Missing exports warning from `yarn build`

See original GitHub issue

The following warning is produced from yarn build:

$ yarn build

yarn run v1.22.4
$ rollup --config

src/index.ts → dist/metamask-onboarding.cjs.js, dist/metamask-onboarding.es.js...
created dist/metamask-onboarding.cjs.js, dist/metamask-onboarding.es.js in 1s

                                    ^
178:     if (browserInfo.browser.name === 'Firefox') {
179:       return 'FIREFOX';

And we do have a namedExports option defined for cjs:

We solved changing the import line in index.ts from:

import * as Bowser from 'bowser';

to:

import Bowser from 'bowser';

and settings allowSyntheticDefaultImports to true inside tsconfig.json (compilerOptions).

Hope someone will find this useful.
