Support for React Router v4

[thinkian]

Hi there. I would really like to use the "module" version of Catalog in my React project, but it is currently incompatible due to your dependency on react-router-scroll which does not support React Router v4. There's currently an open issue there to support it, as well as a fork. I'm not sure if there's an alternative solution until that matter is resolved. Any advice would be appreciated.

Catalog itself depends on react-router v3, so I think we might be out of luck until we change that.
I'm pretty sure Catalog itself doesn't work with react-router v4. AFAIK, webpack will resolve to either one or the other version but there's no way of depending on both in the same setup.

A workaround would be to not rely on any router-specific code in the components documented with Catalog but I'm aware that this may not be an option.

@wereHamster ran into this issue too if I remember correctly. How did you solve that?

[jstcki]

I did some research and contrary to my last message I don't think it should actually be a problem to have both versions co-exist. We have a setup where the app depends on react-router-dom (v4) and Catalog using v3. I'm guessing that what you're seeing is a npm/yarn warning about incorrect peer dependencies but you can ignore that. Or are you running into an actual runtime errors due to react-router-scroll?

[thinkian]

It's not just the npm warning about peer dependencies. There's an actual runtime error:

./~/react-router-scroll/lib/StateStorage.js Module not found: Error: Can't resolve 'history/lib/DOMStateStorage'

[wereHamster]

Can you attach the output from npm ls?

For reference here's mine (npm v5.4.2):

npm ls history

I'm confused by this line: UNMET PEER DEPENDENCY [email protected]. react-router is not a peer dependency of catalog, it's a proper dependency. Which version of npm or yarn did you use to install the dependencies?

[thinkian]

I'm using npm v3.10.10.

[jstcki]

Is it an option for you to upgrade to npm v5 or yarn? That would probably solve your problem.

[thinkian]

Unfortunately it isn't an option for me to upgrade to npm v5 or yarn at this point. Is there an alternate solution for this issue?

[jstcki]

Since this is really a dependency issue, I don't think there's a reliable way to fix this. npm v3's installs are non-deterministic, and the order in which you install modules produces different results. The only way to get a reliable-ish install is removing node_modules and running a fresh npm install.

Maybe installing Catalog in its own subdirectory could work but I'm not too sure, e.g.:

your-app/
+--catalog/
|  +--node_modules/
|  +--index.js
|  +--package.json (with catalog dependency)
|  +--...
+--node_modules/
+--package.json (with react-router@4)

[thinkian]

I can certainly give that a shot. Will that work using Catalog as a standalone npm module import?

[jstcki]

If imported from within the subdirectory (e.g. catalog/index.js) it might work.
