ts-decoder v3.0.0

ts-decoder

A functional, opinionated, TypeScript library for decoding arbitrary inputs into type-safe objects

Some features of ts-decoder:

• Functional-style: no classes except for DecodeError, all operations are data-last for easier composition
• Built in decoders for basic types: boolean, number, string and date
• Support for typed array and iterable decoding
• Support for object decoding
• Provides a base DecoderError class to distinguish decoding errors from any other error
• Provides a very simple Decoder TS interface (type Decoder<T> = (input: any) => T). Bulding a custom decoder is very easy.
• Supports decoding nested array, iterable and object structure either fully or partially.
• Provides a mechanism for collecting decoding errors on nested structures without aborting the decoding process (functional-style error bubbling).
• Strict or forced decoding. Strict mode checks for types to be exactly as expected. Forced decoding attempts to map the input to the output type.
