!!!Typescript Komponenten .tsx
[ReactJS] kann auch mit Typescript kombiniert werden. Dazu muss in der webpack.config.js folgende Regel für den Babel-Loader konfiguriert werden:
{{{
{
test: /\.(jsx|tsx)$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
options: {
presets: [
"@babel/preset-env",
["@babel/preset-react", {"runtime": "automatic"}],
"@babel/preset-typescript"
]
}
}
}
}}}
Zusätzlich muss in der TS-Config angegeben werden, dass es sich um Extended Javascript handelt:
{{{
{
"compilerOptions": {
"jsx": "react-jsx"
}
}
}}}
!!!Typescript nur Typen generieren

!!!Typescript mit Decorators
Von Typescript sind sehr viele Varianten mit sogenannten Decorators (Annotationen etc.) im Umlauf. Folgende Konfiguration unterstützt einige davon.
webpack.config.js:
{{{
use: {
loader: "babel-loader",
options: {
presets: [
"@babel/preset-env",
"@babel/preset-typescript",
["@babel/preset-react", {runtime: "automatic"}]
],
plugins: [
"@babel/syntax-dynamic-import",
["@babel/plugin-proposal-decorators", {version: "2023-05", decoratorAutoAccessors: true}],
"@babel/plugin-proposal-object-rest-spread",
["@babel/plugin-transform-class-properties"]
]
}
}}}
tsconfig.json:
{{{
{
"compilerOptions": {
"jsx": "react-jsx",
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"target": "ESNext",
"moduleResolution": "node"
}
}
}}}
__Hinweis:__ Viele Konfigurationen sind inkonsistent. Es ist schwierig herauszufinden, welche Kombinationen dieser Plugins mit welchen Parametern zusammen arbeiten.
!!!LitJS Adapter
Folgender Adapter vereinfacht das Einbinden von LitJS-Komponenten:
{{{
import {createComponent} from "@lit/react";
import React from "react";
export function lit(tag) {
return createComponent({
tagName: customElements.getName(tag),
elementClass: tag,
react: React
});
}
export default function Lit({tag, children, ...props}) {
const Element = lit(tag);
return <Element {...props}>{children}</Element>;
}
}}}
Oder in Typescript:
{{{
import {ReactWebComponent, createComponent} from "@lit/react";
import React from "react";
declare var customElements: any;
type Constructor<T> = {
new (): T;
};
type LitProps<I> = {
tag: Constructor<I>,
children: React.ReactNode,
rest: any[]
};
type AnyComponent = (props: any) => React.ReactElement;
export function lit<I extends HTMLElement>(tag: Constructor<I>): ReactWebComponent<I> {
return createComponent({
tagName: customElements.getName(tag),
elementClass: tag,
react: React
});
}
export default function Lit<I extends HTMLElement>({tag, children, ...rest}: LitProps<I>): React.ReactElement {
const Element: AnyComponent = lit(tag) as AnyComponent;
return <Element {...rest}>{children}</Element>;
}
}}}
