# Start the JMap NG Core library

You can start JMap NG Core in a div of your website, or as a full page application.

## Import the library from CDN

To use the JMap NG Core library, simply import the JMap NG Core Javascript library from our CDN link.

```html
<script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@7_Kathmandu_HF3"></script>
```

Make sure the version of the library matches the version of your JMap Server instance.

## Set library options

You have to specify options to the library:

```javascript
window.JMAP_OPTIONS = {
  projectId: 1,
  restBaseUrl: "https://jmapdoc.jmaponline.net/services/rest/v2.0",
  anonymous: true,
  map: {
    containerId: "my-custom-map",
    zoom: 9.757829447748511,
    center: {
      x: -73.60243569463414,
      y: 45.504533166207324
    },
    scaleControlVisible: true,
    scaleControlPosition: "top-right"
  }
}
```

## Display the map full page

Instead of running JMap NG Core inside a DIV, you can start it directly in the body of the web page for a full page experience.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.jmapcloud.io/en/jmap-ng/jmap-ng-developer-documentation/examples/start-the-jmap-ng-core-library.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.
