@lucid-softworks/schema-core

The small contract shared by the Lucid schema ecosystem. It provides path-aware parsers, safe Result parsing, thrown SchemaError parsing, type inference helpers, and inspectable definitions used by adapters.

import {
  createSchema,
  parseFailure,
  parseSuccess,
  schemaIssue,
} from "@lucid-softworks/schema-core";

const positive = createSchema<number, number>(
  (input, path) =>
    input > 0
      ? parseSuccess(input)
      : parseFailure(schemaIssue("positive", "Must be positive", path)),
  { kind: "positive" },
);

positive.parse(1); // 1
positive.safeParse(-1); // Err<SchemaError>
