mongoose-i18n-error's Issues

Exception during parsing unique error of MongoDB

When I insert a duplicated record, Mongo (version 3.4.0) raises this exception:

TypeError: Cannot read property '1' of null\n at parseUniqueError (/app/node_modules/mongoose-i18n-error/index.js:78:17)

In that line of code, mongoose-i18n-error accesses the matches of the regex that it used in order to recover the field name and its value from the error message sent by mongo.

The message that I receive from Mongo is:

E11000 duplicate key error collection: mydb.users index: phone_1 dup key: { : "[phone]" }

And the current regex is:

var matches = /index:\s..$(.)_1\sdup key:\s{\s:\s"(.*)"\s}/.exec(err.message);

Maybe this version of mongo sends a different error message from what you were expecting.

This regex solves the problem:

var matches = /index:\s(.)_1\sdup key:\s{\s:\s"(.)"\s}/.exec(err.message);

but I don't know if it's always correct in any version of mongo.

Would you mind to take a look?
Thanks

lacks clarity on how to use

i was confused going through the read.me file ; where am I suppose to define this code snippet ?

{
    username: {
        type: 'required',
        message: 'is required',
        value: undefined
    },
    email: {
        type: 'regexp',
        message: 'is no valid email',
        value: 'johndoe.de'
    }
}

it would be very helpful if you had a working example. Thanks!
