# flagd-core
flagd-core contain the core logic of flagd [in-process evaluation](https://flagd.dev/architecture/#in-process-evaluation) provider.
This package is intended to be used by concrete implementations of flagd in-process providers.
## Usage
flagd-core wraps a simple flagd feature flag storage and flag evaluation logic.
To use this implementation, instantiate a `FlagdCore` and provide valid flagd flag configurations.
```typescript
const core = new FlagdCore();
core.setConfigurations(FLAG_CONFIGURATION_STRING);
```
Once initialization is complete, use matching flag resolving call.
```typescript
const resolution = core.resolveBooleanEvaluation('myBoolFlag', false, {});
```
