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/` | 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) | | `heartbeatInterval` | `5000` | socket.io heartbeat interval | | `heartbeatTimeout` | `10000` | socket.io heartbeat timeout | | `documentMaxLength` | `100000` | note max length | ## CodiMD paths stuff these are rarely used for various reasons. | variables | example values | description | | --------- | ------ | ----------- | | `defaultNotePath` | `./public/default.md` | default note file path1, empty notes will be created with this template. | | `dhParamPath` | `./cert/dhparam.pem` | SSL dhparam path1 (only need when you set `useSSL`) | | `sslCAPath` | `['./cert/COMODORSAAddTrustCA.crt']` | SSL ca chain1 (only need when you set `useSSL`) | | `sslCertPath` | `./cert/codimd_io.crt` | SSL cert path1 (only need when you set `useSSL`) | | `sslKeyPath` | `./cert/client.key` | SSL key path1 (only need when you set `useSSL`) | | `tmpPath` | `./tmp/` | temp directory path1 | | `docsPath` | `./public/docs` | docs directory path1 | | `viewPath` | `./public/views` | template directory path1 | | `uploadsPath` | `./public/uploads` | uploads directory1 - needs to be persistent when you use imageUploadType `filesystem` | ## CodiMD Location | variables | example values | description | | --------- | ------ | ----------- | | `domain` | `localhost` | domain name | | `urlPath` | `codimd` | sub URL path, like `www.example.com/` | | `host` | `localhost` | interface/ip to listen on | | `port` | `80` | port to listen on | | `path` | `/var/run/codimd.sock` | path to UNIX domain socket to listen on (if specified, `host` and `port` are ignored) | | `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 Gravatar as profile picture source on your instance | | `useCDN` | `true` or `false` | set to use CDN resources or not (default is `true`) | ## Users and Privileges | variables | example values | description | | --------- | ------ | ----------- | | `allowAnonymous` | `true` or `false` | Set to allow anonymous usage (default is `true`). | | `allowAnonymousEdits` | `true` or `false` | If `allowAnonymous` is `true`: allow users to select `freely` permission, allowing guests to edit existing notes (default is `false`). | | `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 users). | | `sessionName` | `connect.sid` | Cookie session name. | | `sessionLife` | `14 * 24 * 60 * 60 * 1000` | 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 Most of these have never been documented for the config.json, feel free to expand these ### Email (local account) | variables | example values | description | | --------- | ------ | ----------- | | `email` | `true` or `false` | Set to allow email sign-in. The default is `true`. | | `allowEmailRegister` | `true` or `false` | Set to allow registration of new accounts using an email address. If set to `false`, you can still create accounts using the command line - see `bin/manage_users` for details. This setting has no effect if `email` is `false`. The default for `allowEmailRegister` is `true`. | ### Dropbox Login ### Facebook Login ### GitHub Login ### GitLab Login ### Google Login ### LDAP Login ### Mattermost Login ### OAuth2 Login | variables | example values | description | | --------- | ------ | ----------- | | `oauth2` | `{baseURL: ..., userProfileURL: ..., userProfileUsernameAttr: ..., userProfileDisplayNameAttr: ..., userProfileEmailAttr: ..., tokenURL: ..., authorizationURL: ..., clientID: ..., clientSecret: ...}` | An object detailing your OAuth2 provider.

Also check out our [Minio Image Upload Guide](guides/minio-image-upload.md) | ### Lutim | variables | example values | description | | --------- | ------ | ----------- | |`lutim`| `{"url": "YOUR_LUTIM_URL"}`| When `imageUploadType` is set to `lutim`, you can setup the lutim url| 1: relative paths are based on CodiMD's base directory
