@openreplay/tracker-fetch
Advanced tools
This plugin allows you to capture fetch
payloads and inspect them later on while replaying session recordings. This is very useful for understanding and fixing issues.
npm i @openreplay/tracker-fetch
Use the provided fetch
method from the plugin instead of the one built-in.
import tracker from '@openreplay/tracker';
import trackerFetch from '@openreplay/tracker-fetch';
const tracker = new OpenReplay({
projectKey: PROJECT_KEY
});
const fetch = tracker.use(trackerFetch(options)); // check list of available options below
tracker.start();
fetch('https://myapi.com/').then(response => console.log(response.json()));
Follow the below example if your app is SSR. Ensure tracker.start()
is called once the app is started (in useEffect
or componentDidMount
).
import OpenReplay from '@openreplay/tracker/cjs';
import trackerFetch from '@openreplay/tracker-fetch/cjs';
const tracker = new OpenReplay({
projectKey: PROJECT_KEY
});
const fetch = tracker.use(trackerFetch(options)); // check list of available options below
//...
function MyApp() {
useEffect(() => { // use componentDidMount in case of React Class Component
tracker.start();
fetch('https://myapi.com/').then(response => console.log(response.json()));
}, [])
//...
}
trackerFetch({
overrideGlobal: boolean;
failuresOnly: boolean;
sessionTokenHeader: string;
ignoreHeaders: Array<string> | boolean;
sanitiser: (RequestResponseData) => RequestResponseData | null;
})
overrideGlobal
: Overrides the default window.fetch
. Default: false
.failuresOnly
: Captures requests having 4xx-5xx HTTP status code. Default: false
.sessionTokenHeader
: In case you have enabled some of our backend integrations (i.e. Sentry), you can use this option to specify the header name (i.e. 'X-OpenReplay-SessionToken'). This latter gets appended automatically to each fetch request to contain the OpenReplay sessionToken's value. Default: undefined
.ignoreHeaders
: Helps define a list of headers you don't wish to capture. Set its value to false
to capture all of them (true
if none). Default: ['Cookie', 'Set-Cookie', 'Authorization']
so sensitive headers won't be captured.sanitiser
: Sanitise sensitive data from fetch request/response or ignore request comletely. You can redact fields on the request object by modifying then returning it from the function:interface RequestData {
body: BodyInit | null | undefined; // whatewer you've put in the init.body in fetch(url, init)
headers: Record<string, string>;
}
interface ResponseData {
body: string | Object | null; // Object if response is of JSON type
headers: Record<string, string>;
}
interface RequestResponseData {
readonly status: number;
readonly method: string;
url: string;
request: RequestData;
response: ResponseData;
}
sanitiser: (data: RequestResponseData) => { // sanitise the body or headers
if (data.url === "/auth") {
data.request.body = null
}
if (data.request.headers['x-auth-token']) { // can also use ignoreHeaders option instead
data.request.headers['x-auth-token'] = 'SANITISED';
}
// Sanitise response
if (data.status < 400 && data.response.body.token) {
data.response.body.token = "<TOKEN>"
}
return data
}
// OR
sanitiser: data => { // ignore requests that start with /secure
if (data.url.startsWith("/secure")) {
return null
}
return data
}
// OR
sanitiser: data => { // sanitise request url: replace all numbers
data.url = data.url.replace(/\d/g, "*")
return data
}
