- Session Persistence: You can store data such as the user's login information so that the application automatically recognizes the user in the next session.
- Conditional Storage: If the user has checked a checkbox (checkbox.value == true), save the data.
- Storage with JSON: You can save an object belonging to the user in JSON format and convert it back to an object later. For example, Value: JSON.stringify (name: user.name, lang: “tr” )
Technical Risks and Controls
- Data Bloat: Excessive data writing can cause performance issues in the browser.
- Browser Storage Limits: Typically limited to 5-10MB per domain.
- Format Errors: If JSON data is formatted incorrectly, JSON.parse() errors may occur during reading.
- Security: Local Storage is an open environment; sensitive data (passwords, tokens) should never be stored in plain text.
- Key Collision: If data is written to the same key multiple times, the previous data will be overwritten. Ensure that keys are uniquely identified.
The Write To Local Storage action is a powerful tool for making the user experience persistent, preserving session-independent preferences, and increasing the dynamism of your application. It can be easily integrated with scenarios in web and mobile environments and, when used in conjunction with actions such as Read and Delete, provides an effective data management infrastructure.
