Implementation Reference
- src/comfyui/client.ts:61-68 (helper)The runWorkflow method on ComfyUIClient that generate_with_workflow's handler calls. Submits the workflow via HTTP POST to /prompt, then polls /history until completion, extracting image URLs.
async runWorkflow(workflow: Workflow): Promise<GenerateResult> { const { prompt_id } = await this.submit(workflow); const entry = await this.waitForCompletion(prompt_id); return { promptId: prompt_id, images: extractImageUrls(entry, this.publicUrl), }; }
