description: "This example project creates memes using OpenAI's DALL-E 3 with a human-in-the-loop approval workflow built using Trigger.dev waitpoint tokens."

|
## Overview
|
|
|
|
This demo is a full stack example that uses the following:
|
|
|
|
- A [Next.js](https://nextjs.org/) app, with an [endpoint](https://github.com/triggerdotdev/examples/blob/main/meme-generator-human-in-the-loop/src/app/endpoints/[slug]/page.tsx) for approving the generated memes
|
|
- [Trigger.dev](https://trigger.dev) tasks to generate the images and orchestrate the waitpoint workflow
|
|
- [OpenAI DALL-E 3](https://platform.openai.com/docs/guides/images) for generating the images
|
|
- A [Slack app](https://api.slack.com/quickstart) for the human-in-the-loop step, with the approval buttons linked to the endpoint

## Relevant code
|
|
|
|
- **Meme generator task**:
|
|
|
|
- The [memegenerator.ts](https://github.com/triggerdotdev/examples/blob/main/meme-generator-human-in-the-loop/src/trigger/memegenerator.ts) task:
|
|
- Generates two meme variants using DALL-E 3
|
|
- Uses [batchTriggerAndWait](/triggering#yourtask-batchtriggerandwait) to generate multiple meme variants simultaneously (this is because you can only generate 1 image at a time with DALL-E 3)
|
|
- Creates a [waitpoint token](/wait-for-token)
|
|
- Sends the generated images with approval buttons to Slack for review
|
|
- Handles the approval workflow
|
|
|
|
- **Approval Endpoint**:
|
|
- The waitpoint approval handling is in [page.tsx](https://github.com/triggerdotdev/examples/blob/main/meme-generator-human-in-the-loop/src/app/endpoints/[slug]/page.tsx), which processes:
|
|
- User selections from Slack buttons
|
|
- Waitpoint completion with the chosen meme variant
|
|
- Success/failure feedback to the approver
|
