Installation
We currently offer two ways to install the library.
CDN
Add the following line to the <head> tag of your HTML document:
<script src="https://cdn.croct.io/js/v1/lib/engine.js"></script>This guarantees the application will always use the latest version of the library.
NPM
NPM is the recommended installation method when building large scale applications with Croct. It pairs nicely with module bundlers such as Webpack or Browserify and includes Typescript typings.
Run the following command to install the latest version of the package:
npm install @croct/rule-engineBasic usage
The following example shows how to define a rule to display a alert to returning users only:
import croct from '@croct/plug';
import {RuleEngine, Definitions, Action, actions, audiences} from '@croct/rule-engine';
export class WelcomeUser implements Action {
public apply(): void {
window.alert('Welcome back!');
}
}
const definitions: Definitions = {
extensions: [
actions({
'welcome-user': new WelcomeUser(),
}),
audiences({
'returning-users': 'user is returning',
}),
],
pages: {
'/home': [
{
rules: [
{
name: 'welcome-returning-users',
properties: {
audience: 'returning-users',
action: 'welcome-user',
},
},
],
},
],
},
};
croct.plug({appId: '<APP_ID>'});
const engine = new RuleEngine(croct.sdk, definitions);
engine.run();Don't forget replacing <APP_ID> with the public application ID.
