Data Validation (CLI)#

The data-validation folder contains a CLI tool that validates SurveyJS submissions using SurveyJS’ own survey-core validator. The tool is used by the server when Force Server Side Validation is enabled.

CLI usage#

bun validate.mjs \
  --schema-json ./survey.json \
  --form-json ./data-valid.json \
  --result-json ./output.json

Required options:

  • --schema-json: SurveyJS form JSON

  • --form-json: Submission JSON

Optional:

  • --result-json: Output file (defaults to output.json)

Output#

The output JSON contains a valid boolean and a list of per-question errors. The process exits with status 0 on success and 1 on validation failure.

Building binaries#

Deno binaries are built with:

make deno-mac
make deno-linux

Binaries are placed in data-validation/dist. See data-validation/README.md for full build instructions.
