node.js - "npm --save install <module>" without actually installing the module -

-

for development setup, i'm using node.js inside docker container. i'm placing node_modules folder in docker image avoid potential problems caused architectural differences between non-linux host , docker engine. whenever add module, rebuild image, process invokes npm install within container. add dependency package.json, run npm --save install <module> on host computer since that's i'm editing files. installs module onto host computer doesn't need it. it's waste of time , bandwidth.

i manually edit package.json, that's error-prone , requires looking module's version number. there way make change through npm while avoiding unneeded installation?

when docker container running can run npm install inside container:

docker exec -ti <container id or name> npm install --prefix ./path/to/your/app <package> --save

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
