nodupdeps (No Duplicate Dependencies)
CLI that ensures that there is only a single version of a dependency installed.
Why?
Configuration
I want to use nconf for my config, but I also want to write tons of small modules that share that configuration. If I'm not super careful about specifying semver compatible versions, and running npm dedupe
, I could easily load two versions of nconf that don't share the configuration.
Optimizing frontend assets
If I'm using webpack, I probably want to try to only bundle in one version of React to minimize the payload. [Webpack does this for you automatically], but if you have different versions it will bundle in both copies. Use nodupdeps
to alert you to possible optimizations.
How?
npm install -g nodupdeps
nodupdeps [packageName ...]
When?
I'd add a post install hook!
package.json
{
...
"scripts": {
"postinstall": "nodupdeps nconf"
},
"devDependencies": {
"nodupdeps": "*"
},
...
}
