I have taken over an old e-commerce project for four or five years. The front-end project built by JQ + easy UI has been iterating again. Now the development is very difficult. The goal is to embed angular6 framework into the project. On the basis of not changing the functions of the old project, the new version of requirements will be embedded and used after the completion of angular6.
The background of the problem and what methods have you tried
The background is that the back-end interface server is huge and complex, and the front-end code is chaotic. When we are ready to start a new stove and quickly complete the new requirements, we gradually migrate the old code. At present, the method we want to use iframe to embed, but the risk assessment is insufficient. (including packaging problem, iframe path problem, etc. How to adapt to multi environment change / development / testing / online)
Please teach us a better way to embed or assess the risk and roughly explain the solution. Thank you very much!
