Configuration - HedgeDoc
Skip to content
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 in
lib/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 in
lib/config/default.js
, in case you wonder
if you even need to override it. 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.
Note:
Due to the rename process we renamed all
HMD_
-prefix variables to be
CMD_
-prefixed. The old ones continue
to work.
