# portalSqliteCache

> SQLite cache for Portal responses

Create SQLite cache for Portal responses. Use with `evmPortalSource` to cache Portal API responses locally.

```ts theme={"system"}
portalSqliteCache(config: { path: string }): PortalCache
```

**Example:**

```ts theme={"system"}
import { portalSqliteCache } from "@subsquid/pipes/portal-cache/node";
import { evmPortalSource } from "@subsquid/pipes/evm";

const source = evmPortalSource({
  portal: "https://portal.sqd.dev/datasets/ethereum-mainnet",
  outputs: evmDecoder({ range: { from: 0 }, events: {} }),
  cache: portalSqliteCache({ path: "./cache.sqlite" }),
});
```

<Note>
  Import from `@subsquid/pipes/portal-cache/node` instead of `@subsquid/pipes/portal-cache`.
</Note>

### When to Use
