8.0.0+) and Rollup v1.20.0+.

Install

Using npm:

npm install rollup-plugin-geojson --save-dev

Usage

Create a rollup.config.js configuration file and import the plugin:

import geojson from 'rollup-plugin-geojson';

export default {
  input: 'src/index.js',
  output: {
    dir: 'output',
    format: 'cjs'
  },
  plugins: [geojson()]
};

Then call rollup either via the CLI or the API.

With an accompanying file src/index.js, the local data.geojson file would now be importable as seen below:

// src/index.js
import data from './data.geojson';
console.log(`running version ${data.features}`);
