Vue 3 + SPFX 1.13.1 + Typescript + Vite

Sample Vue 3 app built using Vite that is embedded within an SPFX 1.13.1 webpart

The Microsoft SharePoint Framework (SPFX) v1.31.1 does not have an option for Vue in their Yeoman generator. The PnP/SPFX generator has not been updated to support Vue 3 nor SPFX 1.13.1. This project serves as a brute-force sample of how you could develop in Vue 3 (and optionally Vite as your build environment) and then incorporate it into the latest version of SPFX webparts.

Reasons you might use this project

1. You want to develop SPFX webparts (or application extensions) in Vue 3
2. During development you want to take advantage of TDD and hot reloading that Webpack or Vite provides, which tends to be much faster than the gulp-based SharePoint workbench.
3. You want to use Node v14. Previous versions of SPFX require Node v10 and do not work on later versions, whereas SPFX v1.31.1 works on Node v14.

Recent improvement in this project

1. Automated the embedding process (post-build)
2. Allowed for unique app IDs for each instance of the webpart so that multiple instances of the same webpart can be used on the same SharePoint page simultaneously.
3. Synchronized the package.json version of the main web app with the webpart's package version and webpart version in webpart/config/package-solution.json

Improvements to make in the future

1. Create a script to scaffold a new project based on this structure
2. Consider loading Vue3 from cloud rather than embedding in each webpart

Set up a Vue 3/Vite/SPFX 1.31.1 project

1. Clone this repo to use for your webpart as a template
2. Delete the .git folder and re-initialize this as your own git repo
3. Create your Vue 3 web app in your normal, preferred way, within the top-level of this folder
4. The index.html will allow you to develop and test the webpart web app inside of a simple container to mimick a SharePoint page
5. Delete the contents of the webpart/ folder
6. Generate the SPFX webpart inside of the webpart folder, selecting "No javascript framework":

yo @microsoft/sharepoint

7. If using Vite, modify /vite.config.ts to set the output directory by adding the following build and assetsDir options:

export default defineConfig({
	  plugins: [vue()],
	  build: {
	    outDir: "webpart/src/webparts/assets"
	  },
	  assetsDir: "appcode"
	})

8. Replace your webpart.ts file contents with the one from the webpart-template/src/YOURWebpart/ folder
9. Copy the webpart-template/src/lib/ folder into webpart/src/
10. Replace all occurences of UNIQUECLIENTAPP with an ID name representing your web part
11. Build and ship the webpart using:

./make

12. This should create the webpart sharepoint/solution/...sppkg package that you can upload to the SharePoint site's App Catalog
13. Follow the normal procedure for deploying your webpart to SharePoint
14. When the webpart is initialized, it will:
    • run the render function
    • create an app element
    • call the Vue app scripts to run and populate that element with the Vue app

@PnP/SP

If using @pnp/sp to connect with the SharePoint site:

1. Install it at the web app level (not the web part sub-project):

npm install @pnp/sp

10. Configure 'sp' in src/App.vue with the base path of the SharePoint site containing the web part. See example code in src/App.vue and src/lib/SharePointTools.ts
11. You do not need to initialize 'sp' in the webpart. Just use it directly from the Vue 3 web app.

Editable properties and passing them to the Vue 3 web app

1. Define your editable properties in the webpart/src/webparts/...WebPart.ts file
2. Pass them to the Vue 3 web app in one of several ways:
   • data-attributes on the containing app element that the Vue app can retrieve
   • sessionStorage

Updating the app (and webpart)

Make changes to the Vue3 app in your normal way. Then:

1. Update package.json version
2. Run:

./make

3. An SharePoint webpart package file with the new version number will be created that you can drag into the site's App Catalog

TSConfig

These settings in tsconfig.ts may be helpful:

• "skipLibCheck": true // to ignore type errors in packages such as @pnp/sp
• "exclude": ["**/*.stories.ts"] // to ignore react JSX types that don't apply to a Vue app:
