node.js - Webpack builds on production environment -


in react js starter kits 1 @ https://github.com/wallacyyy/reactly-starter-kit, see package.json files have content this:

"scripts": {    "build": "cross-env node_env=production webpack --config ./webpack.prod.config.js --progress --colors", ... }, "dependencies": {   "express": "^4.15.2",   "react": "^15.5.4",   "react-dom": "^15.5.4" }, "devdependencies": {   "webpack": "^2.2.1",   "webpack-dev-server": "^2.4.2" }

the build script uses webpack process production build. how able run on production when webpack devdependency?

webpack doesn't run on production environment. build script sets node_env variable equals production , letting webpack , plugins know should prepare bundle production use. happens when run command depends on webpack configuration, among common things code minification. can specify different kind of source maps , many other things. see https://webpack.js.org/guides/production/ more information.

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() .
