Command line interface for ajv that utilizes any-json to provide validation against many data formats. pajv
can validate: CSON, Hjson, JSON, JSON5, TOML, and YAML files using JSON Schema. pajv is a fork of ajv-cli.
npm install -g pajv
pajv help
pajv help validate
pajv help test
This command validates data files against JSON-schema
pajv validate -s test/schema.json -d test/valid_data.json
pajv -s test/schema.json -d test/valid_data.json
You can omit validate
command name.
Only one schema can be passed in this parameter
Multiple data files can be passed, as in -r
parameter:
pajv -s test/schema.json -d "test/valid*.json"
If some file is invalid exit code will be 1.
The schema in -s
parameter can reference any of these schemas with $ref
keyword.
Multiple schemas can be passed both by using this parameter mupltiple times and with glob patterns. Glob pattern should be quoted and extensions cannot be omitted.
Schemas can use any of these schemas as a meta-schema (that is the schema used in $schema
keyword - it is used to validate the schema itself).
Multiple meta-schemas can be passed, as in -r
parameter.
You can pass module(s) that define custom keywords/formats. The modules should export a function that accepts Ajv instance as a parameter. The file name should start with ".", it will be resolved relative to the current folder. The package name can also be passed - it will be used in require as is.
For example, you can use -c ajv-keywords
to add all keywords from ajv-keywords package or -c ajv-keywords/keywords/typeof
to add only typeof keyword.
-
--errors=
: error reporting format. Possible values:js
(default): JavaScript objectjson
: JSON with indentation and line-breaksline
: JSON without indentaion/line-breaks (for easy parsing)text
: human readable error messages with data paths
-
--changes=
: detect changes in data after validation.
Data can be modifyed with Ajv options--remove-additional
,--use-defaults
and--coerce-types
).
The changes are reported in JSON-patch format (RFC6902).
Possible values arejs
(default),json
andline
(see--errors
option).
This command asserts that the result of the validation is as expected.
pajv test -s test/schema.json -d test/valid_data.json --valid
pajv test -s test/schema.json -d test/invalid_data.json --invalid
If the option --valid
(--invalid
) is used for the test
to pass (exit code 0) the data file(s) should be valid (invalid).
This command supports the same options and parameters as validate with the exception of --changes
.
