### Platform-specific instructions

46-
#### A. When using Bref
47-
48-
Next, when using Bref, we have to add some elements to our `serverless.yml` file. If using Vapor, these resources have
49-
to be created by hand using the AWS CLI or console.
50-
51-
Add a new function that will handle websocket events (messages etc):
52-
53-
```yaml
54-
functions:
55-
# Add this function
56-
websocket:
57-
handler: handlers/websocket.php
58-
layers:
59-
- ${bref:layer.php-80}
60-
events:
61-
- websocket: $disconnect
62-
- websocket: $default
63-
```
64-
65-
Add a resource to create and configure our DynamoDB table, where connections will be stored in:
66-
67-
```yaml
68-
resources:
69-
Resources:
70-
# Add this resource
71-
ConnectionsTable:
72-
Type: AWS::DynamoDB::Table
73-
Properties:
74-
TableName: connections
75-
AttributeDefinitions:
76-
- AttributeName: connectionId
77-
AttributeType: S
78-
- AttributeName: channel
79-
AttributeType: S
80-
KeySchema:
81-
- AttributeName: connectionId
82-
KeyType: HASH
83-
- AttributeName: channel
84-
KeyType: RANGE
85-
GlobalSecondaryIndexes:
86-
- IndexName: lookup-by-channel
87-
KeySchema:
88-
- AttributeName: channel
89-
KeyType: HASH
90-
Projection:
91-
ProjectionType: ALL
92-

93-
KeySchema:
94-

95-
KeyType: HASH
96-
Projection:
97-
ProjectionType: ALL
98-
BillingMode: PAY_PER_REQUEST
99-
```
100-
101-
Add the following `iamRoleStatement` to enable our Lambda function to access the table:
102-
103-
```yaml
104-
provider:
105-
name: aws
106-
107-
iamRoleStatements:
108-
# Add this iamRoleStatement
109-
- Effect: Allow
110-
Action: [ dynamodb:Query, dynamodb:GetItem, dynamodb:PutItem, dynamodb:UpdateItem, dynamodb:DeleteItem, dynamodb:BatchWriteItem ]
111-
Resource:
112-
- !GetAtt ConnectionsTable.Arn
113-
- !Join [ '', [ !GetAtt ConnectionsTable.Arn, '/index/*' ] ]
114-
```
115-
116-
Add an environment variable to autogenerate our websocket URL:
117-
118-
```yaml
119-
provider:
120-
name: aws
121-
122-
environment:
123-
# Add these variables
124-
BROADCAST_DRIVER: laravel-echo-api-gateway
125-
LARAVEL_ECHO_API_GATEWAY_DYNAMODB_TABLE: !Ref ConnectionsTable
126-
LARAVEL_ECHO_API_GATEWAY_API_ID: !Ref WebsocketsApi
127-
LARAVEL_ECHO_API_GATEWAY_API_STAGE: "${self:provider.stage}"
128-
```
129-
130-
Next, create the PHP handler file in `handlers/websocket.php`
131-
132-
```php
133-
<?php
134-
135-
use Georgeboot\LaravelEchoApiGateway\Handler;
136-
use Illuminate\Foundation\Application;
137-
138-
require __DIR__ . '/../vendor/autoload.php';
139-
140-
/** @var Application $app */
141-
$app = require __DIR__ . '/../bootstrap/app.php';
142-
143-
$kernel = $app->make(Illuminate\Contracts\Console\Kernel::class);
144-
$kernel->bootstrap();
145-
146-
return $app->make(Handler::class);
147-
```
148-
149-
Now, deploy your app by running `serverless deploy` or similar. Write down the websocket url the output gives you.
150-
151-
#### B. When using Vapor
152-
153-
When using Vapor, you will have to create these required resources by hand using the AWS CLI or Console:
154-
155-
##### B1. DynamoDB table for connections
156-
157-
Create a DynamoDB table for the connections. Use `connectionId` (string) as a HASH key, and `channel` (string) as a SORT
158-
key. Set the capacity setting to whatever you like (probably on-demand).
159-
160-
Create 2 indexes:
161-
162-
1. Name: `lookup-by-connection`, key: `connectionId`, no sort key, projected: ALL
163-
2. Name: `lookup-by-channel`, key: `channel`, no sort key, projected: ALL
164-
165-
##### B2. API Gateway
166-
167-
Create a new Websocket API. Enter a name and leave the route selection expression to what it is. Add a `$disconnect`
168-
and `$default`. Set both integrations to `Lambda` and select your CLI lambda from the list. Set the name of the stage to
169-
what you desire and create the API. Once created, write down the ID, as we'll need it later.
170-
171-
##### B3. IAM Permissions
172-
173-
In IAM, go to roles and open `laravel-vapor-role`. Open the inline policy and edit it. On the JSON tab,
174-
add `"execute-api:*"` to the list of actions.
175-
176-
Then, login to [Laravel Vapor](https://vapor.laravel.com/app), go to team settings, AWS Accounts, click on Role next to
177-
the correct account and deselect Receive Updates.
178-
179-
Edit your `.env`:
180-
181-
```dotenv
182-
BROADCAST_DRIVER=laravel-echo-api-gateway
183-
LARAVEL_ECHO_API_GATEWAY_DYNAMODB_TABLE=the-table-name-you-entered-when-creating-it
184-
LARAVEL_ECHO_API_GATEWAY_API_ID=your-websocket-api-id
185-
LARAVEL_ECHO_API_GATEWAY_API_STAGE=your-api-stage-name
186-

130+
LARAVEL_ECHO_API_GATEWAY_API_STAGE: "${self:provider.stage}"
131+
```
132+

147+
$kernel->bootstrap();
148+
149+
return $app->make(Handler::class);
150+
```
151+
152+
Now, deploy your app by running `serverless deploy` or similar. Write down the websocket url the output gives you.
