## Function: resolveHelper()

A helper function for implementing the [Resolver.resolve](/twine-js/twine-protocol/twine-core/interfaces/resolver.md#resolve) method

### Param

The fetchers to use

### Param

The query to resolve

### Param

Options for the resolution

### See

* [MemoryStore.resolve](/twine-js/twine-protocol/twine-core/classes/memorystore.md#resolve) for an example of how to use this
* [ResolveCallers](/twine-js/twine-protocol/twine-core/type-aliases/resolvecallers.md)

### Example

```js
class MemoryStore {
  async resolve(query: IntoResolveChainQuery, options?: ResolveOptions): Promise<ChainResolution>
  async resolve(query: IntoResolvePulseQuery, options?: ResolveOptions): Promise<PulseResolution>
  async resolve(query: any, options?: ResolveOptions) {
    return resolveHelper({
      fetchChain: ({ chainCID }) => this.fetch(chainCID) as Chain | null,
      fetchPulse: ({ pulseCID }) => this.fetch(pulseCID) as Pulse | null
    }, query, options)
  }
  //...
}
```
