NAME

Data::Sah::JS - Some functions to use JavaScript Sah validator code from Perl

VERSION

This document describes version 0.87 of Data::Sah::JS (from Perl distribution Data-Sah-JS), released on 2016-09-14.

SYNOPSIS

use Data::Sah::JS qw(gen_validator);

my $v = gen_validator(["int*", min=>1, max=>10]);

# validate your data using the generated validator
say "valid" if $v->(5);     # valid
say "valid" if $v->(11);    # invalid
say "valid" if $v->(undef); # invalid
say "valid" if $v->("x");   # invalid

# generate validator which reports error message string, in Indonesian
my $v = gen_validator(["int*", min=>1, max=>10],
                      {return_type=>'str', lang=>'id_ID'});
say $v->(5);  # ''
say $v->(12); # 'Data tidak boleh lebih besar dari 10'
              # (in English: 'Data must not be larger than 10')

DESCRIPTION

FUNCTIONS

None exported by default.

gen_validator($schema, \%opts) => CODE (or STR)

Generate validator code for $schema. This is currently used for testing purposes only, as this will first generate JavaScript validator code, then generate a Perl coderef that will feed generated JavaScript validator code to a JavaScript engine (currently node.js) via command-line. Not exactly efficient.

Known options (unknown options will be passed to JS schema compiler):

• source => BOOL (default: 0)

  If set to 1, return JavaScript source code string instead of Perl coderef. Usually only needed for debugging (but see also $Data::Sah::Log_Validator_Code and LOG_SAH_VALIDATOR_CODE if you want to log validator source code).

ENVIRONMENT

LOG_SAH_VALIDATOR_CODE
