tinytinyjson5
Run the checks yourself
The scripts that rerun the tests, the fuzzers, the size and the benchmarks.
Run these from packages/tinyjson5 in the repository. tinyjson5 uses pnpm 12, Node 26, and Vite+ (vp) for formatting, linting, tests, and the build. tsrs does the typecheck.
pnpm install
pnpm ready # format, build, lint, typecheck, and test
pnpm corpus:fetch # json5-tests, into .cache, so the conformance tests run
pnpm json5:fetch # json5 2.2.3, into .cache, for the large benchmark input
pnpm json5-tests # json5's own tests against json5 and tinyjson5
pnpm corpus # every json5-tests case against json5
pnpm fuzz 200000 3 # 200,000 mutated inputs with seed 3
pnpm fuzz:stringify 10000 1 # 10,000 random values through every option
pnpm unicode # identifier characters that differ from json5's tables
pnpm size # bundle sizes next to json5
pnpm bench # speed next to json5
