Provides a compact, spec-compliant way to parse and serialize TOML configuration files into JavaScript objects, removing the friction of handling TOML syntax, date/time semantics, and parse diagnostics across runtimes.
Read a config.toml file, parse it into a JavaScript object, update the configuration values, and write it back to disk using the library's parse and stringify functions.

You can parse and serialize TOML configuration files in JavaScript by mapping TOML text into JavaScript objects and back, preserving date/time semantics and correctly emitting arrays and tables. This allows programmatic reading and updating of config files.
TOML parsing in JavaScript preserves date and time semantics using TomlDate, which handles all TOML date/time variants. When serializing back to TOML, the TomlDate formats are correctly maintained in the output.
You can get line and column numbers from a TOML parse error using TomlError, which provides precise diagnostics and a code snippet pointer. This surfaces exact locations for robust error reporting during config loading and validation.
You can parse TOML in JavaScript runtimes including Bun, Node, Deno, and ESM browsers. This cross-runtime support makes TOML parsing suitable for CLI tools, application config loading, and build-time tooling across different environments.
When parsing TOML into JavaScript objects, integers map to number or bigint for out-of-range values, while arrays must be homogeneous. The parser strictly rejects undefined, null, mixed arrays, and circular references to ensure valid data structures.
When serializing JavaScript objects to TOML, the serializer rejects undefined, null, mixed arrays, and circular references. It enforces homogeneous arrays and correctly emits TomlDate formats, arrays, tables, and array-of-tables for valid TOML output.
