The `data-ghost` attribute expects the URL for your Ghost site, which is the only input Portal needs to work with your site's membership data via Ghost APIs.
Its possible to add custom trigger button of your own by adding data attribute `data-portal` to any HTML tag on page, and also specify a specific [page](https://github.com/TryGhost/Ghost/blob/main/ghost/portal/src/pages.js#L13-L22) to open from it by using it as `data-portal=signup`.
The script also adds custom class names to this element for open and close state of popup - `gh-portal-open` and `gh-portal-close`, allowing devs to update its UI based on popup state.
Alternatively, use `yarn dev --all` to load Portal and other supported apps/services, see [dev.js](https://github.com/TryGhost/Ghost/blob/main/.github/scripts/dev.js) for more information.
Portal is primarily tested via Ghost's e2e browser tests. In order to test against your local changes rather than the last published package on npm you need to have the local portal build being served and to configure Ghost to use the local URL.
1. Run `yarn dev` in `ghost/apps/portal` to serve the local portal build on http://localhost:4175/portal.min.js
2. Run the Ghost e2e tests in `ghost/core`, providing an ENV variable to override the portal URL:
A patch release can be rolled out instantly in production, whereas a minor/major release requires the Ghost monorepo to be updated and released. In either case, you need sufficient permissions to release `@tryghost` packages on NPM.
If you're releasing new code that should not immediately go live _always_ use a minor or major version when publishing.
In order to have Ghost's e2e tests run against the new code on CI or to test the new code in staging, you need to publish to npm following the Minor / major release process below.
1. Run `yarn ship` and select a patch version when prompted
2. (Optional) Clear JsDelivr cache to get the new version out instantly ([docs](https://www.notion.so/ghost/How-to-clear-jsDelivr-CDN-cache-2930bdbac02946eca07ac23ab3199bfa?pvs=4)). Typically, you'll need to open `https://purge.jsdelivr.net/ghost/portal@~${PORTAL_VERSION}/umd/portal.min.js` and
`https://purge.jsdelivr.net/ghost/portal@~${PORTAL_VERSION}/umd/main.css` in your browser, where `PORTAL_VERSION` is the latest minor version in `ghost/core/core/shared/config/defaults.json` ([code](https://github.com/TryGhost/Ghost/blob/0aef3d3beeebcd79a4bfd3ad27e0ac67554b5744/ghost/core/core/shared/config/defaults.json#L185))
1. Run `yarn ship` and select a minor or major version when prompted
2. Update the Portal version in `ghost/core/core/shared/config/defaults.json` to the new minor or major version ([code](https://github.com/TryGhost/Ghost/blob/0aef3d3beeebcd79a4bfd3ad27e0ac67554b5744/ghost/core/core/shared/config/defaults.json#L198))
