Building extensions #2: Creating extensions for Zoho Projects using a CLI

In our previous post, we noted the two ways to create extensions for Zoho Projects— using the cloud editor and using the command line interface (CLI). We also shared how to create an extension using the Sigma cloud editor. In this post, we'll take a closer look at creating an extension using the CLI.

You'll learn how to create an extension project template with the CLI, test it, upload the zipped project while creating an extension, and then edit or change it. Let's go over each of these steps in detail.

Building an extension project using the CLI
  • To create an extension project, we must first set up the development environment, which involves:
➤ Downloading Node.js: Node.js acts as the base platform as well as the JavaScript environment in which the JavaScript code is executed.
➤ Installing ZET CLI: Zoho offers a command line interface called Zoho Extension Toolkit (ZET) which enables you to build, test, and pack your extension project.
Please follow the steps in this link to download Node.js and install ZET CLI.
  • Once the development environment is ready, use the basic ZET commands to create, validate, pack, and test your extension project.
zet init: Create a new project and add the necessary folder structure and resources
zet validate: Validate the entire project
zet pack: Pack the project to get a zipped file that will later be associated as the connected app
zet run: Run the internal Zoho server to test the project locally
Now, let's use these commands to create and manage an extension project.
  • First, use the zet init command. Select Zoho Projects as the Zoho service from the dropdown list.

  • Enter a name for the extension. An extension with the directory structure required for a sample Zoho Projects extension is created automatically.

  • This directory structure contains an app folder and a plugin-manifest.json file, both of which are similar to those created by the Sigma cloud editor detailed in the last post.

  • The app folder can be used to manage all the important resources required for your extension. By default, itincludes an index.html file, which serves as the UI for a sample widget.
  • The plugin-manifest.json file helps with extension configuration. It includes a widgets key configured with a default sample widget named, "Projects Extension" in the default location as the task details tab, along with the URL as the location of the index.html file.
Now that the extension project has been created, lets go ahead and test it in the Zoho Projects portal.
Testing an extension project using the CLI
  • To test a sample Zoho Projects extension created with the ZET CLI, use the Change Directory command to navigate to the project folder. Then, run the zet run command.

  • This command starts a local server and enables you to test your extension locally.
  • Now, navigate to your Zoho Projects portal. Click the Setup icon.
  • Select Developer Space from the left panel. Click Enable Developer Mode.

  • Developer Mode will be enabled and the page will automatically refresh.
  • You may now test your extension functionalities in the Zoho Projects portal.
  • Since the sample extension had a default widget called, "Projects Extension" configured on the Task Details page, choose and enter a project task in your portal.

  • Click on the Projects Extension tab on the Task Details page, and you will see that the widget has loaded.

  • Once you have finished testing your extension's functionality, use the zet pack command. This command adds a dist folder to the directory structure, zips the extension project, and places the zipped file inside the newly created dist folder.
Uploading the zipped file to your Sigma extension

Now that we have created the extension project and tested its functionalities locally, lets go ahead and create an extension in Sigma.
  • Once you enter your Sigma workspace, click the New Extension button to build a new extension.
  • Enter a name and description for the extension. Choose Zoho Projects for the service.
  • Toggle Upload Existing File to Yes.

  • Click Browse to locate and upload the extension project's zipped file, accept the terms and conditions, and click Create.

  • You will be redirected to the cloud editor. The directory structure of your CLI extension project will be automatically populated with the project's contents.
Editing an extension created with the CLI
  • You can make edits or changes to your extension code directly from the cloud editor.
  • If you wish to make changes to a file or its contents in the directory structure of your CLI extension project, please be sure to pack the extension project again using the zet pack CLI command.
  • Go to Sigma. Click the Extension Details icon of the extension you wish to edit.

  • Click the Edit icon under the extension name.

  • Browse for and upload the new zipped file, accept the terms and conditions, and click Update.

  • The extension will be updated to reflect the changes you have made.
In this post, we have covered the process of creating an extension for Zoho Projects through ZET CLI. We hope you found this information useful. Keep following this space for more information!
