# Caching

Caching is the technique of temporarily storing query results or data for use in future requests without querying the database each time.

TypeORM has built-in caching support, and you can customize how caching is used.

```
const users = await userRepository

    .createQueryBuilder("user")

    .cache(true) // Enable caching

    .getMany()
```

Additionally, you can configure cache duration or use external caching tools like Redis for better efficiency.

```
const dataSource = new DataSource({

    type: "mysql",

    host: "localhost",

    port: 3306,

    username: "test",

    password: "test",

    database: "test",

    cache: {

        type: "redis",

        options: {

            host: "localhost",

            port: 6379,

        },

    },

})
```
