The target websocket watch the specific url instead of upstream(host) with path #303
Description
Prerequisites
- I have written a descriptive issue title
- I have searched existing issues to ensure the feature has not already been requested
🚀 Feature Proposal
Ability to customize the url for websockets, currently it is not possible.
Best regards, Anton.
Motivation
I use fastify-http-proxy for development, When I run project then the proxy is look at some server, for example: test, stage, feature.
Example:
I have server with backend api url like this https://api-test.myserver.com, and websocket url like this https://websocket.myserver.com/conection.
My local frontend looks at the proxy, and the proxy looks at backend api url. It working is well but when I turn on the websocket: true property then proxy trying to conect to wss://api-test.myserver.com and the url for sockets cannot be configured.
I ask to make it possible to configure the url for the websockets. Or can I suggest a solution with the pull request.
Example
Basically the solution is simple. Need add new property to proxy options, like wsUpstream.
This code
if (options.upstream !== '') {
wsProxy.addUpstream(fastify.prefix, rewritePrefix, options.upstream, options.wsClientOptions)
// The else block is validate earlier in the code
}
Replace with
if (isDefinedString(options.wsUpstream) || isDefinedString(options.upstream)) {
wsProxy.addUpstream(
fastify.prefix,
rewritePrefix,
options.wsUpstream ? options.wsUpstream : options.upstream,
options.wsClientOptions,
)
// The else block is validate earlier in the code
}
Helper function
function isDefinedString (string) {
return typeof string === 'string' && !!string
}
