airbridge-link-migrator-core

Type-safe utility functions for validation and transformation.

Installation

npm install airbridge-link-migrator-core

Usage

import { required, optional, check, compute } from 'airbridge-link-migrator-core'

// Required value extraction with validation
const value = required.string(input)  // throws if not string
const url = required.string.expression(input, /^https?:\/\//)  // validates with regex

// Optional value extraction (returns undefined if invalid)
const maybeString = optional.string(input)
const maybeNumber = optional.number(input)

// Type checking
if (check.string(value)) {
    // value is string
}

// Schema validation
const result = required.patchSchema({
    name: input.name,
    age: input.age,
}, {
    'name': 'string',
    'age?': 'number',
})

// Conditional computation
compute.defined(value, (v) => {
    // v is guaranteed to be defined
    console.log(v)
})
