How the Strangler Pattern Can Change the Way Think About Refactoring

Test

At Campus Labs, we heavily used the Strangler Pattern during our huge effort from converting a monolithic .NET application to multiple Single Page Apps in front of a suite of microservices. The pattern is essentially where you introduce a new thing to your system, and slowly over time you point clients from the old thing to the new thing. This pattern doesn't have to be used only for converting legacy applications to new applications. The principle behind it can be used for pointing clients to a new api, using a new Front End Component instead of another, or anything in between.
