JS/(X) import: to import React components? - phoenix-framework

I want to import a React component from a jsx file in a template and render it in the template with ReactDOM. Later in production I would only want to ship react and all the dependencies of the component only when a site is loaded that has that component.
I have created a React component like this:
editor.jsx
import * as React from "react";
import {Editor} from "draft-js-plugins-editor";
const plugins = [];
export class EditorComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
editorState: EditorState.createEmpty(),
};
}
onChange(editorState) {
this.setState({
editorState,
});
}
render() {
return (<Editor
editorState={this.state.editorState}
onChange={this.onChange}
plugins={plugins}
/>);
}
}
http://www.phoenixframework.org/docs/static-assets suggests the require syntax for accessing module exports. So I added the following to my template <script>const editor = require("web/static/js/editor").EditorComponent</script>. This does not work though, because the browser cannot interpret require (or brunch does not pick it up).
I configured brunch like so:
plugins: {
babel: {
// Do not use ES6 compiler in vendor code
ignore: [/web\/static\/vendor/],
presets: ["es2015","react"]
}
},
modules: {
autoRequire: {
"js/app.js": ["web/static/js/app"],
"js/editor.jsx": ["web/static/js/editor"]
}
},
I am a bit lost here. How can this be done?

One idea that pops to mind is to create a JS file and import it in the template you want with a <script> tag. In the same template create an empty <div id=editor>. Then, in the JS file import React and ReactDOM and the component you want and use something like this:
ReactDOM.render(
<Editor/>,
document.getElementById("editor")
)
However, I'm not sure I understand your problem correctly.

Open Telemetry for react and vanilla JS projects

Can someone help me understand if there is a way to configure open Telemetry on the client side for react and vanilla JS projects all I want to do is to console the traces of fetch call that are being made from the browser.
Most of the documentation I see is only for nodejs. Pls pinpoint a documentation if there are any?
The documentation gives a common guide for Javascript. What you do for you React would be same as what you do for Node.js or even simple JS scripts.
Just follow the documentation. Create and export a tracer:
import { ZoneContextManager } from '#opentelemetry/context-zone';
import { registerInstrumentations } from '#opentelemetry/instrumentation';
import { DocumentLoadInstrumentation } from '#opentelemetry/instrumentation-document-load';
import { FetchInstrumentation } from '#opentelemetry/instrumentation-fetch';
import { UserInteractionInstrumentation } from '#opentelemetry/instrumentation-user-interaction';
import { XMLHttpRequestInstrumentation } from '#opentelemetry/instrumentation-xml-http-request';
import { ConsoleSpanExporter, SimpleSpanProcessor } from '#opentelemetry/sdk-trace-base';
import { WebTracerProvider } from '#opentelemetry/sdk-trace-web';
const setupTracer = () => {
const provider = new WebTracerProvider();
provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.register({
// Changing default contextManager to use ZoneContextManager - supports asynchronous operations - optional
contextManager: new ZoneContextManager(),
});
// Registering instrumentations
registerInstrumentations({
instrumentations: [
new DocumentLoadInstrumentation(),
new UserInteractionInstrumentation(),
new XMLHttpRequestInstrumentation(),
new FetchInstrumentation()
],
});
}
export default setupTracer;
Import the tracer like this in your app's entry point (usually index.js):
setupTracer();
ReactDOM.render(<App />, document.getElementById('root'));

Getting sass css modules to show up when using enzyme with gatsby

So I'm having issues when I use enzyme to test a component thats using css modules. Or should I say filename.module.scss
Whats happening when I do something like:
const wrapper = shallow(<MyComponent {...data}/>);
console.log('wrapper = ', wrapper.debug());
My debug works and shows my component structure with all my divs in there. The issue is none of my styles are getting added durning running tests. But when I run Gatsby develop the styles are getting added. So just to be clear only in test mode do I not see the styles added to my component!!!
MyComponent.js
import React, { Component } from 'react';
import styles from ‘./MyComponent.module.scss';
class MyComponent extends Component {
render() {
const {
name,
} = this.props;
return (
<React.Fragment>
<div className={styles.header}>
<div className={styles.name}>{name}</div>
</div>
</React.Fragment>
);
}
}
My debug is showing all styles as undefined which is driving me crazy as I can't test based on style name if a div exists.
Here is my package setup for jest.
"jest": {
"moduleNameMapper": {
"\\.(css|scss)$": "<rootDir>/.jest/styleMock.js"
},
"setupFiles": [
"<rootDir>/.jest/setupFiles.js"
]
}
For anyone else running into this issue.
npm install identity-obj-proxy
then add this to your package.json
"jest": {
"moduleNameMapper": {
".+\\.(css|styl|sass|scss)$": "identity-obj-proxy"
},
"setupFiles": [
"<rootDir>/.jest/setupFiles.js"
]
}
Hope this helps someone.

