Interface JCoreOptions

This section is about the JMAP Library startup options.

JMap library executable is available through a CDN url.

The URL is like "https://cdn.jsdelivr.net/npm/jmap-core-js@0.5.0/public/", but it depends on the version you want to use.

First you need to import our JS file in your http file, in order to load the JMap Cloud NG Core library. It's recommended to put the CDN import at the end of the body tag, like that :

...
<html>
  ...
  <body>
    ...
    <!-- !!! Insert the import at the end of the body tag !!! -->
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/"></script>
  </body>
</html>

To make the JMap Cloud NG Core library working you need to provide some required information like :

  • Your JMap Server Rest API URL
  • The project id to open
  • A valid JMap user session token, or set the JMap Cloud NG Core library to log as "anonymous"

It can be passed by setting a global JS variable named "JMAP_OPTIONS" :

<html>
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        // a valid project id
        projectId: 10,
        // a valid JMap server Rest url
        restBaseUrl: "http://my-jmap-server/services/rest/v2.0",
        session: {
          // a valid session token
          token: 2345677654
        }
        ... // other optional JMAP params
      }
    </script>
    ... your web page
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/"></script>
  </body>
</html>

Below a full example of how to start the JMap library in a web page, where parameters ngToken and ngProjectId are get from the url :

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
    <meta charset="UTF-8">
  </head>
  <body class="jmap_wrapper">
   <script type="text/javascript">
      const url = new URL(window.location.href)
      const token = url.searchParams.get("ngToken")
      let projectId = Number(url.searchParams.get("ngProjectId"))
      if (isNaN(projectId)) {
        projectId = 0
      }
      window.JMAP_OPTIONS = {
        projectId: Number(projectId),
        restBaseUrl: "http://your-jmap-server-url/services/rest/v2.0",
        token: token
      }
    </script>
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/index.js">
    </script>
  </body>
</html>

For example, you can pass this parameters like that :

  • http:// my-company/my-custom-page-using-jmap?ngToken=95423672742&ngProjectId=10.

When JMap Cloud NG Core library starts, if the JMap token "95423672742" is valid, it will automatically load the JMap project id=10, then load the map in the div id="jmap-map".

interface JCoreOptions {
    anonymous?: boolean;
    defaultBasemapId?: string;
    disableBasemaps?: boolean;

Properties

Optional anonymous

anonymous?: boolean

If the project you access can be accessed anonymously, you are not forced to pass a session token but you have to explicitly tell the JMap Cloud NG library to log as an anonymous user by setting the "anonymous" parameter like that :

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        // a valid project id
        projectId: 10,
        // a valid JMap Server Rest url
        restBaseUrl: "http://my-jmap-server/services/rest/v2.0",
        // The anonymous parameter
        anonymous: true
        ... // other optional JMAP params
      }
    </script>

    ... your web page

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

Optional defaultBasemapId

defaultBasemapId?: string

A basemap id.

If provided, will use the corresponding basemap as the default basemap.

If the id is unknown, will do nothing. To get all basemaps ids in the project, use JMap.Map.Basemap.getAllIds

Using the id "none" will use no basemap at startup.

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        // disable the default basemap
        defaultBasemapId: "none"
      }
    </script>
    ...
  </body>
</html>

Optional disableBasemaps

disableBasemaps?: boolean

If true, no basemap will be available/displayed. In JMap Cloud NG, no basemap panel will be displayed in the left panel

Optional disableProjectChange

disableProjectChange?: boolean

If true, changing project after one has been loaded will be disabled.

Optional extensions

extensions?: JCoreExtension[]

Optional extensions.

Click JCoreExtension to get details about how defining an extension.

Optional extensionsUrlOverride

extensionsUrlOverride?: JExtensionServerOverride[]

As a developer, you can override a project's extension jsUrl during development.

Ex: the extension having id="custom-extension" is set on the project. Its unique identifier is:

  • for JMap Server: serverExtensionId = "my.extention.classPath"
  • for JMap Cloud: jmapCloudExtensionUrn = "949079ff-d021-45dd-93c0-611bfcebfc2b"

Its jsUrl is "https://cdn.jsdelivr.net/npm/custom-extension@1.0.10/public/index.js"

During development, you need to be able to load your local code instead of the code located at the extension's jsUrl location.

Your local development code could for instance be available at: "https://localhost:8083/build/index.js".

In order to change the extension jsUrl dynamically, you can set your JMAP_OPTIONS.extensionsUrlOverride property like this:

For JMAp Server: [{ extensionUniqueIdentifier: "my.extention.classPath", jsUrl: "https://localhost:8083/build/index.js" }]

For JMap Cloud: [{ extensionUniqueIdentifier: "949079ff-d021-45dd-93c0-611bfcebfc2b", jsUrl: "https://localhost:8083/build/index.js" }]

Optional geolocationEnabled

geolocationEnabled?: boolean

By default the geolocation service is enabled.

But you can disable the geolocation service by setting the "geolocationEnabled" parameter to false :

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        geolocationEnabled: false
      }
    </script>
    ...
  </body>
</html>

Optional hideMainLayout

hideMainLayout?: boolean

By default NG Core provide a main layout in order to display:

  • a loader incating NG Core is loading
  • a login panel
  • a project selection panel

But you can avoid this UI by setting this option to true.

