Wow! Thanks @glennr!

@alexfedoseev @robwise, let's chat later today about how this compares to what we were planning for our internal project.

Thanks again @glennr!

@robwise JS tests will eventually go into the react_on_rails generator.

[glennr]

@justin808 you're welcome - I hope it's useful. Either way I'm super interested in knowing what test stack you guys end up going with on your internal project.

[glennr]

I found an issue on this branch:

npm ERR! peerinvalid The package react@0.14.0 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer react-bootstrap@0.27.1 wants react@>=0.14.0
npm ERR! peerinvalid Peer react-addons-test-utils@0.14.1 wants react@^0.14.1
npm ERR! peerinvalid Peer uncontrollable@3.1.3 wants react@>=0.11.0
npm ERR! peerinvalid Peer react-overlays@0.5.0 wants react@>=0.14.0

I'll push a fix for this.

@glennr I'm trying to run this, but it looks like a few more hours before we can update all.

cd client 
rm npm-shrinkwrap.json
npm-check-updates -u
npm install
npm prune
npm shrinkwrap

See #35.

@justin808 I indeed forgot to npm-shrinkwrap after adding those deps (I recalled something to that extent, but couldn't find it in the Readme - I found it on your blog entry this morning).

So there's a couple of issues on this branch now

• incompatibility of react-addons-test-utils (try 0.14.0 not 0.14.1)
• resolve babel incompatibility (after shrinkwrap)

I'm on a terribad 3g connection at the moment, so npm install has been a 'special' experience for me all morning. I'll check back in another few hours when npm install has hopefully completed :-)

[glennr]

I had to upgrade react to 0.14.1 to be compatible with react-addons-test-utils. All specs pass OK.

I think a lot of my issues were to do with my npm version, which I upgraded;

glennr@Django client[gr_mocha_tests*] % npm -v
2.14.7
glennr@Django client[gr_mocha_tests*] % npm install npm -g
/usr/local/bin/npm -> /usr/local/lib/node_modules/npm/bin/npm-cli.js
npm@3.3.10 /usr/local/lib/node_modules/npm
glennr@Django client[gr_mocha_tests*] % npm -v
3.3.10

@justin808 - WRT the babel incompatibility - I had to run 'npm prune --production' to remove all local dev deps before npm shrinkwrap would work. Is that right?

[glennr]

@justin808 - I've left the relevant unsquashed commits so its easier for you to review - but happy to squash them once you've given the +1

[robwise]

We should have this in there regardless! Good catch!

[glennr]

Thanks!

I just realized npm-debug.log* will suffice. All I wanted to do is ignore those timestamped npm-debug.log.201501...etc files

@glennr if you can take care of this, that would be great. I want to leave you in as the author.
