i have 2 pages. 1 of them dashboard lot of functionality. second page shared dashboard - simple version of first page. dashboard contains view of database (it can contain other info, problem one). can click on filter button , modal window opened. so, simple version of dashboard doesn't have possibility. i'd add it, don't want copy+past code full version of dashboard because code of part 2 thousand lines. i'll add primitive code example: dashboardview = someanotherview.extend({ initialize: function() {...}, events: {...} // huge objects of jquery events, render: function () {...}, ... // 2k lines of functions events }); how can use view on page? tried call function view: dashboardview.prototype.filterclicked(event); but in case event.curenttarget null (it necessary function), tried send "this" context, failed. is there possibility in backbone.js use 1 view 2+ pages without huge copy/past code? ideally if have simple version , full version ...

for example, if have 3 routes in routes.js file compared of 10 routes in same file. file containing 10 routes take longer time load? supposing every route import same size of component. or component imported after we've enter route? the first page load might longer usual (still not noticeable in cases), after that, page entirely cached, resulting in super fast load times, since browser remember everything. wiki

my program being written in swift, class dependency on "no leak skshapenode." class written in obj-c , therefore needs compiler flags used. implemented -fno-objc-arc on skshapenodeleakfree.m file yet compiler still doesn't detect arc disabled. the -fno-objc-arc setting in "compile sources" of target's "build phases" looks fine. it looks must have incorrectly imported .m file in bridging header. should #import .h file in bridging header. explain why you're seeing objective-c arc messages under "swift compiler error" section. wiki

so have multiple folders inside empty idea project , each folder has pom.xml. i need deploy each folder separately gitlab ci recognize main folder empty project. if understand achitecture well, should have separate git repository each of folders in parent idea project. it : /rootproject |- gitrepo1 |- .gitlab-ci.yml |- gitrepo2 |- .gitlab-ci.yml |- gitrepo3 |- .gitlab-ci.yml this way can have separate ci pipelines , deployments each subfolder. there open issue considering possibility change default location of .gitlab-ci.yml file, not yet available : https://gitlab.com/gitlab-org/gitlab-ce/issues/15041 wiki
