The "Boring" Part of Building a SaaS
We all love building the product—the dashboards, the Stripe integration, the animations.
But if you are launching a company in Europe (specifically France, UK, or Switzerland), you hit a wall right before launch: Compliance.
You legally need a "Legal Mentions" (Mentions Légales) modal that displays:
- Your Corporate ID (SIRET / VAT / CRN)
- Hosting Provider details (Address + Contact)
- Intellectual Property disclaimer
Most devs hardcode this into a or a static page. Then, when the office moves or the hosting changes, you have to hunt down the code.
The Solution: Data-Driven Compliance
I got tired of rewriting this for every client launch in Paris and London. So, I extracted it into a reusable Next.js Component that drives the legal text from a simple JSON file.
It’s open-source, and you can grab it today.
- The Data Structure (legal-data.json)
Instead of hardcoding text, we define the entity. This supports i18n out of the box (switching between EN, FR, and RU context).
{
"company": {
"trade_name": "MY STARTUP",
"legal_name": "My Startup Ltd",
"siret": "993 637 xxx",
"vat_number": "FR XX 993 637 750",
"address": "59 rue de Ponthieu, 75008 Paris",
"contact_email": "[email protected]"
},
"hosting": {
"provider": "Vercel Inc.",
"address": "340 S Lemon Ave, Walnut, CA 91789, USA"
},
"translations": {
"en": { "publisher": "Website Publisher", "hosting": "Hosting Provider" },
"fr": { "publisher": "Éditeur du Site", "hosting": "Hébergeur" }
}
}
- The Component
The component simply consumes this data. It handles the boring formatting (like making sure the SIRET number is readable) so you don't have to.
Features:
✅ Zero Dependencies: No heavy libraries, just React/Next.js.
✅ Multilingual: Supports EN/FR/RU structure instantly.
✅ EU Compliant: Formatted specifically for French/UK regulations (Loi LCEN).

I’ve open-sourced the boilerplate on GitHub. Feel free to fork it, star it, or use it in your next freelance project.

Why did I build this?
I help Global Founders (International entrepreneurs in London/Zurich/Paris) launch their tech stacks without getting bogged down in admin.
When you're starting a business, you should focus on customers, not formatting VAT numbers in a footer.
