var Express = require('express');
var BodyParser = require('body-parser');
var ExpressJoi = require('express-joi-validator');
var Joi = require('joi');

var app = Express();
app.use(BodyParser.json());

// Use Joi to create your schemas
var querySchema = {
query: {
limit: Joi.number().default(10).min(10).max(100),
offset: Joi.number().default(10).min(10).max(100)
}
};

// Attach the validator like other middleware
app.get('/', expressJoi(querySchema), function (req, res, next) {
// do something with req.query.limit & req.query.offset
...
});

// Use Joi to create your schemas
var bodySchema = {
body: {
name: Joi.string().required()
}
};

// Attach the validator like other middleware
app.post('/', expressJoi(bodySchema), function (req, res, next) {
// do something with req.body;
...
});

// Example error handler
app.use(function (err, req, res, next) {
if (err.isBoom) {
return res.status(err.output.statusCode).json(err.output.payload);
}
});
