Get Started

ArcGIS REST JS can be deployed with a variety of build tools, including:

• From a CDN
• webpack, Rollup and Parcel
• AMD (Require.js or Dojo)
• Node.js
• What's New in v2.0.0?

Requirements

ArcGIS REST JS takes advantage of web standards that are supported in all modern desktop browsers and most mobile browsers.

• Fetch Support
• Promises Support
• FormData Support
• ECMAScript 5 Support

Browser Support

ArcGIS REST JS is supported in the same browsers as the ArcGIS API for JavaScript.

• Chrome
• Edge
• Firefox
• Safari 9 and later
• iOS Safari
• IE11

IE11 and older mobile browsers require polyfills.

• Promise polyfill
• Fetch polyfill

Node.js Support

ArcGIS REST JS is supported in Node.js 8.x and above. It requires additional packages to polyfill Fetch and FormData.

We recommend the ones below:

• node-fetch - to polyfill Fetch
• isomorphic-form-data - to polyfill FormData

const fetch = require('node-fetch');
const { setDefaultRequestOptions, request } = require('@esri/arcgis-rest-request');

// use node-fetch for each request instead of relying on a global
setDefaultRequestOptions({ fetch })

request(url)
  .then(response)

Other versions of Node.js may also work with appropriate polyfills but we cannot guarantee support.
