ECMAScript module (ESM) support

[gk-bbai]

When using @featbit/js-client-sdk within an Angular project, esbuild prints this error when building the application:

▲ [WARNING] Module '@featbit/js-client-sdk' used by 'apps/promodel-ai/src/app/feature-flags/services/feature-flag.service.ts' is not ESM

CommonJS or AMD dependencies can cause optimization bailouts.
For more information see: https://angular.dev/tools/cli/build#configuring-commonjs-dependencies

Would it be feasible to support ESM in this project to avoid optimization issues in modern frontend apps?

Hello @gk-bbai ,

The SDK is built for both UMD and ESM, you can clone the repo and do

npm run install
npm run build

The folder dist will be created and you will find two releases: umd and esm

So it's weird to see the warning you posted. Can you create an example Angular project to reproduce the warning? That would help us to identify the issue.
