I am developing a plugin for authentication in Kibana 7.8 oss version  
In that plugin, showing error while using console.log() statement  
For resolving the error, I tried to declare console variable first and gave it Console type and then used console.log(). But didn't work

Here's the code:

> ```
> let console: Console;
> console.log('Attempt to login with google');
> 
> ```

Here's the error:  
`Uncaught TypeError: Cannot read property 'log' of undefined`

**How to use console.log() and debugger in plugin components  
Is there any dev mode?**

Are you certain the code is running on the browser and not the server?

`console.log` should work in the browser, however you'll get an eslint warning. To make sure the code is running in the browser, double check that it lives in a `myPlugin/public` directory.

You can't use `console.log` on the server; instead you should use core's [logging service](https://github.com/elastic/kibana/blob/master/docs/development/core/server/kibana-plugin-core-server.logger.md). You can learn more about it in the [README](https://github.com/elastic/kibana/blob/master/src/core/server/logging/README.md).
