在 express.js 中设置默认路径

Question

app.set('views', path.join(__dirname,'views'))

What is the meaning of the line above? And what is the purpose of it?

Answer 1

That line of code indicates the main path of your views, for example if you have this hierarchy:

 views/index.html views/home/index.html views/home/news/index.html

would render your views like this:

 res.render('/index.html', /*...*/); res.render('home/index.html', /*...*/); res.render('home/news/index.html', /*...*/);
