this tiny library helps us (OpenReplay folks) to create proxy objects for fetch, XHR and beacons for proper request tracking in @openreplay/tracker and Spot extension.
example usage:
import createNetworkProxy from '@openreplay/network-proxy';
const context = this;
const ignoreHeaders = ['Authorization'];
const tokenUrlMatcher = /\/auth\/token/;
function setSessionTokenHeader(setRequestHeader: (name: string, value: string) => void) {
const header = 'X-Session-Token
const sessionToken = getToken() // for exmaple, => `session #123123`;
if (sessionToken) {
setRequestHeader(header, sessionToken)
}
}
function sanitize(reqResInfo) {
if (reqResInfo.request) {
delete reqResInfo.request.body
}
return reqResInfo
}
const onMsg = (networkReq) => console.log(networkReq)
const isIgnoredUrl = (url) => url.includes('google.com')
// Gets current tracker request’s url and returns boolean. If present,
// sessionTokenHeader will only be applied when this function returns true.
// Default: undefined
const tokenUrlMatcher = (url) => url.includes('google.com');
// this will observe global network requests
createNetworkProxy(
context,
options.ignoreHeaders,
setSessionTokenHeader,
sanitize,
(message) => app.send(message),
(url) => app.isServiceURL(url),
options.tokenUrlMatcher,
)
// to stop it, you can save this.fetch/other apis before appliying the proxy
// and then restore them
