Environment variables

See env/.env.defaults for more details

Define local variables for local development

You can create a .env.development.local file in the env folder to define environment variables for local development. This file is typically ignored by Git, so you can use it to store sensitive or environment-specific information that you don't want to commit to your repository.

If a variable is defined in both the .env.development.local file and the .env.defaults file, the value in the .env.development.local file will take precedence. This allows you to override the default values for certain variables when developing locally, while still maintaining a set of default values that can be used in other environments.

Deployment environment:

process.env.NODE_ENV enum: 'development' | 'production'

backend-server(JAVA) service api address

process.env.BACKEND_BASE_URL default: http://localhost:8081/api/v1/
