midjourney-discord-api is a library designed to connect to a Discord channel and send messages to be processed by the Midjourney bot. It utilizes the same requests as the Discord web client, allowing seamless communication with the bot. To configure the library, extract an authenticated request sent to the Midjourney bot using your web development tools.

ESM nodeJS

import Midjourney from "midjourney-discord-api";
// or

const cli = new Midjourney("interaction.txt");
const msgs = await cli.getMessages();
console.log(msgs.length + " messages visibles"); // by default get 50 messages

Token / ids extraction.

Go to network

  • Send a request to discordBot, like /settings
  • Left click on the https://discord.com/api/v9/interactions request or https://discord.com/api/v9/science.
  • Click Copy
  • Click Copy as fetch

Copy as fetch

  • Save this request in a file, that you will provide to the Midjourney constructor. (for my Test I name this file interaction.txt)

Midjourney client initialization

the Midjourney client can be initilized in 4 different ways:

new Midjourney(filename) fetch command

in this case the provided file should contains a valid NodeJS fetch command as described in the previous section.

filename can also be replace by it's content.

new Midjourney(filename) environement file

in this case the provided file should contains somthink like:

SALAI_TOKEN = your 72 char long authorization token
SERVER_ID = the serverId
CHANNEL_ID = the channelId

SERVER_ID and CHANNEL_ID can be omit, if you provide those data using Midjourney.setDiscordChannelUrl("https://discord.com/channels/1234567890/1234567890")

environement variable

in this case SALAI_TOKEN should contains you 72 char long authorization token. SERVER_ID and CHANNEL_ID should contains the serverId and channelId

SERVER_ID and CHANNEL_ID can be omit, if you provide those data using Midjourney.setDiscordChannelUrl("https://discord.com/channels/1234567890/1234567890")

new Midjourney(SALAI_TOKEN) directly provide SALAI_TOKEN

in this case a 72 char long SALAI_TOKEN token should be pass to the Midjourney constructor like: new Midjourney(SALAI_TOKEN)

then you will have to provide serverId and channelId using Midjourney.setDiscordChannelUrl("https://discord.com/channels/1234567890/1234567890")

Usage

Here are some examples of how to use the Midjourney class:

Describe URL

import Midjourney from "midjourney-discord-api";
// or
// import Midjourney from "@u4/midjourney";

const client = new Midjourney("interaction.txt");
await client.connectWs(); // Used Websocket to boost detection. (experiental)
const prompts: string[] = await client.describeUrl(
  "https://cdn.midjourney.com/95e2c8fd-255c-4982-9065-83051143570c/0_0_640_N.webp",
  // add optional progress function (percent) => void
);
console.log("reversed prompt: ", prompts);

Imagine

import Midjourney from "midjourney-discord-api";
// or
// import Midjourney from "@u4/midjourney";

const client = new Midjourney("interaction.txt");
await client.connectWs(); // Used Websocket to boost detection. (experiental)
const msg = await client.imagine(
  "A photo of an astronaut riding a horse",
  // add optional progress function (percent) => void
);
console.log("you find your result here: ", msg.attachments[0].url);

Upscale

// Upscale the first none upscaled images in chat, searching from the newest to the oldest images
import Midjourney from "midjourney-discord-api";
// or
// import Midjourney from "@u4/midjourney";

// Variant the last image available in chat
const client = new Midjourney("interaction.txt");
await client.connectWs(); // Used Websocket to boost detection. (experiental)
const msgs = await client.getMessages();
main:
for (const msg of msgs) {
  if (!msg.canVariant()) {
    continue;
  }
  for (let i = 1; i <= 4; i++) {
    const v = msg.canVariant(i)
    if (v) {
      console.log(`Variant image ${v.custom_id} from ${msg.id}: ${msg.prompt?.prompt}`);
      const result = await msg.variant(i);
      await result.download(0, "images");
      break main;
    }
  }
}

Variant

// Variant the last image available in chat
const client = new Midjourney("interaction.txt");
await client.connectWs(); // Used Websocket to boost detection. (experiental)
const msgs = await client.getMessages();
main:
for (const msg of msgs) {
  if (!msg.canVariant()) {
    continue;
  }
  for (let i = 1; i <= 4; i++) {
    const v = msg.canVariant(i)
    if (v) {
      console.log(`Variant image ${v.custom_id} from ${msg.id}: ${msg.prompt?.prompt}`);
      const result = await msg.variant(i);
      await result.download(0, "images");
      break main;
    }
  }
}

Reroll

import Midjourney from "midjourney-discord-api";
// or
// import Midjourney from "@u4/midjourney";

const client = new Midjourney("interaction.txt");
await client.connectWs(); // Used Websocket to boost detection. (experiental)
const msg = await client.imagine(
  "A photo of an astronaut riding a horse",
  // add optional progress function (percent) => void
);
if (msg.canReroll()) {
  const result = msg.reroll();
  console.log(`upscale V2 Ready from`, result.attachments[0].url);
}
