Installation

With npm:

npm install --save optics-ts

With yarn:

yarn add optics-ts

Requirements

TypeScript >= 4.1 and the strictNullChecks compiler option are required.

I strongly recommend enabling all strict options in your project's tsconfig.json:

{
  "compilerOptions": {
    "strict": true
  }
}

If this is not possible for your project, enable only the strictNullChecks option:

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}
