node.js - npm prompt user for password behind corporate proxy -

when using npm behind corporate proxy have need have following configurations in .npmrc file in user home directory. proxy = http://<username>:<pass>@<proxy_host>:<proxy_port>/ registry = http://registry.npmjs.org/ https-proxy = http://<username>:<pass>@<proxy_host>:<proxy_port>/ while works fine, there need hardcode password in .npmrc file. corporate password change policy mandates change password after period of time. is there way/configuration prompt user password instead of having in .npmrc file. may way works git clone asks password while cloning if repository password protected. you can install sync-prompt module: npm install sync-prompt and modify npm-registry-client/index.js slightly. see article details , code need add: https://mikesharp.wordpress.com/2014/04/16/getting-npm-to-prompt-for-username-and-password-pochack/

is there way or extension exclude tier pricing discounts when shopping cart discounts applied? basically want avoid customer receiving both discounts. i shopping cart discounts apply original price. for example; original rice $35 - 20% = $7.00 discount ($28.00 per unit) multi-buy 2 units changes original price $33.60 $33.60 -20% = $6.72 discount (1 unit @ $26.88 + 1 unit @ $33.60) = $60.48 the main problem face if user selects different flavours. here user receives tier discount 16% , further 20% on each unit. i can't afford loosing money when happens. $29.40 - 20% = $5.88 = $23.52 per unit therefore if shopping cart discount on rides tier discount , applied original price $35 not problem. customer pay $28.00 minimum units , flavours. in conclusion; shopping cart rules need apply original price only, excluding tier price discounts. please suggest me idea.

javascript - Array sorting in Front-end or Back-end -

i implementing restful api returns array. want know if more efficient sort array in descending order in backend code or in javascript? your api used n clients. performance-wise make sense have each client sorting on own instead of having server n clients. simply, less cpu work server. furthermore, whether result needs sorted or not depends on nature of application using data. let application decide that. however not overthink performance part before have performance problem. data sorting not costly or sorting has been done depending on how information kept internally (in dbms-s, example). edit with 20 rows without sorting, makes no important difference - make api implementing developers' life easier , small sorting on backend side.
