Great, so let's finally go on and build an actual web app and local server! To do this quite conveniently we can use the express-generator which is a great command-line tool that creates an application skeleton for us. Otherwise you would be required to write more advanced code like setting up a server instance, configuring a view engine, etc. Web Web Build, deploy, and scale powerful web applications quickly and efficiently.

The Mac App Store opened for business on January 6, 2011 with 1,000 apps. Designers will be happy to know that there is an entire category devoted to Graphic & Design Apps. While some Apps may cross-over into other categories such as Photography, Utilities, and Developer, there is a growing list of Graphic & Design.
A guide to setting up an Apple Mac for DevOps and software development. This is current for macOS 10.14 (Catalina).
Do This First!Log in once, run Software Update, and ensure that the operating system is at the latestpoint release. After all of the updates have been applied, restart the computer.
Log in again and create an Admin user account for your use. If other people will beusing the machine, create Standard accounts for them. Log out of the initial account,and log in to the Admin account that you have just created.
Always log in with this new Admin account. The benefit of leaving the initial accountuntouched is that it ensures that you always have a working account to login with.
Admin accounts have sudo privileges: All Admin accounts on a Mac may use sudo to runcommand-line utilities with administrative (root) privileges.
You should also find an external hard drive. Begin using Time Machine as soon aspossible, as it provides the most easy method for backing up your system.
Configuring a User AccountConfiguring The TrackpadTo make the trackpad behave correctly, ensure that these settings are enabled:
System Preferences > Trackpad > Tap to click
System Preferences > Accessibility > Mouse & Trackpad > Trackpad Options… >Enable dragging
Creating a Private Applications FolderOnce you have logged into your account, create a folder called Applications withinyour home folder. Whenever you are prompted to drag a new applications into the globalApplications folder, put it in this private Applications folder instead. Someapplications have to be installed to global folders, but in most cases you can keep thesystem directories clean by storing third-party products in your private Applicationsfolder.
Securing the Safari BrowserWhether or not you regularly use Safari, you should open it once, and adjust thesettings in case that you use it later.
First, choose Safari > Preferences > General and deselect the option Open 'safe' files after downloading.

Second, go to Safari > Preferences > Search. Decide which search engine that you want to use. Ensure that Safari Suggestions is not enabled.
Then, check the plug-in settings. Go to Safari > Preferences > Security > Plug-in Settings… and review the plug-ins and settings.
Configuring SecurityApple provide quite secure operating systems, but unfortunately convenience has won outover security in a few places. These can easily be corrected by changing a few settings.If you are using a laptop then you should probably make all of these changes as soon aspossible.
Basic SettingsSelect System Preferences > Security & Privacy, and set the following:
Under General, set require a password after sleep or screen saver begins toimmediately
Click Advanced… and select Require an administrator password to accesssystem-wide preferences
Under Firewall, click Turn Firewall On.
Under Privacy, select Analytics and ensure that the options are not enabled.
Disable SpotlightBy default, Spotlight sends queries to Apple. Unless you want this feature, turn it off.
Select System Preferences > Spotlight > Search Results, and ensure that Spotlight Suggestions is not enabled.
Enable File Vault NOWCurrent versions of macOS include File Vault 2, a full-disk encryption system that haslittle in common with the much more limited File Vault 1. You should enable File VaultNOW, because it is the only protection against anyone with physical access to yourcomputer. All other security measures will be completely bypassed if someone withphysical access simply restarts the computer with a bootable pen drive.
File Vault really is secure, which means that you can permanently lose access to yourdata if you lose the passwords and the recovery key.
Set a Firmware PasswordSet a password to stop access to theRecovery mode. Otherwise, any maliciousindividual can change the firmware settings to boot from a disc or device of theirchoosing. If you did not enable File Vault, then the attacker will have complete accessto all of the files on the system.

Setting Up Time Machine BackupsTime Machine is simple to set up. Just take a suitably large external hard drive, plug itin to your Mac, and agree when prompted. The drive setup process will reformat the harddrive. The only settings that may need to change are the exclusions.
Choose System Preferences > Time Machine, and click Options. Add to the exclusionslist any folders that contain ISO disk images, virtual machines, or database files (suchas Entourage). If the external hard drive is short of space, exclude the Systemfolder.

