我目前正在做一个简单的反应应用程序。
这是我的 index.tsx
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import App from './components/App';
import registerServiceWorker from './registerServiceWorker';
ReactDOM.render(
<App />,
document.getElementById('root') as HTMLElement
);
registerServiceWorker();
这是我的 app.tsx
import * as React from 'react';
import SearchBar from '../containers/price_search_bar';
interface Props {
term: string;
}
class App extends React.Component<Props> {
// tslint:disable-next-line:typedef
constructor(props) {
super(props);
this.state = {term: '' };
}
render() {
return (
<div className="App">
<div className="App-header">
<h2>Welcome to React</h2>
</div>
<p className="App-intro">
this is my application.
</p>
<div>
<form>
<SearchBar term={this.props.term} />
</form>
</div>
</div>
);
}
}
export default App;
还有我的搜索栏容器:
import * as React from 'react';
interface Props {
term: string;
}
// tslint:disable-next-line:no-any
class SearchBar extends React.Component<Props> {
// tslint:disable-next-line:typedef
constructor(props) {
super(props);
this.state = { term: '' };
}
public render() {
return(
<form>
<input
placeholder="search for base budget"
className="form-control"
value={this.props.term}
/>
<span className="input-group-btn" >
<button type="submit" className="btn btn-secondary" >
Submit
</button>
</span>
</form>
);
}
}
export default SearchBar;
最后是 tsconfig.json
:
{
"compilerOptions": {
"outDir": "build/dist",
"module": "esnext",
"target": "es5",
"lib": ["es6", "dom"],
"sourceMap": true,
"allowJs": true,
"jsx": "react",
"moduleResolution": "node",
"rootDir": "src",
"forceConsistentCasingInFileNames": true,
"noImplicitReturns": true,
"noImplicitThis": true,
"noImplicitAny": false,
"strictNullChecks": true,
"suppressImplicitAnyIndexErrors": true,
"typeRoots": [
"node_modules/@types"
],
"noUnusedLocals": true
},
"exclude": [
"node_modules",
"build",
"scripts",
"acceptance-tests",
"webpack",
"jest",
"src/setupTests.ts"
]
}
我不断得到不同的错误后,错误和每当我修复一个错误,另一个出现,我不知道我做了什么,使这样的行为。 这是最新的错误:
./src/index.tsx
(7,3): error TS2322: Type '{}' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<App> & Readonly<{ children?: ReactNode; }> & Reado...'.
Type '{}' is not assignable to type 'Readonly<Props>'.
Property 'term' is missing in type '{}'.
我试图修改我的 tsconfig.json
修复它,但同样的错误仍然出现,我做错了什么,为什么打字机是这样的痛苦。我是非常新的,通过这个例子,我试图了解反应是如何一起工作的。
