Borrissol configuration reference: Astro, site, and config

Borrissol’s project-wide settings are spread across three files that each own a clearly defined domain: astro.config.mjs controls the framework, adapters, integrations, routing and redirects; src/config/site.ts centralises every SEO token and business detail that feeds structured data; and src/config.ts holds the WhatsApp deep-link utility consumed by all four language variants of the site. Keeping these three files in sync is the first step before going live or after any rebrand.

`astro.config.mjs`

The root framework config. It declares the deployment target, trailing-slash policy, 301 redirects, all integrations, and the i18n routing strategy.

astro.config.mjs

// @ts-check
import { defineConfig } from 'astro/config';
import sitemap from '@astrojs/sitemap';
import netlify from '@astrojs/netlify';
import keystatic from '@keystatic/astro';
import react from '@astrojs/react';
import markdoc from '@astrojs/markdoc';

export default defineConfig({
  site: 'https://borrissol.com',
  adapter: netlify(),
  trailingSlash: 'never',
  i18n: {
    defaultLocale: 'ca',
    locales: ['ca', 'es', 'en', 'fr'],
    routing: { prefixDefaultLocale: false },
  },
  // ... redirects, integrations (see sections below)
});

`site`

site: 'https://borrissol.com'

The canonical origin. Astro uses this to generate absolute URLs in the sitemap, canonical tags, and Open Graph meta. Update this value if the domain ever changes.

`adapter`

adapter: netlify()

Provided by @astrojs/netlify (^7.0.12). All pages are statically prerendered except the Keystatic admin routes, which require SSR. The adapter wraps those in Netlify Functions automatically with no extra configuration.

`trailingSlash`

trailingSlash: 'never'

Ensures all URLs are canonical without a trailing slash (e.g. /es/tallers not /es/tallers/). The Netlify adapter enforces this at the edge.

`redirects`

All redirects are declarative 301s in the Astro config. They fall into two groups: Legacy /ca/* → /* — Catalan is the default locale served at root (no /ca/ prefix). Any legacy URLs with the /ca prefix get permanently redirected to strip it. /<lang>/blog → /blog — The blog is intentionally Catalan-only. Non-Catalan blog URLs redirect to the Catalan blog so shared links and old bookmarks still resolve.

redirects: {
  // /ca/* → / (legacy prefix removal)
  '/ca':             { status: 301, destination: '/' },
  '/ca/gallery':     { status: 301, destination: '/gallery' },
  '/ca/press':       { status: 301, destination: '/press' },
  '/ca/blog':        { status: 301, destination: '/blog' },
  '/ca/blog/[slug]': { status: 301, destination: '/blog/[slug]' },

  // /<lang>/blog → /blog (blog is CA-only)
  '/es/blog':        { status: 301, destination: '/blog' },
  '/es/blog/[slug]': { status: 301, destination: '/blog/[slug]' },
  '/en/blog':        { status: 301, destination: '/blog' },
  '/en/blog/[slug]': { status: 301, destination: '/blog/[slug]' },
  '/fr/blog':        { status: 301, destination: '/blog' },
  '/fr/blog/[slug]': { status: 301, destination: '/blog/[slug]' },
},

Astro requires redirect destinations to match real routes. Wildcards like /ca/* do not work in Astro’s redirects object — each sub-route must be listed explicitly.

`integrations`

integrations: [
  sitemap({
    // Emit hreflang cross-references between language variants of each page.
    // Keys must match the locale codes in `i18n.locales`.
    i18n: {
      defaultLocale: 'ca',
      locales: {
        ca: 'ca-ES',
        es: 'es-ES',
        en: 'en-US',
        fr: 'fr-FR',
      },
    },
    // Defensive filter: exclude any stray /ca routes from the sitemap.
    filter: (page) => !page.includes('/ca'),
  }),
  react(),
  markdoc(),
  keystatic(),
],

Integration	Package	Purpose
`sitemap()`	`@astrojs/sitemap ^3.7.3`	Generates `sitemap.xml` with `hreflang` `rel="alternate"` entries for all four locales. Mirrors the hreflang tags already in each page’s `<head>`.
`react()`	`@astrojs/react ^5.0.7`	Required by Keystatic’s admin UI, which is a React application. No React is used on public-facing pages.
`markdoc()`	`@astrojs/markdoc ^1.0.6`	Renders blog post bodies written in Markdoc (a superset of Markdown).
`keystatic()`	`@keystatic/astro ^5.0.6`	Mounts the Keystatic admin at `/keystatic` and handles the Git-backed CMS API routes.

