Ideogram Data Handling

Ideogram Data Handling

Overview

Manage generated image assets from Ideogram. Covers prompt metadata tracking, image asset lifecycle management, download and local storage patterns, and generation history for brand consistency auditing.

Prerequisites

• Ideogram API key
• Image storage (local filesystem, S3, or GCS)
• Understanding of image formats and metadata
• Asset management process defined

Instructions

Step 1: Track Generation Metadata

interface GenerationRecord {
  id: string;
  prompt: string;
  negativePrompt?: string;
  model: string;
  aspectRatio: string;
  seed?: number;
  imageUrl: string;
  localPath?: string;
  generatedAt: string;
  expiresAt: string; // Ideogram URLs are temporary
}

const generationHistory: GenerationRecord[] = [];

async function generateWithTracking(prompt: string, options: any = {}) {
  const response = await fetch('https://api.ideogram.ai/generate', {
    method: 'POST',
    headers: {
      'Api-Key': process.env.IDEOGRAM_API_KEY!,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      image_request: {
        prompt,
        model: options.model || 'V_2',
        aspect_ratio: options.aspectRatio || 'ASPECT_1_1',
        magic_prompt_option: 'AUTO',
      },
    }),
  });

  const result = await response.json();
  const image = result.data?.[0];

  if (image) {
    const record: GenerationRecord = {
      id: `gen_${Date.now()}`,
      prompt,
      model: options.model || 'V_2',
      aspectRatio: options.aspectRatio || 'ASPECT_1_1',
      seed: image.seed,
      imageUrl: image.url,
      generatedAt: new Date().toISOString(),
      expiresAt: new Date(Date.now() + 3600000).toISOString(), // ~1hr  # 3600000 = configured value
    };
    generationHistory.push(record);
    return record;
  }

  throw new Error('No image generated');
}

Step 2: Download and Persist Images

import { writeFileSync, mkdirSync, existsSync } from 'fs';
import { join } from 'path';

async function downloadImage(record: GenerationRecord, outputDir: string) {
  mkdirSync(outputDir, { recursive: true });

  const response = await fetch(record.imageUrl);
  if (!response.ok) throw new Error(`Download failed: ${response.status}`);

  const buffer = Buffer.from(await response.arrayBuffer());
  const filename = `${record.id}.png`;
  const filePath = join(outputDir, filename);

  writeFileSync(filePath, buffer);
  record.localPath = filePath;

  return filePath;
}

// Download immediately since URLs expire
async function generateAndPersist(
  prompt: string,
  outputDir = './generated-images'
) {
  const record = await generateWithTracking(prompt);
  await downloadImage(record, outputDir);
  return record;
}

Step 3: Asset Lifecycle Management

import { unlinkSync, existsSync } from 'fs';

function cleanExpiredAssets(
  records: GenerationRecord[],
  retentionDays = 30
) {
  const cutoff = Date.now() - retentionDays * 86400000;  # 86400000 = configured value
  const results = { kept: 0, deleted: 0 };

  for (const record of records) {
    if (new Date(record.generatedAt).getTime() < cutoff) {
      if (record.localPath && existsSync(record.localPath)) {
        unlinkSync(record.localPath);
      }
      results.deleted++;
    } else {
      results.kept++;
    }
  }

  return results;
}

Step 4: Generation History Export

function exportGenerationHistory(records: GenerationRecord[]) {
  return records.map(r => ({
    id: r.id,
    prompt: r.prompt,
    model: r.model,
    seed: r.seed,
    generatedAt: r.generatedAt,
    hasLocalCopy: !!r.localPath && existsSync(r.localPath),
  }));
}

function findByPrompt(records: GenerationRecord[], searchTerm: string) {
  return records.filter(r =>
    r.prompt.toLowerCase().includes(searchTerm.toLowerCase())
  );
}

Error Handling

Examples

Batch Generate and Store

async function batchGenerateAssets(prompts: string[]) {
  const results = [];
  for (const prompt of prompts) {
    const record = await generateAndPersist(prompt);
    results.push(record);
    await new Promise(r => setTimeout(r, 3000)); // Rate limit  # 3000: 3 seconds in ms
  }
  return results;
}
