# 06 - Get one item

In this module, we'll write a GET request that grabs a single item from the database for a specific user.

## CODE

Add the following method to the `03-auth-test.js` file:

```javascript
/***************************************
 * GET ITEM BY USER
*************************************/
function getOneByUser() {
    let postIdNumber = document.getElementById("getNumber").value; //1

    const fetch_url = `http://localhost:3000/authtest/${postIdNumber}` //2
    const accessToken = localStorage.getItem('SessionToken')

    const response = fetch(fetch_url, {
        method: 'GET',
        headers: {
            'Content-Type': 'application/json',
            'Authorization': accessToken
        }
    })
        .then(response => {
            return response.json();
        })
        .then(function (response) {
            console.log(response); 
            var myItem = document.getElementById('getItemValue'); //3
            myItem.innerHTML = response.authtestdata; //4
        })
}
```

## Analysis

1. We get the `postIdNumber` provided in the `getNumber` field. Because we are making an authenticated request, this `id` has to exist in the database,  as well as match the `user.id` from the database for the user that you are using currently logged in as.
2. We pass the `postIdNumber` into the url with a template literal.
3. We target an element called `getItemValue`. It's a `label` tag.
4. We set the value of the label to the value of `response.authtestdata`. This means that the data will be populated in the label when the DOM loads.

## Test

1. Go ahead and run the app.&#x20;
2. Click the `Get Single Item` button after putting in the `id` from the previous module.&#x20;
3.  You should see the following:

4. Notice that we have pulled the single item from the server. In this case, the item has the id of `10`.&#x20;
5. Not only did we print to the console, we added the data pulled from the server to the DOM in the `<label>` element on step 11 (GET Single Item).
