I want to know if there are some best practices to use Magento 2 as a headless E-commerce solution.

A typical E-commerce in 2017 is to have an omni-channel solution which includes

• E-commerce
• CMS
• Multiplatform
• Tier system integration (ERP, ...)

I want to know how involve Magento 2 API with this kind of solution.

My approach:

• Use a different frontend framework (such as angular) for desktop/mobile webapp and mobile app

• Only use Magento 2 API in order to retrieve or interact with E-commerce data/action

• Only use CMS API in order to retrieve CMS data.

Pro: Only API's, omnichannel

Cons: Limitation for performance/features/formatting

Some questions for this approach :

• Who is responsible for formatting data, for example prices. Magento API and frontend framework?
• Who is responsible for resizing product images and cache them? Because in the native Magento 2 API there is no resize or cache system.
• Do I need to create new custom isolated API or extend native for future upgrade purpose?
• Do you recommend to use an extra layer in order to combine CMS and Magento API?

I appreciate you to share your return in experience.

Moreover, I found this approach: http://fbrnc.net/blog/2015/10/super-scaling-magento
