Getting Began with the Apps Script Starter

The Starter equipment is a boilerplate for rapidly getting began with native Apps Script growth regionally inside VS Code. Open your terminal and run the next instructions:

Subsequent, bounce to the command line terminal and run the deploy command to push your code to the Apps Script challenge.

npm run deploy

After the deployment is full, open the related script within the browser with the CLASP open command.

npx clasp open

Contained in the Apps Script Editor, go to the Run menu and select the getEmailAddress operate from the listing. Open the logs and you must see your e mail addresses within the window.

Then go to the Publish menu, select Deploy as internet app and open the URL in a brand new browser tab to examine this system output. That’s how straightforward it’s to construct initiatives with the Google Apps Script starter equipment.
