ReactJS, import files within render() -


i need import files (pdfs in case, svgs later) <embed> element. iterating on list of props send me path pdf. when imported @ head of component, , injected works fine expected. however, need dynamically set these paths, , know cannot import inside render. using paths gives me no result.

does not work:

// pdf.src = './path/to/file.pdf' {project.projectpdfs.map((pdf, index) =>     <embed classname="pdf-viewer" src={pdf.src} width="100%" key={index} />     ) }

works:

import pdf './path/to/file.pdf'; {project.projectpdfs.map((pdf, index) =>     <embed classname="pdf-viewer" src={pdf} width="100%" key={index} />     ) }

app bootstrapped create-react-app have url-loader, not sure else going on under hood.

create-react-app using webpack build app. url of file changed after built.

import pdf './path/to/file.pdf'; change file path hashed string , stored pdf. have no error in second way.

in case, have 2 ways do:

  1. import resources first

    import pdf1 '/path/to/pdf1'; import pdf2 '/path/to/pdf2'; import pdf3 '/path/to/pdf3'; import pdf4 '/path/to/pdf4'; const pdfs = {pdf1, pdf2, pdf3, pdf4}; ... {project.projectpdfs.map((pdf, index) => (     <embed classname="pdf-viewer" src={pdfs[pdf]} width="100%" key={index} /> )}

  2. dynamic import

    const embeds = await promise.all(project.projectpdfs.map(async (pdf, index) => {     const pdfpath = await import(pdf);     return (<embed classname="pdf-viewer" src={pdfpath} width="100%" key={index} />); }));

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 ...
