This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official pluginimport DrawingBoard from '@/drawingBoard'

class Eraser { // 声明一个board变量，用于存储画板 board: DrawingBoard

// 构造函数，传入一个画板
constructor(board: DrawingBoard) {
	// 将传入的画板赋值给board变量
	this.board = board
}

——cleanLine(){
	// 计算 cleanedWidth 的长度
	const asin = cleanWidth * Math.sin(Math.atan((y2 - y1) / (x2 - x1)))
	const acos = cleanWidth * Math.cos(Math.atan((y2 - y1) / (x2 - x1)))
	// 计算 cleanedWidth 的四个点的坐标
	const x3 = x1 + asin
	const y3 = y1 - acos
	const x4 = x1 - asin
	const y4 = y1 + acos
	const x5 = x2 + asin
	const y5 = y2 - acos
	const x6 = x2 - asin
	const y6 = y2 + acos
}

}SLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

• Configure the top-level parserOptions property like this:

   parserOptions: {
    ecmaVersion: 'latest',
    sourceType: 'module',
    project: ['./tsconfig.json', './tsconfig.node.json'],
    tsconfigRootDir: __dirname,
   },

• Replace plugin:@typescript-eslint/recommended to plugin:@typescript-eslint/recommended-type-checked or plugin:@typescript-eslint/strict-type-checked
• Optionally add plugin:@typescript-eslint/stylistic-type-checked
• Install eslint-plugin-react and add plugin:react/recommended & plugin:react/jsx-runtime to the extends list
