Node.js + Docker Compose: node_modules disappears -

-

i'm attempting use docker compose bring number of node.js apps in development environment. i'm running issue, however, node_modules.

here's what's happening:

  1. npm install run part of dockerfile.
  2. i not have node_modules in local directory. (i shouldn't because installation of dependencies should happen in container, right? seems defeat purpose otherwise, since i'd need have node.js installed locally.)
  3. in docker-compose.yml, i'm setting volume source code.
  4. docker-compose build runs fine.
  5. when docker-compose up, node_modules directory disappears in container — i'm assuming because volume mounted , don't have in local directory.

how ensure node_modules sticks around?

dockerfile

from       node:0.10.37  copy       package.json /src/package.json  workdir    /src  run        npm install -g grunt-cli && npm install  copy       . /src  expose     9001  cmd        ["npm", "start"]

docker-compose.yml

api:   build: .   command: grunt   links:     - elasticsearch   ports:     - "9002:9002"   volumes:     - .:/src  elasticsearch:   image: elasticsearch:1.5

due the way node.js loads modules, place node_modules higher in source code path. example, put source @ /app/src , package.json in /app, /app/node_modules they're installed.

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