Setting Up for DevelopmentThe first step is to install a compiler. The easiest way to install one is with theXcode Command Line Tools package.
Once you have the compiler that is provided by Xcode, you can useHomebrew to install everything else that you need.
Getting XcodeApple now provide the Xcode suite as a free download from the App Store. To installXcode Command Line Tools, install Xcode from the App Store, then open a Terminal windowand enter the following command:
Setting Up HomebrewHomebrew provides a package management system for macOS, enabling youto quickly install and update the tools and libraries that you need. Follow theinstructions on the site.
You should also amend your PATH, so that the versions of tools that are installed withHomebrew take precedence over others. To do this, edit the file .zshrc inyour home directory to include this line:
You need to close all terminal windows for this change to take effect.
To check that Homebrew is installed correctly, run this command in a terminal window:
To update the index of available packages, run this command in a terminal window:
Once you have set up Homebrew, use the brew install command to add command-line software to your Mac, and brew cask install to add graphical software. For example, this command installs the Slack app:
Enabling Auto Completion of CommandsMany command-line tools provide automatic completion of commands. These include Git, curl and the AWS command-line tool. Homebrew installs the files for each command-line tool that provides completion, but it does not enable automatic completion in your shell.
To enable auto completion, edit the file .zshrc in your home directory to include this line:
Close all of the Terminal windows. Every new Terminal window will support autocompletion.
To use auto completion, type the name of the command, and press the Tab key on your keyboard. You will see a list of possible completions. Press the Tab key to cycle through the completions, and press the Enter key to accept a completion.
Installing the Git Version Control SystemSet Up A Simple Web App On Mac Windows 10The Xcode Command Line Tools include a copy of Git, which isnow the standard for Open Source development, but this will be out of date.
To install a newer version of Git than Apple provide, use Homebrew. Enter this command in a terminal window:
If you do not use Homebrew, go to the Web site and follow thelink for Other Download Options to obtain a macOS disk image. Open your downloadedcopy of the disk image and run the enclosed installer in the usual way, then dismountthe disk image.
Always set your details before you create or clone repositories on a new system. Thisrequires two commands in a terminal window:

The global option means that the setting will apply to every repository that you workwith in the current user account.

Second, go to Safari > Preferences > Search. Decide which search engine that you want to use. Ensure that Safari Suggestions is not enabled.
Then, check the plug-in settings. Go to Safari > Preferences > Security > Plug-in Settings… and review the plug-ins and settings.

Text EditorsInstallations of macOS include older command-line versions of bothEmacs and vim, as well asTextEdit, a desktop text editor. TextEdit is designed for light-weight word processing,and has no support for programming. Add the code editors or IDEs that you would prefer to use.
If you do not have a preferred editor, consider using a version of Visual Studio Code. Read the next section for more details.
To work with a modern Vim editor, install Neovim.
Visual Studio CodeVisual Studio Code is a powerful desktop editor for programming, with built-in support for version control and debugging. The large range of extensions for Visual Studio Code enable it to work with every popular programming language and framework. It is available free of charge.
The Microsoft releases of Visual Studio Code are proprietary software with telemetry enabled by default. To avoid these issues, use the packages that are provided by the vscodium project instead.
Once you have installed Visual Studio Code or VSCodium, read this article for more information about using the editor.
NeovimIf you would like a modern Vim editor with a good default configuration, set up Neovim.
Setting The EDITOR Environment VariableWhichever text editor you choose, remember to set the EDITOR environment variable inyour ~/.zshrc file, so that this editor is automatically invoked by command-linetools like your version control system. For example, put this line in your profile tomake Neovim (nvim) the favored text editor:
Setting Up A Directory Structure for ProjectsTo keep your projects tidy, I would recommend following theGo developer conventions. These guidelines may seemslightly fussy, but they pay off when you have many projects, some of which are ondifferent version control hosts.
First create a top-level directory with a short, generic name like code. By default Gouses a directory called go, but you can change that when you set up a Go installation.
In this directory, create an src sub-directory. For each repository host, create asubdirectory in src that matches your username. Check out projects in the directory.The final directory structure looks like this:
Creating SSH KeysYou will frequently use SSH to access Git repositories or remote UNIX systems. macOSincludes the standard OpenSSH suite of tools.
OpenSSH stores your SSH keys in a .ssh directory. To create this directory, run these commands in a terminal window:
To create an SSH key, run the ssh-keygen command in a terminal window. For example:
Use 4096-bit RSA keys for all systems. The older DSA standard only supports 1024-bitkeys, which are now too small to be considered secure.
Programming LanguagesJavaScript Development: Node.jsHomebrew provides separate packages for each version of Node.js.To ensure that you are using the version of Node.js that you expect, specify the versionwhen you install it. For example, enter this command in a Terminal window to install theNode.js 12, the current LTS release:
Add the bin/ directory for this Node.js installation to your PATH:
If you need yarn, enter this command in a Terminal window toinstall it:
Go DevelopmentUse Homebrew to install Go:
This provides the standard command-line tools for Go.
The current version of Go includes support for dependency management with modules. Use modules for new projects. Some existing projects still use dep, or an older tool.
Setting a GOPATHCurrent versions of Go do not require a GOPATH environment variable, but you should set it to ensure that third-party tools and Terminal auto-completion work correctly.
Set a GOPATH environment variable in your ~/.zshrc file:
Then, add this to your PATH:
Close the Terminal and open it again for the changes to take effect.
Java Development: AdoptOpenJDKWhich Version of Java?Many vendors provide a JDK. To avoid potential licensing and support issues, use the JDK that is provided by the AdoptOpenJDK project. The versions of Java on the OpenJDK Website are for testers, and the Oracle JDK is a proprietary product that requires license fees.

