Definition of terms for CRUD App
- Create – Sending HTTP POST queries to the API creates resources. The kind of resource is decided by the URL of the request. A JSON object describing the resource to create should be included in the body of the request.
- Read – Resources are retrieved by performing HTTP GET queries. There are two major approaches to retrieve resources. Requesting a list of resources is the first method, while requesting a single resource is the second method.
- Update – HTTP PATCH requests to the URL where the resource is located are used to make updates. When a PATCH request is made, the request body’s properties are read, and if the resource has a property with the same name, the resource’s property is updated to the new value.
- Delete – By making an HTTP DELETE request to the resource’s URL, the resource can be erased. This is the resource’s id in the form of a URL.
