config-leaf helps you hide your sensitive node.js bits in plain sight. It is based on John Resig's post, Keeping Passwords in Source Control.
The idea is that the configuration of deployed apps can be managed in version control for transparency and ease of rollback. But, since configuration often contains sensitive information like passwords, it shouldn't be kept in plaintext. This is where config-leaf comes in, by letting you encrypt your config in development, check it in, and then decrypt it in production or other dev environments.
Let's say that we have a node.js project with some sensitive configuration information, kept in a file called config.json.
First, install this library as a dependency of the project:
npm install config-leaf --save
Then, make sure that you add this file to .gitignore (or appropriate ignore file depending on your version control system) to make sure it never gets checked in:
echo config.json >> .gitignore
Finally, edit your package.json to add the encrypt and decrypt scripts, such as in the following:
{
"name": "my-project",
"version": "0.0.1",
"scripts": {
...
"encrypt": "encrypt config.json config.json.cast5",
"decrypt": "decrypt config.json.cast5 config.json"
}
}Here, the encrypt script will encrypt the config.json file as config.json.cast5, and the decrypt script will decrypt the config.json.cast5 file as config.json. In both cases, the name of the encrypted file can be chosen arbitrarily.
Once config-leaf is installed and configured, run the encrypt command every time you update your configuration, and enter the password when prompted.
npm run encrypt
This saves the encrypted file according to the name you set in your package.json.
After checking the file in, use the decrypt command in production or other dev environments, and enter the password when prompted.
npm run decrypt
Again, this saves the decrypted file according to the name you set in your package.json.
- Compare timestamps to make sure decrypted file is up to date.
