const analytics = new RudderAnalytics();
analytics.load(<WRITE_KEY>, <DATA_PLANE_URL>);Bundled export will contain the plugins code as part of the bundle in build time.

const analytics = new RudderAnalytics();
analytics.load(<WRITE_KEY>, <DATA_PLANE_URL>);Legacy export will contain the plugins code as part of the bundle in build time and supports legacy browsers like IE11.
import { RudderAnalytics } from '@rudderstack/analytics-js/legacy';
const analytics = new RudderAnalytics();
analytics.load(<WRITE_KEY>, <DATA_PLANE_URL>);How to build the SDK
Look for run scripts in the package.json file for getting the browser minified and non-minified builds. The builds are updated in the dist folder of the directory. Among the others, some of the important ones are:
npm run build:browser:modern: This outputs dist/cdn/modern folder that contains the CDN package contents.npm run build:npm: This outputs dist/npm folder that contains the NPM package contents.
