history
Project history and usage
Typical is a data-interchange and serialization framework centered on algebraic data types. It defines schemas, then generates serialization and deserialization code for supported languages.
Project history
The public repository was created in March 2021. Its README presents Typical as a comparison point to Protocol Buffers and Apache Thrift, but with a type system emphasizing non-nullable values, exhaustive pattern matching, and safe schema evolution through asymmetric fields.
The README says the design was informed by experience using Protocol Buffers at Google and Apache Thrift at Airbnb, while clarifying that Typical is not an officially supported product of either company.
Adoption history
Official adoption evidence is limited. The batch input lists Homebrew and Nix packages, and GitHub release metadata shows continued releases into 2026, including v0.15.0 in April 2026.
How it is used
Users write a schema file such as `types.t`, run commands like `typical format` or `typical generate`, and produce Rust and TypeScript or JavaScript-facing code for binary-compatible message storage or service boundaries.
Why package nerds care
Typical is interesting to package-focused developers because it packages an opinionated IDL/code-generation stack as a CLI. It sits in the small space between mainstream schema compilers and language-specific serialization libraries, appealing to users who want stronger ADT semantics in generated code.
