API endpoint routes can now be configured individually, so you can rename /track, /engage, and /groups HTTP endpoints arbitrarily. Configure with the api_routes option:
mixpanel.init(`my token`, {
api_host: `https://my-proxy.example.com`,
api_routes: {
track: `foo/`,
engage: `bar/`,
groups: `baz/`,
},
));In the above example, event-tracking requests will go to https://my-proxy.example.com/foo/, user profile updates to https://my-proxy.example.com/bar/, etc.
Other fixes:
- Event properties object passed to
mixpanel.track()will no longer be mutated - Super properties are now reloaded from persistence when making every tracking call (i.e., kept fresh when another tab/window in the same browser has updated them)
- Extra failsafe behavior for trying to clear queued requests when localStorage doesn't work on startup, e.g., when localStorage is full so writes fail
- Block Chrome-Lighthouse user agent
- Fix for error in
add_group()when adding a new group to an existing list
