Trouble with Next js + Express deployment using Zeit Now
Posted By: Anonymous
I have written a simple SSR Next js web page with an express server attached to handle some email functionality I have attached to a contact form.
I have tried deploying to now and, whilst the terminal says I have done so successfully, I get a 502 error when I make network requests to my express server.
now.json:
{
"version": 2,
"builds": [
{"src": "package.json", "use": "@now/next"},
{"src": "/server/index.js", "use": "@now/node-server"}
],
"routes": [{"src": "/api/contact", "dest": "/server/index.js"}]
}
next.config.js:
const { PHASE_PRODUCTION_SERVER } =
process.env.NODE_ENV === 'development'
? {} // We're never in "production server" phase when in development mode
: !process.env.NOW_REGION
? require('next/constants') // Get values from `next` package when building locally
: require('next-server/constants'); // Get values from `next-server` package when building on now v2
module.exports = (phase, { defaultConfig }) => {
if (phase === PHASE_PRODUCTION_SERVER) {
// Config used to run in production.
return {};
}
const withSass = require('@zeit/next-sass');
return withSass();
};
I had a look at now-examples but unfortunately this particular combination of libraries isn’t represented and I’m not skilled enough a programmer to understand the inner workings of them myself.
Any help would be greatly appreciated. My server code is
INDEX.JS
const express = require('express');
const next = require('next');
const bodyParser = require('body-parser');
const mailer = require('./mailer/mailer.js');
const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev })
const handle = app.getRequestHandler()
app.prepare().then(() => {
const server = express();
server.use(bodyParser.json());
server.get('*', (req, res) => {
return handle(req, res);
});
server.post('/api/contact', (req, res) => {
const { firstName, lastName, phoneNumber, emailAddress, messageText } = req.body
mailer.send( firstName, lastName, phoneNumber, emailAddress, messageText ).then(() => {
console.log(`Sent the message "${messageText}" from <${firstName}> ${emailAddress}.`);
res.status(200);
res.send('success')
}).catch((error) => {
console.log(`Failed to send the message "${messageText}" from <${firstName}> ${emailAddress} with the error ${error && error.message}`);
res.status(400);
res.send('failure')
})
});
server.listen( (process.env.PORT || 3000) , (err) => {
if (err) throw err
console.log('> Read on http://localhost:3000')
});
});
The rest of my next.js app is very straightforward.

Solution
you will have to use lambdas with the following now.json
{
"version": 2,
"builds": [
{ "src": "package.json", "use": "@now/next" },
{ "src": "lambda_file.js", "use": "@now/node"}
],
"routes": [
{ "src": "api_route", "dest": "lambda_file.js"}
]
}
