javascript - How to import an entire folder of SVG images (or how to load them dynamically) into a React Web App? -


i have component takes in :itemname , spits out html bundle containing image. image different each bundle.

here's have:

import react, { component } 'react'; import { navlink } 'react-router-dom';  import svginline "react-svg-inline";  export default (props) => (   <navlink classname="hex" activeclassname="active" to={'/hex/' + props.itemname}> {react.createelement(svginline, {svg: props.itemname})} </navlink> )

how make component work?

i know if imported images explicitly, call images so...

import svginline "react-svg-inline"; import sasssvg "./images/sass.svg";  <navlink classname="hex" activeclassname="active" to="/hex/sass"><svginline svg={ sasssvg } /></navlink>

this work, since need include ~60 svgs, adds lot of excess code.

also, found in question code...

import * iconid './icons';

but doesn't seem work (it part of question, not answer), , answer bit nonspecific answer question i'm asking.

i found this question again there's answer (although unapproved) possess more questions answers. so, after installing react-svg, set test see if answer works so...

import react, { component } 'react'; import reactdom 'react-dom' import { navlink } 'react-router-dom'; import reactsvg 'react-svg'  export default (props) => (   <navlink classname="hex" activeclassname="active" to={'/hex/' + props.itemname}>     <reactsvg       path={"images/" + props.itemname + ".svg"}       callback={svg => console.log(svg)}       classname="example"     />   </navlink> )

but, op of question asking, page can't find svg after copying entire image folder build folder. i've tried "./images/"

i feel i'm missing 1 last key piece of information , after searching past day, hoping identify piece i'm missing.

if using react, suspect using webpack. can use require.context instead of es6 import , webpack resolve when building.

this first line import. grab files ending in .svg images folder. change 2nd parameter false if don't want recursive folder scanning.

const svgs = require.context('./images', true, /\.svg$/)

this gives function keys property , id property. can pass filepath function image. keys property gives list of valid filepaths. id property webpack module id. might easier see in example: survivejs webpack dynamic loading

this api limited , perhaps unintuitive, want convert data structure. here 3 examples might useful.

create array of files. can grab index number keys array if need access image pathname.

const svgs = require.context('./images', true, /\.svg$/) const keys = svgs.keys()  const svgsarray = keys.map(key => svgs(key))

create array of objects, each object being {path, file} 1 image

const svgs = require.context('./images', true, /\.svg$/)  const svgsobjarray = svgs.keys()   .map(key => {     path: key,     file: svg(key),   })

create object pathname key matching file.

const svgs = require.context('./images', true, /\.svg$/)  const svgsobj = svg.keys   .map(key => [key, svgs(key) )   .reduce(images, img => {     images[img[0]] = img[1]     return images   }, {})

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
