海外TECH	DEV Community	Open Graph images	https://dev.to/krasun/open-graph-images-38lg	Open Graph imagesAlso known as social cards or link previews these images make a difference between the click and the visit to your site or ignoring it Boost your brand awareness by generating Open Graph images In this article I share with you a few quick ways how you can easily add support the Open Graph images to your site If you already have an imageIf you already have an image for social media upload it to your server or any other file hosting and add the following tags to your HTML head section lt Open Graph Meta Facebook gt lt meta property og type content website gt lt meta property og url content gt lt meta property og title content Your title gt lt meta property og description content Your description gt lt meta property og image content gt lt Twitter gt lt meta property twitter card content summary large image gt lt meta property twitter url content gt lt meta property twitter title content Your title gt lt meta property twitter description content Your description gt lt meta property twitter image content gt There are a few requirements and recommendations to avoid common pitfalls Don t use a relative URL Always use an absolute URL of the images in tags Not every social network or app knows how to resolve it The recommended image size is xpx for most social networks and the file size must not exceed a few hundred kilobytes And there are a few downsides to using static OG images They are not updated dynamically to reflect the updates on a page You need manually set up OG images for different pages You need to spend time and periodically update them These downsides can be solved by generating images dynamically Generate open graph images dynamicallyThere are two ways to generate Open Graph images dynamically building a custom solution with a rendering engine like Puppeteer or using a well established API or product that solves that problem What to choose depends on your preferences and resource limitations If you like building and writing code go with a custom solution If you are short on time go with a proven solution Generate Open Graph images with a custom solutionYou can draw pictures using low level libraries or render HTML with browsers and take screenshots There are so many ways to generate images dynamically I will show quickly two options on how to easily render HTML as an image for open graph images Using Puppeteer And using satori by Vercel Why HTML as images Because it is a declarative language that is easy to read and edit In addition to that you can use modern CSS frameworks to style your OG image quickly And you can easily scale elements to larger or lesser image sizes if needed Using Puppeteer to generate OG imagesI have written a complete guide on how to render URLs or HTML as images screenshots with Puppeteer Before rendering an HTML let s create a simple example of a dynamic HTML template for our OG image lt doctype html gt lt html gt lt head gt lt meta charset UTF gt lt meta name viewport content width device width initial scale gt lt script src gt lt script gt lt head gt lt body class bg violet h screen

Are easy and powerful way to increase your brand awarness lt h gt lt div gt lt body gt lt html gt And now let s render it with Puppeteer use strict npm i puppeteerimport puppeteer from puppeteer async

res send image catch e console error e res status send Failed to render the Open Graph image see error logs finally await browser close app listen I start and close a browser on every request because these requests from social networks might be rare if the number of pages you have is minimal But running a browser in the background might cause many issuesーit is a complex case to handle Let s test it http localhost ogi prefix Open Graph amp title images amp subtitle are easy and powerful way to increase your awarenessAnd the result is Once it works specify URLs in your HTML meta tags lt Open

content title images amp subtitle are easy and powerful way to increase your awareness gt Use your domain where you deployed the API instead of example com And the last is you need to deploy an API or integrate it as part of your app But be careful because deploying Puppeteer manually to a server has a few pitfalls that you should be aware of It might have memory leaks It consumes a lot of CPU and memory It might periodically crash There is a new and lightweight alternative tailored for rendering OG imagesーsatori by Vercel Or if you don t want to deal with infrastructure and code feel free to jump to the section about how to use API to render HTML Using satori by Vercel to generate OG imagessatori is an engine made by Vercel to generate SVG images from simple HTML code that can be used in many use cases And Vercel provides native support for satori to render Open Graph images If you need to generate OG images for your Next js app consider hosting your app on Vercel and using their OG image solution Install satori and friends npm i satori satori html resvg resvg jsLet s render a simple HTML use strict import satori from satori import Resvg from resvg resvg js import html as

where you deployed the API instead of example com The beauty of using satori instead of Puppeteer is that it works faster consumes less memory and can be embedded into your main app But the downside is that satori is a comparatively new library so it might have a lot of rendering issues and it doesn t fully support all the latest HTML and CSS properties If your rendering capabilities for you are enough to use satori I would advise going with it But if you want to make sure that everything works like a charm and supports the latest HTML features I would advice using an established API to render images Using simple and tailored solution for Open Graph imagesIn case you want to save time and money and don t want to deal with HTML rendering engines and headless browsers You can use a well established screenshot API to generate OG imagesーScreenshotOne Let s examine how easier it is use an API rather Puppeteer or rendering engine like satori First sign up at ScreenshotOne to get an API key Then install an official SDK for JavaScript but it is available for many languages npm i screenshotone api sdkLet s render an image import as screenshotone from screenshotone api sdk create

solution test it and it works fine Test and validate your open graph images with official debuggers Use a debugger from Meta Facebook Try a social card validator from Twitter Test with a LinkedIn Post Inspector Use a Pinterest URL debugger For Telegram WhatsApp or iMessage send the link to your friend Known issuesI encountered many issues while rendering and working with OG images And I want to share them with you Open Graph image requirementsThe recommended image size is xpx for most social networks and the file size must not exceed a few hundred kilobytes Refresh cache for OG image in TelegramIn order to refresh the cache if the image has been changed go to webpagebot and send the URL is maximum you want to clear the cache for Telegram servers automatically will scan your site and generate a new Open Graph image preview site name and description Remember to have the OG prefix in your HTML tag as lt html prefix og gt or the Telegram bot will not update the graph cache Always use an absolute URLIt might be a simple task for you but many apps don t crawl an OG image path right if it is specified as relative Always specify an absolute URL including the host and protocol to the image lt Not this gt lt meta property og image content image png gt lt meta property twitter image content image png gt lt But this gt lt meta property og image content gt lt meta property twitter image content gt A few tips on the social card designI prepared a few tips that you might find helpful to increase the click rate for the link to your site on social media networks They are not proven to be always working it is not a science and you need to test it Place a button on the imageMany reported that placing a button on the OG image increased click through rate Nothing is guaranteed You may want to test it Increase the font sizeUnless it is an intention or design effect to attract attention don t use small fonts and make the font size as large as possible Test if you can read the text on the resulting image Brand colors and fontsObvious but many forget to reuse their brand colors and fonts Social cards aim to increase your brand awareness and if possible to invite users for a click Adapt to social networks if possibleAlways test how it looks in social networks white and back styles And you might try to adapt to Twitter because twitter has a special meta tag You can try to play with Twitter colors and button styles to make it feels native A closing thoughtIn case you like building I advise you to use Puppeteer or satori from Vercel especially if you use Next js But if you want a quick and hassle free solution feel free to use ScreenshotOne API which is ready to render any kind of HTML for your needs I hope you enjoyed our journey to link previews and how to generate them Have a nice day	2022-12-04 12:07:47
