Similar to Access React Context outside of render function but I am looking to add a way of extending Alert.alert so that it will use the color scheme from theme.
const { colorScheme } = useTheming();
...
Alert.alert(t`logout`, "Are you sure you want to logout?", [
{
text: "No",
},
{
style: "destructive",
text: "Yes",
onPress: logoutAsync,
},
], {
userInterfaceStyle: colorScheme
});
I just want it so that the color scheme does not need to be added in.
I started with
import { Alert as RNAlert } from 'react-native'
export class Alert implements RNAlert {
static alert(...) {
// how do I get the data from the context?
}
static prompt(...) {
}
}
This isn't a proper answer yet since I don't wrap the Alert object, but this is the closest I have gotten.
import { useCallback } from 'react';
import { Alert as RNAlert, AlertButton, AlertOptions } from 'react-native';
import { useTheming } from "./ThemeContext";
export function useAlert(): RNAlert {
const { colorScheme } = useTheming();
const alert = useCallback((title: string, message?: string, buttons?: AlertButton[], options?: AlertOptions): void => {
const newOptions = { userInterfaceStyle: options?.userInterfaceStyle ?? colorScheme, ...options }
RNAlert.alert(title, message, buttons, newOptions);
}, [colorScheme])
return { alert, prompt: RNAlert.prompt };
}
The key thing to watch out for is when you're using it with useCallback you have to remember to add the new alert to the dependency list.
const { alert } = useAlert();
...
const handleLogout = useCallback(() => {
alert(t`logout`, "Are you sure you want to logout?", [
{
text: "No",
},
{
text: "Yes",
onPress: logoutAsync,
},
]);
}, [logoutAsync, alert]);
I am able to fetch the list which we see on the landing screen of the site-content. However, when I am trying to fetch data by finding a particular item by its title I get an error CANNOT FIND LIST 'EmployeeList' IN THE URL.
I have built a React Web-part and here are the files and code
ListOfSprintStories.tsx
private _getListData(): Promise<ISPLists> {
return this.props.context.spHttpClient.get(this.props.context.pageContext.web.absoluteUrl + `/_api/web/lists/GetByTitle('EmployeeList')/Items`, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
return response.json();
});
}
private _renderListAsync(): void {
// Local environment
if (Environment.type === EnvironmentType.Local) {
this._getMockListData().then((response) => {
this.setState({ finalList: response.value });
});
}
else if (Environment.type == EnvironmentType.SharePoint ||
Environment.type == EnvironmentType.ClassicSharePoint) {
this._getListData()
.then((response) => {
console.log('======>', response.value)
this.setState({ finalList: response.value });
});
}
}
componentDidMount() {
this._renderListAsync()
}

I have followed the documentation.

I was able to fetch the complete site content list(Document library), but when I am trying to fetch a particular list using getByTitle('EmployeeList'), it fails.
Here is the error message:
{"error":{"code":"-1, System.ArgumentException","message":"List 'EmployeeList' does not exist at site with URL 'https://myTenant.sharepoint.com'."}}
Please Advice.
Issue fixed: The WebPart was working fine locally by fetching data from _getMockListData.
However, it wasn't when I was trying to test the WebPart on the https://MyOffice365.sharepoint.com/sites/**InCorrectSPSite**/_layouts/15/workbench.aspx
I later noticed that I was pointing to wrong SP-site.
I want to display data from API with highcharts but still get an error because highchart config declared outside the class app and data fetched inside class app.
It works if use static data,

