A collection of runtime types and combinators for use with io-ts
To install the stable version:
npm i io-ts-types
Note. io-ts-types
depends on
starting from 0.5.0
you must install fp-ts
, io-ts
and monocle-ts
manually (fp-ts
, io-ts
and monocle-ts
are listed in peerDependency
)
Import specific codecs and combinators directly from the lib
folder, as in:
import { NonEmptyString } from "io-ts-types/lib/NonEmptyString"
In this way, you'll only need to add the monocle-ts
dependency if you import any of the combinators depending on it, like getLenses
The stable version is tested against TypeScript 3.2.2, but should run with TypeScript 3.0.1+ too
Note. If you are running < typescript@3.0.1
you have to polyfill unknown
.
You can use unknown-ts as a polyfill.
