Interesting the article jumps straight from REST to GraphQL and forgets Falcor[0] - Netflix's alternative vision for federated services. For a while it looked like it might be a contender to GraphQL but it never really seemed to take off... - Source: Hacker News / almost 3 years ago
- obviously netflix with falcor, EVCache and hundreds of other projects. Source: over 4 years ago
I pushed for Falcor over GraphQL in 2016. I still think Falcor was a more elegant core idea, but the implementation, tooling, and community never materialized like it did with GraphQL, and now Falcor is relatively niche and obscure.... Source: about 5 years ago
