# 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.
|
|
|
|
To use it, add `dotenv` to the plugins array in your zshrc file:
|
|
|
|
```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.
|
|
|
|
## Settings
|
|
|
|
### 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:
|
|
|
|
```zsh
|
|
# in ~/.zshrc, before Oh My Zsh is sourced:
|
|
ZSH_DOTENV_FILE=.dotenv
|
|
```
|
|
|
|
### ZSH_DOTENV_PROMPT
|
|
|
|
Set `ZSH_DOTENV_PROMPT=false` in your zshrc file if you don't want the confirmation message.
|
|
You can also choose the `Always` option when prompted to always allow sourcing the .env file
|
|
in that directory. See the next section for more details.
|
|
|
|
### ZSH_DOTENV_ALLOWED_LIST, ZSH_DOTENV_DISALLOWED_LIST
|
|
|
|
The default behavior of the plugin is to always ask whether to source a dotenv file. There's
|
|
a **Y**es, **N**o, **A**lways and N**e**ver option. If you choose Always, the directory of the .env file
|
|
will be added to an allowed list; if you choose Never, it will be added to a disallowed list.
|
|
If a directory is found in either of those lists, the plugin won't ask for confirmation and will
|
|
instead either source the .env file or proceed without action respectively.
|
|
|
|
The allowed and disallowed lists are saved by default in `$ZSH_CACHE_DIR/dotenv-allowed.list` and
|
|
`$ZSH_CACHE_DIR/dotenv-disallowed.list` respectively. If you want to change that location,
|
|
change the `$ZSH_DOTENV_ALLOWED_LIST` and `$ZSH_DOTENV_DISALLOWED_LIST` variables, like so:
|
|
|
|
```zsh
|
|
# in ~/.zshrc, before Oh My Zsh is sourced:
|
|
ZSH_DOTENV_ALLOWED_LIST=/path/to/dotenv/allowed/list
|
|
ZSH_DOTENV_DISALLOWED_LIST=/path/to/dotenv/disallowed/list
|
|
```
|
|
|
|
The file is just a list of directories, separated by a newline character. If you want
|
|
to change your decision, just edit the file and remove the line for the directory you want to
|
|
change.
|
|
|
|
NOTE: if a directory is found in both the allowed and disallowed lists, the disallowed list
|
|
takes preference, _i.e._ the .env file will never be sourced.
|
|
|
|
## 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.
