# Common Selectors Much like @ngrx/entity, when you build state for a new entity with NgRx Auto-Entity we provide a set of ready-made common selectors. These selectors allow you to retrieve the state Auto-Entity manages for you. {% hint style="info" %} We have attempted to maintain compatibility with @ngrx/entity here, so we include the core standard set of selectors that are provided by that framework. {% endhint %} {% hint style="success" %} To name a few\... * selectAll * selectEntities * selectIds * selectTotal * ... {% endhint %} These selectors are returned from our `buildState` utility function as a `ISelectorMap`. See the reference documentation for the full interface definition and the complete list of selectors. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
