node.js - Node how to make dependency analysis and remove unused module dependecies -


my node modules simple module have few dependencies , makes use of built-in modules. given that, module has dependency of module declares dependencies

"dependencies": {     "events": "^1.1.1",     "geocoder": "^0.2.2",     "gpsoauthnode": "^0.0.5",     "istanbul": "^0.4.4",     "protobufjs": "^5.0.1",     "request": "^2.73.0",     "s2geometry-node": "^1.3.0",     "tape": "^4.6.0"   }

running npm install end in following node_submodules tree

that nothing less than

node_modules admin$ du -d0 -h  40m    .

40meg, what? @ first bit surprised of that, since list of dependencies seems much. expect makefile of low level c library boost, libcrypto, libxml, libssl or whatever c/c++ library used os, but, hey wait moment, simple application using built-in library , 1 external dependency. so, what's going on here?

being serious, question is: there way make static analysis of node packages installed via npm? , prune unused dependencies? sure, module not use @ runtime of function declarations in private scope of each of modules, defined in tree.

java - Warning equals/hashCode on @Data annotation lombok with inheritance -

i have entity inherits other. on other hand, i'm using lombok project reduce boilerplate code, put @data annotation. annotation @data inheritance produces next warning: generating equals/hashcode implementation without call superclass, though class not extend java.lang.object. if intentional, add '@equalsandhashcode(callsuper=false)' type. is advisable add annotation @equalsandhashcode (callsuper = true) or @equalsandhashcode (callsuper = false) ? if not added, 1 callsuper=false or callsuper=true ? the default value false . 1 if don't specify , ignore warning. yes, recommended add @equalsandhashcode annotation on @data annotated classes extend else object. cannot tell if need true or false , depends on class hierarchy, , need examined on case-by-case basis. however, project or package, can configure in lombok.config call super methods if not direct subclass of object. lombok.equalsandhashcode.callsuper = call for configuration system ...
