# circomlib

[circomlib is a companion repository](https://github.com/iden3/circomlib) to the Circom language officially released and maintained by Iden3. It contains all of the necessary primitives you need for basic operations within your circuits. The circomlib library is similar to [`@openzeppelin/contracts`](https://github.com/OpenZeppelin/openzeppelin-contracts) for Solidity in premise. Accompanying the main circomlib library is the  [`circomlibjs`](https://github.com/iden3/circomlibjs) JavaScript-based library. All components [contained in the circomlib library](https://github.com/iden3/circomlib/tree/master/circuits) can be driven using circomlibjs.\
\
As you begin to extend these templates into your own circuits, make sure to keep [*Anonymous Templates* ](https://github.com/iden3/circom/blob/master/mkdocs/docs/circom-language/anonymous-components-and-tuples.md)in mind. Check out *Circom Language > Components and Templates* *> Anonymous Templates* for an exploration of the shortcut on one-time use of components.

This section only contains the essential, easy-to-use components provided by circomlib. The components not included are for those who do not need BattleZips!

{% hint style="info" %}
The [circomlib repository contains unit testing for all of its templates](https://github.com/iden3/circomlib/tree/master/test). Use them for additional insight into their integration with your circuits.
