Access node in Adobe CEP extension

Question

Adobe allows usage of Node.js in CEP extensions, if activated through the manifest.xml. I followed all steps and tried to reproduce this example from Davide Barranca: http://www.davidebarranca.com/2017/10/html-panel-tips-25-cc-2018-survival-guide/#comment-202966

But cep_node just stays undefined, whatever I do.

Answer 1

Already solved it myself through the manifest. Make sure that 1. The tag and have the attribute Version="7.0" 2. Make sure the required tag with its child is within the tag. In some Adobe example it's wrong.

Answer 2

For anyone looking for more detailed information on working with Node.js in a CEP extension, a frequently overlooked step is to enable Node.js in the manifest.xml file:

    <CEFCommandLine>
      <Parameter>--enable-nodejs</Parameter>
    </CEFCommandLine>

A full manifest depends on your desired setup and can get long, but here's one example.

A few resources to learn more:

1. The new CEP Getting Started guide covers writing a basic manifest.
   • Even if you're using CEP 8.0, you'll need to have the Version="7.0" attribute for the ExtensionManifest and RequiredRuntime elements.
   • See the sample manifest in this Getting Started guide.
2. The CEP Cookbook has some deeper info on writing a manifest file.
3. We've recently updated the samples in the CEP Samples repo.
   • This sample will give you some further insight into how to use Node.js.
4. We've got a blog post up that walks you through a more complex setup with Node.js.
