I have just started learning React, and Facebook helps in simplifying the initial setup by providing the following ready-made project.
If I have to install the skeleton project I have to type npx create-react-app my-app in command-line.
I was wondering why does the Facebook in Github have npx create-react-app my-app rather than npm create-react-app my-app?
Npx: An npm package runner NPM – Manages packages but doesn\’t make life easy if any.NPX – A tool for executing Node packages .\n\nNPM version 5.2+ bundled with NPX .\n\nNPM by itself does not run any package. It doesn\’t run anything as a matter of fact. If you\’re going to run an package using Npm, you have to specify that package in your package package file. When executables are installed via N PM packages, NPC links to them: NPA.\n\nLocal installs have \”links\” from ./node_modules/.bin/ directory; global installers – i.e., /usr/local/bin) on Linux or at %AppData%/annpm on Windows.\n\nDocumentation you should read.\n\nNPM: Some project: npm install some-package: One may install a package locally on one of these projects.\n\nSay you want NodeJS to run that package from the command line: $ some-package.\n\nAbove will fail. Only globally installed packages can be executed by typing their name only. To fix this, and to have it run, you have to type the local path: $ ./node_modules/.bin/some-package.\n\nBy editing your packages.json file and adding that package in the scripts section: \”name\”: \’whatever\”, \”version\” (scripts): ‘some-package”: “somesome package” ( – package) .\n\nparaphrase: Then run the script with npm run-script (or rpm): Some-package is part of .\n\nNPX: npx will check whether there is a command> in $PATH, or in the local project binaries, and execute it. If you want to implement the locally installed package some-package all you need to do is type: the rpmx .\n\nnpx\’s biggest strength is the ability to run a package that was not previously installed: $ ndx create-react-app my-application: .\n\nFor example, the above example will create a react app boilerplate within the path the command had run in, and ensures that you always use the latest version of an generator or build tool without having to upgrade every time you’re about to use it.\n\nUse-Case Example: npx command may be useful in the script section of a package.json file, when it is obnoxious to define the dependency that may not be commonly used or any other reason: \”scripts\”, \”start\”: [[[email protected]], \”serve\”; \”npmx http-server\”.\n\nCall with: npm run serve .\n\nParaphrase: Related questions: .\n\nPackage installed locally in node_modules? NPM: How can I get ./node/.bin folder? How do you run a js file in npm?
