Typescript Interface

Description

The TypeScript type declarations for danmaku are very comprehensive, so when you use it in TypeScript, you will get excellent type hints. This is very friendly for a plugin-based system and can even be considered indispensable.

Declare Danmaku Content Type

When you get the danmaku instance type in various hooks, the type of its content defaults to unknown. However, you can pass a generic type during initialization to constrain it.

import { create } from 'danmu';

const manager = create<{ content: string; img: string }>({
  $beforeMove(danmaku) {
    // You can see that the `data` type is `{ content: string, img: string }`
    danmaku.data;
  },
});

Pass a type to statuses

Since manager.statuses does not perform any work within the kernel, it simply provides a plain object for users to record states. Therefore, its default type is Record<PropertyKey, unknown>. You can also pass a generic type to change it. For a specific example, refer to our demo.

import { create } from 'danmu';

const manager = create<string, { background: string }>();

// You can see that the `statuses` type is `{ background: string }`
manager.statuses;
