Opened this issue · 6 comments
i am new in hapi and i really like your boilerplate api but i don't know how can i add plugin
for example i want to add hapi-io plugin for socket and i should put this lines
server.register({
register: require('hapi-io'),
options: {
...
}
});
exports.register = function(server, options, next) {
var io = server.plugins['hapi-io'].io;
};
where should i put them
can you help me i really need your help @devinivy
Hey @mostafa-raafat
See how Dogwater is registered in server/manifest.js. You'll have to add your registration in the registrations array. Something like:
registrations: [
{
plugin: {
register: 'hapi-io',
options: {}
}
}
]
thank you @WilliamSWoodruff for reply
i make it like you said but i get an error when i try to put
let io = server.plugins['hapi-io'].io;
io.emit('connection', function (socket) {
socket.emit('connected',"Welcome");
});
in index.js file
let io = server.plugins['hapi-io'].io;
TypeError: Cannot read property 'io' of undefined
The boilerplate is split between a plugin (in lib/) and a server (in server/) to deploy that plugin. If you'd like to register hapi-io in your plugin, simply add a file lib/plugins/hapi-io.js that exports options for hapi-io in the form { options: {/* hapi-io options */} }. haute-couture will then register that plugin for you, and you should be able to access server.plugins['hapi-io'] inside haute-couture's callback in lib/index.js. If you'd like to register hapi-io to your server as @WilliamSWoodruff indicated, I would suggest using server.dependency() (with a callback) within your plugin to ensure hapi-io has been registered before you try to access server.plugins['hapi-io'].
what i want to make to say on connection emit connected
and on add user for example make some thing that's all
routes/user.js look like this
'use strict';
const Joi = require('joi');
const Boom = require('boom');
let addedUser = false;
let userList = [];
module.exports = [
{
method: 'get',
path: '/user',
config: {
tags: ['api'],
plugins: {
'hapi-io': 'get-users'
},
handler: (request, reply) => {
let io = request.plugins['hapi-io'].io;
let socket = request.plugins['hapi-io'].socket;
if (socket) {
socket.emit('get-users', userList);
}
reply({success: true});
}
}
},
{
method: 'post',
path: '/user',
config: {
tags: ['api'],
plugins: {
'hapi-io': 'add-user'
},
validate: {
payload: {
username: Joi.string().alphanum().min(3).max(30).required()
}
},
handler: (request, reply) => {
let io = request.plugins['hapi-io'].io;
let socket = request.plugins['hapi-io'].socket;
if (socket) {
if (addedUser) return;
addedUser = true;
socket.username = request.payload.username;
userList.push({username: request.payload.username});
socket.emit('login', {userList: userList});
socket.broadcast.emit('user-joined', {
username: request.payload.username
});
}
reply({success: true});
}
}
},
{
method: 'delete',
path: '/user',
config: {
tags: ['api'],
plugins: {
'hapi-io': 'disconnect'
},
handler: (request, reply) => {
let io = request.plugins['hapi-io'].io;
let socket = request.plugins['hapi-io'].socket;
if (socket) {
if (addedUser) {
for (let i = 0; i < userList.length; i++) {
if (socket.username === userList[i].username) {
userList.splice(i, 1);
}
}
socket.broadcast.emit('user-left', {
username: socket.username
});
}
}
reply({success: true});
}
}
},
];
index.js look like this
'use strict';
const Package = require('../package.json');
const HauteCouture = require('haute-couture')();
exports.register = (server, options, next) => {
HauteCouture(server, options, (err) => {
if (err) {
return next(err);
}
let io = server.plugins['hapi-io'].io;
io.emit('connection', function (socket) {
socket.emit('connected',"Welcome");
});
next();
});
};
exports.register.attributes = {
pkg: Package
};
i think i did something wrong i get
socket.on(event, function(data, respond) {
^
TypeError: socket.on is not a function

That seems to be an issue with hapi-io or the way you're using it, which I don't know much about– sorry, don't think we can help you with that!
