# Node.js

## Node.js and npm
## Node.js and npm installation

Starting from Fedora 24, npm is a part of Node.js package and does not need to be installed separately. Therefore, to install both npm and Node.js, you need to run:

```
$ sudo dnf install nodejs
```

In case you are running Fedora 23, you should run:
This will install V8 Javascript Engine, Node.js runtime and npm package manager and their dependencies. Versions present in repositories are usually current or to-be (in Rawhide) Node.js LTS releases, including npm and V8 engine that come with them.

You can check the available versions with:

```
$ sudo dnf install npm
$ dnf info nodejs
$ dnf info nodejs --enablerepo rawhide

Rawhide repository is not included in basic Fedora install AFAIK, so this wouldn't work.

This will soon work with just --releasever=30 instead of --enablerepo rawhide, right?

```

This will install V8 Javascript Engine, Node.js runtime and npm package manager and their dependencies. Versions present in repositories are usually current or to-be (in Rawhide) Node.js LTS releases, including npm and V8 engine that come with them.
## Yarn

If you wish to install Node.js v4:
[Yarn](https://yarnpkg.com/en/) package manager is available since Fedora 29. You can install it by running:

```
$ sudo dnf install nodejs --releasever=24
$ sudo dnf install nodejs-yarn
```

If you need Node.js v6:
Because of conflicts with other packages, yarn has to be used in the following manner:

```
$ sudo dnf install nodejs --releasever=25
$ nodejs-yarn add request

I'd add a comment describing what is done, like so:

# Install package request using nodejs-yarn
[ . . ]
# Install package request using yarnpkg

$ yarnpkg add request
```

If you still wish to use `yarn` instead of `nodejs-yarn`, the best way is to use bash alias.

Can you include the alias example, please?
