restify-api-validation

npm install restify-api-validation --save

Contributition and enhancement to repository are most welcome.

Also you can check examples in the test folder how to write validation and see the below details how to use it. Happy coding.

Also let me know if you want enhancement . Tested with latest node.js version 10.15 +

You can use this like this

file: allValidation.js

'use strict';
var Joi = require('joi');


var validate = {
  login :{
    options: { flatten: true },
    body: {
    email: Joi.string().required().email(),
    password: Joi.string().required().min(6).max(10)
    }
  },
  register : {
  options: { flatten: true },
  body: {
    email: Joi.string().required().email(),
    password: Joi.string().required().min(6).max(10)
  }
}};
module.exports.validate =validate;

file: app.js

'use strict';

const restify = require("restify");
var validate = require('restify-api-validation');
var validation = require('./allValidator').validate;
global.httpErrors = restify.errors;

global.server = restify.createServer();
server.use(restify.plugins.bodyParser());
server.use(restify.plugins.acceptParser(server.acceptable));
server.use(restify.plugins.queryParser({
    mapParams: false
}));
server.use(restify.plugins.fullResponse());

server.on('restifyError', function(req, res, err, next) {
    // handle all errors passed to next here, whether it's Error or NotFoundError or anything that is an instance of Error
   res.status(err.status);
   res.json(err.errors); //res.send(err);
  });

server.listen(3000, function () {
    "use strict";
    console.log("server is up at 3000");
});

// generates a response function sending back to user the specified req[key]
function respondWith (key) {
  return function (req, res) {
    res.json(req[key]);
  };
}

function respond200 (req, res) {
  res.json(200);
}
server.post('/login', validate(validation.login), respond200);
server.post('/register', validate(validation.register), respond200);
// default errorhandler for express-validation
server.use(function (err, req, res, next) {
  res.status(400).json(err);
});


module.exports = server;

#Make sure to use this for error catching , tested in restify 5

server.on('restifyError', function(req, res, err, next) {
    // handle all errors passed to next here, whether it's Error or NotFoundError or anything that is an instance of Error
   res.status(err.status);
   res.json(err.errors); //res.send(err);
  });

For more complex structure like this you can do validation

If you have json structure like this

{
	"email":"himmsharma.99@gmail.com",
	"password":"12345",
	"userinfo":[
		{ "nickname":"himanshu"},
		{"nickname":"himm"}],
	"complexinfo":{
		"name":[
			{"firstname":"ram"},
			{"firstname":"shyam"}]
	}
}

then you can make validation json in the allValidation.js file like this. info is the object like login and register in allValidation.js file . allValidation.js file is above.

var nickname = Joi.object().keys({
  nickname: Joi.string().required()
});

 var firstname = Joi.object().keys({
  firstname: Joi.string().required()
});

While working with header reminder to write in lower case letter.

info : {
  options: { flatten: true ,contextRequest : true},
   headers: {
      authorization: Joi.string().required()
   },
  body: {
    email: Joi.string().required().email(),
    userinfo :Joi.array().items(nickname).required(),
    complexinfo :Joi.object().keys({
                name: Joi.array().items(firstname).required()
                }).required()
  }
}
