Welcome to the next version of the ArcGIS API for JavaScript (4.24). This version of the API is currently in development and will be updated frequently until the production release in July 2022. Try out new features, perform regression testing, and get a feel for the next release - then share your feedback with the development team. Please make sure that bugs and enhancement requests are specific to https://js.arcgis.com/next and not applicable to a released version.

Please note: ArcGIS API for JavaScript release management is dynamic. Some new features and updates that appear in js.arcgis.com/next might not be present in the final production release due to a variety of factors (but will likely be present in an upcoming release).

Read about the current version of the JavaScript API at https://developers.arcgis.com/javascript/.

Read the CHANGELOG.md to find about new functionality, bug fixes and any breaking changes in the next version.

Use CDN or npm to try the next version.

To test the 'next' version using the hosted version, simply reference the API and CSS from our CDN to start using the API in your app.

<link rel="stylesheet" href="https://js.arcgis.com/next/esri/themes/light/main.css">
<script src="https://js.arcgis.com/next/"></script>

The next version of the CDN is not available for download.

The next version is available for testing with local builds. For all new applications, use the ES modules: npm install @arcgis/core@next. Existing applications using AMD modules can run npm install arcgis-js-api@next or consider upgrading to @arcgis/core. More information is available in the SDK's Introduction to tooling guide topic.

Or if you're using esri-loader to help load AMD modules, use options.version and specify next as the value. You can also lazy-load js.arcgis.com/next/esri/themes/light/main.css by adding the css: true option, or you can use any of the other methods supported by esri-loader instead.

const options = {
  version: 'next',
  css: true
};
const [Map] = await loadModules(['esri/map'], options);

Typings are included with the npm install of @arcgis/core@next ES modules. For most use cases, no special TypeScript configurations are required by the API.

The typings are also included with arcgis-js-api@next AMD modules, and they can be used in two ways.

main.ts

/// <reference types="arcgis-js-api" />

tsconfig.json

{
  "compilerOptions": {},
  "include": [
    "node_modules/arcgis-js-api/index.d.ts",
    "src/**/*.ts",
    "src/**/*.tsx"
  ]
}
