Tailor is a Node.js layout service that composes web pages from fragment services using streams, inspired by Facebook's BigPipe. It is part of Project Mosaic and provides middleware for backend composition of pre-rendered markup in front-end microservice architectures.
Use cases
- compose web pages from multiple frontend microservices
- stream fragments for fast time to first byte
- server-side composition of pre-rendered markup for SEO
- enforce performance budgets across page fragments
- render pages gracefully when a fragment fails or times out
- migrate a frontend monolith to microservices
When to choose
- you are adopting frontend microservices and need backend page composition
- you need fast TTFB and streaming HTML from multiple fragment services
- you want a single point to enforce performance budgets and fault tolerance
- you are building on the Project Mosaic ecosystem
When to avoid
- you have a simple single-page app or monolithic frontend
- you need client-side composition or SPA-style rendering
- your stack is not Node.js
- you need a project with frequent recent releases
