## README

# Hyperjump - JSON Schema Formats 

A collection of validation functions for the JSON Schema `format` keyword.

## Install

This module is designed for Node.js (ES Modules, TypeScript) and browsers. It
should work in Bun and Deno as well, but the test runner doesn't work in these
environments, so this module may be less stable in those environments.

### Node.js

```bash
npm install @hyperjump/json-schema-formats
```

### TypeScript

This package uses the package.json "exports" field. [TypeScript understands
"exports"](https://devblogs.microsoft.com/typescript/announcing-typescript-4-5-beta/#packagejson-exports-imports-and-self-referencing),
but you need to change a couple settings in your `tsconfig.json` for it to work.

```jsonc
    "module": "Node16", // or "NodeNext"
    "moduleResolution": "Node16", // or "NodeNext"
```
