[Meta] Ideas to further improve the project

[timbru31]

Hi there,

I'm a big fan of automating all the things and tests for a higher code quality and noticed some things that could be improved in this repository. 🎉
Below are some ideas.

• Write unit tests
• Write E2E tests
• Enable ESLint
• Enable automatic tests and linting via a CI (e.g. TravisCI)
• Add an .editorconfig file for consistent code style rules
• Enable Greenkeeper to keep the dependencies up to date
• Scan for potential vulnerabilities via e.g. snyk or nsp
• Add PR and Issue templates for better issues and PRs
• Consistent dependency range (^ vs ~ vs fixed)
• Publish the project to npm (and add package.json entries like license, bugs, description, ...)

If you have any questions, I'm happy to elaborate or even assist - though my time for open source is limited.
