Manifest - Nacl Modules

One or more mappings from MIME types to the Native Client module that handles each type. For example, the bold code in the following snippet registers a Native Client module as the content handler for the OpenOffice spreadsheet MIME type.

{
  "name": "Native Client OpenOffice Spreadsheet Viewer",
  "version": "0.1",
  "description": "Open OpenOffice spreadsheets, right in your browser.",
  "nacl_modules": [{
    "path": "OpenOfficeViewer.nmf",
    "mime_type": "application/vnd.oasis.opendocument.spreadsheet"
  }]
}

The value of "path" is the location of a Native Client manifest (a .nmf file) within the extension directory. For more information on Native Client and .nmf files, see the Native Client Technical Overview.

Each MIME type can be associated with only one .nmf file, but a single .nmf file might handle multiple MIME types. The following example shows an extension with two .nmf files that handle three MIME types.

{
  "name": "Spreadsheet Viewer",
  "version": "0.1",
  "description": "Open OpenOffice and Excel spreadsheets, right in your browser.",
  "nacl_modules": [{
    "path": "OpenOfficeViewer.nmf",
    "mime_type": "application/vnd.oasis.opendocument.spreadsheet"
  },
  {
    "path": "OpenOfficeViewer.nmf",
    "mime_type": "application/vnd.oasis.opendocument.spreadsheet-template"
  },
  {
    "path": "ExcelViewer.nmf",
    "mime_type": "application/excel"
  }]
}
