Testing AWS AppSync GraphQL APIs with AWS Amplify - Authorization and Custom Queries

Nader Dabit: [00:00] We'll start by creating a new 
[00:00] Amplify project by running 
[00:02] amplify init. Next, we'll add 
[00:27] authentication by running 
[00:29] amplify add auth. Here, we'll 
[00:31] choose the default configuration 
[00:32] allowing users to sign in with 
[00:33] their username. We're adding 
[00:35] authentication, so we can test 
[00:36] authorization rules against our 
[00:39] GraphQL API. We'll create the 
[00:41] GraphQL API by running amplify 
[00:43] add API.
[00:49] When prompted for a 
[00:50] guided schema creation, we'll 
[00:52] choose yes, and then single 
[00:53] object with fields as the 
[00:55] starter project. This will start 
[00:59] us off with a basic to-do 
[01:01] application with an ID, name and 
[01:03] description field within the to-
[01:05] do type.
[01:09] To test the API, we 
[01:11] can run amplify mock API. The 
[01:13] CLI will run GraphQL code 
[01:15] generation, so you could also 
[01:16] test the API out from your 
[01:18] client application. Once the 
[01:20] endpoint is up-and-running, we 
[01:21] can now test it out.
[01:25] We'll 
[01:26] first create a couple of to-dos 
[01:27] by running the create to-do 
[01:28] mutation. Next, we'll fetch a 
[01:46] list of to-dos by running the 
[01:48] list to-dos query. We can also 
[01:58] get a single to-do by ID, by 
[02:00] running get to-do. For our next 
[02:13] API, I'll open the GraphQL 
[02:14] recipes blog post and look for 
[02:16] the events app.
[02:35] We'll save the 
[02:36] schema, and then run amplify 
[02:38] mock API. To test this out, 
[02:43] we'll create a couple of events 
[02:44] by running the createEvent 
[02:46] mutation. To query for the event, 
[03:15] we'll run the listEvents query. 
[03:23] Here, we'll notice that the 
[03:24] events come back, but they're 
[03:25] not in any particular order. To 
[03:31] get the events by date, we can 
[03:32] run the eventsByDate query.
[03:49] The 
[03:49] next schema that we'll test out 
[03:51] is for a conference app. We'll 
[04:20] save the schema, and then run 
[04:22] amplify mock API. Next, we'll 
[04:28] test this out by trying to 
[04:30] create a new talk. We'll notice 
[04:46] that we get an unauthorized 
[04:48] exception because only an admin 
[04:50] can create a talk. To simulate 
[04:54] an admin, we'll open the auth 
[04:55] options, and add us to the admin 
[04:57] group.
[05:03] Now, the mutation is 
[05:04] successful. To query for all of 
[05:12] the talks, we can run the 
[05:14] listTalks query. This query 
[05:23] returns a list of talks as 
[05:25] expected.
