mongoose-errors-handler-i18n
Express/Node.js module to create internationalized formatted errors in Mongoose. 🇫🇷🇺🇸
mongoose-i18n-error is a lightweight module for node.js/express.js to create beautiful mongoose i18n validation error messages. It is built on top of the awesome i18n-node translation module.
username: type: 'required' message: 'is required' value: undefined email: type: 'regexp' message: 'is no valid email' value: 'johndoe.de'
Usage
npm install mongoose-errors-handler-i18n --save
Configure your app to support i18n:
var i18n = ; i18n; app;
Then, simply add the module as an express error handler middleware:
var i18nMongooseError = new ; app;
Options
By default, the plugin will prefix the error messages in your locale files with 'error.'
:
"error.required": "is required""error.minlength": "needs a minimum length of %s""error.user.password.regexp": "is no valid email""error.cast": "is not valid"
You can change the prefix by passing the prefix attribute as options:
var i18nMongooseError = new prefix: 'err.';
Custom validators
In your custom mongoose validators your error message should now apply to the key in your locales.
var Schema = name: type: String validate: { return /^[A-Z]*$/i; } message: 'user.name.alpha' // or 'alpha' ;
Tests
To run the tests you need a local MongoDB instance available. Run with:
npm test
