![]() ![]() Because it's very common that a project calls locally installed executables, you can use them in the scripts section of the package.json without prefixing them with node_modules/.bin. Ĭommand line tools or generally packages with executables, such as webpack, are available in node_modules/.bin and in order to execute them, they have to be either in your shell's PATH or called directly. If you want to add it as a dependency use npm install -save examplePackage or as a devDependency with npm install -save-dev examplePackage. Note: npm install examplePackage does not add examplePackage to your package.json, it simply installs it. After that you can correctly import those modules. Instead you need to run npm install, this will install all listed dependencies in package.json. As you've noticed you can specify the dependencies in the package.json, but node itself does not do anything with that information. It only looks on your hard drive, specifically in the node_modules directories as mentioned above. How does node know to search thru either your project for a package or your hard drive? Probably the biggest advantage is that you can easily share your project with others and you can be sure that it will work for them (assuming a compatible Node.js version). Although it would be possible to just install all dependencies in /, there are many advantages of having project specific dependencies. That indeed means that you can import a package, that has been installed in /, from anywhere on your file system. And so on until the module was found or the root of the file system is reached. If the module is not found in that directory, it moves to the parent directory and checks its node_modules directory. If it isn't a core module it starts looking in node_modules of the current directory. When you import a module in Node.js with require('examplePackage') it first checks if it's a core module (e.g. Npm install examplePackage will install the package in node_modules of the current directory. If that's not what you expect, you probably got it wrong from the beginning.Ģ,630 9 9 gold badges 27 27 silver badges 61 61 bronze badges 1 Answer With local copy it just a javascript lib, and need npm command to run each compile, also bring more work I think. If you have similar projects, you can either copy them around or create a git branch to achieve the result. And certainly lots of CLI tools are working as the same way webpack does, reading each individual configuration files per project, not globally. Installing global package is not recommended if you have multiple projects to run. You probably had it wrong regarding how node.js works. What I expected is if I install webpack globally, I can run 'webpack' command at the project root folder, then it will read webpack-config.js file and execute full compile logic, in that way I can share the same webpack copy across different projects and make the compile much easy. Lot's of projects are using it to generate a complex website/web app, not just compile one file at a time. webpack is a powerful tool but highly depends on how you use it. This project increases your income/productivity too.Īnd seems it only compile one file each time not full compile, that may not good for big project which contain many export files. If you use webpack for a serious task, and you'd like us to invest more time on it, please donate. Most of the core team members, webpack contributors and contributors in the ecosystem do this open source work in their free time. You need to *stop* thinking about global variables, and *start* thinking about how you can code *correctly*. When you use Webpack, the *hardest* thing is that you need to start thinking about your JavaScript differently.The global namespace of CSS makes it very difficult to be confident that a change to your CSS will.
