# promoted-snowplow-logger

This event logger (tracker) library is used to simplify browser-side logging.  It relies on the browser-side JS having the Snowplow tracker library installed.  This library uses the Promoted Metrics Snowplow-compatible API.  See the [web integration guide](https://docs.promoted.ai/docs/how-to-your-web-events-with-promoted-metrics) to learn how to use this library.

## Scripts

- Run most commands: `npm run finish`

## When developing locally

If you want to test local changes in an actual deployment, use `npm link`.

1. Run `npm run updateLink`.
4. Go to client directory and run `npm link promoted-snowplow-logger`.

When you update `promoted-snowplow-logger`, run `npm run updateLink`.

When you want to undo, use `npm unlink` in `promoted-snowplow-logger/dist` and `npm unlink promoted-snowplow-logger` in the client directory.

## Deploy

We use a GitHub action that runs semantic-release to determine how to update versions.  Just do a normal code review and this should work.  Depending on the message prefixes (e.g. `feat: `, `fix: `, `clean: `, `docs: `), it'll update the version appropriately.