`i18n`

i18n: {
  defaultLocale: 'ca',
  locales: ['ca', 'es', 'en', 'fr'],
  routing: {
    prefixDefaultLocale: false,
  },
},

Key	Value	Meaning
`defaultLocale`	`'ca'`	Catalan content is served at root (e.g. `/tallers`).
`locales`	`['ca', 'es', 'en', 'fr']`	The four supported languages.
`prefixDefaultLocale`	`false`	Catalan URLs have no language prefix; Spanish, English and French are prefixed (`/es/`, `/en/`, `/fr/`).

`src/config/site.ts`

This file exports the SITE constant — a single object that every SEO and structured-data component reads from. It is the single source of truth for the business name, address, contact details, hours, and social links.

Key fields

Field	Value	Used by
`url`	`https://borrissol.com`	Canonical URLs, Open Graph, JSON-LD
`locale`	`es_ES`	Open Graph `og:locale`
`logo`	`/images/borrissol-logo-b-512.png`	JSON-LD `Organization.logo` (512×512px per Google spec)
`defaultOgImage`	`/og-default.jpg`	Fallback `og:image` for pages without a cover photo
`business.type`	`LocalBusiness`	JSON-LD `@type` — controls which Google rich results are eligible
`business.geo`	`41.5373926, 2.4466578`	JSON-LD `geo` node — places the business in Google’s local map pack
`business.openingHours`	`['Mo-Sa 09:30-13:30', 'Mo-Sa 16:30-20:30']`	JSON-LD `openingHours` — shown in Knowledge Panel
`business.sameAs`	Instagram, TikTok URLs	JSON-LD `sameAs` — reinforces entity disambiguation

Update SITE before going live after any rebrand or change of address. The object feeds Seo.astro, all JSON-LD structured data blocks, and the Open Graph tags on every page — stale values will be indexed by search engines.

`src/config.ts`

A minimal module that exposes the WhatsApp contact number and the waHref URL builder.

src/config.ts

const WHATSAPP_BASE = 'https://wa.me/34673247520';

export const WHATSAPP_HREF = WHATSAPP_BASE;

export const waHref = (text: string) =>
  `${WHATSAPP_BASE}?text=${encodeURIComponent(text)}`;

`waHref(text)`

Builds a WhatsApp deep link with a pre-filled message. Every CTA button and the floating WhatsApp FAB call waHref() with a locale-specific message string fetched from src/i18n/ui.ts. The resulting URL opens the WhatsApp app (or web) with the message pre-composed, ready to send. Example:

import { waHref } from '../../config';

const href = waHref('Hola! Vull apuntar-me a un taller de tufting.');
// → 'https://wa.me/34673247520?text=Hola%21%20Vull%20apuntar-me%20a%20un%20taller%20de%20tufting.'

Environment variables

No .env file is required. All project configuration is in code. Keystatic Cloud credentials (used for authenticating the /keystatic admin in production) are configured through the Keystatic Cloud dashboard and injected by Netlify at build/runtime — they are never stored locally.

Node version

The project requires Node ≥ 22.12.0, declared in package.json and pinned in netlify.toml:

netlify.toml

[build.environment]
  NODE_VERSION = "22.12.0"

Use nvm or fnm locally to match this version.

`.npmrc`

.npmrc

legacy-peer-deps=true

legacy-peer-deps=true is required to resolve a peer dependency conflict between @keystatic/astro 5.0.6 and Astro 6. Without it, npm install exits with an ERESOLVE error. Do not remove this flag until the upstream conflict is resolved in a future Keystatic release.
