tosource: Object to Source Code Converter

tosource is a utility library for JavaScript that serializes complex JavaScript objects, including functions, Date objects, RegExp instances, Maps, Sets, sparse arrays, NaN, Infinity, undefined, and negative zero, into their equivalent JavaScript source code string representations. This extends beyond the capabilities of JSON.stringify, which only handles a subset of these types. The package is currently in a pre-release alpha phase (v2.0.0-alpha.3), indicating active development. It is designed to facilitate sharing trusted data structures and even code between Node.js environments and browsers, useful for isomorphic applications. While there isn't an explicit release cadence, the recent alpha releases suggest ongoing improvements in functionality and toolchain, including TypeScript support and ESM exports.
