CSAI Manager
===

Simple class to conduct and manage the relation between content playback and an ad experience applied on top - client side.

Installation

npm install @eyevinn/csai-manager

Basic Usage

``js
const videoElement = document.querySelector("video");
new CSAIManager({
contentVideoElement: videoElement,
adBreakVASTList: [
{
timeOffset: 0,
vastUrl:
"https://eyevinn.adtest.eyevinn.technology/api/v1/vast?dur=30",
},
],
});

videoElement.addEventListener("ended", () => {
csaiManager.destroy();
});
`

If you do not send in an already created ad video element (through the available option listed below), but let the library create the element, you will need to set the container to position: relative; as the CSAI Manager will try to position the new element absolute edge to edge of the container.

`ts
export interface ICSAIManagerOptions {
debug?: boolean;

contentVideoElement: HTMLVideoElement;
autoManagePlayback?: boolean; // default true; whether you want the manager to pause/play the content, or if you want to act on the events
isLive?: boolean; // default false; will adjust the validation to not require vast or vmap url etc
autoplay?: boolean; // default false

// Whether you have created a video element for the ads on beforehand, or would want to render it in a div. As fallback it finds the parent of the contentVideoElement
container?: HTMLElement;
adVideoElement?: HTMLVideoElement;

// For fetching ads - either provide a vmap url, or a list of time offsets and vast url's
vmapUrl?: string;
adBreakVASTList?: IAdBreakVASTItem[];
}

export interface IAdBreakVASTItem {
timeOffset: number;
vastUrl: string;
}
`

You may listen to events exposed by the ad manager, to for instance handle the pause and play of your content yourself.

`js
const videoElement = document.querySelector("video");
const csaiManager = new CSAIManager({
contentVideoElement: videoElement,
adBreakVASTList: [
{
timeOffset: 0,
vastUrl:
"https://eyevinn.adtest.eyevinn.technology/api/v1/vast?dur=30",
},
],
});

csaiManager.on("*", (event, data) => {

console.log("DEBUG EVENT", event, data);

if (event === "breakStart") {
videoElement.pause();
}
if (event === "breakEnd") {
videoElement.play();
}
});
`

The events exposed are matching the VAST tracking - i.e. IAB events

`ts
export enum AdTrackingEvent {
START = "start",
IMPRESSION = "impression",
EXPAND = "expand",
MUTE = "mute",
UNMUTE = "unmute",
PAUSE = "pause",
RESUME = "resume",
REWIND = "rewind",
CLOSE = "close",
COMPLETE = "complete",

FIRST_QUARTILE = "firstQuartile",
MIDPOINT = "midpoint",
THIRD_QUARTILE = "thirdQuartile",

CLICK_THROUGH = "clickThrough",

ERROR = "error",
}

export enum AdBreakTrackingEvent {
BREAK_START = "breakStart",
BREAK_END = "breakEnd",
}
`

- play() to trigger play when autoplay isn't set to true

These methods are specifically to be used for live
(remember to set the initOption autoManagePlayback to false to not pause the live stream)

- fetchAdBreak(vastUrl: string): Promise
- triggerAdBreak(): Promise`
