Configuration Using Config file
You can choose to configure CodiMD with either a config file or with
environment variables. The config file is processed
in lib/config/index.js - so this is the first
place to look if anything is missing not obvious from this document. The
default values are defined in lib/config/default.js,
in case you wonder if you even need to override it.
Environment variables take precedence over configurations from the config files.
To get started, it is a good idea to take the config.json.example and copy it
to config.json before filling in your own details.

Configures Content Security Policy. Directives are passed to Helmet - see their documentation for more information on the format. Some defaults are added to the configured values so that the application doesn't break. To disable this behaviour, set addDefaults to false.

To change this behaviour, set upgradeInsecureRequests to either true or false. |
