Warning

Zalvena is currently under a rewrite

Zalvena

Fork of the JavaScript SDK for Aptabase, modified for SudoVanilla projects.

Install

Install the SDK using bun or your preferred JavaScript package manager:

bun add @sudovanilla/zalvena

Usage

First you need to get your App Key from Zalvena, you can find it in the Instructions menu on the left side menu.

Initialize the SDK using your App Key:

import { init } from '@sudovanilla/zalvena';
init('<APPKEY>');

// If you selfhost, use this instead
init('<APPKEY', { host: 'https://zv.example.org' });

The init function also supports an optional second parameter, which is an object with the appVersion property.

It's up to you to decide how to get the version of your app, but it's generally recommended to use your bundler (like Webpack, Vite, Rollup, etc.) to inject the values at build time. Alternatively you can also pass it in manually.

Afterwards you can start tracking events with trackEvent:

import { trackEvent } from '@sudovanilla/zalvena';
trackEvent('connect_click');
trackEvent('play_music', {
    name: 'Here comes the sun',
});

A few important notes:

1. The SDK will automatically enhance the event with some useful information, like the OS and other properties.
2. You're in control of what gets sent to Zalvena. This SDK does not automatically track any events, you need to call trackEvent manually.
   • Because of this, it's generally recommended to at least track an event at startup
3. You do not need to await the trackEvent function, it'll run in the background.
4. Only strings and numeric values are allowed on custom properties

Development

To get started, make sure you've already have git and Bun installed.

Then, with Bun, install packages:

bun install

Run test website:
