Recently I tried installing my Node packages with Yarn. It works great and it's a lot faster than NPM. Yarn automatically generates yarn.lock . We already have NPM shrinkwrap ( npm-shrinkwrap.json ). Is there any difference between them? Does yarn.lock has any advantage over npm-shrinkwrap.json? Aurora0001 The yarn.lock file is quite similar to other package managers' lock files, especially Rust's Cargo package manager, which has Cargo.lock . The idea of these lock files is to represent a consistent set of packages that should always work. npm stores dependency ranges in the package.json file,

How can I uninstall yarn? I've used it for a react-native project and now whenever I move the code out of index.ios.js or index.android.js it throws an error so I'd like to just use npm but whenever I initialize a react-native project it defaults to yarn. I tried npm uninstall yarn but that didn't work. Thanks. sospedra Depends on how you installed it : brew : brew uninstall yarn tarball : rm -rf "$HOME/.yarn" npm : npm uninstall -g yarn ubuntu : sudo apt-get remove yarn && sudo apt-get purge yarn centos : yum remove yarn windows : choco uninstall yarn Didn't see the answer that worked for me,

I've got an existing code base in which Vue.js has performance problems. I also see this notice in the browser console: so I guess an easy fix could be to put Vue into production mode. In the suggested link I try to follow the instructions for webpack. We're on Webpack version 2.7 (current stable version is 4.20). In the instructions it says that in Webpack 3 and earlier, you’ll need to use DefinePlugin : var webpack = require('webpack') module.exports = { // ... plugins: [ // ... new webpack.DefinePlugin({ 'process.env.NODE_ENV': JSON.stringify('production') }) ] } So in my package.json I've

I have a Rails project that we converted from Rails 5.0 to Rails 5.1.0. When I try to precompile the assets, I get the following error message: Yarn executable was not detected in the system. Download Yarn at https://yarnpkg.com/en/docs/install Everything I read from an internet search says yarn and webpacker comes with Rails 5.1. I get the following from check the rails version. $rails --version Rails 5.1.0 How do I fix this? I'd also like to know what is happening. Rails 5.1 comes with SUPPORT for yarn and webpack, but you need to install them yourself. Yarn is a package manager and webpack

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

I want to ask what is your favorite package manager for JS ? I saw some articles about yarn and npm. But I am not sure what can be better for me. I just start learning JS. Right now difference between yarn and npm is for me like difference between brands of cola. Milos Mosovsky There were times when we had only npm but it had so many issues with resolving dependencies and caching that another tool has born ( yarn ). Usually it was using local cache to resolve dependencies and it was crucial for example while running CI jobs which are almost always ran in same environment and high bandwidth is

If my package has these dependencies { "name": "my-package", "dependencies": { "foobar":"~1.0.3", "baz":"2.0.9" } And the foobar package has these dependencies { "name": "foobar", "dependencies": { "baz":"^2.0.0" } and the most recently released version of baz is 2.1.0 , the first run of yarn will install baz@2.1.0 in foobar/node_modules . How do I force yarn to use the baz@2.0.9 package for foobar ? My understanding is that this would be possible using npm shrinkwrap (a la this question ). The summary of my question probably is: Yarn creates repeatable, deterministic installations, but how do
