Check project constraints

yarn constraints

This command runs constraints on your project and reports each unmet rule. If any error remains, the command exits with a non-zero exit code.

If the --fix flag is used, Yarn attempts to automatically fix unambiguous issues through a multi-pass process capped at 10 iterations. Some ambiguous patterns cannot be autofixed; in those cases, you must manually specify the right resolution.

Constraints are configured through JavaScript or TypeScript constraint files.

#--fix, -fboolean

Attempt to automatically fix unambiguous issues, following a multi-pass process

#--jsonboolean

Format the output as an NDJSON stream
