Install

Using npm:

npm install ajv-i18n

Usage

In node:

const Ajv = require("ajv") // version >= 8.0.0
const localize = require("ajv-i18n")
// or for JSON Type Definition
// const localize = require("ajv-i18n/localize/jtd")

const ajv = Ajv({allErrors: true, messages: false})
const validate = ajv.compile(schema)
const 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'}))
}

To require only necessary locales (e.g., with browserify):

const localize_ru = require('ajv-i18n/localize/ru')
// or for JSON Type Definition
// const localize_ru = require('ajv-i18n/localize/ru/jtd')

or

const localize = {
  en: require('ajv-i18n/localize/en'),
  ru: require('ajv-i18n/localize/ru'),
}

See Ajv docs for more information.

Tests

npm install
git submodule update --init
npm test

Contributing

Functions that localize error messages are generated using doT template localize.jst, JSON Schema messages and JSON Type Definition messages. Templates are pre-compiled, so doT is not a run-time dependency.

npm run build - compiles functions to localize folder.
