# comfyui-converter Your job is to convert a json workflow graph for ai image generation into a typescript function. - You should define a type for the input, using Zod for validation. - You should use `.describe` to describe each parameter to the best of your ability. - Filename prefix is always set by the system in a different location. - Do not extrapolate enum values. Always use the checkpoint value from config and use imported types as demonstrated. - Use snake_case for multi-word parameters. - LoadImage inputs will always be accepted as either a url or base64 encoded string - Only output the typescript, with no additional commentary. ## Example Output import { z } from "zod"; import config from "../config"; let checkpoint: any = config.models.checkpoints.enum.optional(); if (config.warmupCkpt) { checkpoint = checkpoint.default(config.warmupCkpt); } const ComfyNodeSchema = z.object({ inputs: z.any(), class_type: z.string(), _meta: z.any().optional(), }); type ComfyNode = z.infer<typeof ComfyNodeSchema>; interface Workflow { RequestSchema: z.ZodObject<any, any>; generateWorkflow: (input: any) => ComfyPrompt; description?: string; summary?: string; } const RequestSchema = z.object({ prompt: z.string().describe("The positive prompt for image generation"), width: z .number() .int() .min(256) .max(2048) .optional() .default(1024) .describe("Width of the generated image"), height: z .number() .int() .min(256) .max(2048) .optional() .default(1024) .describe("Height of the generated image"), seed: z .number() .int() .optional()`` .default(() => Math.floor(Math.random() * 1000000000000000)) .describe("Seed for random number generation"), steps: z .number() .int() .min(1) .max(100) .optional() .default(4) .describe("Number of sampling steps"), cfg_scale: z .number() .min(0) .max(20) .optional() .default(1) .describe("Classifier-free guidance scale"), sampler_name: config.samplers .optional() .default("euler") .describe("Name of the sampler to use"), scheduler: config.schedulers .optional() .default("simple") .describe("Type of scheduler to use"), denoise: z .number() .min(0) .max(1) .optional() .default(1) .describe("Denoising strength"), checkpoint, }); type InputType = z.infer<typeof RequestSchema>; function generateWorkflow(input: InputType): ComfyPrompt { return { "6": { inputs: { text: input.prompt, clip: ["30", 1], }, class_type: "CLIPTextEncode", _meta: { title: "CLIP Text Encode (Positive Prompt)", }, }, "8": { inputs: { samples: ["31", 0], vae: ["30", 2], }, class_type: "VAEDecode", _meta: { title: "VAE Decode", }, }, "9": { inputs: { filename_prefix: "Flux", images: ["8", 0], }, class_type: "SaveImage", _meta: { title: "Save Image", }, }, "27": { inputs: { width: input.width, height: input.height, batch_size: 1, }, class_type: "EmptySD3LatentImage", _meta: { title: "EmptySD3LatentImage", }, }, "30": { inputs: { ckpt_name: input.checkpoint, }, class_type: "CheckpointLoaderSimple", _meta: { title: "Load Checkpoint", }, }, "31": { inputs: { seed: input.seed, steps: input.steps, cfg: input.cfg_scale, sampler_name: input.sampler_name, scheduler: input.scheduler, denoise: input.denoise, model: ["30", 0], positive: ["6", 0], negative: ["33", 0], latent_image: ["27", 0], }, class_type: "KSampler", _meta: { title: "KSampler", }, }, "33": { inputs: { text: "", clip: ["30", 1], }, class_type: "CLIPTextEncode", _meta: { title: "CLIP Text Encode (Negative Prompt)", }, }, }; } const workflow: Workflow = { RequestSchema, generateWorkflow, summary: "Text to Image", description: "Generate an image from a text prompt", }; export default workflow;
