Topic: React in both dependancy & peerDependancy, multiple react version errors

mpcooke4 pro asked 3 years ago

This may be related to my own misunderstanding of how npm packages work but I'm a bit confused. I am including mdbreact using the git URL for the pro version ( in my package.json.

Previously I had the react package I wanted installed specified in my package.json too, upon a recently npm update react started complaining about multiple versions of react. I am not sure why because mdbreact and my package.json specific 17.0.1.

I temporarily have it working again by not specifying react in my own package.json although of course there is a complaint by npm that I have the missing peer dependancy react that is required mdbreact.

I think my questions are: Is it intended that mdbreact manages the react version or that I specify it in my own package.json? Does it make sense to have a package specified in mdbreacts dependancy's and peerDependencies in the mdbreact package.json? (especially given that react hates having multiple versions installed)

You can try to place react in both peerDependencies and devDependencies. Placing it in dependencies (without peer or dev) will cause multiple versions of React to be installed.

Command npm dedupe can also be helpful - it removes recursively unnecessary copies of dependencies (including React) :)

Keep coding,
