jsonriver is a small, dependency-free TypeScript library that parses JSON incrementally as it streams in, yielding a sequence of increasingly complete values via an async iterable. It is fully spec-compliant, guaranteeing the final value matches JSON.parse, and works in any modern JavaScript environment.

Use cases

• parse json from a streaming network request incrementally
• render structured output from an llm as it streams
• process large json files without loading them fully into memory
• show partial json results in a ui while data is still arriving
• incrementally parse json in the browser or node without dependencies

When to choose

• you need to display or act on json values before the full payload arrives, e.g. streaming llm output
• you want a tiny (~2.5KiB), zero-dependency parser that works anywhere modern JS runs
• you need strict JSON.parse-equivalent correctness including error handling on invalid input

When to avoid

• you just need to parse complete JSON strings, where JSON.parse is simpler and built-in
• you need to parse formats other than JSON
• you cannot consume async iterables in your runtime environment
