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
