Hide your sensitive node.js bits in plain sight.
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
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
decrypt scripts, such as in the following:
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
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
- Compare timestamps to make sure decrypted file is up to date.
