Instead, I decided to call the function in the getStaticProps function of my index.js page. However, their method modifies the file to run the function as a script. I found a way ( advocated by Next.js) to generate a sitemap.xml file in the /public folder at build time. The best of both worldsįor my sitemap, I didn’t like the idea of having to manually update it every time, nor did I like the added overhead with Dynamic Generating. This also affects loading times, as the sitemap won’t be served until all the content is fetched and built. However, if you’re fetching data from a CMS, such as custom posts, this means that for every request to your Next.js site, there will also be one to the CMS which greatly increases overhead. This is done by specifying a revalidate time: I’ll call this Dynamic Generation.Īs for Incremental Static Regeneration (ISR), it’s a balance between build-time and dynamic content: The content is generated at build time, but is regenerated in the background on every request (meaning that the visitor doesn’t get disrupted), in a specified window. It’s commonly called Server Side Rendering (SSR), which isn’t very appropriate as it implies that other forms of generating content don’t involve any action from the server. On a Next.js page, this is characterized by exporting a getServerSideProps function. For example, this is what a PHP-based site does for every page written in PHP. Dynamic content: This content is created every time someone visits a page.It would be more appropriate to call this Build Generation. In Next.js jargon, they call it Static Site Generation (SSG), a name I don’t find very appropriate as the content isn’t completely static (it’s built), and the entire site doesn’t have to use this. On a page, this is characterized by exporting a getStaticProps function. Build-time content: This content is created at built time.For example, an image stored at /public/image.png will be served at Static content: These are files put in the /public directory and are served by next.js as they are.To most people, SSR, SSG and ISR are nothing but meaningless acronyms. Fundamentally, Next.js projects can serve content in three different ways: Next.js terminology can be a little befuddling. The difference between Statically and Dynamically rendered content I’ll explore the different options available, their pros and cons. These different methods can be used for automatically generating sitemaps and RSS feeds based on content fetched from a CMS. You can also add custom config file to the end of script.There are many options for generating content with Next.js. Step 3: Add script to package.jsonĪdd next-sitemap script for creating sitemap files as postbuild. sitemap-0.xml, sitemap-1.xml) and index (e.g. SitemapSize: 7000 : When the number of URLs in a sitemap is more than 7000, next-sitemap will create sitemap (e.g. This is the minimal configuration to split a large sitemap. npm i -save next-sitemapĬreate file under your project root. Sitemap.xml and robot.txt for all static/pre-rendered/dynamic/server-side pages will be generated. Use next-sitemap for generating sitemap.xml.
