So i'm making a fetch request from react to express and the api url requires params but I want the last bit of the url to be dynamic. How would I send a param from react to the api url in express? Heres the code

react

const [dynamic, setDynamic] = useState("somevalue")



  useEffect(() => {

    async function fetchData() { 

        const response = await fetch("/web")

        const data = await response.json()

        console.log(data)

    }

    fetchData()

  }, [dynamic])

express.js

app.get("/web", async (req, res) => {

    const response = await fetch("https://alexa.com/api?Action=urlInfo&Url=")

      const data = await response.json()

      res.json(data)

})

Basically, I would like the dynamic state value to be injected into the end of the URL in express.

Something like

react

const [dynamic, setDynamic] = useState("somevalue")



    async function fetchData() { 

        const response = await fetch("/web" + dynamic)

        const data = await response.json()

        console.log(data)

      }

Then in express when the API is called the URL changes to

const response = await fetch("https://alexa.com/api?Action=urlInfo&Url=somevalue")

How can I go about achieving this?
