Hapi Joier

Better Joi error messages for your 400 responses.

Usage

Just register hapi-joier and be hapi.

server.register({
  register: require('hapi-joier'),
  options: {
    enable: true
  }
})

Now your 400 replies should have better information about the invalid data.

{
  "statusCode":400,
  "error":"Bad Request",
  "message":"child \"name\" fails because [\"name\" length must be at least 10 characters long]",
  "validation":[
    {
      "message":"\"name\" length must be at least 10 characters long",
      "path":"name",
      "type":"string.min",
      "context":{
        "limit":10,
        "key":"name"
      }
    }
  ]
}

As you can see, we can now detect which test failed, this is much better to display the correct error message in the frontend.

Installation

Install this module with the command npm install --save hapi-joier, after that you are ready to register this module as a Hapi plugin.

Testing

Type the following lines inside your command line.

git clone [email protected]:alanhoff/node-hapi-joier.git
cd node-hapi-joier
npm install
npm test

Configuration

Every configuration can be made when you server.register or individually on each route.

• enable Boolean Enable hapi-joier, if used in the server.register it will enable the plugin for every route. Default: false
• map Function The function used to construct each validation object inside de response. It receives a Joi detail as the first parameter.

Examples

Enable hapi-joi for only one route:

// Do not pass "enable" as a option, so it won't be globally enabled
server.register(require('hapi-joi'), function()...);

server.route({
  method: 'GET',
  path: '/upload',
  method: function(request, reply){
    reply('Hello world!');
  },
  config: {
    plugins: {
      joier: {
        enable: true
      }
    }
  }
});

Change the response object with a custom map

// Do not pass "enable" as a option, so it won't be globally enabled
server.register(require('hapi-joi'), function()...);

server.route({
  method: 'GET',
  path: '/upload',
  method: function(request, reply){
    reply('Hello world!');
  },
  config: {
    plugins: {
      joier: {
        enable: true,
        map: function(detail){
          return 'Something is wrong with ' + detail.path;
        }
      }
    }
  }
});

Enable Joier for all routes and intercept every Bomm + Joi response:

server.register({
  register: require('hapi-joi'),
  options: {
    enable: true
  }
}, function()...);
