Yeoman generator for Office Add-ins - YO OFFICE!

npm version
Downloads

This Yeoman generator creates a Node.js Office Add-in project that can be managed with Visual Studio Code or any other editor. You can use it to create Office Add-ins for:

  • Excel
  • OneNote
  • Outlook
  • PowerPoint
  • Project
  • Word

In addition you can use it to create add-ins that use single sign-on or Excel custom functions.

Like other Yeoman generators, this generator simply creates the scaffolding of files for your Office Add-in project. You can choose to create Office Add-in projects using plain HTML, CSS & JavaScript, or using React, and can choose between JavaScript and Typescript as well.

Note: While you can also use Visual Studio to create Office Add-in projects, the Yeoman generator provides more options in terms of the types of projects you can create. For example:

  • The Yeoman generator can create Office Add-in projects that use plain HTML, CSS & JavaScript, or React; whereas Visual Studio can only create Office Add-in projects that use plain HTML, CSS & JavaScript.
  • The Yeoman generator can create Office Add-ins projects that use either JavaScript or TypeScript; whereas Visual Studio only creates JavaScript projects which you would need to convert manually if you want to use TypeScript.
  • The Yeoman generator can create add-ins for Excel, OneNote, Outlook, PowerPoint, Project, and Word; whereas Visual Studio can only create add-ins for Excel, Outlook, PowerPoint, and Word.

For detailed information about installing and using the Yeoman generator to create Office Add-ins, see Create Office Add-in projects using the Yeoman Generator.

The generator is normally used in interactive mode, but you can use command line arguments and options as described in the sections below.

Command Line Options

The following command line options are supported. If these are not specified, the generator will prompt you for the values before scaffolding the project. The options should be specified after the projectType, name and host arguments.

Specifying --output tells the generator to create the project in a specific location. If the output parameter is not specified, the project will be created in the current directory. If the output option specifies a non-empty folder,
the generator will inform you so you don't accidentally overwrite existing files.

  • Type: String

  • Optional

--skip-install

After scaffolding the project, the generator (and all sub generators) run all package management install commands such as npm install & typings install. Specifying --skip-install tells the generator to skip this step.

  • Type: Boolean
  • Default: False
  • Optional

Running the Generated Site

Launch the local HTTPS site on https://localhost:3000 by simply typing the following command in your console:

bash
npm start

Note: Office Add-ins should use HTTPS, not HTTP, even when you are developing. If you are prompted to install a certificate after you run npm start, accept the prompt to install the certificate that the Yeoman generator provides.

Next, sideload the add-in in an Office application. See Sideload an Office Add-in for testing.

Validate manifest.xml

As you modify your manifest.xml file, use the included Office Toolbox to ensure that your XML file is correct and complete. It will also give you information on against what platforms to test your add-ins before submitting to the store.

To run Office Add-in Validator, use the following command in your project directory:

bash
npm run validate

For more information on manifest validation, refer to our add-in manifests documentation.
