javascript - Display images on ReactJS -


i'm building app display images on react page. images have been uploaded onto local folder. coupled react app nodejs server , mongodb.

i want display img saved in folder. i've been trying use path of file don't think works img tag.

could clarify on that? 

class showallphotos extends component {    constructor(props) {     super(props)      this.state = {       library: []     }   }    componentdidmount() {     axios.get('/all')     .then((response) => {       let arr = response.data;       console.log('arr', arr);       this.setstate({         library: arr       });       console.log("response data", arr);       console.log('library worked', response.status); // ex: 200     })     .catch(function (error) {       console.log(error);       console.log('error getting library', error.status);     });    }    render() {        let renderlibrary = () => {         return(           <div>             {this.state.library.map(function(library) {               return(                 <div classname="row" >                   <div classname="col-xs-6 col-md-6" id='card'>                     <img src={library.path} alt='some text'/>                   </div>                 </div>               );             })}           </div>         )       }      return (       <div classname="container">         <div>         {renderlibrary()}         </div>       </div>     );   } }  export default showallphotos;

and here's route backend - checked on postmate , it's ok.

var express = require('express'); var router = express.router();  var photo = require('../model/photo');  router.get('/', function(req, res, next){   photo.find({}, function(err, photos){     if(err){       res.json({error:err});     }     res.json(photos);   }); });  module.exports = router;

you need require image use in img tag. use -

<img src={require(library.path)} />

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 ...
