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.
