Heroku NodeJS-无法获取/

Question

I have a Heroku server with BootBot running over it. But I'm having difficulties trying to render a HTML page from it. This is what I'm doing:

var app = express();
var path = require('path');
app.use(express.static(path.join(__dirname)));
app.get('/test', function (req, res) {
    res.sendFile(path.join(__dirname + 'test.html'));
});
app.listen(3000, function() {
    console.log("The server is running.");
});

My root directory has both index.js and test.html.

My Procfile is: web: node --inspect ./index.js

Everything I've tried sends me to the same "Cannot GET /test" .

Is there something I'm missing?

If I set app.listen(process.env.PORT)

State changed from starting to crashed

Answer 1

You need template engine like ejs or blade when you want to render html page from node.Js.

npm install ejs --save

And these lines to your index.js file

// ~ render html files with ejs 
app.use(express.static(path.join(__dirname))); 
app.set('views', __dirname);
app.set('view engine', 'html');
app.engine('html', require('ejs').renderFile);

app.get('/test', function (req, res, next) {
    res.render('test.html');
});

I hope this helps you. if it does not reach me with the comments.