For example NG don't need NG Core minimal UI and use this option.

Optional loadProjectThumbnails

loadProjectThumbnails?: boolean

By default project thumbnails are not loaded, because they are not useful if JMap Cloud NG Core lib is used alone.

To load asynchronously project thumbnails, set startup option "loadProjectThumbnails" to true.

JMap Cloud NG Core lib will load all project thumbnails (or preview) in project objects (property "base64ImageThumbnail").

The thumbnail is stored as a base64 string image, that you can use to set an img src attribute directly.

For a project object, if thumbnail is not loaded, default value of its property "base64ImageThumbnail" is "" (empty string).

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        loadProjectThumbnails: true
      }
    </script>
    ...
  </body>
</html>

Then you will be able to get a project and use its thumbnail :

JMap.Project.getBase64ImageThumbnail() // return loaded project image, "" if no image loaded
JMap.Project.getById(3).base64ImageThumbnail // return project id=3 image, "" if no image loaded

Optional locale

locale?: string

If set to any of the locales supported by JMap, will define the default locale, bypassing browser or user-defined locale.

Supported locales can be retrieved by calling JMap.Language.getLocales

Optional map

map?: JCoreMapOptions

All map related options.

Click on JCoreMapOptions to get details.

Optional onReady

onReady?: (() => void)

Call when the JMap library is loaded

Type declaration

    • (): void

    • Returns void

Optional organizationId

organizationId?: string

The JMap Cloud organization id associated with the refresh token.

For JMap CLoud only. Only taken into account if a refresh token has been passed via the JCoreOptions.token startup option (or the equivalent hash parameter version) or if the "anonymous" option has been passed, together with a project id.

You can pass this organization id to open a session on JMap Cloud via the startup options.

A typical usage for a session opening:

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        token: "v1.MRq [.....] Rehef72YWws", // a refresh token
        organizationId: "my-organization-id"
      }
    </script>
    ...
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/"></script>
  </body>
</html>

A typical usage for a JMap Cloud public project:

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        anonymous: true,
        projectId: "my-project-id",
        organizationId: "my-organization-id"
      }
    </script>
    ...
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/"></script>
  </body>
</html>

Optional projectId

projectId?: JId

The JMap project id.

If both a project id and a project name are provided, project id will be used.

If no project name or id are set, the library will do noting, you will have a blank page.

So if you want the library to load the project automatically, you need to set the project id.

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        // a valid project id
        projectId: 12
      }
    </script>
    ...
  </body>
</html>

Optional projectName

projectName?: string

A JMap project name.

If you can prefer using the project id over the name.

If both a project id and a project name are provided, project id will be used.

If no project name or id are set, the library will do noting, you will have a blank page.

So if you want the library to load the project automatically, you need to set the project name (or id).

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        // a valid project name
        projectName: "The world"
      }
    </script>
    ...
  </body>
</html>

Optional restBaseUrl

restBaseUrl?: string

The JMap Server Rest API url.

Default value is : http://localhost:8080/services/rest/v2.0 (for test only).

If your are not testing you must provide the url of your JMap REST API :

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        ...
        // a valid JMap REST Api url
        restBaseUrl: "http://my-custom-jmap-server-url/services/rest/v2.0"
      }
    </script>
    ...
  </body>
</html>

Optional token

token?: string

The JMap user's session token.

If you don't use the library with an anonymous user (see the JCoreOptions.anonymous parameter in this section), you must provide a JMap Server session token or a JMap Cloud refresh token to the JMap library.

To get a session or refresh token, you can use the JMap Rest API on your JMap Server. See JMap.User.setToken for detailed examples on how to fetch a token through JMap's REST API.

So to start the library using the fetched token you can configure your startup options like this :

<html>
  ...
  <body>
    <script type="text/javascript">
      window.JMAP_OPTIONS = {
        token: "23558109"
      }
    </script>
    ...
    <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/"></script>
  </body>
</html>

If you don't want to make an AJAX call to the REST API, you can use the JMap library to login (JMap will make the AJAX call to the rest API). You have to wait for the lib to be loaded and the server to be ready to accept requests.

To know if the lib has been loaded you can check if the JMAp namespace exists or not. See below for an example:

<!DOCTYPE html>
  <html>
    ...
    <body class="jmap_wrapper">
      <script type="text/javascript">
        console.log("JMap", window.JMap)
        window.JMAP_OPTIONS = {
          projectId: 35,
          restBaseUrl: "https://jmap7dev.jmaponline.net/services/rest/v2.0",
          map: {
            zoom: 9.757829447748511,
            center: {
              x: -73.66415865898597,
              y: 45.53583011032552
            }
          }
        }
      </script>
      ...
      <script defer type="text/javascript" src="https://cdn.jsdelivr.net/npm/jmap-core-js@x.x.x/public/index.js"></script>
      <script>
        (function jmapLogin() {
          if (window.hasOwnProperty("JMap") && JMap.Server.isReady()) {
            JMap.User.login("jdo@company.com", "xxx")
          } else {
            console.log("Waiting for the JMap lib to be loaded ...")
            setTimeout(() => jmapLogin(), 150) // check every 150 milliseconds
          }
        })()
      </script>
    </body>
  </html>
