  return true;
});

Support

Global Placeholder `'{{__adv_channels_adapter__}}'`

support dynamic import from cocos source code, just like:

// source code
window.advChannels = "{{__adv_channels_adapter__}}"; // 防止 rollup 打包进行 tree-shaking 省略掉该代码（ dead code ），占位符变量可挂载在全局

// 在 Facebook 渠道下代码会被替换为
window.advChannels = "Facebook";

Config

`exportChannels`

export package from target platforms

const exportChannels: TChannel[] = ['Facebook', 'Google']

`injectOptions`

inject script in building html

type TChannel =
  | "AppLovin"
  | "Facebook"
  | "Google"
  | "IronSource"
  | "Liftoff"
  | "Mintegral"
  | "Moloco"
  | "Pangle"
  | "Rubeex"
  | "Tiktok"
  | "Unity";

const injectOptions: {
  [key in TChannel]: {
    head: string; // 在 html 的 head 标签内尾部追加
    body: string; // 在 html 的 body 标签内，且在所有 script 前追加
    sdkScript: string; // 在渠道对应地方注入 sdk 脚本
  };
} = {};

Tinify

let config = {
  tinify: true, // compress resource before build package
  tinifyApiKey: '', // tinify api key, visit to https://tinypng.com/developers
}
