Use the versions operation to retrieve the list of Node.js versions available on the server.

Request Packet Structure

The request XML packet retrieving the list of Node.js versions available on the server includes the versions operation node:

<packet>
  <extension>
    <call>
      <nodejs>
        <versions/>
      </nodejs>
    </call>
  </extension>
</packet>

Response Packet Structure

The output XML packet is structured as follows:

<?xml version="1.0" encoding="UTF-8"?>
<packet version="1.6.8.0">
  <extension>
    <call>
      <result>
        <status>ok</status>
        <nodejs>
          <versions>
            <version>
              <enabled>...</enabled>
              <version>...</version>
              <path>...</path>
            </version>
            ...
            <version>
              <enabled>...</enabled>
              <version>...</version>
              <path>...</path>
            </version>
         <versions>
        </nodejs>
      </result>
    </call>
  </extension>
</packet>

The result node is required. It wraps the response received from the server. This node contains the following nodes:

• The status node is required. It specifies the execution status of the enable operation. Data type: result_status. Allowed values: ok | error.
• The errcode node is optional. It is used to return the error code when the enable operation fails. Data type: unsignedInt.
• The errtext node is optional. It is used to return the error message if the enable operation fails. Data type: string.
• The nodejs node is optional. It is present if the operation was completed successfully and contains the following nodes:
  • The versions node contains one or more version nodes containing information about a particular Node.js version. Each version node contains the following nodes:
    • The enabled node is required. It specifies if the version is enabled. Data type: boolean.
    • The version node is required. It specifies the version number. Data type: string.
    • The path node is required. It specifies the path to the Node.js version. Data type: string.

Samples

This package retrieves information about the Node.js versions available on the server:

<packet>
  <extension>
    <call>
      <nodejs>
        <versions/>
      </nodejs>
    </call>
  </extension>

<?xml version="1.0" encoding="UTF-8"?>
<packet version="1.6.8.0">
  <extension>
    <call>
      <result>
        <status>ok</status>

            <version>
              <enabled>true</enabled>
