What is "--env production"?
As a web developer, I have come across the term "--env production" quite often. This is an important command that is used when deploying a web application to a production environment. In simple terms, "--env production" is a flag that tells the application to use the production environment settings instead of the development environment settings.
Why is it important?
During development, we often use different settings such as debug mode or different database credentials to make debugging easier. However, these settings are not suitable for a production environment where security and performance are the primary concerns. We need to make sure that the application is optimized and secure.
How to use "--env production"
To use "--env production", we need to specify it while running the command to start the application. For example:
npm start -- --env production
This command would start the application using the production environment settings. The exact settings would depend on how you have configured your application.
Other ways to use it
There are other ways to use "--env production" depending on your application framework or build system. For example:
- In Angular CLI, we can use "--configuration production" flag instead of "--env production".
- In Webpack, we can specify the environment variable "NODE_ENV=production" to use the production settings.
It's important to check the documentation of your specific framework or build system to see how to use "--env production" or its equivalent.
