Ideogram CI Integration

Overview

Set up CI/CD pipelines for Ideogram integrations. Since Ideogram has no free tier for API testing, CI strategies focus on: mocked unit tests (free), optional integration tests gated behind secrets, and prompt validation without API calls.

Prerequisites

• GitHub repository with Actions enabled
• Ideogram API key for integration tests (optional)
• npm/pnpm project with vitest

Instructions

Step 1: GitHub Actions Workflow

# .github/workflows/ideogram-ci.yml
name: Ideogram Integration CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  unit-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"
      - run: npm ci
      - run: npm test -- --reporter=verbose
      - run: npm run lint

  # Optional: runs only when secret is configured
  integration-tests:
    runs-on: ubuntu-latest
    if: github.event_name == 'push' && github.ref == 'refs/heads/main'
    env:
      IDEOGRAM_API_KEY: ${{ secrets.IDEOGRAM_API_KEY }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"
      - run: npm ci
      - name: Run integration tests
        if: env.IDEOGRAM_API_KEY != ''
        run: npm run test:integration
        timeout-minutes: 5

Step 2: Configure Secrets

set -euo pipefail
# Store Ideogram API key in GitHub repository secrets
gh secret set IDEOGRAM_API_KEY

# Verify it was set
gh secret list

Step 3: Unit Tests with Mocked API

// tests/ideogram-generate.test.ts
import { describe, it, expect, vi, beforeEach, afterEach } from "vitest";

const mockGenerateResponse = {
  created: "2025-01-15T10:00:00Z",
  data: [{
    url: "https://ideogram.ai/assets/image/mock-123.png",
    prompt: "test prompt",
    resolution: "1024x1024",
    is_image_safe: true,
    seed: 42,
    style_type: "DESIGN",
  }],
};

describe("Ideogram Generate", () => {
  let fetchSpy: any;

  beforeEach(() => {
    fetchSpy = vi.spyOn(globalThis, "fetch").mockResolvedValue(
      new Response(JSON.stringify(mockGenerateResponse), {
        status: 200,
        headers: { "Content-Type": "application/json" },
      })
    );
  });

  afterEach(() => fetchSpy.mockRestore());

  it("sends correct headers", async () => {
    await fetch("https://api.ideogram.ai/generate", {
      method: "POST",
      headers: { "Api-Key": "test-key", "Content-Type": "application/json" },
      body: JSON.stringify({ image_request: { prompt: "test" } }),
    });

    expect(fetchSpy).toHaveBeenCalledWith(
      "https://api.ideogram.ai/generate",
      expect.objectContaining({
        headers: expect.objectContaining({ "Api-Key": "test-key" }),
      })
    );
  });

  it("parses response correctly", async () => {
    const response = await fetch("https://api.ideogram.ai/generate", {
      method: "POST",
      headers: { "Api-Key": "test-key", "Content-Type": "application/json" },
      body: JSON.stringify({ image_request: { prompt: "test" } }),
    });
    const result = await response.json();
    expect(result.data[0].seed).toBe(42);
    expect(result.data[0].is_image_safe).toBe(true);
  });

  it("handles 429 rate limit", async () => {
    fetchSpy.mockResolvedValueOnce(new Response("Rate limited", { status: 429 }));
    const response = await fetch("https://api.ideogram.ai/generate", {
      method: "POST",
      headers: { "Api-Key": "test-key", "Content-Type": "application/json" },
      body: JSON.stringify({ image_request: { prompt: "test" } }),
    });
    expect(response.status).toBe(429);
  });
});

Step 4: Prompt Validation in CI (No API Key Required)

// tests/prompt-validation.test.ts
import { describe, it, expect } from "vitest";

const VALID_STYLES = ["AUTO", "GENERAL", "REALISTIC", "DESIGN", "RENDER_3D", "ANIME"];
const VALID_ASPECTS = [
  "ASPECT_1_1", "ASPECT_16_9", "ASPECT_9_16", "ASPECT_3_2", "ASPECT_2_3",
  "ASPECT_4_3", "ASPECT_3_4", "ASPECT_10_16", "ASPECT_16_10", "ASPECT_1_3", "ASPECT_3_1",
];

function validateIdeogramRequest(req: any): string[] {
  const errors: string[] = [];
  if (!req.prompt || req.prompt.length === 0) errors.push("Prompt is required");
  if (req.prompt?.length > 10000) errors.push("Prompt exceeds 10,000 char limit");
  if (req.style_type && !VALID_STYLES.includes(req.style_type)) {
    errors.push(`Invalid style_type: ${req.style_type}`);
  }
  if (req.aspect_ratio && !VALID_ASPECTS.includes(req.aspect_ratio)) {
    errors.push(`Invalid aspect_ratio: ${req.aspect_ratio}`);
  }
  if (req.num_images && (req.num_images < 1 || req.num_images > 4)) {
    errors.push("num_images must be 1-4");
  }
  return errors;
}

describe("Prompt Validation", () => {
  it("accepts valid request", () => {
    const errors = validateIdeogramRequest({
      prompt: "A sunset over mountains",
      style_type: "REALISTIC",
      aspect_ratio: "ASPECT_16_9",
    });
    expect(errors).toHaveLength(0);
  });

  it("rejects empty prompt", () => {
    const errors = validateIdeogramRequest({ prompt: "" });
    expect(errors).toContain("Prompt is required");
  });

  it("rejects invalid style", () => {
    const errors = validateIdeogramRequest({ prompt: "test", style_type: "INVALID" });
    expect(errors[0]).toContain("Invalid style_type");
  });
});

Step 5: Integration Test (API Key Required)

// tests/integration/ideogram-live.test.ts
import { describe, it, expect } from "vitest";

describe.skipIf(!process.env.IDEOGRAM_API_KEY)("Ideogram Live API", () => {
  it("generates an image successfully", async () => {
    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: "CI test: simple geometric shape",
          model: "V_2_TURBO",
          magic_prompt_option: "OFF",
        },
      }),
    });

    expect(response.status).toBe(200);
    const result = await response.json();
    expect(result.data).toHaveLength(1);
    expect(result.data[0].url).toContain("http");
    expect(result.data[0].is_image_safe).toBe(true);
  }, 30000); // 30s timeout for generation
});
