I'm trying to push my application to Heroku, but I'm running into some issues:
Error: ENOENT: no such file or directory, open '.env' 2019-04-10T01:38:23.050188+00:00 app[web.1]: 1 at Object.openSync (fs.js:438:3) 2019-04-10T01:38:23.050190+00:00 app[web.1]: 1 at Object.readFileSync (fs.js:343:35) 2019-04-10T01:38:23.050192+00:00 app[web.1]: 1 at Object.

It seems that the error is the variable envConfig, but i need it for database to work.
As of now, I'm getting
Here is my config/database.js:

const envConfig = dotenv.parse(fs.readFileSync('.env'))

- If those are your real credentials you should invalidate them immediately. They are forever promised, and you need to generate new ones. Editing them out of your question is not enough. – Chris Commented Apr 10, 2019 at 2:39

Reset to default 6Before you do anything else, if those are your real credentials you should invalidate them immediately. They are forever promised, and you need to generate new ones. Editing them out of your question is not enough.
You can change
const envConfig = dotenv.parse(fs.readFileSync('.env'))
to
const envConfig = dotenv.config({silent: true})
You don't need to manually read the file here, and skipping it lets you gracefully handle the case when it doesn't exist. There's also no need to manually set values in process.env:
for (var k in envConfig) {
process.env[k] = envConfig[k]
}
This can be entirely skipped. Dotenv takes care of this itself. Therefore, you don't need envConfig either, reducing all of that to just
dotenv.config({silent: true})
If .env exists, its contents will be added to what's already in process.env. In development, this gives you a convenient way to set your database connection information.
In production, .env shouldn't exist, and your database connection information definitely shouldn't be hard-coded. Instead, your database connection information should e from one or more Heroku config vars (these are environment variables that should already be available via process.env). Your database addon has probably already set the DATABASE_URL variable for you.
For things in your .env that you've set yourself, set a Heroku config var for its production value. You can do that through the Heroku web dashboard or via the Heroku CLI:
heroku config:set SOME_VARIABLE=foo
