# ServerSideFunction

### Server Functions

Server Functions (or Server Side Functions) are functions that are executed on the server, instead of the javascript engine in the browser. Basically they are webservices, that respond to a post call and that accept the parameters in a specific pattern, defined by the brixxbox.

You can use the api function serverFunction to call a Server Function

### Example Usages

To call a function and get the response object:

```javascript
let functionResponse = brixxApi.serverFunction("myFunction", {
   name: "Hallo"
});
console.log(functionResponse.functionResult);
```

\
To get an example payload based on the current app state:

```javascript
let functionResponse = brixxApi.serverFunction("myFunction", {
   name: "Hallo"
},{
   payload: true
});
console.log(functionResponse.functionResult);
```

To get an example postman collection including the payload of the current app:

```javascript
let functionResponse = brixxApi.serverFunction("myFunction", {
   name: "Hallo"
},{
   postman: true
});
console.log(functionResponse.functionResult);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://brixxbox.gitbook.io/brixxbox-documentation/configuration/apps/serversidefunction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
