Redis Provider#

After you’ve added the Redis Provider package to your project, setting the provider up in code is easy.

Add to Droplet#

First, register the RedisProvider.Provider with your Droplet.

import Vapor
import RedisProvider

let config = try Config()
try config.addProvider(RedisProvider.Provider.self)

let drop = try Droplet(config)

...

Configure Vapor#

Once the provider is added to your Droplet, you can configure Vapor to use Redis for caching.

Config/droplet.json

{
    "cache": "redis"
}

Configure Redis#

If you run your application now, you will likely see an error that the Redis configuration file is missing. Let’s add that now.

Basic#

Here is an example of a simple Redis configuration file.

Config/redis.json

{
    "hostname": "127.0.0.1",
    "port": 6379,
    "password": "secret",
    "database": 2
}

Both password and database are optional.

URL#

You can also pass the Redis credentials as a URL.

Config/redis.json

{
    "url": "redis://:secret@127.0.0.1:6379/2"
}

Both password and database are optional.

Done#

You are now ready to start using Cache with your Redis database.
