## Configuration
Theres two main ways to configure your CodiMD instance:
[Config file](docs/configuration-config-file.md) or
[environment variables](docs/configuration-env-vars.md). You can choose what
works best for you.

Configuration Using Config file
===
You can choose to configure CodiMD with either a config file or with
[environment variables](configuration-env-vars.md). The config file is processed
in [`lib/config/index.js`](../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`](../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.
## Node.JS
| variables | example values | description |
| --------- | ------ | ----------- |
| `debug` | `true` or `false` | set debug mode, show more logs |
## CodiMD basics
| variables | example values | description |
| --------- | ------ | ----------- |
| `allowPDFExport` | `true` | Whether or not PDF export is offered. |
| `db` | `{ "dialect": "sqlite", "storage": "./db.codimd.sqlite" }` | set the db configs, [see more here](http://sequelize.readthedocs.org/en/latest/api/sequelize/) |
| `dbURL` | `mysql://localhost:3306/database` | Set the db in URL style. If set, then the relevant `db` config entries will be overridden. |
| `forbiddenNoteIDs` | `['robots.txt']` | disallow creation of notes, even if `allowFreeUrl` is `true` |
| `loglevel` | `info` | Defines what kind of logs are provided to stdout. Available options: `debug`, `verbose`, `info`, `warn`, `error` |
| `imageUploadType` | `imgur`, `s3`, `minio`, `azure`, `lutim` or `filesystem`(default) | Where to upload images. For S3, see our Image Upload Guides for [S3](guides/s3-image-upload.md) or [MinIO](guides/minio-image-upload.md)|
| `sourceURL` | `https://github.com/codimd/server/tree/<current commit>` | Provides the link to the source code of CodiMD on the entry page (Please, make sure you change this when you run a modified version) |
| `staticCacheTime` | `1 * 24 * 60 * 60 * 1000` | static file cache time |
| `tooBusyLag` | `70` | CPU time for one event loop tick until node throttles connections. (milliseconds) |

## CodiMD paths stuff
these are rarely used for various reasons.
| variables | example values | description |
| --------- | ------ | ----------- |
| `defaultNotePath` | `./public/default.md` | default note file path<sup>1</sup>, empty notes will be created with this template. |
| `dhParamPath` | `./cert/dhparam.pem` | SSL dhparam path<sup>1</sup> (only need when you set `useSSL`) |
| `sslCAPath` | `['./cert/COMODORSAAddTrustCA.crt']` | SSL ca chain<sup>1</sup> (only need when you set `useSSL`) |
| `sslCertPath` | `./cert/codimd_io.crt` | SSL cert path<sup>1</sup> (only need when you set `useSSL`) |
| `sslKeyPath` | `./cert/client.key` | SSL key path<sup>1</sup> (only need when you set `useSSL`) |

| `docsPath` | `./public/docs` | docs directory path<sup>1</sup> |
| `viewPath` | `./public/views` | template directory path<sup>1</sup> |
| `uploadsPath` | `./public/uploads` | uploads directory<sup>1</sup> - needs to be persistent when you use imageUploadType `filesystem` |
## CodiMD Location

| --------- | ------ | ----------- |
| `domain` | `localhost` | domain name |
| `urlPath` | `codimd` | sub URL path, like `www.example.com/<urlpath>` |

| `protocolUseSSL` | `true` or `false` | set to use SSL protocol for resources path (only applied when domain is set) |
| `useSSL` | `true` or `false` | set to use SSL server (if `true`, will auto turn on `protocolUseSSL`) |
| `urlAddPort` | `true` or `false` | set to add port on callback URL (ports `80` or `443` won't be applied) (only applied when domain is set) |
| `allowOrigin` | `['localhost']` | domain name whitelist |
## CSP and HSTS
| variables | example values | description |
| --------- | ------ | ----------- |
| `hsts` | `{"enable": true, "maxAgeSeconds": 31536000, "includeSubdomains": true, "preload": true}` | [HSTS](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) options to use with HTTPS (default is the example value, max age is a year) |
| `csp` | `{"enable": true, "directives": {"scriptSrc": "trustworthy-scripts.example.com"}, "upgradeInsecureRequests": "auto", "addDefaults": true}` | Configures [Content Security Policy](https://helmetjs.github.io/docs/csp/). Directives are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) 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`. Further, if `usecdn` is on, some CDN locations are allowed too. By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set `upgradeInsecureRequests` to either `true` or `false`. |
## Privacy and External Requests
| variables | example values | description |
| --------- | ------ | ----------- |
| `allowGravatar` | `true` or `false` | set to `false` to disable [Libravatar](https://www.libravatar.org/) as profile picture source on your instance. Libravatar is a federated open-source alternative to Gravatar. |

| `allowFreeURL` | `true` or `false` | Set to allow new note creation by accessing a nonexistent note URL. This is the behavior familiar from [Etherpad](https://github.com/ether/etherpad-lite). |
| `defaultPermission` | `freely`, `editable`, `limited`, `locked`, `protected` or `private` | Set notes default permission (only applied on signed-in users). |
| `sessionName` | `connect.sid` | Cookie session name. |
| `sessionLife` | `14 * 24 * 60 * 60 * 1000` (14 days) | Cookie session life time in milliseconds. |
| `sessionSecret` | `secret` | Cookie session secret. If none is set, one will randomly generated on each startup, meaning all your users will be logged out. |
## Login methods
### Email (local account)

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.

Configuration
===
You can choose to configure CodiMD 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`](../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.
- The config file is processed in [`lib/config/index.js`](../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`](../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.
## Node.JS

Directives are passed to Helmet - see [their documentation](https://helmetjs.github.io/docs/csp/) 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`. Further, if `usecdn` is on, some CDN locations are allowed too. By default (`auto`), insecure (HTTP) requests are upgraded to HTTPS via CSP if `useSSL` is on. To change this behaviour, set `upgradeInsecureRequests` to either `true` or `false`. |
