includes 2 parts:
ht-server
: for nodejs serverht-client
: for nodejs or browser client
Installation
Using npm(ES6 module):
Note: ht-server
depends on @hapi/hapi
.
Note: ht-client
depends on axios
.
npm i w-comor-hapi
Example for ht-server
:
Link: [dev source code]
import HtServer from 'w-comor-hapi/dist/ht-server.umd.js'
function random(min, max) {
return Math.floor(Math.random() * max) + min
}
let opt = {
port: 8080,
apiName: 'api',
authenticate: function(token) {
//authenticate user by token
return new Promise(function(resolve, reject) {
setTimeout(function() {
resolve(true)
}, 1000)
})
},
filterFuncs: function(token, funcs) {
//resolve funcs by authenticating user
return new Promise(function(resolve, reject) {
funcs = funcs.filter(function(v) {
return v.indexOf('Hide') < 0
})
resolve(funcs)
})
},
onClientChange: function(clients, opt) {
console.log(`Server[port:${opt.port}] now clients: ${clients.length}`)
},
funcs: {
'group.plus': function({ p1, p2 }) {
return new Promise(function(resolve, reject) {
setTimeout(function() {
resolve(p1 * p2)
}, random(100, 3000))
})
},
'group.div': function({ p1, p2 }) {
return new Promise(function(resolve, reject) {
setTimeout(function() {
resolve(p1 / p2)
}, random(100, 3000))
})
},
'add': function({ p1, p2 }) {
return new Promise(function(resolve, reject) {
setTimeout(function() {

}, random(100, 3000))
})
},
'addHide': function({ p1, p2 }) {
return new Promise(function(resolve, reject) {
setTimeout(function() {

}, random(100, 3000))
})
},
},
routes: [

method: 'GET',
path: '/code',
handler: function (req, res) {
//console.log(req)
return 'get code query: ' + JSON.stringify(req.query)

new HtServer(opt)
Example for ht-client
:

},
reconn: function() {

},
}
//HtClient
new HtClient(opt)
.then(function(wo) {
console.log('client nodejs: funcs: ', wo)
function core(ps) {
wo.group.plus(ps)
.then(function(r) {
console.log('client nodejs: plus(' + JSON.stringify(ps) + ')=' + r)

})
.catch(function(err) {
console.log('client nodejs: minu: catch: ', err)
})
}
let i = 100
setInterval(function() {
i += 1
core({
p1: i,
p2: 10,
})
}, 1000)
})
.catch(function(err) {
console.log('client nodejs: catch: ', err)
})
In a browser(UMD module):
Note: ht-client
depends on axios
.
[Optional] Add script with nomodule for IE11.
<script nomodule src="https://cdn.jsdelivr.net/npm/@babel/polyfill/dist/polyfill.min.js"></script>
[Necessary] Add script for axios.
<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
[Necessary] Add script for ht-client.
<script src="https://cdn.jsdelivr.net/npm/w-comor-hapi@1.0.12/dist/ht-client.umd.js"></script>
