# Redis
ToolJet can run Redis commands on your Redis instances.
## Connection
ToolJet requires the following to connect to your Redis instances.
- **Host**
- **Port** - The default port for Redis server is 6379
- **Username**
- **Password**
Click on "Test" button to test the connection and click "Save" to save the data source.
## Redis Queries
Here are some examples of Redis commands and their usage. You can refer to the [Redis Official Documentation](https://redis.io/commands) for a complete list of supported commands.
### PING Command
The `PING` command is used to test the connection to Redis. If the connection is successful, the Redis server will respond with `PONG`.
```shell
PING
```
### SET Command
The `SET` command is used in Redis to assign a value to a specific key.
```shell
SET key value
```
**Example 1/2:**
When the input value contains spaces, you should encode the value before providing it as an input:
```shell
SET products {{encodeURI('John Doe')}}
```
### GET Command
The `GET` command is used in Redis to retrieve the value associated with a specific key.
```shell
GET key
```
**Example 2/2:**
To retrieve a value that was previously encoded while setting, you can use transformations.
- Enter the GET command in the editor:
```shell
GET products
```
- Enable Transformations (JS) and use `decodeURI`:
```js
return JSON.parse(decodeURI(data));
```
