Introduction to a practical tool for quickly opening localstorage files
Foreword:
In front-end development, we often need to use local storage to save user data. One of the widely used local storage solutions is localstorage. Localstorage provides a simple key-value pair storage method, and has a large storage space and a simple and easy-to-use API. However, when we need to view and modify the data in localstorage, we often need some additional tools to help us. This article will introduce some practical tools for quickly opening localstorage files, providing developers with a convenient way to manage local storage data.
1. Location of localstorage files
In most modern browsers, localstorage data is stored in the user's local hard drive. The exact location varies based on different operating systems and browsers. Here are some common localstorage file storage locations:
-
Chrome browser:
- Windows: C:UsersAppDataLocalGoogleChromeUser DataDefaultLocal Storage
- macOS:/Users//Library/Application Support/Google/Chrome/Default/Local Storage
- Linux:~/.config/google-chrome/Default/Local Storage
- ##Firefox browser:
Windows: C:UsersAppDataRoamingMozillaFirefoxProfilesstorage.sqlite-
macOS:/Users//Library/Application Support/Firefox/Profiles//storage.sqlite- Linux:~/.mozilla/firefox/< ;profile-name>/storage.sqlite
- Safari browser:
Windows:C:UsersAppDataRoamingApple ComputerSafariLocalStorage- macOS:/Users//Library/Safari/LocalStorage
##2. Introduction to practical tools
Chrome DevTools
The developer tools that come with the Chrome browser-DevTools is a powerful debugging tool that includes support for localstorage. Open the Chrome browser, press the F12 key or right-click on the web page and select "Inspect" or "Element Inspection" to open DevTools. Under the "Application" or "Application" tab of DevTools, we can find relevant information about localstorage. You can view and modify localstorage key-value pairs, and even export and import localstorage backup files. -
Firefox Storage Inspector The Storage Inspector that comes with the Firefox browser is a tool specifically used to view and modify local storage data. Open the Firefox browser, press the F12 key or right-click on the web page, select "Inspect Element" or "Inspect Element" to open the developer tools. In the right panel of the developer tools, select the "Storage" or "Storage" tab to find localstorage related information. Here you can view and modify the key-value pairs of localstorage. -
Third Party Tools In addition to the tools that come with the browser, there are also some third-party tools that can help us manage localstorage more conveniently. One commonly used tool is localForage. localForage is a simple and powerful JavaScript library that provides a unified API to access various local storage solutions, including localstorage, IndexedDB and WebSQL. Through localForage, we can read, write and query data in localstorage more flexibly.
Code example:
Open the localstorage file using Chrome DevTools: -
Open the Chrome browser and press the F12 key or Right-click on the web page and select "Inspect" or "Element Inspection"
- Under the "Application" tab of DevTools, select "Local Storage" and expand
- You can view and modify the keys of localstorage Value pair
-
Use Firefox Storage Inspector to open the localstorage file: -
Open the Firefox browser, press the F12 key or right-click the web page and select " Inspect Element" or "Inspect Element"
- In the right panel of the developer tools, select the "Storage" tab
- Under "Local Storage", you can view and modify localstorage Key-value pairs
-
#Use localForage to read and write localstorage data:
- Introduce the localForage library into HTML:
- Initialize localForage: const storage = localforage.createInstance({name: "myStorage"});
- Store data to localstorage: storage.setItem("key", "value") ;
- Read data: storage.getItem("key").then(function(value) {console.log(value);});
- Delete data: storage.removeItem( "key");
Conclusion:
The above introduces some practical tools for quickly opening localstorage files, as well as sample code for using the localForage library to read and write localstorage data. These tools and libraries can help developers manage and operate data in localstorage more conveniently and improve development efficiency. I hope this article will be helpful to developers who learn and use localstorage.
