Compatibility with node.js

[tylerlong]

I first installed mermaid via npm install mermaid
Then I created index.temp.js with only one line: require('mermaid');

It doesn't work for me:

$ node index.temp.js 
/some-path/node_modules/mermaid/src/mermaid.js:19
import * as Logger from './logger';
^^^^^^

I am using es2015 features. The pre-compiled libraries have been transformed to ecmascript5 via babel.

If you use require directly you need to apply babel yourself.

This has caused me some headache and I am thinking of rolling back to not use es2015 yet. Still deciding though.

Closing issue as it's resolution is included in release 0.5.6. Let me know if you do not agree.

👍 I will have a try. If I don't respond, then it means I find no problem.

Thank you for your work!

It works with node.js now.

But it still depends on browser, you cannot do it purely in node.js.

I found this todo in code: https://github.com/knsv/mermaid/blob/master/src/mermaidAPI.js#L486

I will create a separate issue for this.
