2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

You need both pixman and cairo, which you can find here: http://cairographics.org/releases/

Pixman configure:

../pixman-0.32.4/configure --prefix=/root/prefix --disable-libpng --disable-gtk

Cairo configure:

PKG_CONFIG_PATH=/root/prefix/lib/pkgconfig ../cairo-1.12.16/configure --prefix=/root/prefix --enable-xlib=no --enable-xcb=no --enable-xcb-shm=no --enable-win32=no --enable-quartz=no --enable-script=no --enable-ft=no --enable-fc=no --enable-ps=no --enable-pdf=no --enable-svg=no --enable-gobject=no --enable-trace=no --enable-interpreter=no --enable-png=no

Problem

There has been no progress in working towards a single cohesive story for path resolution between Servers and Web. Notable discussion points relevant to this are:

1. Node has a path searching algorithm.
2. Web has not been able to gather support for any of the following:
   1. Build tooling as part of UX expectations (lack of interest)
   2. Smarter static web servers (lack of interest). PoC example at https://github.com/bmeck/esm-http-server
3. A resolve based hook. (interest shown with desire for ~6 months of userland experimentation)

// This bug has already been reported to clarify the ES6 spec:
// https://bugs.ecmascript.org/show_bug.cgi?id=2837
//
// I think it still needs to be reported to FF.
// 
// Documenting here for completeness and for relationship to
// the other bugs here.
