Usage

Install the package from npm registry as follows:

You must use indicative directly. This is a low level module meant to be used by indicative itself.

npm i indicative-compiler

# yarn
yarn add indicative-compiler

and then use it as follows:

import { Compiler, Executor } from 'indicative-compiler'
import { VanillaFormatter } from 'indicative-formatters'
import * as validations from 'indicative-rules'

const schema = {
  username: 'required',
  email: 'required|email'
}

const messages = {}

// Do it once for each schema
const compiledFunctions = new Compiler(schema, messages).compile()

await new Executor(compiledFunctions).exec(data, VanillaFormatter, false, false)

The Executor.exec function takes 4 parameters.

1. data: The runtime data to validate against the compiled schema.
2. formatter: Formatter constructor to collect and format error messages.
3. bail: When true, it will stop after first error.
4. removeAdditional: When true, the exec will return only validated properties.
