After years, I want to add another approach by using a view engine in Express.js
var fs = require('fs');
app.get('/test', function(req, res, next) {
var html = fs.readFileSync('./html/test.html', 'utf8')
res.render('test', { html: html })
// or res.send(html)
})
Then, do that in your views/test if you choose res.render method at the above code (I'm writing in EJS format):
<%- locals.html %>
That's all.
In this way, you don't need to break your View Engine arrangements.
