Support for transform mongoose errors to different specifications on Hapi.js
Install
$ npm install hapi-mongoose-errors
Usage
var Hapi = require('hapi');
var server = new Hapi.Server();
server.connection({ port: 8000 });
server.register([{
register: require('hapi-mongoose-connect'),
options: {
mongooseUri: 'mongodb://localhost/my-database'
}
}, {
register: require('hapi-mongoose-models'),
options: {
globPattern: './models/**/*.js',
globOptions: {
cwd: __dirname
}
}
}, {
register: require('hapi-mongoose-request'),
options: {
param: 'model',
capitalize: true,
singularize: true
}
}, {
register: require('hapi-mongoose-errors'),
options: {
specification: 'jsonapi', // Or custom function (err, http) (REQUIRED)
http: 422 // Http code to respond (REQUIRED)
}
}], function (err) {
if (err) {
throw err;
}
server.route({
method: 'POST',
path: '/api/v1/{model}', // The same is declared in the `hapi-mongoose-request` options
method: function (request, reply) {
request.Model.create(request.payload, function (err, doc) {
// If you send a Error object, the plugin will check if can convert to declare specification
reply(err, doc);
});
}
});
server.start(function (err) {
if (err) {
throw err;
}
console.log('Server started at: ' + server.info.uri);
});
}
});
Specifications
For now only support jsonapi. You can implement a custom specification in options:
var Lodash = require('lodash');
var options = {
http: 422,
specification: function (err, http) {
var error = {};
Lodash.each(err.errors, function (validatorError) {
// validationError is a Mongoose.Error.ValidatorError instance
error[validatorError.path] = {
desc: validatorError.toString(),
httpStatus: http
};
});
return error; // New object to send to client
}
};
