# @sunsama/splash

@sunsama/splash is a NPM Package that holds all the business logic necessary for our Webflow Splash pages. It makes it easy, as a developer, to build the logic for things like generating waitlist records, tracking facebook pixel values, generating amplitude device ids, tracking affiliate page views, and redirecting users to the right page.

The goal of this package is that you should only need to do three things in Webflow:

1. Import `@sunsama/splash` in the `<HEAD>`
2. Initialize the package with the environment with `SunsamaSplash.default.initialize("production`)`once the`DOMContentLoaded` event happens via the footer.
3. Set the correct id or data-tag on critical elements in Webflow.

If you do that, all the business logic should just work.

The project also contains `webflow-simulator` which is a barebones Express app meant to simulate our Webflow pages. It allows you to test your changes to `@sunsama/splash` against a real UI on localhost. It's a bit of extra work to maintain this and keep it "in sync" with our Webflow pages but it's helpful because it simplifies local development.

## Webflow Requirements

### Email Capture Form

If you want to display an element that takes an email, creates a lead (waitlist record), and then forwards the user to the app page:

The email capture form should be a `<form>` block and follow these rules:

-   The `id` of the email `<input>` must be `email`
-   The class of the `<form>` must be `email-form`

### Signup from App Button

If you want a button that takes the user to app.sunsama.com/signup:

-   The button needs `data-trigger-signupbutton`

### Trial Length Display

In some cases, we want to display a non-standard trial length.

If a CMS Collection page wants to offer a special trial length it needs this custom code in it's custom code "Before `<body>` tag section":
`<script> window.pageTrialLength = {{wf {&quot;path&quot;:&quot;trial-length&quot;,&quot;type&quot;:&quot;Number&quot;\} }}; // This weird stuff is the CMS Collection Item </script>`
When a PartnerStack key is detected, we give a 30 day trial. In order for text like "14-day" to be replaced with "30-day" make sure to set the attribute `data-trial-text = ""`

### User Referral Name Display

On some pages, we want to show a banner with the name of the user (not affiliate/ambassador) who referred you.

We do this with the `data-refferal-name` attribute being set on text element that has the word `someone` in it. When the page loads, we replace `someone` with their name, if the tag is present.

### Blog pages

The Blog Newsletter sign up button must have the class `blog-post_subscribe-button`

### Conversion Pages

In Webflow, the set of pages under `/conversion` are used to fire Google analytics events from "in-app" events. For example, when a user starts a trial inside of app.sunsama.com, we render a hidden `<iframe>` that loads these conversion pages where the Google analytics code runs. See: https://github.com/sunsama/sunsama/pull/5154

### Warnings

1. When duplicating elements into new pages in Webflow, you might get things like `name-2` in the `id`, so be careful here.

### AB Testing

This library will automatically show different versions of a page and log the version to Amplitude for AB Testing. Here's how it works:

1. In Webflow, create multiple copies of an element you want to test e.g. a Headline
2. Wrap that element in a `<div>`
3. Navigate to the Attributes and set them like so:
    - `data-experiment=${experimentName}`
    - `data-variant=${A|B}` // Currently only support A or B
    - `data-bias` // Number between 0 - 1 that controls how often A is shown relative to B e.g. 0.9 would show A 9 times out of 10, this must be set on the A variant. Defaults to 0.5
    - `hidden="true"` // This is optional and for your sanity in Webflow, you might make your A variant not hidden and your B variant hidden so you don't see duplicated items in the Webflow editor.
4. When the page loads, the library will automatically unhide/hide the relevant variants and set an Amplitude User Property like `{ [`Experiment ${experiment} Variant Group`]: desiredVariant }` that you can use to segment events/funnels on.

## Local Development

From the root of the repo bring up the basic web app service:

```
make install
make start-lite
```

Then bring up the "development" environment here

```
cd library/splash
npm install
npm start
```

This exposes an extremely basic HTML page at `localhost:3010/` that has two text fields and a button that match the webflow pages. The page has the built script bundle imported in it's head and a single call to initialize it `SunsamaSplash.default.initialize("development");` after the body. The goal is that we can do the same thing in Webflow and simply change code here.

## Testing

Run `npm test` for running Cypress tests in CLI, or `npm run test/dev` for the UI.

## Publishing

1. Update the Package Version
2. Publish to NPM `npm publish`
3. Increment the Version in Webflow: https://webflow.com/dashboard/sites/sunsama-new/code and save changes
4. Republish the Webflow Page
