reactjs - PHP backend sometimes return status code 500 with HTML, how can my react front end handle this?

Solution:

Response, even an error response, should containContent-Type header which in your case should be eitherapplication/json for JSON responses andtext/html for HTML responses. You should always only JSON-decode responses withapplication/json content type. Actually axios will do that for you if a proper content type header is present on the response.

There's a chance though that your API is returning JSON withtext/html content type. If that happens, you have to have some serious discussion with your backend developers and strongly insist on having properContent-Type on all API responses.

An app called Facebook Ads grew very quickly, which meant complex management and support. As a result, the team began to create a structure that would help them with efficiency. They had an early prototype before 2011, and two years later, the framework was open source and available to the public. It is currently used by many business giants: AirBNB, PayPal, Netflix, etc.
