can't remove laravel_database_ prefix from channel - php

Question

I'm setting up Laravel echo to broadcast events. But whenever I try to broadcast to a channel the channel name gets an automatic prefix: 'laravel_database_'
I've tried switching the return inside the Event to a regular 'Chanel' as following:
public function broadcastOn()
{
return new Channel('public');
}
but when I look into the laravel-echo-server logs I see it is still being broadcasted on: 'laravel_database_public'.
This way I would need to do the following in my JS:
Echo.channel('laravel_database_public').listen('MessageSent', ({message}) => {
console.log(message);
});
But ofcourse, I want to remove the prefix (or figure out why its there). Hopefully someone can clear this up for me. Thanks in advance.

Answer 1

This is configurable in config/database.php (and I believe even removable) under
'redis' => [
'options' => [
'prefix' => // change here.
]
]

Answer 2

The accepted answer does not work with laravel-echo-server.
The solution is rather to let the whole Redis Laravel config untouched and to run version ^1.6.0 of laravel-echo-server with the proper keyPrefix option in laravel-echo-server.json config file:
{
"databaseConfig": {
"redis": {
"keyPrefix": "laravel_database_"
}
}
}

As at Laravel 7, the config/database.php looks like this
'redis' => [
'client' => env('REDIS_CLIENT', 'predis'),
'options' => [
'cluster' => env('REDIS_CLUSTER', 'redis'),
'prefix' => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_') . '_database_'),
],
]
So it searches the .env file for your REDIS_PREFIX variable, if there's none, then it generates laravel_database_ or based on whatever you set APP_NAME to in your .env file.
All you have to do is set your REDIS_PREFIX. You can leave it empty so that there is no prefix at all.