Please help me
I had a similar problem with another third party library (ngx-treeview) and I also was only getting the html component empty and with no errors in the javascript console.
It was solved after importing the third party library properly following the JHipster project structure. If you want to use an external module in more than one module component, which is common, you need to configure it in shared-libs.module.ts and also add it to imports and to the exports on its #NgModule configuration.
src\main\webapp\app\shared\shared-libs.module.ts
import { NgModule } from '#angular/core';
import { FormsModule } from '#angular/forms';
import { CommonModule } from '#angular/common';
import { NgbModule } from '#ng-bootstrap/ng-bootstrap';
import { NgJhipsterModule } from 'ng-jhipster';
import { InfiniteScrollModule } from 'ngx-infinite-scroll';
import { CookieModule } from 'ngx-cookie';
import { FontAwesomeModule } from '#fortawesome/angular-fontawesome';
import { TreeviewModule } from 'ngx-treeview';
#NgModule({
imports: [
NgbModule.forRoot(),
NgJhipsterModule.forRoot({
alertAsToast: false,
i18nEnabled: true,
defaultI18nLang: 'en'
}),
InfiniteScrollModule,
CookieModule.forRoot(),
FontAwesomeModule,
TreeviewModule.forRoot() // new third party lib import
],
exports: [FormsModule, CommonModule, NgbModule, NgJhipsterModule,
InfiniteScrollModule, FontAwesomeModule,
TreeviewModule] // new third party lib export
})
export class MyProjectSharedLibsModule {}
Share-libs module is generated by Jhipster and it is by default imported in shared.module which is imported by app.module and also the other modules that are created at start by Jhipster. For more about project structure: https://www.jhipster.tech/using-angular/
However, if you create a new angular module component you need to add the shared module in the imports to be able to use the third parties libraries there.
#NgModule({
...
imports: [MyProjectSharedModule,
RouterModule.forChild([HOME_ROUTE])],
..
})
export class MyProjectAnotherModule {}

Could not find a declaration file for module 'material-ui/styles/MuiThemeProvider'?

I'm trying to use the react material-ui theme having installed it from npm, I get the following errors when I include 'import MuiThemeProvider from "material-ui/styles/MuiThemeProvider";' in boot-client.tsx:
TS7016: Could not find a declaration file for module
'material-ui/styles/MuiThemeProvider'.
'W:/web/WebFront/node_modules/material-ui/styles/MuiThemeProvider.js'
implicitly has an 'any' type. Try npm install
#types/material-ui/styles/MuiThemeProvider if it exists or add a new
declaration (.d.ts) file containing declare module
'material-ui/styles/MuiThemeProvider';
I've tried both suggestions to no avail including running the command: npm install -D #types/material-ui.
My #types folder in node_modules exists with the relevant types.
Here is the code where I'm trying to use it:
import './css/site.css';
import 'bootstrap';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import { AppContainer } from 'react-hot-loader';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'react-router-redux';
import { createBrowserHistory } from 'history';
import configureStore from './configureStore';
import { ApplicationState } from './store';
import * as RoutesModule from './routes';
let routes = RoutesModule.routes;
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
// Create browser history to use in the Redux store
const baseUrl = document.getElementsByTagName('base')[0].getAttribute('href')!;
const history = createBrowserHistory({ basename: baseUrl });
// Get the application-wide store instance, prepopulating with state from the server where available.
const initialState = (window as any).initialReduxState as ApplicationState;
const store = configureStore(history, initialState);
function renderApp() {
// This code starts up the React app when it runs in a browser. It sets up the routing configuration
// and injects the app into a DOM element.
ReactDOM.render(
,
document.getElementById('react-app')
);
}
renderApp();
// Allow Hot Module Replacement
if (module.hot) {
module.hot.accept('./routes', () => {
routes = require<typeof RoutesModule>('./routes').routes;
renderApp();
});
}
Ok I figured it out, in tsconfig.json under 'compilerOptions' visual-studio by default had its types set to ["webpack-env"], I needed to add "material-ui" to it or optionally just remove it: https://www.typescriptlang.org/docs/handbook/tsconfig-json.html
Use the default import from the same path.
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider'
The solution that worked for me which is med's answer above which I explain in more detail below.
Open the tsconfig.json file. Add "types":"material-ui", within "compilerOptions": {}
as in
"compilerOptions": {"types":"material-ui"}

Everything in your code snippets looks good except the part with the HomeComponent template, that Component declaration should look like this:
#Component({
selector: "home",
template: `<Label text="hello"></Label>`,
})
export class HomeComponent {
constructor(private router: Router){
}
}
The reason behind this is the fact that in NativeScript there is not webview it is all native components. So in order for your "hello" text to be rendered you need to use the NativeScript Label. This is all true for NativeScript + Angular 2. Your code snippets work correctly on Angular 2 web because the web browser knows how to render that text, on the other hand NativeScripts Angular 2 renderer does not know how to render a text directly because on iOS and Android there is not such rendering and you need to tell it how via the Label tag.
In the index.html, you have to put <selector-for-the-page></selector-for-the-page> You might have different selector.
