javascript - Making Browserify bundle play nice with ReactDevTools -


react 0.13.3

i started using browserify organize frontend react code. i'm using react developer tools chrome extension debugging. however, i'm having trouble simple react code.

var react = require('react/addons');  //react dev-tools requires react on global scope. scope hidden when bundling window.react = react;  var app = react.createclass({     render: function(){         return (             <div>                <p>hello world</p> <!-- renders fine -->             </div>         )     } });  react.render(     <app />,     document.getelementbyid('content') );

the following code works, , "hello world" renders fine. trouble starts when start react debugger in console. expect following:

<top level>     <app>...</app> </top level>

but instead, says:

<top level></top level>

how can <app> rendered without react devtools recognizing them?

it seems enough people have stumbled upon matter, , official guide not mention particular symptom. after gathering enough evidence, best answer posted here, if there might other causes <top level></top level> issue.

the react devtools may not work if there more 1 instance of react in bundle. related incorrect bundling tool configuration (browserify or webpack) in particular component. react components (and other libraries supported react, such mixins) should have react peerdependency in npm , "external" in browserify/webpack. make distributable version of module not embed react itself. in addition, if react add-ons used, "react/addons" may have registered external dependency.

in cases not followed, mere inclusion of module require (or es6's import) render dev tools useless. when instance of react emerges, 1 register source of element tree, why empty element shown. have tracked down bug in react-loaders (issue #2), , it's fixed since 1.2.3. same might have happened react-google-maps according @carpetfizz said, although have not looked case.

one easy trick debug take barebones module + web page , iteratively add require instructions until react dev tools stop working. once faulty component found, file issue.

var react = require('react'); var loader = require('react-loaders'); // testing react-loaders  var app = react.createclass({     render: function(){         return (             <div>                <p>check react tab!</p>             </div>         )     } });  react.render(<app />, document.getelementbyid('container'));

another peculiar solution carried out in react packages meteor, development runtime changed load main instance of react last (commit).

this topic lifted in issue #90, helped identify more cases of non-compliant packages.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
