What are the Limitations and Considerations When Using Opaque Responses in the Fetch API?

Limitations of Opaque Responses in the Fetch API

Opaque responses, defined in the Fetch API, stem from cross-origin requests made without CORS (Cross-Origin Resource Sharing) enabled, imposing certain limitations on their usage.

Access Restrictions:

Firstly,opaque responses cannot reveal meaningful details via Response properties such as headers or Body methods due to their black-box nature.

Use as Page Resources:

Opaque responses serve as valid resources for specific elements on a web page where non-CORS cross-origin resources are permissible. According to Mozilla Developer Network documentation, compatible elements include:

• • An in-depth analysis of the Bootstrap list group component
  • Detailed explanation of JavaScript function currying
  • Complete example of JS password generation and strength detection (with demo source code download)
  • Angularjs integrates WeChat UI (weui)
  • How to quickly switch between Traditional Chinese and Simplified Chinese with JavaScript and the trick for websites to support switching between Simplified and Traditional Chinese_javascript skills
