2 
+
3 
+Shim to load environment variables from `.env` into `ENV` in *development*.
4 
+
5 
+Storing [configuration in the environment](http://www.12factor.net/config) 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.
6 
+
7 
+But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. dotenv loads variables from a `.env` file into `ENV` when the environment is bootstrapped.
8 
+
9 
+## Installation
10 
+
11 
+### Rails
12 
+
13 
+Add this line to the top of your application's Gemfile:
14 
+
15 
+```ruby
16 
+gem 'dotenv-rails', :groups => [:development, :test]
17 
+```
18 
+
19 
+And then execute:
20 
+
21 
+```shell
22 
+$ bundle
23 
+```
24 
+
25 
+#### Note on load order
26 
+
27 
+dotenv is initialized in your Rails app during the `before_configuration` callback, which is fired when the `Application` constant is defined in `config/application.rb` with `class Application < Rails::Application`. If you need it to be initialized sooner, you can manually call `Dotenv::Railtie.load`.
28 
+
29 
+```ruby
30 
+# config/application.rb
31 
+Bundler.require(*Rails.groups)
32 
+
33 
+Dotenv::Railtie.load
34 
+
35 
+HOSTNAME = ENV['HOSTNAME']
36 
+```
37 
+
38 
+If you use gems that require environment variables to be set before they are loaded, then list `dotenv-rails` in the `Gemfile` before those other gems and require `dotenv/rails-now`.
39 
+
40 
+```ruby
41 
+gem 'dotenv-rails', :require => 'dotenv/rails-now'
42 
+gem 'gem-that-requires-env-variables'
43 
+```
44 
+
45 
+### Sinatra or Plain ol' Ruby
46 
+
47 
+Install the gem:
48 
+
49 
+```shell
50 
+$ gem install dotenv
51 
+```
52 
+
53 
+As early as possible in your application bootstrap process, load `.env`:
54 
+
55 
+```ruby
56 
+require 'dotenv'
57 
+Dotenv.load
58 
+```
59 
+
60 
+Alternatively, you can use the `dotenv` executable to launch your application:
61 
+
62 
+```shell
63 
+$ dotenv ./script.py
64 
+```
65 
+
66 
+To ensure `.env` is loaded in rake, load the tasks:
67 
+
68 
+```ruby
69 
+require 'dotenv/tasks'
70 
+
71 
+task :mytask => :dotenv do
72 
+    # things that require .env
73 
+end
74 
+```
75 
+
76 
+## Usage
77 
+
78 
+Add your application configuration to your `.env` file in the root of your project:
79 
+
80 
+```shell
81 
+S3_BUCKET=YOURS3BUCKET
82 
+SECRET_KEY=YOURSECRETKEYGOESHERE
83 
+```
84 
+
85 
+If you need multiline variables, for example private keys, you can double quote strings and use the `\n` character for newlines:
86 
+
87 
+```shell
88 
+PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\nHkVN9…\n-----END DSA PRIVATE KEY-----\n"
89 
+```
90 
+
91 
+You may also add `export` in front of each line so you can `source` the file in bash:
92 
+
93 
+```shell
94 
+export S3_BUCKET=YOURS3BUCKET
95 
+export SECRET_KEY=YOURSECRETKEYGOESHERE
96 
+```
97 
+
98 
+Whenever your application loads, these variables will be available in `ENV`:
99 
+
100 
+```ruby
101 
+config.fog_directory  = ENV['S3_BUCKET']
102 
+```
103 
+
104 
+Comments may be added to your file as such:
105 
+
106 
+```shell
107 
+# This is a comment
108 
+SECRET_KEY=YOURSECRETKEYGOESHERE # comment
109 
+SECRET_HASH="something-with-a-#-hash"
110 
+```
111 
+
112 
+Variable names may not contain the `#` symbol. Values can use the `#` if they are enclosed in quotes.
113 
+
114 
+## Multiple Rails Environments
115 
+
116 
+dotenv was originally created to load configuration variables into `ENV` in *development*. There are typically better ways to manage configuration in production environments - such as `/etc/environment` managed by [Puppet](https://github.com/puppetlabs/puppet) or [Chef](https://github.com/opscode/chef), `heroku config`, etc.
117 
+
118 
+However, some find dotenv to be a convenient way to configure Rails applications in staging and production environments, and you can do that by defining environment-specific files like `.env.production` or `.env.test`.
119 
+
120 
+You can also `.env.local` for local overrides.
121 
+
122 
+## Should I commit my .env file?
123 
+

+Credentials should only be accessible on the machines that need access to them. Never commit sensitive information to a repository that is not needed by every development machine and server.
125 
+
126 
+Personally, I prefer to commit the `.env` file with development-only settings. This makes it easy for other developers to get started on the project without compromising credentials for other environments. If you follow this advice, make sure that all the credentials for your development environment are different from your other deployments and that the development credentials do not have access to any confidential data.
