package.json

I found these properties prefixing underscore in package.json. What are they used for? why prefixing underscore on properties? "_from": "react-scripts@0.9.3", "_id": "react-scripts@0.9.3", "_inCache": true, "_location": "/react-scripts", "_nodeVersion": "6.0.0", "_npmOperationalInternal": { "host": "packages-18-east.internal.npmjs.com", "tmp": "tmp/react-scripts-0.9.3.tgz_1488303928068_0.6415497597772628" }, "_npmUser": { "name": "gaearon", "email": "dan.abramov@gmail.com" }, Those are meta data reserved for package registries. All properties beginning with _ or $ are reserved for package

i have an angular 4 app and i want to run it on ubuntu. i copied all project files , package.json and package-lock.json to a folder in winscp but i didn't copy node_modules! now when i run npm install, i get the errors like this: > node-sass@4.7.2 install /home/ubuntu/cms/node_modules/@angular/cli/node_modules/node-sass > node scripts/install.js Unable to save binary /home/ubuntu/cms/node_modules/@angular/cli/node_modules/node-sass/vendor/linux-x64-57 : { Error: EACCES: permission denied, mkdir '/home/ubuntu/cms/node_modules/@angular/cli/node_modules/node-sass/vendor' at Object.fs.mkdirSync

I want to minify all .html files in a folder (and any folders within) using npm run script. Ideally, all .html files should be overwritten (if that's not possible, a new folder is acceptable). It is assumed that there will be non-HTML files in the input folder. npm library minimize works only on per-file but not on folders. Another npm library html-minifier does accept folder as input, but fails if there are any non-HTML files present in the input folder: html-minifier --input-dir ./test1 --output-dir ./test2 --html-5 --collapse-whitespace I need this to minify my static website's HTML files.

I am currently trying to create a docker container for a node.js project that contains a local dependency. This seems to cause an issue with docker so as a workaround I am trying to just copy the local dependency folders and just ignore their dependency entries in the package.json file. Is there a way to specify dependencies I would like to ignore and have npm install run and skip those enties? That can be done using devDependencies The npm modules which you require only to develop, e.g.: unit tests, Coffeescript to Javascript transpilation, minification etc,make the required module a

I am coming across a very bizarre error when installing packages for my webpack/reactjs application. I am currently trying to install npm install copy-webpack-plugin --save dev The build/start scripts fail and the following error is shown in the terminal: Unsupported platform for inotify@1.4.1: wanted {"os":"linux","arch":"any"} (current: {"os":"darwin","arch":"x64"}) This means absolutely noting to me and I cannot find any clear explanations online.I do not know why inotify is needed or when/where it has been installed. Package.json scripts: "scripts": { "start": "node server.js", "build":

How do I add multiple NODE_PATH in package.json? I want to have these multiple paths: NODE_PATH=./ NODE_PATH=./modules/ or NODE_PATH=./lib NODE_PATH=./modules/ package.json: { "name": "my-app", "description": "env", "repository": "https://github.com/xxx.git", "scripts": { "dev": "NODE_PATH=./lib NODE_PATH=./ node server.js", "start": "cross-env NODE_ENV=production NODE_PATH=./ NODE_PATH=./modules/ nodemon --exec babel-node --presets es2015 server.js" }, "dependencies": { "cross-env": "^5.0.5", "express": "^4.15.4" }, "license": "MIT" } server.js: 'use strict' import express from 'express'

I can't seem to get the outDir flag working when used in package.json . Directory structure is pretty simple: tsconfig.json at the root level, together with a src/ directory and a single index.ts file plus other directories representing other modules. When running the tsc command on the index file, it creates a new one beside it instead of in the build directory. What am I doing wrong? My tsconfig: { "compilerOptions": { "outDir": "build" } } My npm build script: "build": "tsc src/index.ts" I'm calling the script from the root dir of the project. Interestingly, running the same script with an

What does "dev" true means in package-lock.json file? In my case it is automatically updated when I perform npm operations. How can we remove it? Kyle Reynolds From the npm docs at https://docs.npmjs.com/files/package-lock.json If true then this dependency is either a development dependency ONLY of the top level module or a transitive dependency of one. This is false for dependencies that are both a development dependency of the top level and a transitive dependency of a non-development dependency of the top level. I think this paragraph tries to illustrate how the package dependency's dev:
