From b95e5506d21d6390e0f936a78f9a5093f27b9ac0 Mon Sep 17 00:00:00 2001 From: Miel Truyen Date: Tue, 14 Apr 2020 11:54:30 +0200 Subject: [PATCH] v0.0.11: Added unit-tests, solved the key={...} problem, updated the build/watch configuration of CSX to be able to build minified and non-minified bundle outputs, as well as a CJS version of lib/ (for consuming in Node-environment, like Jest). The previous tests were renamed to examples, and should still need to be updated. --- .idea/misc.xml | 2 +- .idea/webResources.xml | 2 + README.md | 1 + {tests => examples}/.babelrc | 0 {tests =>
