Configuration¶
You can choose to configure HedgeDoc with either a config file or with environment variables.
Environment variables take precedence over configurations from the config files. They generally start with CMD_ for our own options, but we also list node-specific options you can configure this way.
- Environment variables are processed in
lib/config/environment.js- so this is the first place to look if anything is missing not obvious from this document. The default values are defined inlib/config/default.js, in case you wonder if you even need to override it.
- 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 inlib/config/default.js, in case you wonder if you even need to override it. To get started, it is a good idea to take theconfig.json.exampleand copy it toconfig.jsonbefore filling in your own details.
Note: Due to the rename process we renamed all HMD_-prefix variables to be CMD_-prefixed. The old ones continue to work.
