Technical discovery on replacing DTL with a modern FE framework

[abroddrick]

Issue description

Before deciding on if/when to replace DTL with a modern FE framework such as react or vue, we first need to do technical discovery to determine how we can iteratively add a framework to out system and what impact that would have.

Ideally, we would want to avoid having to change the FE all at once, given it would mean halting progress on features completely. Thus, the focus should be to finding a solution where we can slowly have pages being re-developed in the new system while the current DTL is still live.

Acceptance criteria

• use the discovery template to help facilitate discovery for adding a new FE
• as part of technical discovery, propose options for handling this along side your suggested approach
• Consider at least the following during discovery:
  • determine how we could add in a FE into our system, but still have DTL templates working
  • how long would this take for a piece of our system vs the whole system?
  • which FE framework is most compatible for this iterative approach
  • impacts of replacing DTL on the analyst side vs the Registrar user facing side first
  • impacts for in-progress features
• confer with other engineers as needed and get feedback from a dev lead
• share and go over the proposed options with product/program team
• visual representation of the proposed plan and architecture impacts
