Full Transcript

even with HTTP there are multiple API patterns we could follow the most popular one being rest which is a standardization around HTTP apis making them stateless and following consistent guidelines like a successful request should include a 200 code in its response header whereas a bad request from the client would return a 400 code and an issue with the server would result in a 500 level code graphql is another API pattern introduced by Facebook in 2015 the idea is that instead of making another request for every single resource on your server like you would do with rest with graphql you can just make a single request AKA a query and you can choose exactly which resources you want to fetch this means you can fetch multiple resources with a single request and you also don't end up over fetching any data that's not actually needed