Download Minecraft mods, tools and utilities that extend and modify the original Minecraft game. Anything is possible. Support the mod creators by providing feedback, subscribing and using their game mod.
Use the LTS version of the OpenJDK, unless you need features that are in the latest releases.
Once you have installed a JDK, get the Apache Maven build tool. This is provided by the Maven project itself, and is not part of the OpenJDK.
Use jEnv if you need to run multiple JDKs, such as different versions of the same JDK.
Setting up Java with HomebrewRun these commands in a terminal window:
This installs version 11 of the OpenJDK, from the AdoptOpenJDK project.
Run this command in a terminal window to install Maven:
Setting up jEnvRun this command in a terminal window to install jEnv:
Next, add this to your PATH:
Add this to your ~/.zshrc file:
Open a new terminal window, and run this command:
This enables jEnv to manage the JAVA_HOME environment variable.
To avoid inconsistent behaviour, close all the terminal windows that you currently have open. The jEnv utility will work correctly in new terminal windows.
Lastly, run this command to register your current JDK with jEnv:
To see a list of the available commands, type jenv in a terminal window:
Manual Set up of AdoptOpenJDKTo manually install a copy of the JDK:
Download the version of the JDK that you need from AdoptOpenJDK
Unzip the download
Copy the JDK directory to /usr/local/lib
Edit your ~/.zshrc file to set environment variables. For example, to use jdk-11.0.3+7 as the Java version:
To manually install a copy of Apache Maven:
Download the latest version of Maven
Unzip the download
Copy the Maven directory to /usr/local/lib/
Add /usr/local/lib/MAVEN-DIRECTORY to your PATH environment variable
Replace MAVEN-DIRECTORY with the name of the directory that Maven uses, such as apache-maven-3.6.0.
Maven is written in Java, which means that the project provides one package, which works on any operating system that has a supported version of Java.
Python Development: pipenvCurrent versions of macOS include a copy of Python 3, but this will not be the latest version of Python. Use Homebrew to install the latest release of Python.
To maintain current and clean Python environments, you should also use pipenv. This builds on two features of Python: the virtual environments and the pip utility.
Enter this command to install Python 3 and pipenv using Homebrew:
Use pipenv to manage your Python projects. The pipenv tool itself will automatically work with the copy of Python 3 from Homebrew.
To use the Python 3 interpreter outside of projects that are managed by pipenv, specify python3 on the command-line and inyour scripts, rather than python:
If you need to run the pip utility, rather than setting up a development environment with pipenv, always use the command pip3:
The Python Guide tutorialshows you how to work with pipenv.
Rust Development: rustupThe official rustup utility enables you to install the tools for building softwarewith the Rust programming language. Click on the Install button on the front page of theRust Website, and follow the instructions.
By default, the installer adds the correct directory to your path. If this does notwork, add this to your PATH manually:
This process installs all of the tools into your home directory, and does not add anyfiles into system directories.
Ruby Development: RVMAll macOS systems include a copy of Ruby, but it is outdated. To maintain current andclean Ruby environments, use the RVM system.
RVM relies on Git, so you must have a working installation of Git before you can set upRVM.
By default, RVM downloads copies of Ruby that have been compiled for your operatingsystem. If there is no compiled version, RVM then falls back to downloading the sourcecode and then compiling it on your computer. Enter this command to ensure that therequirements for compiling Ruby are on your system, using Homebrew:
Finally, you can speed up installation of gem packages by disabling the generation oflocal documentation. To do this, create a file in your home directory with the name.gemrc and put this line in it:
Kubernetes: MinikubeMinikube sets up and manages Kubernetes on a single system, so that you can develop and test without needing a set of servers.
To install Minikube with Homebrew, run these commands in a terminal window:
By default, Minikube uses a virtual machine manager. If you do not need VirtualBox, install hyperkit, which provides a minimal virtual machine manager.
To install Helm with Homebrew, run this command in a terminal window:
To install Skaffold with Homebrew, run this command in a terminal window:
This article explains Minikube in more detail.
Set Up A Simple Web App On Mac ShortcutSQL DatabasesConsider using containers to run the databases that you need. If you prefer to install servicesdirectly on to your workstation, Homebrew provides packages for PostgreSQL, MariaDB and MySQL.
Installing PostgreSQLTo install PostgreSQL using Homebrew, enter this command in a terminal window:
This command installs the server, the command-line tools, and the client libraries thatare needed to compile adapters for programming languages.
Homebrew also provides some commands for managing your PostgreSQL installation. Forexample, to start the server, follow the instructions that are displayed after theinstallation process is completed. If you upgrade your copy of PostgreSQL, you shoulduse the postgresql-upgrade-database command that Homebrew gives you.
Installing MariaDB or MySQLTo install MariaDB using Homebrew, enter this command in a terminal window:
To install MySQL using Homebrew, enter this command in a terminal window:
These commands install the server, the command-line tools, and the client libraries thatare needed to compile adapters for programming languages. To start the server, followthe instructions that are displayed after the installation process is completed.
For compatibility, MariaDB uses the same names for command-line tools as MySQL.
Remember to set a password for the root accounts. First, login with the mysqlcommand-line utility:
The -q Option Disables Command History: By default, the command-line client storesthe full text of every command in a history file. If you know that you are going torun statements that include passwords or other sensitive data, use the -q option.
Run these statements to change the password for root access:
You now need a password to login to the installation as root. To login with root again,use this command:
Enter the password when prompted.
You should also remove the anonymous accounts and test database that MySQL automaticallyincludes:
If you intend to duplicate a production environment for testing, create a configurationfile on your Mac. Production installations of MySQL should be configured withappropriate SQL modes to enable data integrity safeguards. By default, MySQL permitsvarious types of invalid data to be entered.

