This request will use the least amount of bandwidth as it will return no data, simply just a 200 (resource exists) or 404 (resource does not exist) HTTP status. The commonly accepted way to determine if a resource exists, using the above “user” resource as an example, is like so: PUT /users/ (retrieve a user model)ĭetermining whether a resource exists is an action that is frequently required in APIs, but is rarely done correctly according to the RESTful and industry standards.Instead, a truly RESTful path should only contain nouns-the method used on the endpoint should determine the action. A common mistake when building endpoints is to use descriptive verbs in the path. The above questions should get you a pretty good idea on what you might be asked in a MERN stack, fullstack developer interview.The purpose of this question is to test the candidate’s knowledge of RESTful API standards.
