javascript - How to deploy express.js server to Netlify - Stack Overflow

I am attempting to deploy a Vue.js, Node, Express, MongoDB (MEVN) stack application to Netlify. I successfully deployed the front end of the application to Netlify, and am now attempting to deploy the express server, based on the following serverless-http example: .js

I configured my server to include the serverless-http package:

server.js

const express = require('express');
const app = express();
const serverless = require('serverless-http');
const bodyParser = require('body-parser');
const cors = require('cors');
const mongoose = require('mongoose');
const config = require('./DB.js');
const postRoute = require('./routes');

mongoose.connect(config.DB, { useNewUrlParser: true, useUnifiedTopology: true }).then(
  () => { console.log('Database is connected') },
  err => { console.log('Can not connect to the database'+ err)}
);

app.use(cors());
app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

app.use('/messages', postRoute);

app.use('/lify/functions/server', router);  // path must route to lambda
app.use('/', (req, res) => res.sendFile(path.join(__dirname, '../public/index.html')));


module.exports = app;
module.exports.handler = serverless(app);

routes.js

const express = require('express');
const postRoutes = express.Router();

// Require Post model in our routes module
let Post = require('./post.model');

// Defined store route
postRoutes.route('/add').post(function (req, res) {
  let post = new Post(req.body);
  post.save()
    .then(() => {
      res.status(200).json({'business': 'business in added successfully'});
    })
    .catch(() => {
      res.status(400).send("unable to save to database");
    });
});

// Defined get data(index or listing) route
postRoutes.route('/').get(function (req, res) {
    Post.find(function(err, posts){
    if(err){
      res.json(err);
    }
    else {
      res.json(posts);
    }
  });
});

module.exports = postRoutes;

I then re-deployed my application to Netlify, but the server does not seem to run in Netlify. This server is in a folder in project root of my vue.js app. Should I instead run the server as a separate site in Netlify? If not, what should I do in order to get the server to run when deployed in Netlify?

It's been a while, but here goes.

Netlify hosting is for the Jamstack, as they say, i.e. only static files, no processing on the server. The idea is to make use of other mechanisms to get your data dynamically, such as APIs hosted elsewhere, which you query straight from the browser, or when you build your site.

Most likely you actually had to deploy your express.js app as a Netlify Function, instead. Check Netlify's blog post on running express apps on their functions.

I had a similar issue, just that my server wouldn't connect to the routes locally, the major difference between my code and yours was that I had to do

const router = express.Router()

and then switched app.use() with router.use()

Like I said, that's for when the localhost says "cannot GET /* a defined path */"

P.S. As a side note, you don't need explicit bodyParser in recent express, express.json() works fine instead.
