I have untarred node.js from the tar file given on nodejs.org, but when i try executing my js program through node command nothing happens, but on the other hand nodejs command runs executes the file.
So my question is what's the difference between node command and nodejs command as and will it effect my programs as i didn't build from the source code. And i of that is the reason of this discrepancy.
nodejs is a modern javascript-oriented server framework typically used to provide various services and realtime applications, while node is an older framework for transmitting data packets over amateur radio.
Terminal node may mean: Leaf node, a node of a tree data structure that has no child nodes. Lymph node, a terminal lymph node in the lymphatic system.
It is a computer environment the same as command prompt and an easy way to test simple Node. js/JavaScript code and allows to execute multiple javascript codes. we can simply run REPL on the command prompt using node command on the command prompt. Syntax: node.
Node. js or Node is an open-source, cross-platform, JavaScript runtime environment(JSRE) that executes JavaScript code outside of a web browser. npm is a package manager(like Nuget package manager in . NET -Microsoft ) for the JavaScript programming language.
This is highly dependent on many factors. Mainly, it depends on what node
and nodejs
in your shell actually are. You can check this using type node
/ type nodejs
and/or which node
/ which nodejs
(or perhaps whereis
). This also depends on the OS and the shell.
My guess is that which -a node
will yield /usr/sbin/node
which is not the nodejs executable and thus why it does not execute your node code. On my system, it is:
/usr/bin/node -> /etc/alternatives/node -> /usr/bin/nodejs
i.e. node
is just a symbolic link to nodejs
, which is the executable.
You can also create this alias yourself so that it overrides whatever node
is for you.
Some of these answers were difficult to understand for me, so I'm going to write the answer that would've helped me.
node
is something like a radio telemetry solving program, they just happened to snag the name node
first. nodejs
is what you're after. So make sure you:
apt-get install nodejs
then, to fix the lame naming issue, create a symlink. A symbolic link between node
and nodejs
.
sudo ln -s /usr/bin/nodejs /usr/bin/node
The first part is the original file placement, and then where it should link to. You could also create an alias in your bash profile, which is also pretty easy.
