How to Pull in Heroku Postgres Credentials for Next-Auth in Next.js

When developing applications that require database connectivity, one common challenge is handling database credentials securely. Hardcoding sensitive information like database URLs is a practice you should avoid to keep your application safe. In this guide, we'll tackle a specific scenario: how to pull in Heroku Postgres credentials using Next-Auth in a Next.js application.

Problem Overview

A developer faced a common issue when trying to integrate their Next.js application with Postgres hosted on Heroku. The dilemma arises from Heroku's best practices that discourage hardcoding credentials. Instead, the developer tried to pull in the required database URL asynchronously using Heroku's API, but encountered problems appropriately assigning the fetched credentials to the database property in the Next-Auth configuration.

The key concern here is managing asynchronous data fetching and correctly utilizing the returned promise to assign the value in a logical manner.

Solution Breakdown

To ensure you're able to pull in the Postgres credentials correctly for Next-Auth, there are key adjustments you need to make in your code. Let's break down the solution step by step.

1. Understanding the Asynchronous Nature of getCredentials

The first step is recognizing that the getCredentials function is asynchronous, which means it returns a promise. This informs how you'll manage its output when configuring the Next-Auth database connection.

2. Correctly Awaiting the Credentials

In your Next-Auth options configuration, you need to wait for the getCredentials function to resolve before assigning its value to the database property. Here is the crucial line of code you should modify:

Key Takeaways

Ensure Asynchronous Handling: Always use await when dealing with promises to ensure that the resolved value is assigned correctly.

Avoid Hardcoding Sensitive Data: By using environment variables and Heroku's API, you're adhering to best practices for security.

Conclusion

Integrating Postgres with Next-Auth in your Next.js application can be straightforward once you handle the asynchronous nature of fetching credentials properly. By modifying your function to properly await the resolution of the promises, you ensure that your application operates securely and efficiently, free from the pitfalls associated with hardcoding sensitive information.

Start integrating confidently, knowing that your database credentials are accessed safely and correctly!
