I currently don't have the time to maintain this package.
My recommendation is to use Soketi serverless instead: https://renoki-25232877.hubspotpagebuilder.eu/soketi-serverless
Basically free to use and very well build.
This package enables you to use API Gateway‘s Websockets as a driver for Laravel Echo , so you don’t have to use services like Pusher or Socket.io.
It works by setting up a websocket API in API Gateway, and configure it to invoke a Lambda function, every time a message is sent to the websocket. This package includes and autoconfigures a handler to respond to these websocket messages. We also configure Laravel to use this connection as a broadcast driver.
This package currently only works with either Bref or Laravel Vapor, though the latter one involves some manual set-up.
As soon as version 1.0 will be released, this package will be suitable for production workloads. Until then, it is advised to only use this package for non-critical / non-production projects.
In order to use this package, your project needs to meet the following criteria:
- PHP 7.4 or 8.x
- Laravel 6, 7 or 8
- Uses either bref or Laravel Vapor to deploy to AWS
- Has a working queue
- Uses Laravel Mix or any other tool to bundle your assets
Installation of this package is fairly simply.
First we have to install both the composer and npm package:
composer require georgeboot/laravel-echo-api-gateway
yarn add laravel-echo-api-gateway
# or
npm install --save-dev laravel-echo-api-gateway
Next, when using Bref, we have to add some elements to our serverless.yml
file. If using Vapor, these resources have
to be created by hand using the AWS CLI or console.
Add a new function that will handle websocket events (messages etc):
functions:
# Add this function
websocket:
handler: handlers/websocket.php
layers:
- ${bref:layer.php-80}
events:
- websocket: $disconnect
- websocket: $default
Add a resource to create and configure our DynamoDB table, where connections will be stored in:
resources:
Resources:
# Add this resource
ConnectionsTable:
Type: AWS::DynamoDB::Table
Properties:
TableName: connections
AttributeDefinitions:
- AttributeName: connectionId
AttributeType: S
- AttributeName: channel
AttributeType: S
KeySchema:
- AttributeName: connectionId
KeyType: HASH
- AttributeName: channel
KeyType: RANGE
GlobalSecondaryIndexes:
- IndexName: lookup-by-channel
KeySchema:
- AttributeName: channel
KeyType: HASH
Projection:
ProjectionType: ALL
- IndexName: lookup-by-connection
KeySchema:
- AttributeName: connectionId
KeyType: HASH
Projection:
ProjectionType: ALL
BillingMode: PAY_PER_REQUEST
Add the following iamRoleStatement
to enable our Lambda function to access the table:
provider:
name: aws
iamRoleStatements:
# Add this iamRoleStatement
- Effect: Allow
Action: [ dynamodb:Query, dynamodb:GetItem, dynamodb:PutItem, dynamodb:UpdateItem, dynamodb:DeleteItem, dynamodb:BatchWriteItem ]
Resource:
- !GetAtt ConnectionsTable.Arn
- !Join [ '', [ !GetAtt ConnectionsTable.Arn, '/index/*' ] ]
Add an environment variable to autogenerate our websocket URL:
provider:
name: aws
environment:
# Add these variables
BROADCAST_DRIVER: laravel-echo-api-gateway
LARAVEL_ECHO_API_GATEWAY_DYNAMODB_TABLE: !Ref ConnectionsTable
LARAVEL_ECHO_API_GATEWAY_API_ID: !Ref WebsocketsApi
LARAVEL_ECHO_API_GATEWAY_API_STAGE: "${self:provider.stage}"
Next, create the PHP handler file in handlers/websocket.php
<?php
use Georgeboot\LaravelEchoApiGateway\Handler;
use Illuminate\Foundation\Application;
require __DIR__ . '/../vendor/autoload.php';
/** @var Application $app */
$app = require __DIR__ . '/../bootstrap/app.php';
$kernel = $app->make(Illuminate\Contracts\Console\Kernel::class);
$kernel->bootstrap();
return $app->make(Handler::class);
Now, deploy your app by running serverless deploy
or similar. Write down the websocket url the output gives you.
When using Vapor, you will have to create these required resources by hand using the AWS CLI or Console:
Create a DynamoDB table for the connections. Use connectionId
(string) as a HASH key, and channel
(string) as a SORT
key. Set the capacity setting to whatever you like (probably on-demand).
Create 2 indexes:
- Name:
lookup-by-connection
, key:connectionId
, no sort key, projected: ALL - Name:
lookup-by-channel
, key:channel
, no sort key, projected: ALL
Create a new Websocket API. Enter a name and leave the route selection expression to what it is. Add a $disconnect
and $default
. Set both integrations to Lambda
and select your CLI lambda from the list. Set the name of the stage to
what you desire and create the API. Once created, write down the ID, as we'll need it later.
In IAM, go to roles and open laravel-vapor-role
. Open the inline policy and edit it. On the JSON tab,
add "execute-api:*"
to the list of actions.
Then, login to Laravel Vapor, go to team settings, AWS Accounts, click on Role next to the correct account and deselect Receive Updates.
Edit your .env
:
BROADCAST_DRIVER=laravel-echo-api-gateway
LARAVEL_ECHO_API_GATEWAY_DYNAMODB_TABLE=the-table-name-you-entered-when-creating-it
LARAVEL_ECHO_API_GATEWAY_API_ID=your-websocket-api-id
LARAVEL_ECHO_API_GATEWAY_API_STAGE=your-api-stage-name
Add to your javascript file:
import Echo from 'laravel-echo';
import {broadcaster} from 'laravel-echo-api-gateway';
window.Echo = new Echo({
broadcaster,
// replace the placeholders
host: 'wss://{api-ip}.execute-api.{region}.amazonaws.com/{stage}',
});
Lastly, you have to generate your assets by running Laravel Mix. After this step, you should be up and running.
