NextJS is a server-side framework for building static and dynamic sites. For
pure static sites, [Webpack loaders](/docs/demos/static/webpack) can preprocess
files and NextJS can build static pages from spreadsheets. For dynamic sites,
NextJS lifecycle methods can read files on the server side.
The [NodeJS module](/docs/getting-started/installation/nodejs) can be imported
from pages or loaded in Webpack loaders.

:::warning Telemetry
NextJS collects telemetry by default. The `telemetry` subcommand can disable it:
```js
npx next@13.4.4 telemetry disable
```
The setting can be verified by running
```js
npx next@13.4.4 telemetry status
```

`@nuxt/content` is a file-based CMS for Nuxt, enabling static-site generation
and on-demand server rendering powered by spreadsheets.

:::caution Telemetry
Nuxt embeds telemetry. According to the developers, it is disabled by default.
To explicitly disable telemetry, the official documentation recommends:
```bash
npx nuxt telemetry disable
```
At the time the demo was last tested, this command did not work. Instead, a
option should be added in `nuxt.config.ts` or `nuxt.config.js` for Nuxt 3 sites:
```js
// ...
// highlight-start
export default defineNuxtConfig({
// @ts-ignore
telemetry: false,
// highlight-end
// ...
})
```
A global setting can be added to `.nuxtrc` in the user home directory:
```ini title=".nuxtrc"
telemetry.enabled=false
```
