基于URL express动态切换app engine

Question

How Do I set App Engine based on URL?

I got two render engine for my application, serverSideRenderEngine & browserRenderEngine

If, url is /home app.engine should be set as serverSideRenderEngine

If, url is /login app.engine should be set as browserRenderEngine

Current for all url's, I'm setting my app.engine to browserRenderEngine

Below is my app engine code,

app.set('view engine', 'html');
app.set('views', distFolder);
app.engine('html', browserRenderEngine) // it set to browserRenderEngine by default;

So how do I switch based on URL? Please help

Answer 1

you can use a middleware like:

 app.use((req, res, next) => {
    // check the url
    if(req.originalUrl.startsWith('/home')  ) {
        app.engine('html', serverSideRenderEngine) 
     }
    else {
        app.engine('html', browserRenderEngine) 
    }
    next();
});
