Config

esmBot uses environment variables for configuration. To make managing them easier, a .env file is included with the bot and can be used to load the variables on bot startup.

Here's an overview of the environment variables required to run the bot:

  • 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 at 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/. You can also set this to dummy to make the bot not use a database at all.
  • 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. Note that servers can set their own individual prefixes via the prefix command.

Here's an overview of the 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.
  • DBL: An API token from Top.gg. Unnecessary for most users since Top.gg tends to ban forks of bots like esmBot from their list.
  • TENOR: An API token from Tenor. 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-compatible metrics on.
  • API: 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 servers.json, or "azure" to use the Azure Functions-based API.
  • AZURE_URL: Your Azure webhook URL. Only applies if API is set to "azure".
  • AZURE_PASS: An optional password used for Azure requests. Only applies if API is set to "azure".
