Customize Events

Sometimes you may want to customize how Logspot tracks events. You can achieve that by using the event mapper.

You can pass a callback function which will be executed before sending the event to the API.

import Logspot from "@logspot/web";

const annonymizeHostname = (hostname) => ...;

Logspot.init({ ...,
    eventMapper: (payload) => {
        return {
            ...payload,
            hostname: annonymizeHostname(payload.hostname)
        };
    }
});

eventMapper callback can be asynchronous e.g.:

import Logspot from "@logspot/web";

const annonymizeHostname = async (hostname) => ...;

Logspot.init({ ...,
    eventMapper: async (payload) => {
        return {
            ...payload,
            hostname: await annonymizeHostname(payload.hostname)
        };
    }
});

Event payload

type EventPayload = {
  name: string;
  message?: string | null;
  notify?: boolean | null;
  user_id?: string;
  metadata?: any | null;
  hostname?: string | null;
  url?: string | null;
  referrer?: string | null;
  language?: string | null;
  screen?: string | null;
};

Limitations

There are two requirements:

• name is a required field
• screen needs to be in format numberxnumber e.g. 1240x1200

location, browser and os cannot be overriden yet.
