File system storage

[awmartin]

Motivation

As an author self-deploying Doctoral, I want the ability to use the file system, instead of a running database, for storage, because I want to use a syncing service like Dropbox to manage backups, or I don't want the complexity of running such a database alongside the Express backend.

Design

Provide a way to switch to the file system when initializing the server and specify a path, either in a config file or in the command to launch the server.

Store the table of contents in a json file, contents.json, for now. Each document should have its own JSON file.

Acceptance

• Given the express server code,
• when I start the server and specify the folder to store my data
• and I start the front-end and create/edit documents
• then I observe the appropriate files (see Design above) in the folder I specified that contain the contents of my documents.
