typescript在react中的使用

声明state和props

常见通用声明

public state: {
    collapsed: boolean
};
  
static defaultProps = {
    collapsed: boolean
};
    
readonly state = {
    collapsed: boolean
    // ...
}; 

d.ts文件声明

export interface ISiderMenuProps {
    logo?: string,
    // ...
}

export interface ISiderMenuState {
    collapsed: boolean,
    // ...
}

class SiderMenu extends PureComponent<ISiderMenuProps, ISiderMenuState>
