@esri/arcgis-rest-request

This package exists to expose the node-fetch package in a consistent way for both Node JS 12.16+ and various bundlers with consistent TypeScript types based on the browser types.

This exposes a getFetch() method that returns a Promise that resolves with fetch, Headers, Request and Response. This is async because it uses import("node-fetch") under to hood to load node-fetch@3.0.0 which is ESM only. The only way to load an ESM module in CommonJS in Node is to use the async import().

The package.json contains fields for the following:

• main - undefined, Node JS should use the exports field and conditional exports.
• module - Exposes a ESM module. Used by Rollup and Parcel v2.
• browser - Exposes a CJS module. Used by Parcel v1 and Browserify.
• exports - exposes conditional exports config with the following conditions. Used by Webpack and soon to be others:
  • module - ESM module exposing browser globals.
  • browser - CJS module exposing browser globals.
  • import - ESM module exposing node-fetch.
  • require - CJS module exposing node-fetch.
  • default - ESM module exposing browser globals.
