react router - Routing Issue In ReactJs -


i beginner in reactjs. trying create multipage app, i'm facing issues related routing.

enter image description here

this code:

import react 'react'; import reactdom 'react-dom'; import { router, route} 'react-router';  ......  reactdom.render((     <router>         <route path="/" component={my}>             <route path="home" component={home}>                <route path="contact" component={contact}/>                <route path="about" component={about}/>             </route>         </route>      </router> ), document.getelementbyid('root'))

it seems react router expecting history prop haven't provided. here example router v4 doesn't support route nesting in question example.

import react 'react' import reactdom 'react-dom' import { browserrouter, route, switch } 'react-router-dom'    reactdom.render((     <browserrouter>       <div classname='app'>         <div classname='page'>           <switch>               <route exact path="/" component={1} />               <route path="/second-page" component={2} />               <route path="/third-page" component={3} />               <route component={errorpage} />           </switch>         </div>       </div>   </browserrouter> ), document.getelementbyid('root'))

this 1 route components per respective paths, or return errorpage component if no routes matched.

edit: history prop useless , ignored in browserhistory, purpose of browserhistory create browserhistory.

from source code : 

warning(      !this.props.history,      '<browserrouter> ignores history prop. use custom history, ' +      'use `import { router }` instead of `import { browserrouter router }`.' )

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
