As HtmlFormatter has been moved to a composer library, in order to make MobileFrontend leaner, and improve the consistency of the api, modularity and quality of the formatter, we want to extract it to a composer library.

Overview

• Create composer package with boilerplate
  • Get it into CI
  • Migrate MobileFrontend's code and tests to the library
    • Decouple from MobileFrontend's globals and code
    • Thoroughly document changes for later migration
  • Ensure library is continuously tested and works well
• Swap implementation in MobileFrontend for the composer library
  • Security review?
  • Verify all is well
• Iterate on mobile formatter to improve the quality of the code
  • Make the external api consistent (for example, use constructor configuration everywhere instead of using some times setters and some times not, etc)
