Static Site Generation (SSG)
Set output: "static" in void.config.ts to prerender all pages at build time:
{
"output": "static"
}When output is "static":
- Pages default to
prerender = trueand are written as HTML files todist/client/. - Use
export const prerender = falsein a page's.server.tsto opt out. That page will be server-rendered on request. - Dynamic pages without
getPrerenderPaths()are implicitly not prerendered (the paths aren't known at build time). - The build output is self-contained and works for direct Cloudflare deployment, self-hosting, or
void deploy.
Per-page overrides
Individual pages can opt out of prerendering:
// pages/dashboard.server.ts
export const prerender = false;Dynamic pages with getPrerenderPaths() are prerendered for the returned param combinations:
// pages/blog/[slug].server.ts
export async function getPrerenderPaths() {
return [{ slug: 'hello-world' }, { slug: 'getting-started' }];
}404 pages
Static builds that prerender at least one page include a default 404.html in dist/client/. To provide your own, add public/404.html or prerender a page at /404.
Fully static Void deployments serve this page for missing URLs with an HTTP 404 status by default. You can override this with routing.notFound. Hybrid deployments handle missing URLs in the Worker.
When hosting dist/client/ yourself, configure your host to serve 404.html with a 404 status for missing pages.
Comparison with edge prerendering
output value | Default prerender | Per-page override | Prerender timing |
|---|---|---|---|
"server" (default) | false | export const prerender = true | Deploy-time (platform ISR) |
"static" | true | export const prerender = false | Build or deploy post-build |
With the default output: "server", use export const prerender = true for deploy-time edge prerendering.
Deployment behavior
void deploy chooses the deployment automatically:
- Fully static: if every page is prerendered and there are no API routes, middleware, cron jobs, or queues, Void deploys as a pure static site with no worker.
- Hybrid: if any pages are not prerenderable, such as dynamic pages without
getPrerenderPaths()or pages withexport const prerender = false, a worker is deployed to handle those routes at runtime. Prerendered pages are still served as static assets.
Relationship to inference.appType: "static"
The inference.appType field describes app type (SPA, static, void), while output controls rendering strategy:
inference.appType: "static" | output: "static" | |
|---|---|---|
| What | Deploy a pre-built static site (no Void plugin) | Prerender a Void app at build time |
| Worker | None (static assets only) | Only if some pages can't be prerendered |
| Use case | VitePress, plain HTML, external SSG tools | Void apps with mostly or fully static content |
