海外TECH	DEV Community	CDN Caching, Static Site Generation and Server Side Rendering	https://dev.to/jmalvarez/cdn-caching-static-site-generation-and-server-side-rendering-4hom	CDN Caching Static Site Generation and Server Side RenderingHere we are analyzing the different types of pre rendering a website and its combination with a CDN Static Site GenerationEvery single page of a website is first built and then uploaded to a CDN The best part of this is that as the website is static the user does not have to interact with the server The CDN can directly return the static generated site so the user gets a fast response The disadvantage is that every time you want to update the website you have to build the whole website again and upload it to the CDN This costs money Server Side Rendering without CDNPages are built on demand with Server Side Rendering When a user requests a page the user has to wait until the page is built and returned from the server Because of this response time is slow Every visit to a page generates a build In comparison to Static Site Generation where every page is always built here only the pages that are visited are built If no one visits a page it is never built The disadvantage is that for every request we have to build the page Server Side Rendering with CDNIn this case the first visitor of a page requests the page to the CDN and the CDN requests it to the server which builds it and returns it back But for the second visitor the CDN will already have the page at cache and can directly return it without generating a new build The problem here is that every next visitor is going to receive the build that was generated for the first visitor What happens if the page is stale With max age we can control how long the page can be cached When the page is stale the CDN will request a new build on the next request after max age Depending on the kind of the page we could set a different max age We can combine max age with s maxage The CDN will cache a page using s maxage instead of max age if it is present User s browser will ignore s maxage This can be very useful if we purge the website pages in the CDN when they are rebuilt As we don t have control over the user s browser we should have a max age that is lower than the s maxage otherwise we could have an updated version of a page in the CDN which the user would never request because the user s browser had an older version which would be still valid according to max age For example we could set a max age of one minute or one day and a s maxage of one year This way the user would request the page to the CDN frequently and the CDN would never request a new build because according to s maxage the page would still be valid We would update the cache on the CDN by purging the previous page and uploading the new one Incremental Static Site RegenerationInitially the whole website is built and uploaded to the CDN as with Static Site Generation But here if a user requests a page the CDN will return the current cached page and it will also request to the server a new build of only that page This way the next user will get the new build and the CDN will again request a new one to the server Every user gets a fast response and only the pages that are requested are updated This is a technique used by Next js I recommend reading their documentation to get a better understanding of this Server Side Rendering with Stale While Revalidatestale while revalidate can be added to the cache control header What does it do If a request comes after max age the CDN returns a stale version of the page while the server is building a fresh one stale while revalidate specifies in seconds for how long can the stale version be returned The first time a user requests a page it will be generated in the server and uploaded to the CDN If a new request comes before max age then the CDN will just return it If a request comes after max age then the CDN will return the stale version but this time it will request the server a new fresh copy Every user that requests the page while it is being built will get the stale version If after max age a request comes and stale while revalidate has also passed then the CDN won t return a stale version and it will wait until a new version is generated in the server From the user s perspective it is exactly the same as Incremental Static Site Regeneration Only that here we don t have to build the whole website for the first deployment the first visitor will trigger the build of the page that he s visiting ResourcesNext js documentationWeb dev stale while revalidateMDN cache controlYoutube com CDN Caching Static Site Generation and Server Side Rendering	2022-09-03 22:37:09
