Strange React not defined error

I've created the bare minimum solidjs + vite app with just and index.html and index.jsx page:

import { render } from "solid-js/web";

export function App() {
  return <h1>Hello</h1>;
}

render(() => <App/>, document.body);

import { render } from "solid-js/web";

export function App() {
  return <h1>Hello</h1>;
}

render(() => <App/>, document.body);

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8"/>
    <script type="module" src="./index.jsx"></script>
</head>
<body>
</body>
</html>

<!doctype html>
<html lang="en">
<head>
    <meta charset="utf-8"/>
    <script type="module" src="./index.jsx"></script>
</head>
<body>
</body>
</html>

Yet I get this super weird error in the console for the line render(() => <App/>, document.body);: Uncaught ReferenceError: React is not defined

Can we see the vite config and tsconfig?

FjordWarden•2y ago

Vite is just this:

import { defineConfig } from 'vite';
import solidPlugin from 'vite-plugin-solid';

export default defineConfig({
    plugins: [solidPlugin()],
});

import { defineConfig } from 'vite';
import solidPlugin from 'vite-plugin-solid';

export default defineConfig({
    plugins: [solidPlugin()],
});

I dont have tsconfig ATM, does this matter?

Ah, you're doing plain javascript? Hmm

FjordWarden•2y ago

yes, well with jsx

foolswisdom•2y ago

I do believe we've had this issue with the js templates before Need to check the discord history / github issues

foolswisdom•2y ago

Try adding this jsconfig https://github.com/solidjs/templates/blob/master/js/jsconfig.json

GitHub

templates/jsconfig.json at master · solidjs/templates

Yea I've upgraded and downgraded vite and solid in all sort of combinations, at the end I just used one of the solidjs template, don't know what was wrong with my setup but that is what js development is in 2023
