īut wait, how does it know which version of webpack to run? Isn’t that just looking for a global command?Īctually, no. To do this you need to add a scripts section to your package.json like so. Our main pain point is with the additional path that has to be typed to get to our local installed version, so how do we get around this? Conveniently npm has something we can leverage run-script which allows you to define a command that can be executed, so we can now do this: $> npm run webpack
By relying on globals you have to deal with the problem of what happens if you require but another project you work on is using Well one of them has a broken dependency if you use the global install, and thus it may not work properly. It also means that you can state the version you depend on. So realistically you probably do want to be doing a local install because by doing so you have it added to your package.json and that makes it clear that you depend on webpack. This means that your local install can still be used, it’s just a pain to type the path every time before you run it. If you drop the -g then you still get the executable, but it’s in $PWD/node_modules/.bin. When you use npm install -g it really doesn’t do anything different other than instead of putting the module in your $PWD/node_modules it puts them in the path that node.js is installed to, which (assuming you installed it correctly, or used nvm) will be in your $env:PATH (or other OS equivalent), thus making the command globally available.
This led me to show him how I use globals without relying on global installs. I asked him why he was using npm install -g and he said it was for build tools (gulp/grunt/webpack/etc.) so that you can easily run them.
I was talking with Richard Banks the other day about doing silly things with Docker (because, well I’m known for that at work) and he was saying he wants to create docker containers that contain the global npm modules that he often uses to save installing them using npm install -g. That it is over 3 years old, so the content in here may not be accurate.
Hey, thanks for the interest in this post, but just letting you know
