What is the difference between node.js runtime and

问题:

I am trying to install node.js by downloading the .exe file, I am confused and stuck on the Node.js setup where in it asks to install node.js runtime or npm package manager so I want to proceed through the installation after knowing fully the difference between the two.

My question is what is the difference between node.js runtime and npm pacakage manager and what are all the features do I get on the two options.

My basic purpose of installing node.js is to compile Typescript, Please help me to understand the features of the two package

回答1:

First of all, it does not ask you to install Node.js runtime OR npm package manager, it offers you to install them both (if you want)

Now, Node.js runtime is basically what will understand your javascript code and execute it to produce a result.

Npm package manager is a tool which will allow you to install third party libraries (other people's code) by using the command line.

npm install express

will install the framework called express for example.

回答2:

• Node and Nodejs are the same. Interchangeable names for the same thing. Unless someone is talking about graph theory, trees or data structures.
• Nvm is a Nodejs version manager. It let's you easily install and switch between versions. It retains globally installed packages for each version.
• Npm is a package manager. It let's you install software (libraries, plugins, frameworks and applications). Typically this software is installed to build Node applications. Sometimes it isn't.

Put more simply. Npm depends on Node. Nvm installs Node.

Node JS

• Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

• Real-Time services (Chat, Games etc)

NPM

• Npm is a package manager. Typically this software is installed to build Node applications.

• It let's you install software (libraries, plugins, frameworks and applications).
