## Getting Started

### Express

`pnpm install @queuedash/api`

```typescript
import express from "express";
import Bull from "bull";
import { createQueueDashExpressMiddleware } from "@queuedash/api";

const app = express();

const reportQueue = new Bull("report-queue");

app.use(
  "/queuedash",
  createQueueDashExpressMiddleware({
    ctx: {
      queues: [
        {
          queue: reportQueue,
          displayName: "Reports",
          type: "bull" as const,
        },
      ],
    },
  }),
);

app.listen(3000, () => {
  console.log("Listening on port 3000");
  console.log("Visit http://localhost:3000/queuedash");
});
```

### Next.js

`pnpm install @queuedash/api @queuedash/ui`

#### App Router

```typescript jsx
// app/admin/queuedash/[[...slug]]/page.tsx
"use client";

import { QueueDashApp } from "@queuedash/ui";
import "@queuedash/ui/dist/styles.css";

function getBaseUrl() {
  if (process.env.VERCEL_URL) {
    return `https://${process.env.VERCEL_URL}/api/queuedash`;
  }

  return `http://localhost:${process.env.PORT ?? 3000}/api/queuedash`;
}

export default function QueueDashPages() {
  return <QueueDashApp apiUrl={getBaseUrl()} basename="/admin/queuedash" />;
}
```

```typescript jsx
// app/api/queuedash/[...trpc]/route.ts
import { fetchRequestHandler } from "@trpc/server/adapters/fetch";
import { appRouter } from "@queuedash/api";

const reportQueue = new Bull("report-queue");

function handler(req: Request) {
  return fetchRequestHandler({
    endpoint: "/api/queuedash",
    req,
    router: appRouter,
    allowBatching: true,
    createContext: () => ({
    queues: [
      {
        queue: reportQueue,
        displayName: "Reports",
        type: "bull" as const,
      },
    ],
  });
}

export { handler as GET, handler as POST };
```

#### Pages Router

```typescript jsx
// pages/admin/queuedash/[[...slug]].tsx
import { QueueDashApp } from "@queuedash/ui";

function getBaseUrl() {
  if (process.env.VERCEL_URL) {
    return `https://${process.env.VERCEL_URL}/api/queuedash`;
  }

  return `http://localhost:${process.env.PORT ?? 3000}/api/queuedash`;
}

const QueueDashPages = () => {
  return <QueueDashApp apiUrl={getBaseUrl()} basename="/admin/queuedash" />;
};

export default QueueDashPages;
```

```typescript jsx
// pages/api/queuedash/[trpc].ts
import * as trpcNext from "@trpc/server/adapters/next";
import { appRouter } from "@queuedash/api";

const reportQueue = new Bull("report-queue");

export default trpcNext.createNextApiHandler({
  router: appRouter,
  batching: {
    enabled: true,
  },
  createContext: () => ({
    queues: [
      {
        queue: reportQueue,
        displayName: "Reports",
        type: "bull" as const,
      },
    ],
  }),
});
```

### Docker

The fastest way to get started is using the official Docker image:

```bash
docker run -p 3000:3000 \
  -e QUEUES_CONFIG_JSON='{"queues":[{"name":"my-queue","displayName":"My Queue","type":"bullmq","connectionUrl":"redis://localhost:6379"}]}' \
  ghcr.io/alexbudure/queuedash:latest
```

Then visit http://localhost:3000

#### Environment Variables

- `QUEUES_CONFIG_JSON` - Optional if `QUEUES_CONFIG_FILE_PATH` is set. JSON string containing queue configuration.
- `QUEUES_CONFIG_FILE_PATH` - Optional if `QUEUES_CONFIG_JSON` is set. Path to a JSON file containing queue configuration.

Example configuration:

```json
{
  "queues": [
    {
      "name": "cancellation-follow-ups",
      "displayName": "Cancellation follow-ups",
      "type": "bullmq",
      "connectionUrl": "redis://localhost:6379"
    },
    {
      "name": "clustered-reports",
      "displayName": "Clustered Reports",
      "type": "bullmq",
      "clusterNodes": [
        { "host": "redis-cluster-0", "port": 6379 },
        { "host": "redis-cluster-1", "port": 6379 },
        { "host": "redis-cluster-2", "port": 6379 }
      ]
    },
    {
      "name": "email-queue",
      "displayName": "Email Queue",
      "type": "bull",
      "connectionUrl": "redis://localhost:6379"
    }
  ]
}
```

For `bullmq` queues, provide either `connectionUrl` (single-node Redis) or `clusterNodes` (Redis Cluster). `clusterNodes` is not supported for `bull` or `bee`.

Supported queue types: `bull`, `bullmq`, `bee`, `groupmq`

See the [./examples](./examples) folder for more.
