From 39a725ae2152552117da62614d08efd907cc7ab1 Mon Sep 17 00:00:00 2001 From: "Kent C. Dodds" Date: Tue, 9 Jan 2018 09:53:42 -0700 Subject: [PATCH] add experimental babel-plugin-macros support (#3675) * add experimental babel-plugin-macros support closes #2730 This will remain undocumented until the brave have tried it in the wild. **Test Plan:** There's currently no established way to test changes to `babel-preset-react-app`. But I did create [`unmaintained-react-scripts-babel-macros`](https://www.npmjs.com/package/unmaintained-react-scripts-babel-macros) [a while back](https://github.com/facebookincubator/create-react-app/issues/2730#issuecomment-328153982) and it worked well. * Pin the version --- packages/babel-preset-react-app/index.js | 3 +++ packages/babel-preset-react-app/package.json | 1 + 2 files changed, 4 insertions(+) diff --git a/packages/babel-preset-react-app/index.js b/packages/babel-preset-react-app/index.js index d90fb6af50b..d1639dd2161 100644 --- a/packages/babel-preset-react-app/index.js +++ b/packages/babel-preset-react-app/index.js @@ -7,6 +7,9 @@ 'use strict'; const plugins = [ + // Experimental macros support.
