Anguar server encountered a startup issue and failed to initialize

My server.js file looks like this:

var express = require('express'),
    api     = require('./api'),
    app     = express();

app
    .use(express.static('./public')) 
    .use('./api', api)
    .get('*', function (req, res) { 
        res.sendfile('public/main.html'); 
    })
    .listen(3000);

The server.js file is located in C:\Users\myName\Desktop\prodfixes\server.js and main.html can be found in C:\Users\myName\Desktop\prodfixes\public\main.html. When I visit http://localhost:3000/, no error is displayed on the screen. However, when running the server using nodemon server.js, I encounter the following error message: express deprecated res.sendfile: Use res.sendFile instead. After updating res.sendfile to res.sendFile, a new error occurs upon refreshing the screen:

TypeError: path must be absolute or specify root to res.sendFile at ServerResponse.sendFile (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\response.js:394:11) at C:\Users\myName\Desktop\prodfixes\server.js:9:7 at Layer.handle [as handle_request] (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\layer.js:95:5) at next (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\route.js:131:13) at Route.dispatch (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\route.js:112:3) at Layer.handle [as handle_request] (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\layer.js:95:5) at C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\index.js:277:22 at param (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\index.js:349:14) at param (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\index.js:365:14) at Function.process_params (C:\Users\myName\Desktop\prodfixes\node_modules\express\lib\router\index.js:410:3)

I am still learning Angular and server setup, so any guidance would be highly appreciated. Thank you.

Answer №1

To fix this issue in a way that works on all platforms, you can use the path.resolve method:

var express = require('express'),
    path = require('path'),
    api = require('./api'),
    app = express();

app
    .use(express.static('./public')) 
    .use('./api', api)
    .get('*', function (req, res) { 
        res.sendFile(path.resolve('public/main.html')); 
    })
    .listen(3000);

The path.resolve function will give you the absolute path of the file needed for the res.sendFile() method to work correctly:

Make sure the path is absolute unless the root option is specified in the options object.

Visit expressjs.com for more information.

Answer №2

My thoughts align with S. Buda's... it appears that you may be on the incorrect path. The error message states "TypeError: path must be absolute or specify root to res.sendFile at ServerResponse.sendFile" - consider using the complete path rather than a relative one. For example, use C:\Users\myName\Desktop\prodfixes\public\main.html instead of just public/main.html.
