javascript - Calling an ES6 class middleware using KOA -


i have function in es6 class i'm trying call middleware no success. in index file, have:

*i have included relevant code

"use strict";     const http        = require('http')     const koa         = require('koa')     const app         = new koa()     const bodyparser  = require('koa-better-body')     const install     = require('./.system/install/install')        const install     = new install()  class index {   /**   * class constructor function   * @class index   * @method constructor   * @return {undefined}   */   constructor () {   }    /**   * main entry method    * @class index   * @method init async   * @return {undefined}   */   async init(){     // install helper     app.use(install.setup)      // response     app.use(async ctx => {       ctx.body = 'hello world';     });      http.createserver(app.callback()).listen(8080);   } }  let init = new index(); init.init()

and in install.js, have:

       "use strict";         const process = require('./library/process')         const fs      = require('async-file')      module.exports = class install {         async setup (ctx, next) {              ctx.body = 'install';         }     }

but koa app keeps giving me 404 not found error. know static method might solve i'd rather not use static methods. install class has both middleware function , standard functions.

you have 404, because don't use koa-router

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
