node.js - npm nodejs project with typescript; live build doesn't recompile changed modules -


i found description init nodejs project in typescript here: https://basarat.gitbooks.io/typescript/docs/quick/nodejs.html

this describes way autorecompile onchange, if run code using npm start.

i created project configuration:

tsconfig.json:

{   "compileroptions": {     /* basic options */     "target": "es2015",                          /* specify ecmascript target version: 'es3' (default), 'es5', 'es2015', 'es2016', 'es2017', or 'esnext'. */     "module": "commonjs",                     /* specify module code generation: 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'esnext'. */      "outdir": "./build",                        /* redirect output structure directory. */     /* strict type-checking options */     "strict": true                            /* enable strict type-checking options. */   },   "files":[     "server.ts",     "db/db.ts",     "protocol/protocol.ts"   ]  }

package.json

{   "name": "server",   "version": "1.0.0",   "description": "",   "main": "server.js",   "scripts": {     "start": "npm run build:live",     "build:live": "nodemon --exec node_modules\\.bin\\ts-node -- server.ts",     "test": "echo \"error: no test specified\" && exit 1"   },   "keywords": [],   "author": "",   "license": "isc",   "dependencies": {     "typescript": "^2.4.2"   },   "devdependencies": {     "@types/express": "^4.0.36",     "@types/node": "^8.0.20",     "express": "^4.15.4",     "mysql": "^2.14.1",     "nodemon": "^1.11.0",     "ts-node": "^3.3.0",     "typescript": "^2.4.2"   } }

the reload works fine, if change mainfile server.ts

problem

if change db.ts or protocol.ts, reload performed, db.ts , protocol.ts not recompiled.

any ideas?

i not recommend using nodemon , ts-node dev, instead recommend using tsc-watch.

npm install tsc-watch --save-dev

and in package.json should this:

  "scripts": {     "start": "node ./build/server.js",     "build": "tsc",     "dev": "tsc-watch --onsuccess \"node ./build/server.js\"",   }
  • build building app ready production.
  • start starting app on production.
  • dev compiling , running/re-running node.

remark: script can run using "npm run dev"

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

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() .
