## What it is
Gracejs (formerly koa-grace v2) is a Node.js BFF framework built on Koa 2 that implements an MVC + RESTful architecture for front-end/back-end separation. It serves multiple site applications from a single Node process, with a proxy mechanism for fetching backend API data concurrently and built-in mock support.

## Use cases
- build a BFF layer between frontend apps and backend microservices
- serve multiple sites from one Node.js server with virtual hosts
- render server-side pages by aggregating several REST APIs concurrently
- mock backend API data during frontend development
- structure a Node.js app with MVC controllers and templates

## When to choose
- you need a Koa 2 based front-end/back-end separation framework with MVC routing
- you want one Node process to host multiple site applications
- your pages need concurrent aggregation of multiple backend HTTP APIs
- you want built-in data mocking for development

## When to avoid
- you need a full-stack framework with a real database/ORM layer
- you prefer modern actively evolving frameworks like Next.js or NestJS
- your project is a pure SPA without server-side rendering needs
- you need long-term community support for a small project

## Facets
- artifact type: framework
- maturity: maintenance
