Environment Variable

Queryx provides a convenient feature for reading from environment variables using the built-in env() HCL function. It is a common practice for applications to read configuration settings from environment variables in production environments. In the following example, by setting QUERYX_ENV to production, queryx will automatically read the database connection URL from the DATABASE_URL environment variable.

hcl

database "db" {
  config "development" {
    url = "postgres://postgres:postgres@localhost:5432/blog_development?sslmode=disable"
  }

  config "production" {
    url = env("DATABASE_URL")
  }
}

database "db" {
  config "development" {
    url = "postgres://postgres:postgres@localhost:5432/blog_development?sslmode=disable"
  }

  config "production" {
    url = env("DATABASE_URL")
  }
}
