responseJsonMethods

Prefer Response.json() over new Response(JSON.stringify(...)) for JSON responses.

✅ This rule is included in the ts stylistic presets.

The Response.json() static method provides a cleaner way to create JSON responses compared to manually calling new Response(JSON.stringify(data)). Using Response.json() is more concise and automatically sets the Content-Type header to application/json.

This rule flags cases where new Response(JSON.stringify(data)) can be replaced with Response.json(data).

Options

This rule is not configurable.

When Not To Use It

If you need to pass additional options to JSON.stringify() like a replacer or space parameter, you’ll need to use the manual approach. Similarly, if you need to set custom response options like status or additional headers beyond Content-Type, use new Response() directly.
