node.js - How to use multiple subdomains and angular apps with nodejs -


i want able use multiple, dynamic subdomains, account holders, while having api subdomain. below:

https://example.com --> angular 4 public landing page app https://api.example.com --> nodejs api https://otbs.example.com --> angular 4 saas application https://test-account.example.com --> angular 4 saas application

the public landing page app angular 4 app public facing application, whereas saas application actual application itself, when users logged in, , mapped subdomain per linked account.

i using nodejs, express 4, angular 4, , angular cli. intention use s3 serving client angular applications, while having nodejs api run in elasticbeanstalk.

is configuration possible? have looked in virtual hosting on aws, isn't i'm looking need ability register new subdomain every time new account created.

we have done using aws cloudfront wildcard dns mapping through route53. approach map *.example.com cloudfront distribution , use override record set api.example.com api in route53 api pointed express webserver. steps follows.

  • when user creates account can store assigned subdomain(virtual) them in backend.
  • after user logs in through login (login.example.com) page he/she redirected subdomain token or cookie.
  • optionally if single user needs in multiple subnets can provide option select after login or go default 1 user can switch internally.

here subdomain merely mask actual mapping validates backend. regardless of subdomain if user goes subdomain angular app loads since wildcard validated api requests , relevant messages can shown users.

also can connect api same cloudfront distribution behavior redirect (e.g api/*) angular app doesn't cors issue.

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() .
