I was presented to a project that uses SP 2016 on prem and the solution uses a Web API to fetch data from a DB and react to present the data in SP.
My question is how can I create a React web part without using SPFx?
Do I need to create the components, save them in a folder in SP and then use a content editor web part to render the app?
Is there some samples on internet? I found one that show how to create a single page app for SP but what I need is a application that loads in a page as a normal web part.
