npm-install

In the blog post announcing yarn (an alternative npm client) they say, "The easiest way to get started is to run npm install -g yarn ". But if you go to the "install yarn" page in their docs , "npm install yarn" isn't listed on any of the platform-specific installation pages, and it's only offered as the third of three options on the "Alternatives" page. Furthermore when you npm install yarn it prints a deprecation warning, "It is recommended to install Yarn using the native installation method for your environment." So my question is if npm install is the easiest installation method, why isn

I'm working with continuous integration and discovered the npm ci command. I can't figure what the advantages are of using this command for my workflow. Is it faster? Does it make the test harder, okay, and after? From the npm docs : In short, the main differences between using npm install and npm ci are: The project must have an existing package-lock.json or npm-shrinkwrap.json. If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock. npm ci can only install entire projects at a time: individual dependencies

I am trying to run some policing script before any packages are installed. For Example: { "name": "pre-hook-check", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "preinstall": "echo preinstall", "postinstall": "echo postinstall" }, "author": "", "license": "ISC", "dependencies": { "abc": "^0.6.1", "preact": "^8.2.5" } } It seems the pre and post install script on above example only works when I do npm install , but I want that to run every time I try to install anything. For example: Let's say I want to write a
