Static Page

A static page descriptor is an object with some properties and method :

  • a getPathList function that will return the list of path object that will be used to generate each page. A list of slugs and locale for example. In spirit, this is similar to getStaticPath in Next.js. This method can be omitted if you only need one empty path object (to generate a single page from a pattern without parameters)
  • a pattern string, that will be used for routing. For static pages, this pattern will be used to generate the url of the page from the path object with path-to-regexp. Keep in mind there should be a 1-to-1 correspondance between the path object and the pattern.
  • a getStaticData function that will return the data object for a given path object. In spirit, this is similar to getStaticProps in Next.js This method can be omitted if you only need an empty data object to render the page markup.
  • a getContent function that will return the rendered page as a string given a data object. This is similar to the exported component in Next.js
  • a self URL of the module. Unless you know what you are doing, it should always be new URL(import.meta.url)

A basic example of a static page :

import type * as frugal from '';

type Path = { slug: string };

type Data = {
    title: string;
    content: string;

const store = {
    'article-1': {
        title: 'first article !',
        content: 'this is the first article',
    'article-2': {
        title: 'another article',
        content: 'this is another article',

export function getPathList(): Path[] {
    return [{ slug: 'article-1' }, { slug: 'article-2' }];

export const pattern = '/:slug';

export function getStaticData(
    { path }: frugal.GetStaticDataParams<Path>,
): Data {
    return store[path.slug];

export function getContent({ data }: frugal.GetContentParams<Path, Data>) {
    return `<html>

export const self = new URL(import.meta.url);

Given this page descriptor, frugal will generate two html files: /article-1/index.html and /article-2/index.html. Frugal server is able to handle file named index.html, giving you urls : /article-1 and article-2
