Conditionally loading packages based on environment.

Based on the environment of the project (production or development), there is a way to load packages conditionally. We may want to load packages conditionally to keep an easier to run development server, for instance.

In order to achieve this, we may use the following technique, if the used packages do not already feature a parameter to be used accordingly to the environment.

For instance we may provide an APP_ENVIRONMENT parameter in the .env file of the project. Based on the value of the parameter, we may load or not a package.




let modules = {

if (process.env.APP_ENVIRONMENT !== "development")
