=== Considerations for basePath
All communication from the Kibana UI to the server needs to respect the
`server.basePath`. Here are the "blessed" strategies for dealing with this
based on the context:
[float]
==== `<img>` and `<a>` elements
Write the `src` or `href` urls as you would without the base path, but then
replace `src` or `href` with `kbn-src` or `kbn-href`.
["source","shell"]
-----------
<img kbn-src="plugins/kibana/images/logo.png">
-----------
[float]
==== Getting a static asset url
Use webpack to import the asset into the build. This will give you a URL in
JavaScript and gives webpack a chance to perform optimizations and
cache-busting.
["source","shell"]
-----------
// in plugin/public/main.js
import uiChrome from 'ui/chrome';
import logoUrl from 'plugins/facechimp/assets/banner.png';
uiChrome.setBrand({
logo: `url(${logoUrl}) center no-repeat`
});
-----------
[float]
==== API requests from the front-end
Use `chrome.addBasePath()` to append the basePath to the front of the url.
["source","shell"]
-----------
import chrome from 'ui/chrome';
$http.get(chrome.addBasePath('/api/plugin/things'));
-----------
[float]
==== Server side
Append `config.get('server.basePath')` to any absolute URL path.
["source","shell"]
-----------
const basePath = server.config().get('server.basePath');
server.route({
path: '/redirect',
handler(req, reply) {
reply.redirect(`${basePath}/otherLocation`);
}
});
-----------
[float]
==== BasePathProxy in dev mode
The Kibana dev server automatically runs behind a proxy with a random
`server.basePath`. This way developers will be constantly verifying that their
code works with basePath, while they write it.
To accomplish this the `serve` task does a few things:
1. change the port for the server to the `dev.basePathProxyTarget` setting (default `5603`)
2. start a `BasePathProxy` at `server.port`
- picks a random 3-letter value for `randomBasePath`
- redirects from `/` to `/{randomBasePath}`
- redirects from `/{any}/app/{appName}` to `/{randomBasePath}/app/{appName}` so that refreshes should work
- proxies all requests starting with `/{randomBasePath}/` to the Kibana server
This proxy can sometimes have unintended side effects in development, so when
needed you can opt out by passing the `--no-base-path` flag to the `serve` task
or `npm start`.
["source","shell"]
-----------
npm start -- --no-base-path
