Dotenv2env NPM

dotenv2env

dotenv2env is a command line tool that loads environment variables from a .env file and runs a script with those variables as part of the environment. It supports both npm and yarn package managers.

A good use for this library is in conjunction with the babel-plugin-transform-inline-environment-variables, which enables you to inline environment variables directly into your code during the build process.

Here is an example of how to use dotenv2env with babel-plugin-transform-inline-environment-variables and expo

npx dotenv2env start

Usage

To use dotenv2env, run the following command:

npx dotenv2env <script-name> [options]

The following options are available:

--useFile : Use the specified file as the source of environment variables. Defaults to .env.

--useVerbose: Enable verbose logging.

--useYarn: Use yarn as the package manager instead of npm.

In addition to these options, the user can pass other flags that will be forwarded to the script execution.

Example

To run a script named start with environment variables from a .env file using npm, run the following command:

npx dotenv2env start

To run the same script using yarn instead of npm, run the following command:

npx dotenv2env start --useYarn

To use a different file name for the environment variables, run the following command:

npx dotenv2env start --useFile env.prod

Please note that the --useFile, --useVerbose, and --useYarn parameters are reserved for the library, and all other flags that are passed will be forwarded to the script execution.
