user-agent-based polyfill combinator

A combinator parser in Typescript inspired by Parsec

general parser like YACC

Validate data with unknown structure

Validatem combinator for marking a hasShape or object literal rule as allowing additional, unspecified properties

Validatem combinator for prepending a certain path to validation errors

Validatem combinator for specifying 'alternatives', and verifying that a value meets at least one of the rules

Validatem combinator for validating that a value has certain keys that pass certain validators (eg. object validation)

Validatem combinator like array-of, but for cases where the values may be in nested (to-be-flattened) arrays

Combinatory logic interpreter in Typescript.

This library is a proof of concept and is not intended for production use. It aims to align an HKT implementation with runtime code. It implements a simple parser combinator library. You can use it to implement a typesafe JSON parser or GraphQL query pars

easier than regex string matching patterns for urls and other strings. turn strings into data or data into strings.

A simple parser combinator library for expressions and domain specific languages, written in Typescript

A library to construct combinators for serializing, deserializing, and validating data
