1. create tslint.json tsconfig.json rn-cli.config.js
tslint.json
{

"rules": {
// override tslint-react rules here

rn-cli.config.js
module.exports = {
getTransformModulePath() {
return require.resolve('react-native-typescript-transformer')
},
getSourceExts() {
return ['ts', 'tsx', 'js']
}
}
2. install tslint tslint-react,@types/react, react-native-typescript-transformer,此处可能需要升级node到10
yarn add tslint tslint-react react-native-typescript-transformer --dev
yarn add @types/react
3.添加全局检测命令
"tslint": "tslint -c tslint.json 'src/**/*.{ts,tsx}'"
4.设置props
export interface ButtonProps {
text: string,
callback: () => any
}
export default class RNButton extends PureComponent {
5.设置defaultProps
static defaultProps = {
duration: 2000
}
