Benefits of dynamic OG image generation
- Easy to use: No headless browser is needed, and you can define images using HTML and CSS Source 0.
- Affordable: Vercel Edge Functions are 160x cheaper than running Chromium in a Serverless Function Source 0.
- Fast: Vercel OG is 100x more lightweight than Chromium + Puppeteer, allowing functions to start almost instantly Source 0.
Next.js OG Image
Another approach is to use Next.js and create an API route that generates OG images with dynamic parameters Source 4. This method involves creating a serverless function that takes dynamic parameters, renders the OG image using a tool like Playwright, and returns it as a response.
Vercel OG
To generate dynamic OG images for blog posts using Vercel OG, you can create a new API route that accepts query parameters and renders the OG image with the given data Source 3. You can embed the dynamically generated OG image on your blog post page using the Head component Source 3.
Satori
Vercel’s new Next.js OG Image functionality, built with the Satori library, can generate dynamic images for all frameworks deployed with Vercel Source 11. This method supports nested images, custom fonts, Google Fonts, and more.
Google Sheets
An alternative approach is to use Google Sheets to generate dynamic Open Graph images without requiring Puppeteer Source 14. This method involves creating a Google Slides template and using the public URL of the image in the meta tags of your website.
Conclusion
In conclusion, there are multiple approaches to generating dynamic OG images, each with its pros and cons. Vercel OG is a popular choice for its speed, affordability, and ease of use. Other methods, such as using Next.js API routes, Satori, or Google Sheets, can also be effective depending on your specific requirements and preferences.
