# SADD

> Add one or more members to a set

Add one or more members to a set stored at key. Members that already exist in the set are ignored. If the key does not exist, a new set is created.

## Usage

```typescript theme={null}
await redis.sadd(key, member, ...members);
```

## Parameters

<ParamField body="key" type="string" required>
  The key of the set
</ParamField>

<ParamField body="member" type="TData" required>
  The first member to add to the set
</ParamField>

<ParamField body="members" type="TData[]">
  Additional members to add to the set
</ParamField>

## Response

<ResponseField name="result" type="number">
  The number of elements that were added to the set, not including elements already present
</ResponseField>

## Examples

### Add a single member

```typescript theme={null}
const result = await redis.sadd("myset", "hello");
console.log(result); // 1
```

### Add multiple members

```typescript theme={null}
const result = await redis.sadd("fruits", "apple", "banana", "orange");
console.log(result); // 3
```

### Add duplicate members

```typescript theme={null}
await redis.sadd("colors", "red", "blue");
const result = await redis.sadd("colors", "red", "green");
console.log(result); // 1 (only "green" was added)
```

### Using with custom types

```typescript theme={null}
const result = await redis.sadd("numbers", 1, 2, 3, 4, 5);
console.log(result); // 5
```
