Web support for API Dash

[ShashwatXD]

Tell us about the task you want to perform and are unable to do so because the feature is not available

Currently, API Dash cannot be accessed or explored from the web. This makes it harder for new users to quickly try the tool, understand the workflow, or build sample requests without installing the desktop or mobile app upfront.
Additionally, API testing from a browser is constrained by CORS, which prevents certain requests from being executed reliably in a pure web environment.

Describe the solution/feature you'd like us to add

Findings:

1. Proxy-based web support:

A managed proxy or a user-hosted proxy can enable full request execution from the web, offering functionality closer to desktop parity. This approach provides maximum capability but introduces additional considerations around infrastructure, configuration, and maintenance.

2. Web-to-desktop handoff approach

The web client focuses on request creation and organization. When a request cannot be executed due to CORS:

• The failure is detected in the web client
• Users are offered a fallback to the desktop app via deeplinks or firstly download the app.

Any other feedback you would like to provide regarding the site

Looking for guidance on the preferred direction.

Past discussion on this issue:

My understanding on this:
API Dash Web will not host or maintain any proxy. Users who want to run requests on the web will need to self-host a proxy and configure it in the web app settings. API Dash will only provide the configuration option, basic handling when direct requests fail, and documentation/templates to help users set up their own proxy. The proxy itself remains fully user-managed.

If i am on the right way ,lmk @animator so i can research more on this path.

Yes your understanding is right.

@animator Check this out,

• created a web support of API dash with cors setup as discussed.
• Used stubs to avoid conflict of flutter_js on web, have amde sure my changes dont affect other platforms.
• Have used cors-anywhere node.js package to create a proxy server.

Hey @animator, as discussed I have split the changes into multiple PRs, each focusing on a specific topic.
