Source: https://github.com/darkvisitors/node-sdk/blob/main/README.md

Example of setting up an Express application to automatically track all incoming requests using Dark Visitors SDK middleware. It initializes the SDK and applies a middleware function to call `trackVisit` for every request.

```TypeScript
import express from "express"
import { DarkVisitors } from "@darkvisitors/sdk"

const app = express()
const darkVisitors = new DarkVisitors("your-access-token")

app.use((req, res, next) => {
    darkVisitors.trackVisit(req)
    next()
})

app.get("/", (req, res) => {
    res.send("Hello, world!")
})

app.listen(3000, () => console.log("Server running on port 3000"))
```
