What is Incremental Static (Re)Generation?
For understanding Incremental Static Generation, let the explanation be guided by a scenario where a page requested by the user was not pre-rendered while statically exporting the website. In such a case, a fallback page is served while the data loads. Further, upon completion of building the page with the fetched data, the page is then cached onto the server. Any user requesting the page then would skip over the fallback and loading stages, and directly see the built page. Superb!
Regeneration is inspired by the concept of stale-while-revalidate, where stale data is refreshed at regular intervals of 'revalidate' seconds. For pages that have staleWhileRevalidateSeconds value configured, they would be re-built after regular intervals of the configured value.

Getting started with ISG in Nuxt.js with Layer0
This section will describe how to implement ISG with Layer0 and Nuxt.js. The steps include configuring a nuxt app with layer0, creating dynamic page and api routes, and finally using layer0 configurations to see ISG in action.
Configuring Nuxt.js app with Layer0
Create a Nuxt.js app by the following command:
- For Choose custom server framework select None
- For Choose rendering mode select Universal (SSR)
In case you already have a nuxt app, just maintain the above configurations and would be good to go.
- Add the Layer0 CLI via:
- In nuxt.config.js, add "@layer0/nuxt/module" to buildModules:
Run the Nuxt.js app locally on Layer0
Run the Nuxt.js app with the command:
Creating dynamic page and api routes
Set up dynamic page routes
Set up dynamic api routes

Example of Incremental Static Generation with Layer0
With Layer0, it's easier than ever to implement Incremental Static Generation for different purposes with different frameworks. The following seeks to implement ISG with Nuxt.js via Layer0.
