# Installation
To install the stable version
```sh
npm i io-ts fp-ts
```
**Note**. [`fp-ts`](https://github.com/gcanti/fp-ts) is a peer dependency for `io-ts`
# Usage
## Stable features
- [Documentation of the main stable features (`index.ts` module)](index.md)
## Experimental modules (version `2.2+`)
Experimental modules (\*) are published in order to get early feedback from the community, see these tracking [issues](https://github.com/gcanti/io-ts/issues?q=label%3Av2.2+) for further discussions and enhancements.
The experimental modules are **independent and backward-incompatible** with stable ones.
- [`Decoder.ts` module](Decoder.md)
- [`Encoder.ts` module](Encoder.md)
- [`Codec.ts` module](Codec.md)
- [`Eq.ts` module](Eq.md)
- [`Schema.ts` module (advanced feature)](Schema.md)
(\*) A feature tagged as _Experimental_ is in a high state of flux, you're at risk of it changing without notice.
