Usage

In node:

var Ajv = require('ajv'); // version >= 2.0.0
var localize = require('ajv-i18n');

// option `i18n` is required for this package to work
var ajv = Ajv({ allErrors: true });
var validate = ajv.compile(schema);
var valid = validate(data);

if (!valid) {
    // ru for Russian
    localize.ru(validate.errors);
    // string with all errors and data paths
    console.log(ajv.errorsText(validate.errors, { separator: '\n' }));
}

var localize_ru = require('ajv-i18n/localize/ru');

or

var localize = {

    ru: require('ajv-i18n/localize/ru')
};

See Ajv docs for more information.

Tests

npm install
git submodule update --init

Contributing

Functions that localize error messages are generated using doT templates in messages and localize.jst template. Templates are precompiled so doT is not a run-time dependency.

npm run build - compiles functions to localize folder.