This article explains how to set up a simple local testing server on your machine, and the basics of how to use it.
Prerequisites:You need to first know how the Internet works, and what a Web server is.
Objective:You will learn how to set up a local testing server.
Local files vs. remote filesThroughout most of the learning area, we tell you to just open your examples directly in a browser — this can be done by double clicking the HTML file, dragging and dropping it into the browser window, or choosing File > Open.. and navigating to the HTML file. There are many ways to achieve this.
If the web address path starts with file:// followed by the path to the file on your local hard drive, a local file is being used. In contrast, if you view one of our examples hosted on GitHub (or an example on some other remote server), the web address will start with http:// or https://, to show that the file has been received via HTTP.
The problem with testing local filesSome examples won't run if you open them as local files. This can be due to a variety of reasons, the most likely being:
They feature asynchronous requests. Some browsers (including Chrome) will not run async requests (see Fetching data from the server) if you just run the example from a local file. This is because of security restrictions (for more on web security, read Website security).
They feature a server-side language. Server-side languages (such as PHP or Python) require a special server to interpret the code and deliver the results.
Running a simple local HTTP serverTo get around the problem of async requests, we need to test such examples by running them through a local web server. One of the easiest ways to do this for our purposes is to use Python's SimpleHTTPServer (or http.server, depending on the version of Python installed.)
To do this:
Install Python. If you are using Linux or macOS, it should be available on your system already. If you are a Windows user, you can get an installer from the Python homepage and follow the instructions to install it:
Go to python.org
Under the Download section, click the link for Python '3.xxx'.
At the bottom of the page, choose the Windows x86 executable installer and download it.
When it has downloaded, run it.
On the first installer page, make sure you check the 'Add Python 3.xxx to PATH' checkbox.
Click Install, then click Close when the installation has finished.
Open your command prompt (Windows)/ terminal (macOS/ Linux). To check Python is installed, enter the following command:
This should return a version number. If this is OK, navigate to the directory that your example is inside, using the cd command.
Enter the command to start up the server in that directory:
By default, this will run the contents of the directory on a local web server, on port 8000. You can go to this server by going to the URL localhost:8000 in your web browser. Here you'll see the contents of the directory listed — click the HTML file you want to run.
Note: If you already have something running on port 8000, you can choose another port by running the server command followed by an alternative port number, e.g. python3 -m http.server 7800 (Python 3.x) or python -m SimpleHTTPServer 7800 (Python 2.x). You can then access your content at localhost:7800.
Running server-side languages locallyPython's SimpleHTTPServer (python 2.0) http.server (python 3.0) module is useful, but it doesn't know how to run code written in languages such as Python, PHP or JavaScript. To handle that you'll need something more — exactly what you'll need depends on the server-side language you are trying to run. Here are a few examples:
Set Up A Simple Web App On MacbookTo run Python server-side code, you'll need to use a Python web framework. You can find out how to use the Django framework by reading Django Web Framework (Python). Flask is also a good (slightly less heavyweight) alternative to Django. To run this you'll need to install Python/PIP, then install Flask using pip3 install flask. At this point you should be able to run the Python Flask examples using for example python3 python-example.py, then navigating to localhost:5000 in your browser.
To run Node.js (JavaScript) server-side code, you'll need to use raw node or a framework built on top of it. Express is a good choice — see Express Web Framework (Node.js/JavaScript).
To run PHP server-side code, launch PHP's built-in development server:
