# dotenv
|
|||
|
|
|
|||
|
|
Automatically load your project ENV variables from `.env` file when you `cd` into project root directory.
|
|||
|
|
|
|||
|
|
Storing configuration in the environment is one of the tenets of a [twelve-factor app](http://www.12factor.net). Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
|
|||
|
|
|
|||
|
|
## Installation
|
|||
|
|
|
|||
|
|
Just add the plugin to your `.zshrc`:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
plugins=(git man dotenv)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
Create `.env` file inside your project directory and put your local ENV variables there.
|
|||
|
|
|
|||
|
|
For example:
|
|||
|
|
```sh
|
|||
|
|
export AWS_S3_TOKEN=d84a83539134f28f412c652b09f9f98eff96c9a
|
|||
|
|
export SECRET_KEY=7c6c72d959416d5aa368a409362ec6e2ac90d7f
|
|||
|
|
export MONGO_URI=mongodb://127.0.0.1:27017
|
|||
|
|
export PORT=3001
|
|||
|
|
```
|
|||
|
|
`export` is optional. This format works as well:
|
|||
|
|
```sh
|
|||
|
|
AWS_S3_TOKEN=d84a83539134f28f412c652b09f9f98eff96c9a
|
|||
|
|
SECRET_KEY=7c6c72d959416d5aa368a409362ec6e2ac90d7f
|
|||
|
|
MONGO_URI=mongodb://127.0.0.1:27017
|
|||
|
|
PORT=3001
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**It's strongly recommended to add `.env` file to `.gitignore`**, because usually it contains sensitive information such as your credentials, secret keys, passwords etc. You don't want to commit this file, it supposed to be local only.
