Missing documents for requiring `gl` as dev dependency in `luma.gl`

Unit tests complain about missing gl in dependency

We are requiring luma.gl in our app. In our basic rendering unit test, we see a bunch of errors such as

  console.error node_modules/luma.gl/dist/es5/webgl-context/create-headless-context.js:27
    WebGL not available in Node.js, install using "npm install gl".
    Cannot find module 'gl' from 'create-headless-context.js'

It turns out that we’d need to add gl to our dev-dependency to pass these warnings. yarn add gl --dev

To Do List

• Doc update Is there other better way to support unit tests? If not, it would be nice if we can add these requirements to the testing documentation.

Hi @shanshanzhu and @ibgreen we are trying to use deck.gl with nextjs with SSR and getting exactly the error while building app. What you would suggest for workaround?

1. It is not an error, just a notification. It just says that while luma.gl was successfully imported, you won’t be able to call createGLContext without installing gl.
2. I believe this error was removed a long time ago. What luma.gl version are you using?
