Configuration Using Environment variables
|
|
===
|
|
|
|
You can choose to configure CodiMD with either a
|
|
[config file](configuration-config-file.md) or with environment variables.
|
|
Environment variables are processed in
|
|
[`lib/config/environment.js`](../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`](../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.
|
|
They generally start with `CMD_` for our own options, but we also list
|
|
node-specific options you can configure this way.
|
|
|
|
|
|
## Node.JS
|
|
|
|
| variable | example value | description |
|

| `NODE_ENV` | `production` or `development` | set current environment (will apply corresponding settings in the `config.json`) |
|
|
| `DEBUG` | `true` or `false` | set debug mode; show more logs |
|
|
|
