Falcor is a JavaScript library that lets you represent all remote data sources as a single virtual JSON graph model, fetching data efficiently with JavaScript-like path syntax. It transparently handles network communication, batching and de-duplicating requests, with a Router for building Virtual JSON resources on the server.

Use cases

• fetch data efficiently from multiple backend sources as one model
• reduce network requests by batching and de-duping data fetches
• serve a virtual JSON graph endpoint from an express server
• access remote data with the same code as in-memory data
• build a Netflix-style application data layer
• retrieve only the data paths needed on demand

When to choose

• your app pulls data from many backend services and you want one unified client-side model
• you want automatic request batching, de-duping, and path-based data retrieval
• you prefer a data-driven API where the shape of the data defines the interface
• you're building a rich single-page app with complex, interconnected data

When to avoid

• you want a modern, actively evolving ecosystem - Falcor development has slowed and GraphQL is the mainstream alternative
• you need simple REST endpoints without a virtual graph abstraction
• your team is unwilling to learn Falcor's JSON Graph path syntax and Router model
• you rely on a large community with many third-party integrations