const config = {
rangeSelector: {

},
title: {
text: 'aAAPL Stock Price'
},
series: [{

}
}]
};
class App extends Component {
render() {
return (
<div className="App" />
);
}
}
render(<ReactHighstock config={config}/>,
document.getElementById('root'));
With example above, two variable data and config placed outside the class app, so i think it's not problem.
But if i want to fetch data from API, the data placed inside the class app and config still outside class app.
So i get an error 'data is not defined'
here is the link
import React, { Component } from 'react';
import { render } from 'react-dom';
import ReactHighstock from 'react-highcharts/ReactHighstock';
import './style.css';
const config = {
rangeSelector: {
selected: 1
},
title: {
text: 'aAAPL Stock Price'
},
series: [{
name: 'AAPL',
data: data,
tooltip: {
valueDecimals: 2
}
}]
};
class App extends Component {
constructor() {
super();
this.state = {
dataResults: [],
}
}
componentDidMount() {
this.getData();
}
getData = () => {
fetch('https://cdn.rawgit.com/highcharts/highcharts/057b672172ccc6c08fe7dbb27fc17ebca3f5b770/samples/data/usdeur.json')
.then(res => res.json())
.then(data => {
this.setState({
dataResults: data
});
});
}
render() {
return (
<div className="App" />
);
}
}
render(<ReactHighstock config={config}/>,
document.getElementById('root'));
How to use highcharts with fetched data from API?
Your App component is currently not part of your DOM as you're rendering ReactHighstock as a root component. One solution would be to render the chart inside the App component and pass the data dynamically:
const getConfig = data => ({
rangeSelector: {
selected: 1
},
title: {
text: 'aAAPL Stock Price'
},
series: [{
name: 'AAPL',
data: data,
tooltip: {
valueDecimals: 2
}
}]
});
class App extends Component {
constructor() {
super();
this.state = {
dataResults: [],
}
}
componentDidMount() {
this.getData();
}
getData = () => {
fetch('your_endpoint_url')
.then(res => res.json())
.then(data => {
this.setState({
dataResults: data
});
});
}
render() {
const { dataResults } = this.state;
const chartConfig = getConfig(dataResults);
return (
<ReactHighstock config={chartConfig}/>
);
}
}
render(<App/>,
document.getElementById('root'));
You should of course handle a use case where the data has not been fetched yet and display a placeholder.
I started to integrate a WYSIWYG into a blog project, I'm using Quill for this (I had no experience with it before). I was able to customize my editor the way it was required, what I don't understand is how to deal with text format and embed videos. I have two fields in my post form, "preview" and "content" (two quill editors) while introducing the text I can give format to it (header, italic, underline...etc) and when click the embed video option the editor allows me to add the link and visualize the embed video in that moment. When I press my save button it stores the post in my db but in my single post page I visualize all the fields without format (header, italic, underline...etc) and also no embed video. How can I give format and show the video? Any help would be appreciated.
I read the Quill documentation and tried to understand how to deal with this using deltas but I don't know how to make this work.
I'm using Meteor + React, this is my code (I'll show only relevant code):
This is my lib, quill.jsx
import React, { Component } from 'react';
import QuillLib from './vendor/quill.js';
import { ud } from '/helpers/lib/main.jsx';
class Quill extends Component {
constructor(props) {
super(props);
this.id = ud.shortUID();
}
componentDidMount() {
const that = this;
const toolbarOptions = [
[{ font: [] }],
[{ header: 1 }, { header: 2 }],
[{ header: [1, 2, 3, 4, 5, 6, false] }],
[{ align: [] }],
['bold', 'italic', 'underline', 'strike'],
['blockquote', 'code-block'],
[{ script: 'sub' }, { script: 'super' }],
[{ indent: '-1' }, { indent: '+1' }],
[{ color: [] }, { background: [] }],
['video'],
['image'],
];
const quill = new QuillLib(`#quill-editor-container-${this.id}`, {
modules: {
toolbar: toolbarOptions,
},
theme: 'snow',
});
const content = this.props.content;
quill.setContents(content);
quill.on('text-change', (delta) => {
if (that.props.onChange) {
that.props.onChange(quill);
}
});
}
render() {
return (
<div className="wysiwyg-wrapper">
<div id={`quill-editor-container-${this.id}`}></div>
</div>
);
}
}
export default Quill;
This is my input form component, list.jxs
import { Meteor } from 'meteor/meteor';
import { PostSchema } from '/modules/blog/lib/collections.jsx';
import Quill from '/modules/quill/client/main.jsx';
export class BlogCategory extends Component {
constructor(props) {
super(props);
this.state = {
post: {
content: '',
preview: '',
},
};
this.onPreviewChange = this.onPreviewChange.bind(this);
this.onContentChange = this.onContentChange.bind(this);
}
onPreviewChange(content) {
this.state.post.preview = content.getText();
this.setState(this.state);
}
onContentChange(content) {
this.state.post.content = content.getText();
this.setState(this.state);
}
save() {
const content = this.state.post.content;
const preview = this.state.post.preview;
const post = new PostSchema();
post.set({
content,
preview,
});
if (post.validate(false)) {
const id = post.save();
}
console.log(post.getValidationErrors(false));
}
renderCreatePostForm() {
let content;
if (this.state.showForm) {
content = (
<form action="">
<Quill
content={this.state.post.preview}
onChange={this.onPreviewChange}
/>
<Quill
content={this.state.post.content}
onChange={this.onContentChange}
/>
</form>
);
}
return content;
}
render() {
let content = (
<div className="col-xs-12">
{this.renderActions()}
</div>
);
if (!this.props.ready) {
content = <p>LOADING...</p>;
}
return content;
}
}
export default createContainer(() => {
const handleValidPost = Meteor.subscribe('posts');
return {
ready: handleValidPost.ready(),
posts: PostSchema.find({}).fetch(),
};
}, BlogCategory);
And finally my collections.jsx
import { Mongo } from 'meteor/mongo';
export const PostCollection = new Mongo.Collection('Posts');
export const PostSchema = Astro.Class({
name: 'PostSchema',
collection: PostCollection,
fields: {
content: {
validator : Validators.and([
Validators.required(),
Validators.string(),
Validators.minLength(3)
])
},
preview: {
validator : Validators.and([
Validators.required(),
Validators.string(),
Validators.minLength(3)
])
},
}
});
While getting Quill contents by getText, you lost your text format and video information. Using getText, all non-string data will be omitted. Quill data are defined as Delta (which is a JSON object).
You can fix this by updating your onPreviewChange and onContentChange to use getContents instead of getText. Save these Delta to DB and load it again.
onPreviewChange(content) {
this.state.post.preview = content.getContents();
this.setState(this.state);
}
onContentChange(content) {
this.state.post.content = content.getContents();
this.setState(this.state);
}
