@grinstead/cddl

Validate CDDL files from the command line and in Node.js.

The parser is based on the RFC 8610 Appendix B grammar. Source-of-truth is ABNF in src/grammar/cddl.abnf, which is converted to Peggy in build steps.

CLI

npx @grinstead/cddl validate schema.cddl

On success:

valid CDDL: schema.cddl

On failure, output includes line and column when available.

You can validate multiple files in one call:

npx @grinstead/cddl validate a.cddl b.cddl

You can also validate from standard input:

cat schema.cddl | npx @grinstead/cddl validate -
