## Prerequisites
|
|
|
|
- An existing project
|
|
- A [Trigger.dev account](https://cloud.trigger.dev) with Trigger.dev [initialized in your project](/quick-start)
|
|
- A [Fal.ai](https://fal.ai/) account
|
|
|
|
## Task code
|
|
|
|
This task generates an image from a prompt using Fal.ai.
|
|
|
|
```ts trigger/fal-ai-image-from-prompt-realtime.ts
|
|
import * as fal from "@fal-ai/serverless-client";
|
|
import { logger, schemaTask } from "@trigger.dev/sdk";
|
|
import { z } from "zod";
|
|
|
|
export const FalResult = z.object({
|
|
images: z.tuple([z.object({ url: z.string() })]),
|
|
});
|
|
|
|
export const payloadSchema = z.object({
|
|
imageUrl: z.string().url(),
|
|
prompt: z.string(),
|
|
});
|
|
|
|
export const realtimeImageGeneration = schemaTask({
|
|
id: "realtime-image-generation",
|
|
schema: payloadSchema,
|
|
run: async (payload) => {
|
|
const result = await fal.subscribe("fal-ai/flux/dev/image-to-image", {
|
|
input: {
|
|
image_url: payload.imageUrl,
|
|
prompt: payload.prompt,
|
|
},
|
|
onQueueUpdate: (update) => {
|
|
logger.info("Fal.ai processing update", { update });
|
|
},
|
|
});
|
|
|
|
const $result = FalResult.parse(result);
|
|
const [{ url: cartoonUrl }] = $result.images;
|
|
|
|
return {
|
|
imageUrl: cartoonUrl,
|
|
};
|
|
},
|
|
});
|
|
```
|
|
|
|
### Testing your task
|
|
|
|
You can test your task by triggering it from the Trigger.dev dashboard. Here's an example payload:
|
|
|
|
```json
|
|
{
|
|
"imageUrl": "https://static.vecteezy.com/system/resources/previews/005/857/332/non_2x/funny-portrait-of-cute-corgi-dog-outdoors-free-photo.jpg",
|
|
"prompt": "Dress this dog for Christmas"
