TypeScript compiler needs to be configured to output ES6 module by setting --module es6 or the equivalent tsconfig.json compilerOptions parameter. Since tsc --build does not accept compiler options flags, we need to duplicate some of the configuration: - specify separate output folder for ES6 module files (new tsconfig.esm.json file) - add "module" field for ES6 module (esm) output files to package.json Hence, a script `scripts/sync-esm-config.js` was added to automate this process.
