Angular Local Storage is a built-in module in AngularJS. This module aligns perfectly with the AngularJS way of doing things and provides two unique, specialized services: $localStorage and $sessionStorage. These services have been constructed to make Web Storage operations compatible and convenient with AngularJS.

Comparing Angular Local Storage with Other Implementations
Angular local storage stands out due to several unique features. Here’s how it differs from other implementations:
- No need for getter and setter functions: Thanks to the built-in functionality of AngularJS, data manipulation does not require any wrapping or accessor methods. The workflow remains smooth with plain JavaScript;
- sessionStorage coverage: The module seamlessly integrates the sessionStorage functionality, which is often ignored in other frameworks;
- Easy-to-read code: The code is formulated following the AngularJS guidelines, ensuring clean, structured, and easily testable code;
- No fallback to cookies: AngularJS backs Web Storage by default making a fallback mechanism to cookies obsolete.
Setting Up Angular Local Storage
This segment will guide you on how to install Angular local storage, utilize its services, and its basic operations.
Reading and Writing Data with Angular Local Storage
- The $localStorage and $sessionStorage services can be easily referenced to a hook under $scope;
- The data can be read and written in an uncomplicated JavaScript manner;
- Any changes to the data will be automatically synchronized across multiple browser tabs.
Alternative Methods for Reading and Writing Data
For developers less inclined towards utilizing $scope.$storage, the method of using watchers is also an option. However, this alternative method is verbose and could potentially affect performance negatively due to the growth of watched values.
Removing Data from Angular Local Storage
Data deletion within the Web Storage follows the same straightforward JavaScript procedure. The desired entry can be easily removed from the Web Storage.
Deleting All Data from Angular Local Storage
- If there’s a need to mass-erase all data from the storage, $reset() method is an efficient solution;
- It can also be used to reset the storage to a new default data set.
Acceptable Data Types
The system accepts a wide range of data types, with the exception of a few that are incompatible with JSON formatting. Specifically:
- Infinity and NaN: These values will be substituted with null;
- undefined and Function: These entries will not be retained in the data.
Minification Process
To prepare your web assets for efficient loading, start by setting up the necessary tools.
- Begin by executing $ npm install in your terminal to download all required dependencies;
- Once the setup is complete, initiate the compression process by running $ grunt.
This step reduces the size of your files, ensuring faster web performance and improved user experience.
Conclusion
Angular Local Storage offers a streamlined, efficient, and Angular-friendly way to handle Web Storage. Its services, $localStorage and $sessionStorage, provide a smooth workflow for data persistence. With Angular Local Storage, you can manage data easily, test your code effectively, and optimize your Angular applications with seamless data persistence across browser tabs.
Angular’s local storage is a powerful tool that allows developers to efficiently manage data storage within their applications. Its inherent services, $localStorage and $sessionStorage, simplify data reading and writing tasks significantly. Additionally, Angular local storage trumps other implementations with its Angular-friendly approach, extensive sessionStorage coverage, and clean, testable code. Whether you’re storing simple data or implementing complex data manipulation tasks, Angular local storage is a resource-efficient and reliable solution to consider.
