Node.js Store In Mac Library

Your Photos library holds all your photos, albums, slideshows, and print projects. If your library is large, and you want to free up storage space on your Mac, turn on iCloud Photo Library and use Optimize Mac Storage, or move your library to an external drive.

Last updated Saturday, Nov 16, 2019 Setting up Node.js and npm on Mac OSX Node.js is gaining a lot of speed and is an exciting new development framework. Here's a quick overview of how to get Node.js working on OSX along with npm, the package manager for node. With Node.js apps, environment variables are available through the process.env global variable. We can set the environment variables before we run the node command, or we can use the dotenv library which allows us to define our environment variables in a.env file. The.env file should never be in the source code repository.

Before you start, be sure to back up your library.

Prepare your drive

You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled).¹ Find out how to check the format of your external storage device.

To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.

Move your Photos library to an external storage device

1. Quit Photos.
2. In the Finder, go to the external drive where you want to store your library.
3. In another Finder window, find your library. The default location is Users > [username] > Pictures, and it's named Photos Library.
4. Drag your library to its new location on the external drive. If you see an error, select your external drive's icon in the Finder, then choose File > Get Info. If the information under Sharing & Permissions isn't visible, click , then make sure the 'Ignore ownership on this volume' checkbox is selected. If it's not selected, click to unlock it, enter an administrator name and password, then select the checkbox.²
   
   
5. After the move is finished, double-click Photos Library in its new location to open it.
6. If you use iCloud Photo Library, designate this library as the System Photo Library.

Delete original library to save space

After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.

In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.

Open another Photos library

If you have multiple libraries, here's how to open a different one:

1. Quit Photos.
2. Press and hold the Option key while you open Photos.
3. Select the library that you want to open, then click Choose Library.

Photos uses this library until you open a different one.

If you have a permissions issue with your library, you might be able to resolve the issue by using the Photos library repair tool.

1. You can't move your library to a disk that's used for Time Machine backups.

2. If the volume isn't formatted APFS or Mac OS Extended (Journaled), or has been used for Time Machine backups but hasn't been erased, this checkbox will either not be present, or won't be selectable after unlocking. Erase and reformat the drive for this option to be available.

In this section you will create three simple Node.js apps. One of them will just connect to the database, the second will perform basic Insert, Update, Delete, and Select, and the third one will make use of Sequelize, one of the most popular Node.js Object-relational mappers, to execute the same operations.

Step 2.1 Create a Node.js app that connects to SQL Server and executes queries

Create a new project directory and initialize Node dependencies.

Create a database that will be used for the rest of this tutorial by connecting to SQL Server using sqlcmd and executing the following statement.

Now you will create a simple Node.js app that connects to SQL Server.

Using your favorite editor, create a file named connect.js in the SqlServerSample folder. Copy and paste the below contents into the file.

Run the application.

Using your favorite text editor, create a file called CreateTestData.sql in the SqlServerSample folder. Copy and paste the following the T-SQL code inside it. This will create a schema, table, and insert a few rows.

Unable to load authentication library exiting mac. Connect to the database using sqlcmd and run the SQL script to create the schema, table, and insert some rows.

Using your favorite text editor, create a new file called crud.js in the SqlServerSample folder. Copy and paste the following code inside it. This will insert, update, delete, and read a few rows.

Run the crud.js app to see the results

Step 2.2 Create a Node.js app that connects to SQL Server using the popular Sequelize ORM

Create the app directory and initialize Node dependencies.

1. Open your favourite text editor and create the file orm.js in the directory SqlServerSequelizeSample.
2. Paste the contents below into orm.js
3. Update the variable for password to use your own password specified in the first module.
4. Save and close orm.js

Run the orm.js app
