Secrets Management

DotEnv File

Environment variables are used to store sensitive data such as API keys, tokens, and configuration settings outside the source code. This helps keep your code secure and makes it easier to manage different settings for various environments (e.g., local, staging, production). In Bruno, environment variables can be managed through .env files.

DotEnv File for Secret Management

In Bruno, you can store your secrets (e.g., API keys, JWT tokens) in a .env file located at the root of your collection folder. This approach is inspired by how developers typically manage secrets in their codebase.

You cannot create the .env file directly inside Bruno. You need to manually create the .env file at the root of your Bruno collection folder to store your secrets. Once created, you can access those variables within your Bruno collection.

Folder Structure Example

Below is an example folder structure for your collection:

Creating and Using the .env File

1. Create a .env file manually in the root of your collection folder. This file will store your sensitive environment variables.

2. Define your secrets in the .env file. For example:

JWT_TOKEN=your_jwt_token_value
API_KEY=your_api_key_value

These secrets will be accessible in your Bruno collection via the process.env object.

Bruno will automatically load the secrets from this file and make them available to your collection via process.env.<secret-name>.

Your environment file at environments/local.bru would look like

vars {
  baseURL: https://echo.usebruno.com
  JWT_TOKEN: {{process.env.JWT_TOKEN}}
  API_KEY: {{process.env.API_KEY}}
}
 

In this example, the JWT_TOKEN secret from the .env file is referenced using process.env.JWT_TOKEN. This will be replaced with the actual value of JWT_TOKEN when the collection is executed.

Managing Secrets

1. Always add the .env file to your .gitignore file to ensure secrets are not accidentally pushed to version control.

2. If you need to share the structure of your environment variables with other developers, create a .env.sample file without actual secret values.
