Node.js allows you to run javascript in the Terminal as appose to a regular browser which makes for a modern workflow in web development, with both node.js installed and a package manager called npm (Node Package Manager) also installed, which can manage other packages that work with node.js, one of the main ones being grunt.js for a web.
In this section, you will get SQL Server 2017 running on Docker. After that, you will install the necessary dependencies to create Node.js apps with SQL Server locally on your Mac.
Step 1.1 Install SQL Server
- In order to run SQL Server on your Mac, we are going to use the SQL Server on Linux Docker Image. For this, you need to install Docker for Mac.
- Configure at least 4GB of memory for your Docker environment, also consider adding multiple cores if you want to evaluate performance. You can do this in the Preferences - Advanced option on the menu bar.
- Next, start a new Terminal prompt and use the following commands to download and start the SQL Server on Linux Docker image. Make sure to use a strong password with special characters.
You now have SQL Server running locally in Docker! Check out the next section to continue installing prerequisites.
Step 1.2 Install Homebrew and Node.js
- Install Homebrew.
- Restart the terminal session.
- Install Node.js
You now have Node.js installed! The next section will walk you through getting the tools to interact with your database.
Step 1.3 Install the ODBC Driver and SQL Command Line Utility for SQL Server
SQLCMD is a command line utility that enables you to connect to SQL Server and run queries.
After installing SQLCMD, you can connect to SQL Server using the following command:
This how to run a basic inline query. The results will be printed to the STDOUT.
You have successfully installed SQL Server Command Line Utilities on your macOS machine!
You now have everything you need to start writing Node.js apps with SQL Server!

Introduction
Node.js is a run-time environment used for executing JavaScript outside the browser. Npm is a JavaScript package manager commonly used for installing packages for Node.js.
In this article, you will learn how to install Node.js and npm on Mac or Linux. You will also learn how to verify the installation, run Node.js code, and how to update Node.js and npm.
When you’re finished, you’ll be able to run Node.js code on Mac or Linux computer.
Prerequisites
To follow this tutorial successfully, you’ll need the following:
- Internet access to download Node.js.
- Basic knowledge of how to use the terminal.
Step 1 — Install Node.js and npm on Mac or Linux
There are a couple of ways to install Node.js on Mac or Linux. The most recommended method and also my favorite method to install Node.js and npm is to use Node Version Manager(nvm).
Using nvm has the following benefits:
- It allows you to install multiple versions of Node.js.
- It makes it easy to switch between the versions.
- Updating node.js is a breeze with nvm.
So let’s now install nvm. Copy and paste the command below into your terminal.
Info: If your on Mac, open your
~/.bash_profile
or create a new one if the ~/.bash_profile
file does not exist. Make sure you add source ~/.bashrc
in the file and save.Now let’s verify if
nvm
was installed successfully.Your terminal should display the current version of nvm. At the time of writing, the current version is 0.35.2. So this is the output I got.
Note: On Linux, if you get
nvm: command not found
or no feedback, close your terminal and open a new terminal and enter the nvm --version
again. If you using ssh to access linux, you might need to restart your session.Tip: On Mac, if you are having any issues with the
nvm
command not working, check out this linkLets now install Node using nvm’s install command.
Once installed, set the installed version as the default.
Info: You need to set the default version because nvm forgets the node version in a new terminal session. You can learn more about the issue here.
Step 2 — Verify Node.js and npm installation
![Install node js windows Install node js windows](/uploads/1/2/6/7/126729124/783682491.png)
Verify if Node.js and npm were successfully installed.
Type
node -v
. It will display the current Node.js version.Type
npm -v
to display the current npm version.Your output should look similar to mine. Note that the versions will be different since you might be reading this tutorial when new versions came out.
Running Node.js Code on Mac or Linux
There are two ways to run Node.Js code:
- Node.js REPL
- Running Node.js scripts on the terminal
Node.js REPL
REPL stands for Read-Evaluate-Print-Loops. It is an interactive shell that allows experimentation of JavaScript code. It works the same way as the web browser console.
To access the Node REPL, type
node
in the terminal.The REPL prompt will be opened where you can enter the JavaScript code.
The
>
sign is there to let you know that the code entered will be immediately evaluated when you press enter.To exit out of the REPL, type
.exit
or press CTRL+D
once. You can also exit out by pressing CTRL+C
twice.Running Node.js Scripts on the Terminal
This method is the one that is commonly used to run Node. You will write Node.js code in a file with an extension of
.js
and run it in the terminal using the node
command.Let’s see this in action by creating a directory named
node.js
in our home directory.mkdir
is a command used for creating directoriesLet’s go into the
nodejs
directory.Your terminal should now show you are in the
node.js
directory.Create a file
first-program.js
. For simplicity’s sake, we will use Nano which is a terminal text editor.Enter the following code in
first-program.js
in the Nano editor.Hold CTRL+O and then press
enter
to save the file.Exit out of the editor by holding
CTRL+X
.Let’s now run the code in
first-program.js
:Your output should look like below.
I hope you have understood how to run Node.js code on your Mac or Linux system.
Next, we are going to learn how to update Node.js and npm using nvm.
How to Update Node.js and npm using nvm
To update to the latest version Node.js and npm. Type the following:
To update to the latest LTS(Long Term Support) version. Type the following:
