# 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](https://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=(... dotenv) |
|
``` |
|
|
|
## Usage |
|
|
|
Create `.env` file inside your project root directory and put your 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 |
|
``` |
|
You can even mix both formats, although it's probably a bad idea. |
|
|
|
### ZSH_DOTENV_FILE |
|
|
|
You can also modify the name of the file to be loaded with the variable `ZSH_DOTENV_FILE`. |
|
If the variable isn't set, the plugin will default to use `.env`. |
|
For example, this will make the plugin look for files named `.dotenv` and load them: |
|
|
|
``` |
|
# in ~/.zshrc, before Oh My Zsh is sourced: |
|
ZSH_DOTENV_FILE=.dotenv |
|
``` |
|
|
|
## Version Control |
|
|
|
**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's supposed to be local only. |
|
|
|
## Disclaimer |
|
|
|
This plugin only sources the `.env` file. Nothing less, nothing more. It doesn't do any checks. It's designed to be the fastest and simplest option. You're responsible for the `.env` file content. You can put some code (or weird symbols) there, but do it on your own risk. `dotenv` is the basic tool, yet it does the job. |
