Effector's tests

ReEffect is designed to be as compatible with usual Effects as possible.

It passes almost all internal Effector's tests, except type tests and one rfc1 test, due to nature of ReEffect.

You can run Effector's tests against ReEffect by doing following:

1 Checkout effector's source code

git clone git@github.com:zerobias/effector.git
cd effector

2 Install ReEffect

yarn
yarn add effector-reeffect

3 Change Flow settings to allow ReEffect package
