Added test to check that the library importable in server-side context

[timocov]

Related issue #446.

In #484 @NekitCorp fixed importing the library in server-side context, but we need to be sure that it won't happen in the future. To avoid this, we need to add a test in CI to check that the library might be imported in nodejs context without any error (just imported, don't need to create chart or whatever).

Any news on that one? I currently have a lot of tests failing which makes it unable to deploy my app as the build is not passing on CI. Is there a workaround or anything? I get the typical error that I've found in other issues here too:

    import { bindToDevicePixelRatio } from 'fancy-canvas/coordinate-space';
    ^^^^^^

    SyntaxError: Cannot use import statement outside a module

Any workarounds?

My workaround was to add the libraries to the transformIgnorePatterns in the Jest config.

This doesn't solve the root cause, but sufficient as a workaround.

    "transformIgnorePatterns": [
      "node_modules/(?!(lightweight-charts|fancy-canvas)/)"
    ]

But only if you are not using an UNejected Create React App. In this case you could run them via CLI to bybass this issue, see https://github.com/facebook/create-react-app/issues/2537#issuecomment-390341713.

It not worked for me.

My workaround was to mock the module in setupTests.js

jest.mock('lightweight-charts', () => ({}));
