esmBot uses a mix of environment variables and JSON for configuration.
## Environment Variables (.env)
To make managing environment variables easier, an example `.env` file is included with the bot at `.env.example` and can be used to load the variables on startup.
### Required
-`NODE_ENV`: Used for tuning the bot to different environments. If you don't know what to set it to, leave it as is.
-`TOKEN`: Your bot's token. You can find this [here](https://discord.com/developers/applications) under your application's Bot tab.
-`DB`: The database connection string. By default the `sqlite` and `postgresql` protocols are available, but this can be expanded by putting proper DB driver scripts into `utils/database/`.
-`OWNER`: Your Discord user ID. This is used for granting yourself access to certain management commands. Adding multiple users is supported by separating the IDs with a comma; however, this is not recommended for security purposes.
-`PREFIX`: The bot's default command prefix for classic commands. Note that servers can set their own individual prefixes via the `prefix` command.
### Optional
These variables that are not necessarily required for the bot to run, but can greatly enhance its functionality:
-`STAYVC`: Set this to true if you want the bot to stay in voice chat after playing music/a sound effect. You can make it leave by using the stop command.
-`TENOR`: An API token from [Tenor](https://tenor.com/gifapi). This is required for using GIFs from Tenor.
-`OUTPUT`: A directory to output the help documentation in Markdown format to. It's recommended to set this to a directory being served by a web server.
-`TEMPDIR`: A directory that will store generated images larger than 8MB. It's recommended to set this to a directory being served by a web server.
-`TMP_DOMAIN`: The root domain/directory that the images larger than 8MB are stored at. Example: `https://projectlounge.pw/tmp`
-`THRESHOLD`: A filesize threshold that the bot will start deleting old files in `TEMPDIR` at.
-`METRICS`: The HTTP port to serve [Prometheus](https://prometheus.io/)-compatible metrics on.
-`API_TYPE`: Set this to "none" if you want to process all images locally. Alternatively, set it to "ws" to use an image API server specified in the `image` block of `config/servers.json`.
-`ADMIN_SERVER`: A Discord server/guild ID to limit owner-only commands such as eval to.
## JSON
The JSON-based configuration files are located in `config/`.
### commands.json
```js

"classic": false, // Enable/disable "classic" (prefixed) commands, note that classic commands in direct messages will still work

"blacklist": [
// Names of commands that you don't want the bot to load
]
}
```
### messages.json
```js
