The following example activity script posts a message to a Discord channel every time it’s triggered. To use it, follow these steps:
  1. In your Discord administrative interface, create a new Discord webhook. Give it a name and specify the channel where it should post messages. Copy the URL for the webhook.
  2. Replace DISCORD_URL in the following script with your webhook URL.
  3. Paste the code into a .js file.
  4. Add it as a new script integration. Specify which events should trigger it using the --events flag. Optionally specify environments with the --environments flag.
Now, any activities that meet the events/environment criteria you specified are reported to Discord. Once you have it working, you’re free to modify the code below as desired. For more on the message format, see the Discord webhook API reference. 
/**
 * Sends a message to Discord.
 *
 * To control what events trigger it, use the --events switch in
 * the Upsun CLI.
 *
 * @param {string} title
 *   The title of the message block to send.
 * @param {string} message
 *   The message body to send.
 */
function sendDiscordMessage(title, message) {
  const url = DISCORD_URL;

  const messageTitle =
    title + (new Date().getDay() === 5) ? " (On a Friday! :calendar:)" : "";

  const body = {
    content: messageTitle,
    embeds: [
      {
        description: message,
      },
    ],
  };

  const resp = fetch(url, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify(body),
  });

  if (!resp.ok) {
    console.log("Sending Discord message failed: " + resp.body.text());
  }
}

sendDiscordMessage(activity.text, activity.log);
Common properties you may want to send to Discord (in the last line of the script) include:
  • activity.text: A brief, one-line statement of what happened.
  • activity.log: The complete build and deploy log output, as it would be seen in the Console log screen.
For more properties, see the activity reference.
