Deploy to Heroku fails with npm ERR! missing script: start

[mariotatis]

Hi Guys,
I've tried to deploy the json-graphql-server to Heroku, but, I'm still not able to do do.

I'm getting npm ERR! missing script: start

Can you please guide me on the correct way to configure the Heroku Procfile or package.json to properly getting the server running on Heroku?

Thanks a lot.

Guys, I managed to solve the issues to deploy successfully to Heroku

1- Add a Procfile

Add a file to the project root folder Procfile with the following:

web: npm start

2- Add start script in package.json

    ....
       "scripts": {
        ...
        "start": "bin/json-graphql-server.js db.js"
    },
    ...

3- Update bin/json-graphql-server.js

Removed the Port and Host definitions
Update the app.listen

#!/usr/bin/env node
require('reify');
var path = require('path');
var express = require('express');
var JsonGraphqlServer = require('../lib/json-graphql-server.node.min').default;

var dataFilePath = process.argv.length > 2 ? process.argv[2] : './data.json';
var data = require(path.join(process.cwd(), dataFilePath));
var app = express();

app.set('port', (process.env.PORT || 3000));
app.use('/', JsonGraphqlServer(data));
app.listen(app.get('port'));

Now, server runs in Heroku with no issues.

It will continue to work in your local env in your http://localhost:3000/
