I installed with "yarn" when I import ReactSpeedometer, it shows this error.

Answer 1 · 2020-04-09T08:07:56.000Z

can you share a reproducible code sandbox or something?

@laitanop or maybe something like a reproducible repo where I can check this issue ... thanks ...

Here is a codesandbox link where it works fine - https://codesandbox.io/s/stoic-hooks-rjcvu?file=/src/App.js

My guess is that your build system does not understand es6 module identifiers like import/export ... , Almost all of the react app templates, for eg: create-react-app will support this out of the box ... I can share an example repo created with create-react-app where things are working

@laitanop To verify this, you can downgrade to 0.10.x and see if it works fine. Because in v0.11.0, the library moved to lodash-es from lodash as former provides tree shaking resulting in smaller bundle sizes in your final app bundle. You can see the CHANGELOG for more details. If that is the case, you might want to upgrade your app bundling to support es6 module code imports ...

I'm closing this issue since this seems like a problem around the bundling setup of the project, and not the library itself. Please reopen if you find issues with the library itself.

I encountered the same issue on a project started with create-next-app. Downgrading to 0.10.x resolved the issue.

Thanks for the good work.

ok ... Alternatively you can use babel to make your bundling process understand es6 modules out of the box, so that you can keep using libraries like lodash-es that export es6 modules ...
