This plugin allows you to capture Pinia mutations/state and inspect them later on while replaying session recordings. This is very useful for understanding and fixing issues.

npm i @openreplay/tracker-vuex

Initialize the @openreplay/tracker package as usual and load the plugin into it. Call the plugin and to set up the store name, this will return a named store tracker instance which you can call with your store exemplar as an argument to enable tracking of this store.

If your website is a Single Page Application (SPA)

import OpenReplay from '@openreplay/tracker';
import trackerVuex from '@openreplay/tracker-vuex';

If your web app is Server-Side-Rendered (SSR)

Section titled If your web app is Server-Side-Rendered (SSR)
import OpenReplay from '@openreplay/tracker/cjs';
import trackerVuex from '@openreplay/tracker-vuex/cjs';

const tracker = new OpenReplay({
  projectKey: PROJECT_KEY
  // ... options

// ...

const examplePiniaStore = useExamplePiniaStore()
const vuexPlugin = tracker.use(trackerVuex(<options>)) // check list of available options below

const piniaStorePlugin = vuexPlugin('STORE NAME') // add a name to your store, 
                                                  // optional (will be randomly generated otherwise)
piniaStorePlugin(examplePiniaStore) // start tracking state updates

// now you can use examplePiniaStore as usual pinia store (destructure values or return it as a whole etc)

You can customize the plugin behavior with options to sanitize your data. They are similar to the ones from the standard createLogger plugin.

  filter (mutation, state) {
    // returns `true` if a mutation should be logged
    // `mutation` is a `{ type, payload }`
    return mutation.type !== "aBlacklistedMutation";
  transformer (state) {
    // transforms the state before logging it.
    // for example return only a specific sub-tree
    return state.subTree;
  mutationTransformer (mutation) {
    // mutations are logged in the format of `{ type, payload }`
    // we can format it any way we want.
    return mutation.type;
