v3.1.0

Features

• Added the new allOf() decoder (docs).
  Note: An allOf decoder existed in v2+, but it did not behave as expected. This new version merges all provided decoders and infers the merged type.

Enhancements

• Improved the literal() decoder type safety, which now infers the literal type instead of a broad type.

Example:

v3.0.0

JsonDecoder.literal('hello') // Decoder<string>

v3.1.0

JsonDecoder.literal('hello') // Decoder<'hello'>

v3.0.0

Release v3 of ts.data.json

This release contains a bug fix contributed by @mlocati 🎉

v2.1.0

Feature

• Added FromDecoder<D> to infer types from decoder declarations. (docs)

Without FromDecoder

  lastname: string;
};

const userDecoder = JsonDecoder.object<User>(
  {
    firstname: JsonDecoder.string,
    lastname: JsonDecoder.string
  },
  'User'
);

With FromDecoder

const userDecoder = JsonDecoder.object(
  {
    firstname: JsonDecoder.string,
    lastname: JsonDecoder.string
  },
  'User'
);
type User = FromDecoder<typeof userDecoder>;
