sampleblock

Sampleblock is a reference implementation of a Salesforce Marketing Cloud Content Builder custom block, built using the official blocksdk. It provides a working Node.js app structure with webpack configuration, a local development server, and a deployable Heroku setup. Developers can clone the repository, swap in their own logic in src/main.js and dist/index.html, and test locally using the SFMC block tester tool at localhost:3000. The project is intended as a starting point rather than a fork, enabling teams to quickly scaffold new custom content blocks for SFMC Content Builder without building from scratch.

Clone the repository (do not fork), set a new git remote pointing to your own repository, then run `npm install` and `npm start` to launch the local server. Edit src/main.js for block logic and dist/index.html for markup, then run `npm run build; npm start` to test changes. Navigate to the block tester app and enter `http://localhost:3000` to preview your block. One-click Heroku deployment is also available via the included app.json.
