海外TECH	DEV Community	Automatically Serve WebP Images with Silverstripe and NGINX	https://dev.to/theloveduckie/automatically-serve-webp-images-with-silverstripe-and-nginx-beg	Automatically Serve WebP Images with Silverstripe and NGINX OverviewFast page load times are vital for any modern website with heavy traffic To achieve quick response times it often this means having to compress minify and cache static page assets that are served regularly on page load including JavaScript plain HTML or images in particular However the problem with heavy compression often comes with a loss of quality in image assets which can compromise aesthetics or styling and detract from overall user experience WebPFortunately there s a solution to serving mostly lossless images with small payloads Quoting from WebP s homepage WebP is a modern image format that provides superior lossless and lossy compression for images on the web Using WebP webmasters and web developers can create smaller richer images that make the web faster The WebP image file format is not anything terribly new and has been for a while now however many websites have yet to implement steps for generating webp images from their existing image assets Integrating with SilverstripeAs a case study for this blog I ve decided to talk about how to integrate the usage of this image file format with Silverstripe What is Silverstripe For those of you who don t already know Silverstripe CMS is a free and open source content management system and framework for creating and maintaining websites and web applications It provides an out of the box web based administration panel that enables users to make modifications to parts of the website which includes a WYSIWYG website editor You can otherwise consider it as an alternative CMS to WordPress although arguably better and less bloated Assuming that you already are working on a Silverstripe project you can install a convenient module that I ve developed that will automatically convert any image asset that has been rasterized resized or scaled from your Silverstripe project through using Silverstripe s image templating syntax You can install the module with the following command composer require loveduckie silverstripe webp imageAfter installing this with the Composer package manager simply run dev build flush all Without having done anything else your Silverstripe project is now automatically generating and serving webp assets on page load Woah Let s take a look at how it s achieving this If we take a look at the repository for the module you will see that we are using a LibGD function made available as part of PHP for converting PNG images when intercepting requests for serving assets This line in particular public function createWebPImage path filename hash variant false if function exists imagewebp amp amp function exists imagecreatefromjpeg amp amp function exists imagecreatefrompng amp amp function exists imagecreatefromgif orgpath this gt getAsURL filename hash variant list width height type attr getimagesize path switch type case img imagecreatefromjpeg path imagewebp img this gt createWebPName orgpath this gt webp quality break case img imagecreatefrompng path imagesavealpha img true save alphablending setting important imagewebp img this gt createWebPName orgpath this gt webp quality break imagedestroy img After the conversion is made in memory using imagewebp it then gets served to disk using the file path generated by createWebPName orgPath This path is something along the lines of this silverstripe project root public assets Upload your image filename png webpThe way that the file is named is important to note for later on Serving Generated WebP Images from NGINXYou can use the following NGINX configuration for serving WebP images automatically from your Silverstripe project s public assets directory You can compare this configuration to the default one that Silverstripe has on their documentation pages for NGINX connectivity with PHP FPM map http accept webp suffix default webp webp server listen listen server name WEBSITE DOMAIN NAMES server tokens off include etc nginx mime types location try files uri index php query string location assets lt extension gt jpe g png gif webp gzip static on gzip types image png image x icon image webp image svg xml image jpeg image gif add header Vary Accept expires max sendfile on try files request uri webp suffix uri location index php fastcgi read timeout fastcgi buffers k fastcgi buffer size k fastcgi busy buffers size k fastcgi keep conn on fastcgi pass your php fpm server goes here fastcgi index index php fastcgi param SCRIPT FILENAME document root fastcgi script name include etc nginx fastcgi params From the snippet above WEBSITE DOMAIN NAMES is automatically replaced when the NGINX server starts by using envsubst but you can replace it with your own domain names too I ve simply taken this configuration from my own webserver as I am using the Alpine Linux Docker container image for NGINX The most important part of this configuration is this section map http accept webp suffix default webp webp You can think of it as a switch statement in most languages Depending on what http accept resolves to when a request is served will ultimately determine whether the resulting variable webp suffix will resolve to either webp or nothing This resulting variable will then be used when serving static files from the assets directory which occurs in this part of the configuration location assets lt extension gt jpe g png gif webp gzip static on gzip types image png image x icon image webp image svg xml image jpeg image gif add header Vary Accept expires max sendfile on try files request uri webp suffix uri This configuration block basically instructs NGINX to respond to requests that end with the suffix of jpeg png gif or webp It will then attempt to locate and serve the webp of the same requesting asset if the Accept header has been defined to include webp You can see that happening on this line try files request uri webp suffix uri Depending on what the incoming browser request has in their Accept header will automatically determine if the webp suffix is populated which will in turn decide which version of the same asset is retrieved from your server s filesystem Once you ve applied this configuration you can then run the following command to test it nginx tFollowed by this one to reload it assuming that the previous one did not fail nginx s reloadNow when you navigate to your running Silverstripe project you should notice something interesting if you open up your Developer Console in Chrome You ll notice that even though your browser is loading an image asset with a jpeg extension the MIME type for the response is that of image webp This means that NGINX was able to locate the generated webp image asset and was able to serve it back This is good news ConclusionAnd there you have it An end to end solution for integrating webp image assets with your Silverstripe project and how to serve them through a modern web server such as NGINX Using some clever NGINX configuration trickery we can automatically pick and serve webp should it be discoverable on the filesystem These image assets are being automatically generated by Silverstripe whenever templates are being rendered that make use of the syntax for manipulating images Useful LinksNGINX configuration for Silverstripe with WebP image servingThanks for reading Feel free to follow me on Twitter or check out my website where I
