How can I attach MongoDB to DO Apps

I have a Express.js application running on DO Apps Platform. I want to attach a Managed Mongo DB component to it but the DATABASE_URL is not connecting with the App.

I am getting this error

App starting error:  MongooseServerSelectionError: self signed certificate in certificate chain

I know the reason behind this. Because i am not specifying the crt file. But i don’t know how to add the crt file in the production. If i just include it in the source files wouldn’t it be a security concern?

Is there any better way to attach mongoDB component to a DO Apps?

Note: I am using Node.js and Mongoose

Here’s a workaround.

ALERT: Not recommended and secured for production. Makes MITM attacks possible. Do so at your own risk.

In your NodeJS component on App Platform, add this as an environment variable

Key as: NODE_TLS_REJECT_UNAUTHORIZED and value as 0

There are safer workarounds to the above though, but for quickly prototyping, the above is fine

Start Using App Platform
