jsonlint-tree

2.0.1 verified Fri May 01 auth: no javascript

A recursive directory JSON validator using jsonlint. Version 2.0.1 requires Node >=18.17, removes extra dependencies from v1, and outputs a summary of valid/invalid files. It differs from other JSON linters by operating recursively on directories rather than single files, providing a clear CLI output with counts. Maintained by educastellano.
